Water and Wastewater Treatment Consulting
Original Poor Mixing Pattern
An industrial plant was using a combination of boiler stack gas and expensive carbon dioxide (CO2) to lower the pH of its recycled water, which needed to be neutral prior to use.
The company was adding stack gas at several points in the treatment train using simple coarse bubble diffusers in a clarifier center well and a subsequent pH adjustment tank. [Read more…]
Secondary Clarifier
Company leadership was concerned about the outcome of their large turnkey water and wastewater treatment plant project. The consultant they had hired to lead the project was not familiar with the client’s industry, process needs, safety standards, design requirements, or project management standards.
The client had limited budget and scarce engineering resources. They could not afford to make a mistake by allowing the turnkey consultant to proceed without proper guidance. [Read more…]
The wastewater generated by an industrial client was causing problems at the publicly owned treatment works (POTW) where it was being discharged.
Pump Station Foam
This water’s high concentration of surfactants and other organic chemicals was causing intensive foaming in the pump stations and plugging the air relief valves in the force main.
The client was going to be prohibited from discharging to the POTW unless it could pretreat the water to remove the surfactants, chemical oxygen demand (COD), and suspended solids. [Read more…]
