Too much of a good thing can create new problems as quickly as it resolves old ones. Maintaining a proper balance of antifoaming agents and polymer additives is critical for sustaining the appropriate air bubble size and distribution needed to achieve dissolved oxygen (DO) requirements for neutralizing high biochemical oxygen demand (BOD) in many industrial and food processing wastewater applications.
In treating water for the production of pharmaceuticals, the concentration of gases dissolved in the water plays an important role.
Chemical, petrochemical, and oil-refining plants are process-intensive operations with regulatory requirements to protect the surrounding water and air from the effects of industrial pollution. These external demands are matched by equally compelling internal pressures to address product purification needs, find alternatives to utilizing costly fresh water in production processes, reduce the carbon footprint, and operate efficiently and profitably.

In the sugar and bioethanol industries, robustness and reliability of the equipment are of paramount importance. The XFP pumps were taken into operation in 2013 and have been running continuously since then, without any interruption or specific maintenance.
While some water quality parameters may get more attention in industrial settings, few are more critical than conductivity. Understanding conductivity monitoring for industrial applications — where it is needed, how it works, and how to leverage the appropriate instruments and standards in order to pinpoint it — will unlock huge gains in efficiency, effectiveness, and regulatory compliance.
A milk producer operates an evaporated milk production facility that generates an average of 58,000 gpd of contaminated water with spikes of 1,200 gallons up to 12 times per day. Two 2,000 gallon batch tanks are used for pH adjustment before discharge. Most of the flow goes through the tanks.

At Fluence, we have more than 30 years of experience in the design, construction, and operation of waste-to-energy plants for a wide range of industrial and municipal clients. Our proprietary anaerobic treatment technologies process wastewater and sludge to produce biogas, which can be used to produce electricity and thermal energy, or which can be purified to produce biomethane for injection into the grid.
L'eau Claire upflow filters offer an alternative to conventional water clarifiers for removing suspended solids and colloidal material such as silica. Despite the influent loading, this cost-effective filtration process removes 98% of particulates ≥2 microns without the use of clarifiers, flocculation, sedimentation, dry chemical addition or mixers. Watch the video to see how it works.
A hospital had been pumping their wastewater with a submersible pump for years. But after seeing the benefits of the S&L Above Grade Wet Well Mounted Pump Station, they quickly saw the benefits - easier and safer maintenance, higher efficiency, long pump life, and more. Hear from the operator himself to learn why the hospital now prefers S&L's EVERLAST™ Wet Well Mounted Pump Station.
Many food processing facilities operating today were designed and built to accommodate consumer habits of a bygone era. As those commercial markets have evolved, and industry has adapted to the changes, the wastewater plants at those sites are no longer capable of processing the waste generated during production.
