WeDoTanks - Equalization Tanks for Wastewater Treatment Plants
Flow equalization is one of the most effective management procedures for wastewater treatment plants. Steady state conditions are created when the influent flow is equalized over a defined period of time. With equalization, you can provide a more uniform effluent to biological treatment processes, especially in the popular BNR (Biological Nutrient Removal) processes. The equalization tank(s) must be sized to absorb and even out the peak flows coming from the collection system.
Generally, equalization tanks for wastewater treatment plants refer to a holding tank that allows for flow to be equalized over a specific period of time.
www.wedotanks.com®’s precast concrete equalization tanks are known for their dependability and long design life.
www.wedotanks.com® helps their clients get the right equalization system by offering one of the broadest arrays of custom specifications in the industry.
Items we can include in an Equalization Tank:
- Aeration Systems
- Decanting facilities
- Flow boxes to equalize flow over a 24 hour period of time
- Covered or open
- Plain concrete walls or decorative finish
- Or unique ‘Positive Odor Control System”
Equalization + Steady State conditions = Improved Effluent + Reduction in operating $osts.
Advantages of Equalization are many, below are just a few:
- Ability to control ph for better process control;
- Minimize chemical usage;
- BOD/COD, TSS, Alkalinity, Ammonia and TKN are equalized for better process control;
- No need to design for large peak flows, the EQ tank equalizes the flow and spreads out the peaks.
- Especially in BNR plants, control the DO to first stage anaerobic reactor.
