Biological Nutrient Removal is allowing many wastewater treatment plants to achieve extremely high effluent quality. Still, for some applications even the most advanced BNR processes can’t address all concerns.

Greenwood Lakes Water Reclamation Facility, located in Seminole County, Florida- just north of Orlando, treats approximately 694 million gallons of wastewater each year.

After decades in service, the wet well at the Laguna Southwest Orange County Wastewater Authority (SOCWA) lift station became dilapidated. The project included a hybrid manhole/junction structure that would also serve as the bypass wet well during the rehabilitation work. Upon completion of the wet well rehabilitation, the temporary sewage bypass pumping system was removed and normal lift station operation was restored.

The AquaNereda® Aerobic Granular Sludge System (AGS) is an innovative biological wastewater treatment technology that provides advanced treatment using the unique features of aerobic granular biomass. This advanced nutrient removal process can reduce footprint up to 75% and energy up to 50% when compared to conventional activated sludge systems.

The Toray MBR modules helped a local utility achieve their goals of conserving water and meeting the Regional Water Quality Control Board's effluent standards (Title 22), so the reclaimed water can be used for irrigation and other reuse applications. 

A refinery needed to upgrade the wastewater treatment system to prepare for expected changes brought about by the use of a new crude feedstock with elevated concentrations of TDS and conductivity. Veolia Water Technologies supplied an AnoxKaldnes Moving Bed Biofilm Reactor (MBBR) treatment system to reduce the BOD and ammonia in the effluent.

As electronic measurement, microprocessor or computerized control, and wireless networking have worked their way deeper into industrial processes, new opportunities for accuracy, convenience, and cost-saving efficiency have multiplied. Electronic accuracy and communication have delivered performance advantages down to even the simplest functions — including pressure readings.

Until 2012, the Kaufman, TX, Wastewater Treatment Plant (WWTP) operated two separate aeration basins with mechanical surface aerators. As the plant’s equipment aged and required more frequent and expensive repairs and maintenance, the City of Kaufman followed its engineering firm’s recommendation to install a new, more efficient, fine bubble-diffused air system rather than simply replacing its old mixers with in-kind equipment.

Looking to reduce its water footprint, Shepherd Neame Brewery invested in a complete membrane bioreactor (MBR) wastewater recovery and re-use plant. Learn how the new plant's aeration system has helped to reduce the brewery's water-to-beer ratio to an industry-leading value of 3:1.

A retreat and camp facility struggling with variable flow conditions and associated wastewater issues turns to a fixed-film treatment system designed just for that application. The results have far exceeded expectations: treatment quality surpasses permit levels and regular operation and maintenance requirements are at an all-time low.

Despite their importance in modern wastewater applications, not all DAFs are created equal. Factors, such as the components that make up these systems, will influence how well they work and how long they last.

This application note will explore installations of AquaSBR Systems worldwide in a variety of municipal and industrial applications. 

Any process plant constantly generates a high volume of status data. Today, this data can be extracted from the plant, stored, analyzed, and prepared to meet operator needs and lower marginal costs.

Homes, industry, schools, and businesses all generate sanitary waste, or sewage. Sewage treatment is a multistage process that cleans up wastewater before discharge or reuse. In the final step of the treatment, disinfectants are added to kill disease-causing organisms. Common disinfectants are chlorine gas and sodium hypochlorite. Chlorine dosage levels are designed to leave almost no residual in the wastewater after treatment

QuEChERS is a Quick-Easy-Cheap-Effective-Rugged-Safe extraction method that has been developed for the determination of pesticide residues in agricultural commodities.

This application note explores how Greenline pumps enhance odor control systems by delivering precise chemical dosing for odor mitigation and pH control, ensuring cleaner air and improved quality of life.  

The need for of nitrogen-reducing wastewater treatment systems has become more common in the past few decades due to various environmental concerns, including eutrophication, oxygen depletion, and toxicity to aquatic organisms in lakes and streams. The addition of nitrogen removal to any wastewater treatment plant, new or existing, typically increases the costs of the project significantly. When evaluating suitable technologies, it becomes critical to properly identify processes that can not only proved the best upfront capital value but also provide the most sustainable long-term functionality.

Solids present in wastewater need to be safely and comprehensively treated and removed. This means not only removing toxic compounds, including both organic and inorganic materials such as heavy metals, but also eliminating any harmful bacteria present in the solids.

Stockholm water company produces biogas from their wastewater facility which feeds Scandinavian Biogas for energy production. As they need to accurately meter what they sell to the energy facility they used a project contractor firm to engineer and define the best solution for the project.
