Preliminary TreatmentRemoval of waste water constituentssuch as rags, sticks, floatable grit, andgrease that may cause maintenance or operational problem with the treatment operations, processes, and ancil1ary systems 4.
Primary TreatmentRemoval of a portion of the suspended solids and organic matter from the wastewater. Advanced Primary Treatment Enhanced removal of suspendedsolids and organic matter from the wastewater. Typically accomplished by chemical addition or filtration known as Coagulation and Flocculation.
Disinfection is also typically included in thedefinition of conventional secondary treatment 9. Secondary Treatment with Nutrient Removal Removal of biodegradable organics, suspended solids, andnutrients nitrogen phosphorus, or both nitrogen and phosphorus Removal of residual suspended solids after secondary treatment ,usually by granular medium filtration or micro screens.
Disinfection isalso typically a part of tertiary treatment. Nutrient removal is often included in this definition Tertiary TreatmentTertiary treatment consists of followingprocesses and units. Primary Treatment ProcessSedimentation is primary treatmentProcess.
Sedimentation is a physical watertreatment process used to settle outsuspended solids in water underthe influence of gravity. Typical Primary Treatment Plantwith preliminary treatment process Sedimentation Tank Activate Sludge ProcessIn activated sludge process wastewatercontaining organic matter is aerated in anaeration basin in which micro-organismsmetabolize the suspended and solubleorganic matter.
Classification of Stabilization PondsStabilization ponds may be aerobic, anaerobic or facultative. Aerobic ponds are shallow ponds with depth less than 0. Such ponds develop intense algal growth. Anaerobic ponds are used as pre-treatment of high strength wastes. Such ponds are constructed with a depth of 2. Facultative pond functions aerobically at the surface while anaerobic conditions prevail at the bottom. They are often about 1 to 2 m in depth.
The aerobic layer acts as a good check against odour evolution from the pond. Oxidation DitchThe oxidation ditch is a modified formof "extended aeration" of activatedsludge process.
The ditch consists of along continuous channel oval in shapewith two surface rotors placed acrossthe channel. A Typical Oxidation Ditch A View of Oxidation Ditch Tertiary TreatmentProcessTertiary treatment process consists of followingprocess.
