STP ETP
For the purification of
mixture of human & other domestic
waste.
For the purification of
industrial waste water.
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
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
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.
CONCLUSION
Energy Efficient Plant.
Totally Integrated Zero discharge system.
Compact Mobile Plant requiring very less space.
Treated water re-usable.
Corrosion resistant Plant
User Friendly Plant.
