SVE flocculators provide engineers and water treatment facilities with well designed, well crafted, flocculator systems engineered for long life and minimal maintenance. Our Flocculator provides gentle agitation by slow moving paddles. This action serves to break up the mass rotation of liquid and promote mixing. The specially designed flocculating paddles enhance flocculation of the feed solids. Agglomeration of the destabilised colloids is achieved as a result of particulate transport in the flocculation compartment. Increased particle contact will promote floc growth and aids faster settling. Our flocculators are available in your choice of horizontal or vertical configurations for all water applications.

A storage tank is a container, usually for holding liquids. Storage tanks operate under no (or very little) pressure, distinguishing them from pressure vessels. Storage tanks are often cylindrical in shape, perpendicular to the ground with flat & Chronicle bottoms. Storage tanks are available in many shapes vertical and horizontal cylindrical, open top and closed top, flat bottom, cone bottom, slope bottom and dish bottom. Large tanks tend to be vertical, cylindrical, or to have rounded corners (transition from vertical side wall to bottom profile), which help in withstanding hydraulic hydrostatically induced pressure of contained liquid.

Most container tanks are used for handling liquids during transportation and are designed to handle varying degrees of pressure.

A screen is a device with openings for removing bigger suspended or floating matter in sewage which would otherwise damage equipment or interfere with satisfactory operation of treatment units.

Types of Screens

Coarse Screens:Coarse screens also called racks, are usually bar screens, composed of vertical or inclined bars spaced at equal intervals across a channel through which sewage flows. Bar screens with relatively large openings of 75 to 150 mm are provided ahead of pumps, while those ahead of sedimentation tanks have smaller openings of 50 mm.
Bar screens are usually hand cleaned and sometimes provided with mechanical devices. These cleaning devices are rakes which periodically sweep the entire screen removing the solids for further processing or disposal. Hand cleaned racks are set usually at an angle of 45 to the horizontal to increase the effective cleaning surface and also facilitate the raking operations. Mechanical cleaned racks are generally erected almost vertically. Such bar screens have openings 25% in excess of the cross section of the sewage channel.

Medium Screens:Medium screens have clear openings of 20 to 50 mm.Bar are usually 10 mm thick on the upstream side and taper slightly to the downstream side. The bars used for screens are rectangular in cross section usually about 10 x 50 mm, placed with larger dimension parallel to the flow.

Fine Screens:Fine screens are mechanically cleaned devices using perforated plates; woven wire cloth or very closely spaced bars with clear openings of less than 20 mm. Fine screens are not normally suitable for sewage because of clogging possibilities.

Mechanical Multi Rake Bar Screen is a mechanically cleaned screen suitable for inlet works of treatment plants, pumping stations and inlet water structures. The screen captures solid materials which otherwise would be harmful to the following process and to the downstream equipment.

Operation:
Thus the operation can be adjusted to the incoming flow. A level sensor is installed in the channel in front of the screen. The screen starts when a pre-set water level is reached and operates until the water level is below the pre-set value. The cycle is repeated when the level is reached again. In operation, sewage flows though the inclined screen, approaching from the upstream side and after passing through the screen, departing on the downstream side. The screen is periodically raked by a mechanized comb system which is actuated either by level switches mounted in the channel upstream of the screen or by time clock. A doctor blade at the top of the comb travel removes the screenings collected by the moving combs. The moving combs are suspended between two endless side chains, which are driven through a head shaft, and sprockets. The gear motor and moving comb system is protected from damage caused by jamming by a torque overload coupling with a micro switch. The screenings removed from the doctor blade drop onto a skid plate, which transports the screening down to a container, belt conveyor or sluice pipe.

Benefits:

• Fine to coarse screen with low head loss
• Removal of extremely high screenings loads
• Low height above operating level
• Frame-mounted bar rack for exact rake engagement and reliable cleaning
• Mechanical overload-prevention and automatic reversion

Vertical screen is a compact and simple unit used for separation and handling of screenings in sewage treatment plants as well as industrial sites. The vertical screen combines sieving, washing and pressing functions in one unit.

Waste water is screened through the lower sieve part of the unit installed inside a channel or a tank. The separation can be done with a perforated plate or with a wedge wire. The sieving element is shaped as a trough equipped with a spiral inside, conveying the captured separated screenings. The spiral is fitted with a brush inside the sieving through to prevent clogging.

The enclosure contributes to a good working environment and it gives a good conveying ability. Inside the conveying section the screenings are washed and conveyed to the discharge end on top. The washing water, used to wash out the organics from the screenings, is added in the opposite direction to the spiral movement. The screenings are shredded into pieces at the discharge in order to eliminate large compact screenings that can cause problems at incineration.

The conveyed screenings are dewatered up to 45% before being shredded into smaller pieces and finally discharged.

Circular tanks require careful design of the inlet stilling well (inlet buffer) to achieve a stable radial flow pattern without causing excessive turbulence in the vicinity of the central sludge hopper.

The removal efficiency of the chain and flight type collector mechanism is much higher than that of bridge type mechanisms. This is due to the large number of flights. Moreover, the power consumption and maintenance cost of these devices are minimal. These mechanisms can be assembled with non-metallic components including Collector Chains, Head and Idler Shaft Sprockets and Scrappers, which not only ensure easier erection due to their light weight but also contribute to making the product, have a longer life. These Scrappers are driven through the collector chains on both ends of the tank and in-turn are carried on the sprocket mounted on the solid stainless steel shafts running across the tank width, which are supported on the tank walls
