This paper presents a comprehensive overview of technologies for phosphorus removal and recovery, including chemical and biological processes, ballasted clarification, filtration, and nutrient recovery.
UV Treatment Upgrades In Wales

In order to improve the treatment performance (because of the continued cost to maintain compliance), and ensure that it would eventually have the treatment capacity to meet future population growth equivalent of up to 225,000, Swansea WwTW was in need of an equipment upgrade.
Before You Choose A Wastewater Treatment Technology, Ask These 5 Questions

When it comes to choosing a wastewater treatment strategy for a specific water issue, facility managers often start by asking themselves what the best technology is for addressing their contaminant. However, there are far more important questions that need to be answered first.
The Real Cost Of Wastewater Treatment: MBR Reshapes The Equation

For years, conventional activated sludge (CAS) has been the default in wastewater treatment. But the industry is changing.
Municipal Effluent Treatment In India

Discover how an agency balanced effective disinfection while minimizing environmental impact and ensuring the safety of both the public and workers in its wastewater treatment practices.
Strategies For Enhancing pH Control Systems In Wastewater Treatment

Managing pH in wastewater treatment is a crucial undertaking for water utilities. Solid contaminants often receive more attention, as they're more obvious threats, but sub-optimal pH levels can be dangerous, too.
Hot Water Disinfection For International Hotel Chain, Israel

See how an Israeli hotel chain slashed energy costs by 27% while ensuring Legionella compliance through innovative UV water disinfection technology.
Pasteurized Equivalent Water Treatment At High Desert Milk, Idaho, US

Learn how High Desert Milk, a cooperative in Idaho, optimized their water treatment process using HOD™ UV technology, ensuring FDA compliance while significantly reducing water and energy consumption.
Disinfection For Purified Water Loop For Kamada Pharmaceuticals, Israel

An Atlantium HOD™ (Hydro-Optic Disinfection) UV system was installed at the outlet of a PW tank to serve as the primary disinfection barrier, with water circulating through the system at 6m³/hr before reaching the points of use.
RO Membranes' Protection At Pinghu Power Plant, China

A power plant in Pinghu, Zhejiang Province in China needed to replace the use of chemical biocides and protect boiler feed make-up water from anaerobic and aerobic bacterial growth and associated biofouling.

GWT Specialized Electrocoagulation System
GWT electrocoagulation (EC) technology has become a valuable solution in the treatment of water and wastewater due to its ability to remove contaminants that are generally more difficult to remove by filtration or chemical treatment systems, such as emulsified oil, silica, total petroleum hydrocarbons, refractory organics, suspended solids, and heavy metals.
Foambuster
The patented Foambuster uses the same glass-lined ductile iron nozzles as Rotamix but also uses a stainless steel splashplate located below the nozzle to deflect the nozzle discharge and create a broad spray of sludge, which wets and breaks up foam forming on the surface of the digester. Digester sludge is pumped through the Foambuster either by the Rotamix Chopper Pump or by a separate Chopper Pump. When the Foambuster is used in conjunction with a tank mixing system, which produces a rotational mixing pattern in the tank, only one spray nozzle will be required for effective foam control.
GENCLEAN Muni
GENCLEAN™ Muni is an NSF 60 certified specialized advanced oxidation treatment solution for potable drinking water and domestic wastewater treatment plant facilities.
Disinfection
As the final step before treated wastewater leaves the plant, effective disinfection is extremely important to protect human health, and the maintenance of the environment. This process eliminates pathogenic organisms that cannot be removed by previous treatment steps and reduces the spread of pathogens in the natural ecosystem.

USP’s current offerings include our unrivaled in-house CFD modeling expertise that can be used to optimize the injection, mixing and feed rates of PAA to meet the disinfection requirements of a facility. Also, launching later this year, is our OaSys iCT™ is a novel control approach that optimizes disinfection performance by calculating the optimal chemical dosage that accounts for sources of treatment variability in real time. Available for use with PAA or chlorine.

Proven Approach To Tackling Aquatic Invasive Species

As aquatic invasive species continue to overwhelm hydropower, industrial, and municipal systems worldwide, this webinar explores why traditional filtration and chemicals are falling short—and how a dual-barrier UV approach is emerging as a proven, chemical-free alternative backed by global field results.

ABOUT WASTEWATER DISINFECTION

Wastewater disinfection takes place after primary, secondary and sometimes tertiary wastewater treatment. It is typically a final step to remove organisms from the treated water before the effluent is released back into the water system. Disinfection prevents the spread of waterborne diseases by reducing microbes and bacterial numbers to a regulated level.

A variety of physical and chemical methods are used to disinfect wastewater prior to it being released into natural waterways. Historically, the chemical agent of choice for municipal wastewater treatment has been chlorine, due to its disinfecting properties and low cost. However, the rising cost of chlorine and concerns that low chlorine concentrations can still be toxic to fish and other wildlife, has given rise to more physical methods of wastewater disinfection being adopted such as ozonation or ultraviolet (UV) light.

The use of ozone as a disinfection agent has the added benefit of increasing the dissolved oxygen content of the treated wastewater. However, because the ozone has to be generated, ozonation can require prohibitive up-front capital expenditure compared to traditional chlorination. UV disinfection has been growing in popularity as a wastewater disinfection method, in large part because of the life-cycle economics of the equipment and the fact that, like ozone, there is no toxic residual.
