Using a phosphorus coagulant can improve wastewater UV disinfection performance

After switching to ClariPhos™ rare earth coagulant to evaluate its ability to improve phosphorus removal, operators at an Ontario WWTP noticed that UV disinfection also experienced a big boost. It turns out that better settling in the clarifier led to higher UV transmittance in the effluent, and a significant improvement in UV disinfection.

Cleaning industrial wastewater collection systems requires specialized equipment

The task of industrial pipe cleaning typically falls to third party cleaning companies, who come to facilities with a vacuum truck and perform the work periodically, unless emergency debris removal is required. Industrial plants cannot afford production downtime, so contractors rely on high-performance nozzles to get the job done quickly and reliably. Using the right nozzle and technique can be the difference between cleaning out a pipe within 20 minutes or having it take hours, days, or even fail completely.

Choosing the right heat exchanger for wastewater applications

The challenging nature of wastewater and sludge, such as its high viscosity and high fouling potential, means that it is important to choose the right type of heat exchanger to reduce costs, maximize energy efficiency, and maintain heat exchanger operational performance.

Using an early oil spill influent warning system can prevent WWTP fouling

Although treatment plants are meant to handle all sorts of wastewater, incoming oil contamination still poses a considerable threat to a facility’s operations. These oil spill incidents can occur any time and without warning. If not handled properly, they can lead to contaminated wastewater flowing into natural environments.

Pumping long chain polymers in wastewater applications without damaging them

Flocculant and coagulation polymers are used in the removal of solid particles. Flocculants separate solid content in the wastewater from the liquid content. A coagulant combines small particles to form larger chain particles. These polymers change the charge of the particles, so that they will combine rather than repel other particles.

Alberta hamlet conducts bioaugmentation optimization study for wastewater lagoons

Treating a lagoon with Waste Go bioaugmentation can restore its health, mitigate costs, and postpone dredging for lengthy periods of time. However, eventually, even the healthiest of wastewater lagoons will require dredging as their capacity for biodegraded sludge will be reached. Sludge that has been properly treated with Waste Go will meet or exceed all environmental standards, thus making it readily available for disposal without further treatment or penalties, saving the treatment facility substantial costs.

rotary lobe pumps

Rotary lobe pumps help solve difficult biosolids pumping application requirements

Operations staff at one wastewater treatment plant were initially using a reciprocating pump to move raw sludge and biosolids from primary clarifiers to the anaerobic digesters. The percentage of solids was approximately 4% by volume and, in some cases, could get as high as 6% by volume. Due to the lack of a screen, the size of the solids could not be controlled, which often caused the pump to jam.
