Sewage treatment is required for homes, hosing colonies, hospitals, malls and shopping centers, big industries, villages, towns and cities. Various type of treatment plants are available as mentioned at the bottom of this page. Output quality must match having BOD / COD / TSS less then 5 / 10 / 5 ppm respectively. With the use of more soap and detergent only biodegradation can not achieve the results and dosing of chemicals become necessary. Also with population growth space is very precious now and small foot print is requited. Also required is the lowest energy input and maintenance free plant. Shortly reuse of such water will be necessary to meet the water shortage and low salinity water requirement for various purpose.
We provide STP having following features.
1) Providing advanced STP – waste to energy – with primary / Bio Tower / Filtration and reuse of water for Gardening and Toilet flushing and Bio gas Plant for concentrate along with kitchen waste if any
2) Most efficient for removal of Phosphorus and COD for energy
3) An advanced Bio gas system with Special media for concentrated mass
4) Bio Tower with low footprint with Special Media for supernatant
5) Filtration for safe discharge or reuse in toilet flushing etc.
Treatment scheme: For Sewage Water
Screens to remove rags / plastic pouch etc debris
Collection cum equalization with stirrer for anoxic mixing and also chemical mixing
Transfer of wastewater to primary settling system
VACL Flocks – COD reduction dosing system
Settling of solids in high height clarifier unit
Transfer of Concentrated stream to Anaerobic Digester for Bio GAS generation and Use of same in home / canteen. Use of slurry as fertilizer in gardening, So practically zero solid waste.
Transfer of dilute stream to Bio Tower (followed by Biological Extended aeration system with MBBR + IFAS in case of high input COD / BOD ) with special media
Bio Tower with special media
Ozone oxidation cum disinfection system
Side stream Filtration of sewage though pressure filter for reuse
Reuse in the Gardening and Gray water recycling to toilets
With RO / FO water can be 95% reused including drinking purpose as done at SINGAPORE.
Different STP Technologies Available are
BOD Removal – Suspended Growth – Complete Mix-Activated Sludge Process / Oxidation Ditch / Aerated Lagoons / Sequencing Batch Reactor (SBR)
Enhanced Biological Phosphorus Removal (EBPR) / Anaerobic/Anoxic/Oxic (A2/O)
Other Biological Processes – Attached Growth – Fluidized Bed Bioreactor (FBBR) MBBR / Fixed Bed Bioreactor IFAS / Trickling Filter (TF)/ Bio Tower
Anaerobic Processes – Expanded-Bed Reactor (Anaerobic Expanded Bed Reactor [AEBR]
Upflow Anaerobic Sludge Blanket (UASB)
Membrane Bioreactor (MBR) – Lowest Foot Print – Tubular, Hollow-Fiber, Spiral Wound, Plate and Frame Plate type found most efficient and reliable.
Our expertise helps you to upgrade existing plant bringing required results and increase capacity without new construction.
