Design is on the basis of above parameters, any changes in parameters other than above please inform us. We will not be responsible for the parameters other than this, which can disturb the plant operation. Use of treated water:
For low end purposes such as gardening or can be discharged. Note: For other uses of treated water please consult us. Scheme-
Sewage water is collected in collection tank through bar screen from different lines by gravitational flow. Here the oil and grease is removed by oil skimmer and by conventional way. Then pumped to the aeration tank for biological degradation of biodegradable organic matters. Solid will be separated from liquid in settling tank, which then collects to filter feed sump. Filtrate from here pumped to MGF for removal of traces of suspended particles. Chlorine dosage is ahead to MGF. This then pumped to ACF for removal of traces of color, odor and chlorine. This water can be used for gardening.

CONCEPT OF EFFLUENT TREATMENT PLANT FOR CONSISTENT PERFOMANCE
SCREEN-
Fine screens are mechanically cleaned devices using very closely spaced bars with clear openings of less than 20 mm. Fine screens are used for pretreatment of industrial wastes to remove materials which lead to produce excessive scum or foam on the top of digestion tank contents. Oil skimmer can be used as a pretreatment before filtration of contaminated liquids to be re-used. Oil skimmer is the cheapest and technically effective means of removing floating oil from water and water based solutions, effluents, coolants etc to be reused to minimize process cost. Physical characteristics allow the rotating skimmer mechanism to attract oil and other hydrocarbon impurities from the surface of the fluid. The rotating mechanism (Belt) operating on a motor and pulley system runs through the contaminated liquid to pick up oil from the surface. Floating oil sticks to the skimmer rotating mechanism and is then wiped off efficiently and canalized for collection in waste oil collection tray. Aeration TankAn aerated aeration tank is a basin in which wastewater is treated either on flow or solids recycle. Oxygen is usually supplied by means of aerator of diffused aeration system. The contents of the aeration tank are mixed completely, and neither the incoming solids nor the biological solids produced from waste conversion settle out. Solid return is used to improve the process. Effluent contains is converted into biological tissues. B.O.D. removed efficiency is 95%. Membrane diffuserRetrievable fine bubble Diffused aeratorSimplest way of commission and user Friendly. Economic to other type of aerator. No need of emptying the tank as it can be pulled out. Easy for maintenance. MGF/ACFImproves the water quality. Reliable process in which the total suspended solids, color, odor and total dissolved solids are removed at higher level. The outlet water can be used further for the process. Filter PressFilter press is an efficient equipment to separate solids and liquid in processing and chemical industries. A Filter Pump is applied to feed the mother liquor with solids & liquids through
feed nozzle of the filter press to the chamber formed between the plates and the filter medium, leaving the solid trapped inside and the liquid drained out. Cake that is built in the hollow space between the plates will fall out once the pack is opened.
