The Sewage Treatment Plant Incorporates the following operating procedure:
Initial Screening & Oil/Grease Trap.
Equalization.
Sludge Return Process Bio Reactor.
Settling.
Two Step Media Filtration.
Sludge Storage Tank with Aeration Provision.
Sludge Transfer from Settler to Tank & Tank to Out.
Features of the Sewage Treatment Plant:
All the treatment steps are incorporated in underground RCC tank. (Except Filtration).
No Separate Septic Tank Required.
No Open Sludge Handling & nuisance on that account.
Optional Sludge Dewatering System can be Incorporated before storing the Sludge.
Single Panel with all switches for on-off operation at easy to access location.
Optional Mechanical Oil Skimmer can be incorporated to ensure removal of separated oil.
All Pumps & Blowers are provided with “standby” to ensure easy switching if required.
Dry run protection for centrifugal pumps.
C-type ladders in tanks to ensure easy access.
Continuous visits by our engineers during civil work to ensure “ Correct Integration”

Benifits of using STP:
The Sewage Treatment System being proposed by us is SMBR Based technology. Suspended Media Bio Reactor (SMBR) is emerging as a clear choice for STP’s all across the sector for various reasons like:
Less Area Requirement.
No Sludge Recycle, monitoring of F/M ratio etc. hence easy to operate.
Minimal moving parts thus lesser maintenance requirement.
Flexibility to correct the performance by just adding the media in a reactor or increasing the Air quantity.
No more costly replacements
SMBR
Initially, the effluent is passed through the Bar screen, oil & grease trap and an equalization tank.
Oxygen is made available with the help of air grid or diffusers.
As the name suggests this process has suspended media which is available.
The significance of the media is to assist growth during the treatment and also to ensure that the concentration of the required MLSS is maintained.
Following the solid – liquid separation, the liquid then enters the settling chamber.
In this chamber, the suspended solids accumulate at the bottom of the tank which is then eliminated into the sludge holding tank with the help of sludge pumps.
Finally, the raw liquid flows through two filters.
A filter having a specific combination of media like gravel, Pebbles, and filtration sand to ensure filtration.
Followed by Activated Carbon media which acts as the second filter so as to reduce BOD.
Chlorine dosing is done at the outlet of the carbon filter.
