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.

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.

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

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

Equalization Tank : Aids in homogenization of waste water.

Biological Treatment : Removal of Organic loads

MBBR Media

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

Tube Settler

Chlorine Contact Tank : Chlorination for disinfection of pathogens

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

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

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.
