The Sequencing Batch Reactor (SBR) is a derivative of activated sludge process designed to operate under non-steady state conditions. Like extended aeration or other activated sludge process it involves the biological process, microorganisms and mechanical aeration system for aeration along with air distributors and diffusers. However the major difference in involved is in operation of treatment which is carried out in batches in cyclic manner. In SBR configuration all related processes of Aeration, Settling, Decanting are carried out in same basin and eventually this reduces construction cost which is very essential in larger systems. The most important component of SBR process is decanting system. The various type of decanters are used for process like Floating gravity type, rake arm type, floating funnel type and slotted pipe type decanters. The process is operated in batch manner and hence it is vary suitable for industrial wastewater and high flow domestic wastewater. The added advantages are it provides BNR ( biological nutrients removal) and completely digested sludge which makes sludge treatment process easier.SBR is modern wastewater treatment system which involves use of automation in operation. The control of cyclic batch operation is programmed in PLC or SCADA. The instruments involved in process helps to transmit appropriate signal and control the system. The automation of system reduces the number of operator skill and attention requirement and hence improves output quality of treated effluent.

Submerged Aerobic Fixed Film Reactor (SAFF) is a cost-effective method of waste water treatment and sewage sanitation that is primarily used in residential and commercial complexes. SAFF process is attached growth type aerobic biological process which uses corrugated inert UV stabilized PVC media. Unlike other aerobic processes of suspended growth principally it provides higher mechanical surface area due to corrugation on media surface. This higher surface area helps biomass microbes for rapid digestion of biomass. The structured SAFF media arranged in reactor is fixed with bottom support arrangement.

Degasser breaks weak carbonic acid into carbondioxide and water. The unit operation used is stripping. The weak acid, either from weak acid cation or strong acid anion is introduced from the top of the degasser column. The Degasser column has ballrings to increase the contact area.Air is blown from the bottom of the degasser tower. The air will split the Carbonic acid into carbondioxide and water , Co2 will be vented of from the degasser tower and the water will be collected in a tank. Degassed tower considered in a DM water system or in D Alclysing system when the alcalynity in the water is very high and the pay back of degasser tower is favorable.

Water softening is the removal of calcium, magnesium, and certain other metal cations in hard water. The resulting soft water is more compatible with soap and extends the lifetime of plumbing. Water softening is usually achieved using lime softening or ion-exchange resins. It is widely used in the food & beverage, hydrometallurgy, metals finishing, chemical & petrochemical, pharmaceutical, sugar & sweeteners, ground & potable water, nuclear, softening & industrial water, semiconductor, power, and a host of other industries.

HRSCC uses turbulence and high velocity to reduce silica load in the water apart from deduction of suspended impurities and turbidity. HRSCC requires lesser area and process time and thereby, reduces the initial civil cost of the plant.

As the name suggest Clari Floccution is a combination of clrifier and floculator combined in to clarifier and floculator. Physio chemical reaction of settling and floculation takes place in a clari floculator unit. There is sepearte chamber provided for dossing floculants in the unit. There are many types of Clari Floculators like Central drive, peripheral drive, agigator gate type etc.

Tube / Plate/ Lamella settlers are modern unconventional solid - liquid separation systems units. These settling units due to higher settling area and effective arrangement of multiple tubular channels sloped at an angle of 55- 60 and adjacent to each other, increases the rate of settling. These modern settlers provides particle settling depth that is significantly less than the settling depth of a conventional clarifier, reducing settling times. Tube settlers capture the settleable fine floc that escapes the clarification zone beneath the tube settlers and allows the larger floc to travel to the tank bottom in a more settleable form.

Why Tube Settlers ?

The Tube settler contains inert, non corrosive UV resistant PVC inert media placed in inclined manner and arranged in structured manner with its self interlocking system. The smooth surface , inclined arrangement and adequately designed void space helps large solids, flocs and particulate matter the move downwards of the settler. The tube setters has sharp conical bottom which enables to effective setting and reduces footprint. Due to such arrangement the extra mechanical scrapping arrangement which is usually and integral part of conventional clarifier is not required. This also provides benefit of choice of geometry of settling unit which is very essential during space planning of compact systems. The tube settler's channel collects solids into a compact mass which promotes the solids to slide down the tube channel. Tube settlers offer an inexpensive method of upgrading existing water treatment plant clarifiers and sedimentation basins to improve performance. They can also reduce the tankage/footprint required in new installations or improve the performance of existing settling basins by reducing the solids loading on downstream filters. Made of lightweight PVC, tube settlers can be easily supported with minimal structures that often incorporate the effluent trough supports. They are available in a variety of module sizes and tube lengths to fit any tank geometry, with custom design and engineering offered by the manufacturer.

Advantages of Tube Settlers

The advantages of tube settlers can be applied to new or existing clarifiers/basins of any size:

• Clarifiers/basins equipped with tube settlers can operate at 2 to 4 times the normal rate of clarifiers/basins without tube settlers.
• It is possible to cut/ reduce coagulant dosage by up to half while maintaining a lower influent turbidity to the treatment plant filters.
• Saves electricity as no mechanical and rotating equipment's it also lowers Operational Expenditure(OPEX).
• Less filter backwashing of downstream units equates to significant operating cost savings for both water and electricity.
• New installations using tube settlers can be designed smaller because of increased flow capability.
• Flow of existing water treatment plants can be increased through the addition of tube settlers.
• Tube settlers increase allowable flow capacity by expanding settling capacity and increasing the solids removal rate in settling tanks.
• Extended life of unit as no mechanical or rotating units are involved.
• Inert PVC material has very long life and can be replaced or top-uped easily.

Submerged Aerobic Fixed Film Reactor (SAFF) is a cost-effective method of waste water treatment and sewage sanitation that is primarily used in residential and commercial complexes. SAFF process is attached growth type aerobic biological process which uses corrugated inert UV stabilized PVC media. Unlike other aerobic processes of suspended growth principally it provides higher mechanical surface area due to corrugation on media surface. This higher surface area helps biomass microbes for rapid digestion of biomass.

In the wastewater industry, SAFF Technology is used commonly for commercial and residential sewage sanitation / waste water treatment, particularly for small to medium range flow requirements. The air for process is supplied through mechanical aeration system arrangement which consist of blower and diffusers. The structured SAFF media arranged in reactor is fixed with bottom support arrangement.

Advantage of SAFF process

• MLSS concentration is much higher than what is normally achieved in aeration system of ASP process.
• Higher loading of BOD on the media enables to reduce the aeration tank size. SAFF requires 25-40% lesser tank volume as compared to activated sludge process.
• Cross-corrugation pattern of media ensures that air bubble travels in zigzag fashion, thus increasing the bubble travel path and thereby increasing the oxygen transfer rates.
• SAFF system takes higher shock loads without reducing the plant performance because of large quantity of MLSS available inside the reactor.
• Rate of sludge generation is normally lesser as compared to conventional system.
• Life of SAFF system is long (about 10-15 years) as inert PVC media material is used. Non pressurized system.
• This process is modification of activated sludge process which have eliminated its limitations.
• All these process produces better quality treated wastewater than conventional activated sludge process.
• Easily meets discharge norms.
• Odour problems, maintenance problems, are eliminated.
• High MLSS Less Space required for the treatment.
• SAFF process able to achieve 95-98% BOD reduction.

Due to above advantages the SAFF process is used commonly in package systems where compactness of treatment is key factor.

Membrane Bio Reactor (MBR) is a combination of two basic processes i.e. biological degradation and membrane separation in to a single process where suspended solids and microorganisms responsible for biodegradation are separated from the treated water by membrane filtration unit.

Filtration based on UF or MF membranes is key for solid liquid seperation in MBR process. The Concentration of biomass is maintained very high in MBR systems. due to high MLSS the process reaction time is considerably low and optimum. Usually filtration is carried out by two different methods which defines the types of MBR process i.e. Side stream MBR and submerged MBR.

Both types of MBR's have their unique advantages and sparkle can offer both types of MBR configurations. The systems configurations are chosen by considering the customer requirements and waster characteristics.

The MBR system is considered as most effiecient and modern wastewater treatment technology and known for various advantages over other treatment processes

• Compact design with smallest footprint. MBR process involves higher MLSS hence reaction tank is 75 % smaller than conventional extended aeration process tank.
• Less treatment units required. Low space requirement
• Treated water quality after MBR is excellent as it is directly filtered through ultra filtration or microfiltration membranes.
• No separate tertiary treatment required.
• Rate of sludge generation is normally lesser as compared to conventional system.
• BOD values of treated water is very low and hence waste water can be reused easily.
• Negligible (almost zero) sludge production
• Rapid Startup
• Modular/ Retrofit , system can be enhanced for capacity expansion easily.

Nano filtration is a stage of filtration between UF and RO where semi permeable membrane rejects high molecular weight salts. Nano filtration is essentially used for removal of hardness i.e., calcium and magnesium salts from water. It finds its utility as prefiltration to RO Systems and filtration for boiler feed water. The Principle used is same as that of Reverese Osmosis.

UV System is also one of the maseares for the disinfecteant of water. Water is passed through the UV light, which eliminates bactreia and viruses. UV is an electro magnetic radiation, having radiation from 10nm to 400nm. UV rays penetrate through harmful bacteria in water and eliminate them. Disinfecting through UV light is a very simple and effective method. UV system destroy 99.99% harmful microorganism without adding any chemicals. Since there is no chemical being added water does not change its taste or odour.

Ozone is an unstable molecule which readily gives up one atom of oxygen providing a powerful oxidizing agent which is toxic to most waterborne organisms. It is a very strong, disinfectant that is widely used. It is a very good disinfectant. Ozone is made by passing oxygen through ultraviolet light or a "cold" electrical discharge. To use ozone as a disinfectant, it must be created on-site and dosed in to the water. As compared to chlorine the issue of odour and smell is lesser. Ozone though is a very good disinfectant does not leave any disinfectant in residual water. This may be termed as advantage as well as disadvantage. It is applied as an anti-microbiological agent for the treatment, storage, and processing of foods.
