Phosphorous Solutions For Wastewater Treatment

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.

ClorTec® Aftermarket Solutions And Services
De Nora Water Technologies can help you to optimise your electrochlorination system operation to deliver consistent life long performance.
NeoTech D328™
The NeoTech D328™ is specially designed to disinfect water and is an essential component in advanced oxidation processes.
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.
OaSys iCT™: Next-Level Dosage Control For Chemical Disinfection
When chemical disinfection is used, inherent variability in plant processes (e.g. flow events, plant upsets) can result in inadequate public health protection and risk of permit violation. To avoid these disruptions, WRRFs regularly overdose disinfectant, resulting in excessive cost for disinfectant and quenching chemicals and increasing sensitivity to chemical market conditions (supply disruptions, price increases).
Next Gen Capital Controls® Chlorinators
The unique compact design incorporates the best existing Capital Controls® technology with exciting new features. With just three models ranging from 10-10,000 lbs/day capacity, each chlorinator is available with automatic or manual feed and a 10” flowmeter for an easier read. Sonic operation on the 4100 model eliminates the need for a differential pressure regulator. On all automatic models, an additional controller isn’t needed, reducing components – and costs.

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.
