2. WATER TREATMENT Before UseAfter Use  Filtration  Softener  R.O.  D.M. STPETP For the purification of mixture of human & other domestic waste. For the purification of industrial waste water.

3. What is STP ?  STP offers a facility for treating waste disposed off through drains and sewers. It is used to remove materials that damage water quality and threaten public health.  It is designed to provide a POLLUTION FREE ENVIRONMENT and deals with RECYCLING & CONSERVATION OF WATER.

4. CHARACTERSTIC OF EFFLUENT PARAMETERSINLET EFFLUENT OUTLET EFFLUENT (After treatment) 1. pH 5.5-9.06.5-8.5 2. BOD(mg/l) 35010 3. COD (mg/l) 45060 4. TSS (mg/l) 40010 5. Oil & Grease (mg / l) 505

7. Treatment Scheme (A) Physical Treatment : - Screening and Oil & grease trap. (B) Biological Treatment : - Formulation-deterioration of organic substances by action of enzymes that are secreted by microorganism. These are two ways of controlling & removal of pollutant from effluent :  Aerobic Process  Anaerobic Process (C) Tertiary Treatment : - Advance treatment process, includes removal of suspended matter from waste water as well disinfection.

8.  oil and grease trap chambers are provided for removal of free floating oil and grease. Oil & Grease Trap  Fat, Oil and Grease (FOG) is Long Chain Fatty Acid which is difficult to degrade. Condition in Grease Traps is adverse for natural bacteria to survive. That is why FOG needs to be regularly scraped. Two Type of Oil & Grease Trap: ( 1 ) Manual – Civil Tank Separation System ( 2 ) Mechanical - Oil Skimmer Different Component of STP

9. Bar Screen: It is used for removal of floating solid material.

10. Equalization Tank : Aids in homogenization of waste water.

11. Biological Treatment : Removal of Organic loads MBBR Media

12. Secondary Tube Settler : Used in solid- liquid separation in secondary sedimentation Tube Settler

13. Chlorine Contact Tank : Chlorination for disinfection of pathogens

14. Tertiary Treatment:  MGF (Multigrade Sand Filter)  ACF (Activared Carbon Filter) (a) Multi Grade Sand Filter: used for removal of:-  suspended solids.  Dirt  Iron  Silt density

15. (b) Activated Carbon Filter : Used for removal of Odour & Colour.

16. FILTER PRESS : Sludge dewatering equipment  It is a liquid-solid separation device used to reduce the volume &Weight of a slurry waste by separating liquid filtrate and solid filter cake.
