EcoTec- Sequence Batch Reactor

EcoTec- Sequence Batch Reactor

In India, it is estimated that a person disposes 135- 150 litres of water per day. Each person discharges 60 grams of waste into the water when involved in activities such as flushing the toilet, urination, defecation, hand washing, cooking, washing clothes, etc. There is also water being used in kitchen for washing utensils and food preparation.  EcoTec sewage treatment systems, ESBR and EcoSBR treat household sewage wastewater. When treated, water can be sent to nature without harmful effects on environment and people. SBR process is reliable and is acknowledged by the Indian regulators and the Pollution control boards. SBR is considered as one of the few promising treatment systems for nutrient removal from sewage water.

Sequence Batch Reactor Process

denitrification, nutrient removal, charging, filling in wastewater treatment plant

1.Filling

Required quantity of sewage water from the collection tank is pumped into the aeration chamber also called  SBR chamber/reactor  for treatment. During this process air supply to the reactor is cut off so that there is no excessive oxygen available for micro-organisms. This creates an environment that favors the procreation of microorganisms with good settling characteristics. Aeration or denitrification follows this process.

2. Reaction

Air is supplied in a time sequenced manner until the required amount of pollutants are removed from the sewage water. Denitrification in the start of the reaction aids the biological nutrient (Amminia Nitrogen NH4, Nitrates, Nitrites) removal. BOD and COD reduction is achieved by activated sludge process where, pollutants are consumed by activated Sludge. The MLSS in a SBR reactor varies, while the duration of aeration determines the BOD and COD reduction.

3. Sedimentation

Activated sludge settles to the bottom when air supply is cut off, with a clear water zone appearing at the top. This clear water is ready to be taken out of the chamber. During sedimentation process, no aeration, filling or discharge can happen. The duration of sedimentation is determined by sludge settling properties, can vary from 30 minutes to up to 90 minutes.

4. Discharge

Most commonly know as decantation, clear water removal with low suspended solids is taken out of the SBR chamber for disposal, treatment for reuse and recycle. The settled sludge is removed for further storage and disposal. After this process the plant is ready for the next treatment cycle.

EcoTec- Your partner in treating wastewater

Retrofitting existing and non performing sewage Treatment!

Non performing sewage treatment plant- No problem- EcoTec has the answer - Head Ache free operation assured.

Most of the time the non performance of the plant could result from improper planning, inadequate design,  mismatched equipment, unreliable operator and underestimating sewage treatment process.

EcoTec has refurbished many such plants, upgraded manual plants to automated processes, and you can benefit from our expertise.

Batch Process takes care of varying load and flow conditions!

inconsistent flow and loading in STP is handled by EcoTec and performance is assured at all times.

EcoTec's EcoSBR and ESBR are activated sludge processes designed to operate under non-steady flow of wastewater into a treatment plant. SBR carries out the functions of aeration and sedimentation in a time sequenced manner with the ability to treat a wide range of sewage inflow volumes, whereas continuous systems work (MBBR, FBR, MBR) with fixed sewage flow rate. EcoTec plants eliminate the need for minimum loading required in convention sewage treatment process.
