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.

GDT Mixing & Contacting Systems
The GDT Process starts with the creation of ozone from an Ozone Generator. The ozone is then drawn into a Mazzei®Venturi Injector which provides dynamic mixing (a Back Pressure Control Valve adjusts injector outlet pressure optimizing ozone mass transfer in the system). Then mixing and contacting is enhanced in a Flash Reactor.
Capital Controls® Series 1041A Automatic Switchover
The Automatic Switchover system Series 1041 provides safe, reliable switching between two gas (pressure or vacuum) or two liquid (pressure or level) sources assuring an uninterrupted supply of chemical to the application. Automation of all functions (switchover, system initialization, configuration, lamp test, and safety functions) is done with an internal programmable logic controller for operational flexibility, enhanced reliability, and ease of use. If needed, local manual override is conveniently available for operator control to maintain continuous operation.
CHEM-FEED® Plastic Triplex Skid
CHEM-FEED® Engineered Skid Systems are now shipping! These Skid Systems are simple to operate, easy to order, and includes everything needed for precise chemical feed.
TOC Reduction
NeoTech Aqua Solutions provides the most efficient and cost-effective UV systems for destroying Total Organic Carbons (TOC’s) in water. Whether your destroying NDMA, 1,4-dioxane, TCE, MTBE, urea, endocrine disruptors or other organics, only NeoTech Aqua provides ultraviolet TOC reduction with a treatment chamber optimized for low pressure mercury lamps. As a result, NeoTech Aqua’s UV systems achieve a three times greater TOC reduction per kilowatt compared to standard UV systems, reducing our clients’ costs and energy consumption. In addition to efficiently generating ample 185 nm UV for TOC reduction, NeoTech Aqua’s TOC reduction systems also generate significant levels of 254 nm UV which serve as a powerful disinfectant, providing you both TOC-free and organism-free product water.
3-Way Valve
The 3-Way Valve is available in 4”, 6” and 8” sizes and is available as a stand-alone valve or as part of a Vaughan submersible or vertical wet-well Chopper Pump. The valve is a non-plug design using a rotatable CD-4MCu valve disc to allow discharge out of either of the top ports.

How Ozone Works In Water Treatment — Explained By A Chemical Engineer

This Pinnacle Academy session delivers a clear, practical, and technically informed exploration of ozone in water and wastewater treatment. The presentation walks viewers through ozone’s molecular properties, production methods, and behavior in water, highlighting why it is a powerful, fast-acting, and residue-free oxidant.

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.
