WSPs are highly efficient, simple to construct, low cost and easy to operate. of several wastewater treatment processes and the design of the sludge treatment and disposal units. Stabilization ponds, in turn, are large lagoons where wastewater is stored for long periods to allow a wide range of microorganisms to break down organic matter and sludge is not returned. 19. The term "best waste stabilization pond technology" means a suspended solids value, determined by the Regional Administrator (or, if ap- propriate, the State Director subject to EPA approval), which is equal to the effluent concentration achieved 90 per- cent of the time within a State or ap- propriate contiguous geographical area by waste . WSPs are capable of removing organic matter with efficiencies similar to the activated sludge process and all kind of pathogens. For a more detailed discussion, reference should be made to Gloyna, Hawkes and Mara & Pearson (1-3). Waste Stabilization Ponds (WSPs) are large, man-made water bodies. Waste Stabilization Ponds(WSPs) •Waste stabilization ponds (WSP) are shallow manmade basins into which wastewater flows and from which, after a retention time of several days a well treated effluent is discharged. It uses microorganisms like bacteria, algae and light energy (sunlight) to stabilize the wastewater. Waste stabilization ponds can be used alone or in combination with other wastewater treatment processes. Types of Stabilization Ponds 1.2.1 Anaerobic ponds Anaerobic ponds receive such a high organic loading (>100 g BODSper m3per day) that they are devoid of dissolved oxygen. The wastewater is allowed to remain in the WSP for a certain period of time where, microorganisms aided by the forces of nature act on the organic matter and thereby an effluent acceptable by the quality standards is produced. The purifying action in an oxidation pond can be explained because of a unique relationship between bacteria and algae in shallow ponds. This manual provides the waste stabilization pond operator with the basics necessary for the treatment of wastewater in stabilization ponds.
