The design of a utility’s ozone disinfection system often includes a method to minimize the production of regulated oxidation by-products that may form when ozone contacts the water. In regions where water contains a significant concentration of bromide ion (Br¯ ), ozone disinfection systems often minimize bromate (BrO3¯ ) formation by modifying the water chemistry through the addition of chloramines, acid, or other chemical additives.
The desert community of Scottsdale, Arizona had no natural surface water sources and a decreasing groundwater supply. Scottsdale had historically treated and disposed of its wastewater.
Ultrafiltration (UF) membranes have already gained worldwide acceptance in the treatment of drinking water for their removal of chlorine resistant pathogens such as cryptosporidium. Tertiary treatment with UF has been established, although with a lower level of knowledge and number of installations. This paper will discuss the performance of hollow fiber UF/MF membrane modules in treating tertiary effluent, and the subsequent performance of the downstream RO membranes.
Due to their critical role in protecting the health of customers, drinking water treatment systems require a high degree of care and oversight.
When the Cobb County-Marietta Water Authority (CCMWA) anticipated the need to upgrade the Hugh A. Wyckoff water treatment plant, they turned to granular activated carbon (GAC) technology after vetting several alternatives. The plant, a wholesaler in a two-plant system, processes up to 72 million gallons per day and serves about 350,000 people. Comprising of Wyckoff and the James E. Quarles treatment plant, CCMWA is the second largest water provider in Georgia.

Keeping the water in our lakes, rivers, and streams clean requires monitoring of water quality at many points as it gradually makes its way from its source to our oceans. Over the years ever increasing environmental concerns and regulations have heightened the need for increased diligence and tighter restrictions on wastewater quality.
A North Carolina-based specialty chemical manufacturer, a major producer of insect repellent, was looking for a better way to measure the liquid level in its glass-lined agitated reactor. The company uses a number of complex technologies to manufacture sebacates, adipates, isophthalates, catalysts, alkyds, and other natural and renewable chemistries based on castor and citrates.
Energy costs continue to increase. At the same time, there is increased pressure to reduce utility bills without sacrificing operations or comfort.
Determining trihalomethane levels using standard analytical methods requires expensive equipment and highly qualified personnel, which also means that analysis costs are very high. For these reasons, trihalomethane analysis poses a serious problem for companies that supply drinking water. Read the full application note to learn how two drinking water laboratories improved quality control of water delivered to end users.
Years ago, high purity water was used only in limited applications. Today, deionized (Dl) water has become an essential ingredient in hundreds of applications including: medical, laboratory, pharmaceutical, cosmetics, electronics manufacturing, food processing, plating, countless industrial processes, and even the final rinse at the local car wash.
IMS’s custom-designed, modular LAS Feed Systems for water processes are pre-assembled, factory-piped, wired and tested, offering low installation costs and typical installation time of only 2 hours.
The MARINER OMNIPURE® series of Marine Sanitation Devices offer a fresh approach to sewage treatment in the workboat vessel market. With treatment capacities of up to 60 persons (black water) and up to 25 persons (black and gray), the largest unit treats 1,796 gallons (6,800 Liters) of human wastewater per day. The USCG Certified Type II MARINER OMNIPURE units incorporate the same electrolytic treatment benefits of any other OMNIPURE unit, but with the added advantages of less maintenance and a small, compact size to fit vessels in the workboat vessel market.
The revolutionary new ClorTec® SCT is a fully integrated patent pending design from De Nora Water Technologies. Salt, water and electricity are electrolyzed to produce up to 4.4 lb/day (2 kg/day) chlorine equivalent of hypochlorite solution at 0.7% strength. The system offers superior health and safety benefits for employees on site due to its innovative design.
Liqui-Cel MM Series products can save the time and expense associated with inaccurate analyser readings in laboratories and testing facilities by removing dissolved gases from water and other fluids. By removing air, these devices also prevent bubble formation which can potentially alter to composition of the solution be analysed.
Reverse osmosis, or RO, is one of the finest technologies to purify water containing high total dissolved solids (TDS) levels of more than 500 ppm. Reverse osmosis plant exporters explain the technology as a separation technology where dissolved and invisible impurities in water are separated with the help of semi-permeable membrane or RO membrane that works under high pressure.
Research from the UK has identified a “supermolecule” capable of seeking out and eliminating trace pharmaceuticals that contaminate water supplies.
The bigger water utilities have the resources, but small utilities face many of the same problems — namely failing pipeline infrastructure and water loss. So what are the solutions and best practices within small utilities’ grasp? One small utility shared its successful approach to controlling water loss as guidance for those with similar struggles.
With factors such as scarcity, aging infrastructure, and water quality driving the price of municipal water higher, businesses are increasingly considering other means of securing supply. This article examines the trend toward alternatively procured process water and its impact on municipal and commercial interests.

Drinking Water Treatment involves the removal of pathogens and other contaminants from source water in order to make it safe for humans to consume. Treatment of public drinking water is mandated by the Environmental Protection Agency (EPA) in the U.S. Common examples of contaminants that need to be treated and removed from water before it is considered potable are microorganisms, disinfectants, disinfection byproducts, inorganic chemicals, organic chemicals and radionuclides.
There are a variety of technologies and processes that can be used to decontaminate or treat water in a drinking water treatment plant before the clean water is pumped into the water distribution system for consumption.
The first stage in treating drinking water is often called pretreatment and involves screens to remove large debris and objects from the water supply. Aeration can also be used in the pretreatment phase. By mixing air and water, unwanted gases and minerals are removed and the water improves in color, taste and odor.
The second stage in the drinking water treatment process involves coagulation and flocculation. A coagulating agent is added to the water which causes suspended particles to stick together into clumps of material called floc. In sedimentation basins, the heavier floc separates from the water supply and sinks to form sludge, allowing the less turbid water to continue through the process.
During the filtration stage, smaller particles not removed by flocculation are removed from the treated water by running the water through a series of filters. Filter media can include sand, granulated carbon or manufactured membranes. Filtration using reverse osmosis membranes is a critical component of removing salt particles where desalination is being used to treat brackish water or seawater into drinking water.
Following filtration, the water is disinfected to kill or disable any microbes or viruses that could make the consumer sick. The most traditional disinfection method for treating drinking water uses chlorine or chloramines. However, new drinking water disinfection methods are constantly coming to market. Two disinfection methods that have been gaining traction use ozone and ultra-violet (UV) light to disinfect the water supply.
