WATER AND WASTEWATER TREATMENT TECHNOLOGIES Filtration Technologies in Wastewater Treatment S. Vigneswaran, J. Kandasamy and M. Rogerson ©Encyclopedia of Life Support Systems (EOLSS) Figure 1 Diagrammatic section of a rapid sand filter. The entire process of backwashing the filters and restarting the water supply takes about 15 minutes.
The objectives of the chapter are to provide an overview of water treatment and purification roles and technologies, and to introduce terminology that would assist people in understanding the relation of the various technologies to the overall schemes employed in water treatment applications.

Operating Principle. Furthermore, wash water enters from the screw classifier into the bottom of the hopper and, aided by the central stirrer, the grit and sand particles abrade against each other scouring any attached organic matter from their surface. This scouring process is further enhanced by air agitation.

Silica sand low in iron is much in demand for glass, ceramic and pottery use, and for many of these applications clean, white sand is desired. Impurities such as clay slime, iron stain, and heavy minerals including iron oxides, garnet, chromite, zircon, and other accessory minerals must not be present.
Fed from a vortex, aerated grit chamber, detritor tank, or any other means of grit separation either by airlift or grit pump, the SANDWASH TM grit washer utilizes a multistage washing process to remove organics and other larger, lower density objects to be returned to the downstream biological treatment.
Product Description. A rising current manifold on each Eagle Coarse Material Washer provides an upward current of water to assist in removing unwanted materials. Lightweight deleterious materials such as twigs, sticks and coals are floated by the rising current of water and the jigging action of .
Odor Control. At the treatment plant, odor control is very important. Wastewater contains a lot of dirty substances that cause a foul smell over time. To ensure that the surrounding areas are free of the foul smell, odor treatment processes are initiated at the treatment plant.
Description and Working Principle. It is fed either by an air lift pump, pump or pump and cyclone washer/concentrator. Grit laden water is fed via the flanged inlet of the integral decanting hopper where the solids are allowed to settle out. Special baffle plates and inlet/outlet arrangements can be used to remove any remaining floating matter.
The grit washer unit consists of two basic items – grit wash tank and discharge screw. The grit/water mixture is fed in via the inlet flange of the grit wash tank. Organic matter is held in suspension and floated off while the grit is settled in the container.
