EUROTECK builds total energy systems with guarantees of power in kW and temperature for the need of the customer. The system includes sewer pipe, heat exchanger, connecting pipes, any type of heat pumps (electric, gas motor, absorption), peak boiler, all installations in the energy plant, control systems.

In addition of this variety of opportunities to implementation, there a three new important developments:

• The patent of an Anti-fouling-System to prevent the formation of slime (biofilm).
• The new material developed by Arcelor-Mittal (chrome steel) provides improved thermal conductivity by about 80 percent.
• A supervisory control system for bivalent systems with alternative energy sources.
• We is always ahead in research and development, having invented an anti-fouling system to prevent the formation of an insulating biofilm and a new heat exchanger material with a 80 % better heat conductivity.

Thanks to all these new developments it was possible to increase the heat extraction rate by up to 40%. That means, without the anti-fouling system and without the new ferritic steel, the heat exchanger chains would have to be 40% longer. Together with a bivalent process control system, sewage heat recovery plants now score with a return-on-investment of 2 – 6 years.

Screens are manufactured from stainless steel AISI 304 or AISI 316 on customer demand. The movable and endless filtering mesh consists of hooks and is installed on the screen frame. Filtering mesh openings are 5mm wide by default, but can be adjusted on customer demand. The rectangular frame consists of two longitudinal boards connected by crossbeams. The filtering mesh moves along polymer guides installed on the longitudinal boards of the screen, and is driven by a shaft with drive sprockets located on the top part of the screen.

The shaft is driven by a geared motor. Filtering mesh tension can be adjusted. Wash water nozzles and a drum with radially located brushes are placed on the driven shaft of the geared motor. This motor is installed on top of the screen frame and is designated for the filtering mesh hooks cleaning.

Operating Principle

• The hook type screen retains and removes solids of which the size exceeds that of the filtering mesh openings from the wastewater. Collected solids are moved in an upward direction to the discharge zone by means of the hooks. Here it is discharged into the transporter or waste bin. After the waste is discharged, cleaning of the filtering mesh is performed by wash water from the nozzles, followed by the revolving brushes. In addition, the previous hook line cleans the next hook line at the moment of its overturn.
• The screen operation periodicity depends on the equipment automation scheme.
• Due to the special design of the filtering mesh, a contamination layer is generated onto the working surface and creates an additional filtering effect which allows catchment of particles with sizes less than 5 mm.

Automation

• Screen automation can be done according to different parameters: Wastewater level difference upstream and downstream of the screen.
• Any customized program.
• Alarm systems of the normal operation indication, the emergency stops, the wastewater top level in the channel and others are provided. It is possible to transfer equipment status data to a higher level automated process control system depending on the client’s requirements.
• The screen is supplied with safety device to avoid damage to any screen components.

The safety device stops the screen operation when bulky waste ingress the filtering mesh, or when any other object blocks free plate movement. Light and sound alarms turn on simultaneously when the safety device is active. The screens, together with a conveyor, compacting press and slide gates, are included in a high-performance complex for mechanical wastewater treatment.

Equipping the control system with programmable modules makes it possible to integrate complex sub systems into one system with a common control center and remote dispatching.

Advantages

• Fine mechanical wastewater treatment is achieved due to the narrow filtering mesh spacing, as well as the contaminants layer formation on the screen’s steps Special design of the hooks makes the filtering mesh self-cleaning.
• Reliable and easily operated
• Step screen is manufactured from stainless steel AISI304 or AISI316 (on customers demand) which makes the equipment corrosion resistant

The Advanced Activated Sludge Process or three-stage A2O process consists of a Modified Ludzack-Ettinger (MLE) process for nitrogen removal, with an anaerobic zone in front for phosphorus removal .The process is called A2O since it consists of anaerobic/anoxic/oxic (aerobic) tanks in series. The RAS is recycled to the anaerobic zone. The anaerobic zone is followed by an anoxic zone for nitrogen removal through de-nitrification. IR is recycled from the aerobic zone to the anoxic zone at a rate of 100 to 400 percent of influent. Nitrogen removal is limited by the IR flow and this is achieved by means of IR gates contrary to the heavy duty pumps which consumes high amount of power . This is a relatively simple process to operate. The process has a small footprint.

Features which Makes the A2O Process Advanced

• Incorporation of High Efficiency Triton Type Aerators which have deeper mixing capability up to 10m.

Operating Principle

The operation cycle with the filter plates clamping. The inner voids of plates are joined in the combined chamber space. When reaching a certain pressure value (which ensures the chamber space seal), the external pump feeds slurry into the filter press. This slurry gradually fills the filter press and due to the feed pump pressure , the liquid phase passes through the filter cloth and flows out of the filter press via the internal canal system. The cloth collects a layer of cake, with the thickness depending on the quality of the slurry supplied. This process takes place until the void is completely filled with the cake after which the slurry feed stops.

After filtering the cake in the chamber, it can be further processed to obtain additional effects with washing and drying. During washing the washing fluid is fed into the filter press. This expels the main filtrate from the cake. Washing can be done in several stages along with separation of the wash filtrate by concentration and discharging of the weakest portions for the first stages of the next cycle. Also, washing can be performed with several fluids. Washing is achieved by supplying washing liquids into discharge line from one side of the filter press. This provides conditions for uniform washing of the whole cake area. Washing is very effective in applications that require the maximum phase separation. Multilevel washing achieves good results with the lowest cost in washing fluid.

During the drying process, compressed air passes through the cake in the press, to decrease the cake humidity. As with the washing liquid, air is supplied into the filtrate discharging line from one side of the filter press to ensure uniform drying. Drying is done to reduce the moisture content in the cake for reduction of subsequent heat treatment costs, ensuring the transportation conditions of dried cake or to achieve maximum phase separation in cases when cake washing is impossible.

After filtering and processing, washed and dried cake is discharged from the filter press – the clamping plate is moved to the end position, followed by gaps appearing between the filter plates with the width greater than the cake thickness. Pressed by their own weight, cake fall out through the openings into the receiving bunker or on the removal device.

The auxiliary equipment include:

• Electrically driven cleaner of the clarifier board lane
• Device for mechanical cleaning of clarifier’s tray edges
• Device for collection and removal of floating material from the clarifier’s water surface

The device for collecting and removing floating material consists of the receiving bin, the case, the pipeline and the above water scraper driving floating material to the clarifier board.

The radial suction scraper can be made movable in the vertical plane of the sludge receiver manifold pipe, on customer demand. On the sludge receiving collector’s end, the wheel is installed to accommodate inconsistencies from an uneven clarifier floor.

The Disc Cloth Filter is made up of a drum or alternatively of filter discs mounted on a central hollow shaft. The filtration is done by gravity with an idle machine and uses the level difference between the input and output of the machine. The discs (or the drum) run completely immersed in the water to be treated.

During the filtration phase, the solids are held back by the special polstoff cloth. The minimum water level in the tank containing the filter is controlled by a weir placed on the side of the clean water outlet. With the increase of deposit of solids on the cloth, the hydraulic resistance increases in passing and therefore the difference between the levels of entry and exit.

When a difference of 15 ÷ 20 cm between these levels is reached, it automatically activates the cleaning process of the cloth.

To clean the cloth which is necessary to restore its filtering capacity, the discs (or drum) are rotated slowly. The solids are removed as a result of the backwash passage through the cloth, the water already filtered by a suction pump; this pump is connected to special suction nozzles, which by adhering to the walls of each disc or drum causes the free fiber of the cloth filter to stretch facilitating the release of the sludge particles retained therein.

The contact of the suction nozzle with the cloth filter generates the recompression of the free fibers and the consequent formation of an even filtration panel.

The cloth filter of the drum or disc filters is made of polstoff free fibers (fiber length from 10 to 12 mm and a diameter of 13 to 27 µ fastened to a large weave fabric that serves as support). The type of filtration obtained is comparable to the deep filtration of sand filters and not the surface filtration of the monofilament cloth filters.

Features

• Depth filtration, similar to sand, for high solids load
• Filtration from outside to inside, backwash from inside to outside the discs
• Discs are completely submerged
• No chemical dosing, no tiny nozzles or small holes to be cleaned
• Free Fibre cloth
• Low installed power
• Gravity filtration
• SS 304 filter frame

What it is & How it Works?

• It is PDMS hollow fiber membrane with 0.3 mm diameter & 0.1mm wall membrane
• It is Gas permeable membrane
• Bacteria in the form of bio film grows on the outer surface of the hollow fiber tube (fixed film)
• Air at low pressure (not against water head) is blown the hollow fiber tube, saves power (op ex)
• O2 (oxygen) diffuses through the wall of membrane to the base of Bio film, which is surrounded by anoxic waste water
• Simultaneous nitrification & De-nitrification takes place in the same tank (saves Cap.Ex.) no need of large recirculation of nitrite to nitrate (Op.Ex. saved)
• Ammonia in water diffuses to the base of bio film, where it is nitrified to make Nitrite and Nitrate
• Both Nitrate & nitrite diffuse to surface of Bio film at outer layer, where they are combined with COD & BOD of water & De-nitrify.

Advantages

• MABR offer 95% oxygen transfer efficiency, whereas conventional systems offer around 30%
• No back wash needed as liquid does not pass through the membrane, only gas
• (Air & o2) pass through.
• Air passed through hollow fiber tube, not subjected to head pressure of water level,
• So low pressure @ 150 mBar

With our vast experience in the field of waste water treatment, we provide best in class municipal sewage treatment plant facility which includes common effluent treatment and municipal sewage treatment facility. Our services are rendered keeping CPCB norms and guidelines in check. Contact us for more information.

Operating Principle

Wastewater is fed at the inlet zone of the conical tank and swirls along tank walls by means of the mixing device rotation. Grit slips along the walls of the conical tank and reaches the grit washing unit. Clarified wastewater is directed to the outlet branch for subsequent treatment stages. Grit is washed by pressure water in the grit washing unit. Grit is agitated by the mixer to improve the grit washing process. Washing water is drained to the subsequent treatment stages while the grit is collected at the tank’s bottom. From here it is removed to the discharge zone by the screw conveyor. The grit is discharged into the storage container or onto the transporter.

Advantages

• modular construction is ideal for small wastewater treatment plants
• does not require high capital costs.
• increased efficiency by using tangential motion of the fluid.
• casing manufactured from stainless steel is reliable and durable.

Automation

Automation of the grit chamber operation can be time based. All grit chamber geared motors (mixing devices and transporter) are equipped with electrical protection. Alarm systems of the normal operation indication and emergency stops are provided.

It is possible to transfer equipment status data to a higher level automated process control system depending on the client’s requirements. The screw can be reversed in order to address jams and congestion.

Euroteck is a prominent provider of well-customized STP Revamping work that is highly demanded by industries involved in the treatment of wastewater. The service we offer is successfully completed within the stipulated time frame, therefore highly recognized by our clients.

During the manufacturing process, varied effluents and contaminants are produced. The effluent treatment plants are used in the removal of the high amount of organics, debris, dirt, grit, pollution, toxic, non-toxic materials, polymers, etc., and if it gets increased we need revamping. The ETP plants use evaporation and drying methods, and other auxiliary techniques such as centrifuging, filtration, incineration for chemical processing, and effluent treatment, which retrofit the plant.

The treatment of effluents is essential to prevent pollution of the receiving water. The effluent water treatment plants are installed to reduce the possibility of pollution; biodegradable organics if left unsolved, the levels of contamination in the process of purification could damage bacterial treatment beds and lead to pollution of controlled waters.

Scope of Application of Screw Screens

• Municipal wastewater treatment
• Paper and Pulp industry
• Meat processing industry
• Vegetable and fruit processing plants
• Food industry

Features

• The primary element of the screw screen is its usefulness. It isolates medium and little waste from municipal and industrial wastewater, at that point performs washing, pressing and transportation of the screenings to the garbage removal tank.
• An opened or punctured sifter is introduced at the lower part of the screen. As the wastewater goes through the strainer, the waste is held on the separating surface. The screw is furnished with a brush to clean the strainer in the filtration region. In the upper piece of the screen, there are territories for the screenings washing and pressing.
• Because of the coordinated screenings washing capacity, natural mixtures stay in the wastewater, which adds to the biological treatment measure.
• The shaftless screw prevents blockage, obstructing or sticking of the screen, in any event, when working with stringy materials.
• The utilization of a punctured sifter with little openings takes care of the issue of holding even difficult-to-get impurities, like hair.
• The screen can be outfitted with a gadget for dumping washed and dewatered squander into polyethylene packs, which isn’t just incredibly helpful for additional transportation of waste, yet in addition, forestalls the spread of odors.
• The design solves the issues related with the activity of a huge piece of the extra hardware for wastewater treatment, for example, there are no mind-boggling systems and parts that require consistent and work concentrated support.
• RVO screw screen can be effortlessly coordinated into the current complex of treatment offices and synchronized with different sorts of equipment.
• The screens are intended for use in wastewater with pH = 6.5÷8.5.

The durability of the Screw Screens

• All work is finished by the screw, so there is no critical number of rotating parts. This increases the reliability and durability of the screen.
• The screw is made of wear-safe carbon steel, and a self-cleaning strong brush is introduced nearby the channel sifter.
• The utilization of stainless steel (AISI 304, AISI 316) in the unit gives its strength, which is vital for work in an aggressive wastewater climate.

• System operation: Different works to manage installation through an understanding of the parameter values which define the status of different treatment processes.
• Maintenance of the infrastructure: Ensuring the condition and operation of equipment and facilities which allows treatment with the inflow parameters determined by Legislation.

Application Features of Step Screens:

• Fine wastewater treatment – least dispersing width is 3 mm.
• High throughput capacity
• Self-cleaning separating surface design
• Air-assisted fomentation arrangement of sand silt.
• Step Screen
• Step Screen

Advantages and Benefits of the Step Screens:

• The design adjusts to practically any installation site. At times, blocked holes can be impeded by rubber sealings.
• Activity in the mode of ceaseless lifting and transportation of screenings.
• Narrow slot width and the filtration of the stream by the “cover” of the lifted screenings, which altogether builds the partition effectiveness.
• Self-cleaning of plates without the utilization of assistant components, brushes or washing with water.
• Prevention of screenings’ falling once again into the channel because of the diminished spacings of 1 mm nearby over the channel.
• Low amiability to sand and rock.
• Simple substitution of the sifting surface if there should be an occurrence of harm.
• The utilization of a dependable worm gear engine from the world brand, NORD Drive Systems.
• Slight sheet metal plates with a thickness of 2-3 mm give a high throughput limit of the screen.
• Evacuation of fine silt utilizing a punctured pipe. The pipe is introduced at the lower part of the screen and is utilized to work up silt that can be gathered before the screen.
• Coordination into existing offices for wastewater treatment. Alternatives of robotization and synchronization with different sorts of equipment.
• Mechanical and electrical over-burden protection incase if blocking,

Durability of Step Screens:

• The use of AISI 304 or AISI 316 stainless steel. Additional anti-corrosion treatment – volume etching and passivation.
• Strong housing that is resistant to damage, inaccurate installation or rough transportation conditions.

IFAS (Integrated fixed film activated sludge) is a treatment process, combining suspended and sessile biomass. Equivalent to a conventional activated sludge process, necessary microorganisms for the biological treatment exist in sludge flakes that are suspended in the waste water. In addition a media is placed into the treatment tank in order to attach a part of the biomass (sessile biomass). With the attached growth more biomass is available in the system. More biomass simply means more microorganism and more micros are able to tackle more or higher polluted waste water.
