Using Ozone To Remove Micropollutants From Wastewater

‹ ›

The use of gaseous chlorine at water treatment plants has, for many years, been an effective method of disinfection. It is still the most commonly used disinfectant in plants throughout the United States.

An Alternative Mathematical Model For Oxygen Transfer Evaluation In Clean Water
Energy consumption from aeration system is a biggest part of the total energy cost in wastewater treatment plant and account for as much as 60% of the energy consumption for the activated sludge process. Therefore, it is very important to know how effective the aeration system and significant attention has been paid to development and upgrade of standard method for quantifying oxygen transfer efficiency of the aeration system.

Small UV Plant Is Designed To Address Cultural And Safe Drinking Water Needs Cost-Effectively
BI Pure Water worked with University of British Columbia researchers and Lytton First Nation to develop a water disinfection system that addresses the needs of native communities, both cultural values as well as the basic necessity of clean drinking water.
Engineering For Safe Chlorine Disinfection
For more than 75 years chlorine has been effectively used to disinfect drinking water, eliminating dangerous bacteria and toxic compounds. Water supply engineers and treatment facility operators are used to necessary risks and problems associated with chlorine disinfection in order to deliver safe water. By Harland R. Pond, Product Manager; Grundfos
The UV Uprising: How UV Disinfection Will Claw Its Way To Prominence
Chlorination in all of its forms — gas, liquid, or solid — has been the primary way for treatment plants to disinfect the treated wastewater. The treatment plants that use gas chlorination must face federal regulatory oversight in the form of a Risk Management Program (RMP). Liquid chlorine plants trade in the regulatory oversight for a more expensive and less effective product. While chlorine in its solid form is good for small treatment facilities known as package plants (named for their mobility). However, ultraviolet (UV) technology is rapidly altering the landscape of disinfection throughout the industry.
Generating Disinfectants From Water: Could In Situ Electrolytic Production Be The Future?
Chemical disinfection using strong oxidants involves the transportation, storage, and handling of unstable and/or aggressive and hazardous chemicals. The production of oxidants at the location where they are to be used has therefore been a preferred option, especially in small-scale or remote installations. On-site electrolysis of NaCl for the local production of chlorine or hypochlorite, or the production of ozone-enriched oxygen by silent discharge has been standard for years. However, it is possible to take the idea of producing chemical disinfectants locally a step further and look at in situ techniques, i.e. at devices, which produce oxidants in and from the water to be treated.

On-Site Disinfection Helps Ensure Safety At British Columbia Water Treatment Facility
Constructed in 1997, the District of Chetwynd Water Treatment Plant (British Columbia, Canada) treats nearly 2,500 cubic meters of water per day using gas chlorination as its primary form of drinking water disinfection
Why All The Hype About Chlorine Gas Safety?
Remember when “Little Old Lady” Clara Peller rolled up to the drive-through window of Big Bun and asked “Where’s the beef?” She was asking a literal question, but also making a figurative statement.
Color Reduction From RO Concentrate
The City of Palm Coast, FL was experiencing elevated color in the concentrate stream being directed to the lime softening facility to recover as drinking water. In an effort to meet secondary color standards at the lime plant, this water quality issue limited the volume of the concentrate able to be recovered.
GAC Solution For Ohio's Most Challenging Water
Over the course of many years the City of Celina, Ohio has been challenged with supplying drinking water to the 11,647 residents of the city and the East Jefferson District.
Disinfection Performance Testing Of High-Efficiency Ultraviolet Water Treatment Chamber
This is the second in a series of three white papers describing the design and performance of the NeoTech Aqua ReFlex™ treatment chamber. The first describes in detail the theoretical basis for the very high efficiency demonstrated by the chamber. The third paper describes how this chamber design leads to some highly desirable operational advantages beyond just energy ad cost reduction. By J. R. Cooper, Ph. D. and Gwynne Cavender, NeoTech Aqua Solutions, Inc.
The Basics Of Disinfection
From utility water to wastewater, whether used in industrial processes or for drinking, disinfection plays a prominent role in providing safe and useable water. Water free from pathogens and other microorganisms ensures processes run efficiently and people are kept safe from disease. By Harland R Pond, Business Development Manager – Water Treatment
UV Eliminates Cryptosporidium Issues In The Heartland
The City of Moline is now adding validated UV systems to provide an additional barrier for the filtered water, which will improve water quality and ensure that none of the chlorine tolerant organisms such as Cryptosporidium is present. The City of Moline is located in the heart of the Midwest, tucked between the banks of the Mississippi and Rock River in Rock Island. Moline is one of four cities that make up the Quad Cities that include Rock Island, Illinois and Bettendorf and Davenport Iowa.
