Sewage Treatment Plants ( STP )

 
We Design, Fabricate, Supply, Erect and Commission Sewage Treatment Plants (STP) for treating sewage generated by Industry, large colonies, Hotels, Hospitals, IT Parks and commercial buildings.
Now a days the Sewage Treatment Plant (STP) became statutory requirement of all the State Pollution Control Boards, everybody, whether Hotelier or Industrialist were looking for economical, easy to install and operate compact type Sewage Treatment Plant. Since the land is extremely expensive, very few industries could afford the large treatment units as recommended by most of the Consultants.
We are being pioneer in the field from last 13 years and always in the search of latest and techno-commercially viable technology, system by which the need of the society can be easily satisfied.

With the large demand and future requirement we came with the Portable Package Sewage Treatment Plant concept. It’s a FRP coated MS fabricated unit can be easily transported to site which thus reduces the unnecessary civil cost, improves workmanship, speedy work and excellent treated water quality.
As per the clients need and suitability we offer very latest technologies like MBBR, FAB, SAFF, SBR and MBR.
 
Principle of Treatment :
 
Its working on the principle of Aerobic Treatment with the help of aerobic bacteria, which is most conventional and proven method throughout the world.
 
Treatment Steps :
 
Equalization and Pre-Aeration.
Bio-Reaction in the Aeration tank.
Sedimentation.
Filtration- Sand and Activated Charcoal
Chlorination
Sludge Drying and Disposal
 
We employed various treatment methodologies for SEWAGE treatment which are :
 
ASP- Activated Sludge Process
MBBR- Mixed Bed Bio Reactor
SBR- Sequential Batch reactor
CSTP- Combined(Effluent)Sewage Treatment Plant
SAFF- Submerged Aerobic Fixed Film
 
Mixed Bed Bio Reactor [MBBR]
 
Designing and supplying of MBBR or FAB are basically for sewage & industrial wastewater treatment. MBBR system is an advanced high rate wastewater treatment process utilizing free-floating media which houses huge quantity of active Biomass in it. Essentially MBBR system is a hybrid reactor where attached growth and suspended growth activity takes place simultaneously. Fine Bubble diffusers are used with the MBBR media in suspension (specific gravity < water) giving a good air dispersal and low level of blockage due to growth of biological film. The technology is rugged and simple to operate and the units can be pre-assembled for rapid on-site installation.

Principle :
 
The Mixed Bed Bio Reactor (MBBR) process it works on the principle of attached growth system and uses rotating biomedia to retain an active biomass to reduce the influent BOD Levels.
 
MBBR COMBINES :
 
1] MBBR Reactor To degrade organics
2] Tube Settler To separate the Biomass
3] Polishing Filters (Optional) Achieve absolute filtration.
 
Advantages over Conventional ASP :
 
The MBBR system is a great improvement over Conventional Extended Aeration or Activated Sludge Plants, and provides a robust and compact unit in a fully enclosed design.
No sludge re-circulation is required to maintain MLSS as in the case of conventional aeration system.
Can be designed to any size to deal with larger flow and loads. Around- 10 m3 to 1000 m3/day.
Fine bubble diffused aeration used generally reduces the energy requirements as compared to surface aerators.
The tank does not need to be drained for access to the diffusers or media.
MBBR system takes higher shock loads without reducing the plant performance because of large quantity of MLSS available inside the reactor.
FAB supports low sludge generation, low Adour and low Visual impact.
Maintenance requirements are simple.
 
Benefits :
 
Hydraulic Retention Time (HRT) of 4-6 hours vs 10 – 16 Hours.
Solids Retention Time (SRT) of 15-365 days, can vary based on flow without negative process impact.
Modular expandability.
Highest quality effluent.
Less susceptible to upsets due to flow variations.
Less odor.
Simple, yet sophisticated.
 
Sequential Batch Reactor [SBR] :
 
The Sequencing Batch Reactor (SBR) is an activated sludge process designed to operate under non-steady state conditions. An SBR operates in a true batch mode with aeration and sludge settlement both occurring in the same tank. The SBR design is a fill and draw type activated sludge process where individual reactors are filled one by one in five discrete periods i.e. Anoxic fill, React, Settle, Decant and Idle / Waste sludge. The SBR system can be designed with the ability to treat a wide range of influent volumes hence there is a degree of flexibility associated with working in a time rather than in a space Sequence.
 
 
SBR aeration system generally consists of fine bubble air diffusers. In this process, the compressed air is sheared into small bubbles creating large specific surface area for higher mass transfer efficiency between air and wastewater. SBR produce sludge with good settling properties provided the influent wastewater is admitted into the aeration in a controlled manner. An appropriately designed SBR process is a unique combination of equipment and software providing highest level of effluent quality on all parameters including BOD and Nutrient removal. Automated control minimizes the manual intervention and thus less possibility of operational errors.
 
Principle : SBR COMBINES
 
1] SBR Reactor / Aeration Tank To degrade organics Tube
2] Settler & Polishing Filters To separate the biomass Achieve absolute filtration.
 
SBR COMBINES
 
Advantages :
 
Better resistance to sludge bulking than other types of activated sludge systems.
No need for external clarifiers.
Easily adaptable to nutrient removal.
Greater system flexibility and control than other types of activated sludge systems.
Less land required and less processing equipment to maintain than other types of activated sludge systems.
Greater ability to meet effluent limitations (organic and nutrient) than other types of activated sludge waste/ Wastewater treatment systems.
Can retrofit existing tanks, basins, and ponds.
 
Benefits :
 
Low maintenance and user friendly design.
Eliminates all diffusers and associated network costs.
Dual-Function capability offers independent control of aeration and mixing modes for a wide degree of process control and flexibility.
Easy to integrate nitrification/ denitrification cycles and to facilitate biological phosphorus removal.
Eliminates the need for separate mixers.
Surface mounted allows for ease of inspection and maintenance.
Tested and proven controls package.
Eliminates final clarifiers and associated pumping.
Multi-reactor Batch and Single-reactor Continuous Flow designs available.
 
Submerged Aerobic Fixed Film [SAFF] :
 
The Submerged Aerobic Fixed Film (SAFF) process uses support media to retain an active biomass to reduce the influent BOD Levels. Tubular diffusers are used with the SAFF media giving a good air dispersal and low level of blockage due to growth of biological film.
SAFF reactor is a type of aerobic attached growth treatment process. Small foot print area, stable process, lesser sludge production and cellar installations are the key features of SAFF process. Essentially SAFF system is a hybrid reactor where attached growth and suspended growth activity takes place simultaneously.
This technology utilizes an aerobic fixed film process that is a combination submerged attached growth and activated sludge processes.

This plant proficiently drains out water from sewage and effluents and hence making it usable for other application such as gardening, farming and washing. Our range of combined sewage cum effluent treatment plants is available in standard specification and can also be customized to meet the varied requirements of our clients.
 
Combined Sewage Treatment Plants (CSTP)
 
Many times it is found that the treated Effluent from the ETP can’t be directly used for gardening because of non-compliance of certain parameters, in that case it is advisable to treat this effluent in the STP to get the desired limits under control.
