These Units corrosion resistant and requires minimum maintenance our products are manufactured using superior quality materials under stringent supervision. Effluent can be treated in a number of different ways depending on the level of treatment required. These levels are known as preliminary, primary, secondary and tertiary (or advanced). The mechanism for treatment is divided into three categories: Physical, chemical and biological. Preliminary Treatment. · Preliminary treatment removes in-organic materials and insoluble organic pollutants (i.e., large organic suspended solid matter, grit, O& G) that can be easily collected from the effluent and can damage or clog the pumps or skimmers of primary treatment clarifiers. · All preliminary treatments consist of physical separation techniques by controlling flow rate of effluents. Units in Preliminary Treatment, Screens, Scrapers, Aeration Primary Treatment It consists of temporarily holding the sewage in an inert basin where heavy solids can settle to the bottom where oil, grease and lighter solids float to the surface. The settled material go for sludge treatment in sludge digesters and floating materials are skimmed off and the remaining liquid is passes to secondary treatment. At this stage, over 70% of the suspended solids and 40% of the BOD is removed from the effluent, · Secondary Treatment biological treatment of effluent removes dissolved and suspended organic (bio-degradable) matters by consuming food and convert it into new cell mass, energy and CO2.,Most common micro-organisms are bacteria (aerobic or anaerobic), protozoa and rotifers, least common fungi and algae. This treatment removes almost 70- 90% of BOD and 80- 90% of dissolved solids from effluent. The under flow from the clarifier and the secondary clarifier having a sludge consistency of around 1-1.5% is pumped into the centrifuge for dewatering.
