Sequential Batch Reactor (SBR)
1. General Description
SBR (Sequential Batch Reactor) is an activated sludge wastewater treatment system that removes dissolved and suspended organic materials and nutrients. It combines aeration, settling, and decanting processes sequentially in a single reactor.
2. Process
- Aeration Phase: Wastewater is intermittently aerated in the reactor, allowing de-nitrification.
- Settling Phase: Feeding, aeration, and mixing stop, causing sludge to settle and separate.
- Decanting Phase: A controlled device separates the treated effluent from the medium.
- Selector Tank: A preceding tank applies a peak load to stimulate aerobic biomass for improved flocculation.
- The system operates on a PLC-based control mechanism.
3. Area Requirement
A 200 KLD SBR plant requires 170 m² for a depth of 3.5 m.
4. Power Requirement
For a 200 KLD plant running 22 hours daily, the power requirement is 279 kW/day.
5. Suitability
- Cost-effective and simple to operate.
- Ideal for upgrading existing plants and organic waste applications.
- Treated effluent is suitable for landscaping and toilet flushing.
Submerged Aerated Fixed Film Reactor (SAFF)
1. General Description
The SAFF (Submerged Aerated Fixed Film) system is an aerobic wastewater treatment process that combines attached fixed-film and suspended-growth systems.
2. Process
-
BOD Reduction: Uses support media to retain active biomass for reducing influent BOD levels.
-
Air Dispersal: Tubular diffusers with SAFF media ensure effective air dispersal and minimal blockage from biological film growth.
-
Improved Technology: More robust and compact than traditional Extended Aeration or Activated Sludge systems, with a fully enclosed design.
-
Ease of Operation: Rugged, simple to operate, and pre-assembled for quick installation.
3. Area Requirement
A 200 KLD SAFF plant requires 160 m² with a depth of 4 m.
4. Power Requirement
For a 200 KLD plant operating 22 hours daily, the power requirement is 310 kW/day.
5.Suitability
-
Cost-effective and engineered for efficiency.
-
Ideal for outdoor domestic sewage plants, with effluent suitable for landscaping and cooling towers.
-
Replaces Activated Sludge Processes (ASPs) for lower civil and operating costs, reduced reliance on skilled control, and better handling of power failures or operational lapses.
Fluidized Bed Bio Reactor (FBBR)
1. General Description
The FBBR (Fluidized Bed Bio Reactor) system is a hybrid process combining attached growth and suspended growth treatment methods.
2. Process
- Pre-Treatment: Raw sewage passes through a bar screen chamber into a below-ground collection sump, homogenized using a Coarse Bubble diffusion system.
- Primary Treatment: Effluent is pumped to the FBBR system for organic pollutant reduction.
- Secondary Treatment: The sludge-water mixture flows to a secondary settling tank, where sludge settles, and clear supernatant overflows into a clarified water tank.
- Disinfection: Hypochlorite solution is added for disinfection.
- Tertiary Treatment: Treated water passes through a pressure sand filter to reduce suspended solids, followed by an activated carbon filter for fine polishing.
3. Area Requirement
A 200 KLD FBBR plant requires 150 m² with a depth of 4.5 m.
4. Power Requirement
For a 200 KLD plant operating 22 hours daily, the power requirement is 276 kW/day.
5. Suitability
- Compact design, suitable for below-ground installations.
- Treated effluent can be reused for landscaping and cooling towers.
Membrane Bio Reactor (MBR)
