Drinking water solutions for the source water monitoring/ protection - TOC, Algae, UV254 - Water and Wastewater - Drinking Water
Problem: A challenging aspect of drinking water treatment is often predicting or monitoring the changes that occur with incoming water quality. Seasonality, weather events, agricultural practices or upstream discharges can influence the quality of both ground and surface water over time. With multiple variables impacting source waters, monitoring historical trends may not be sufficient to predict raw water changes or detect uncharacteristic events.

Drinking water solutions for the coagulation optimization - TOC, UV254 - Water and Wastewater - Drinking Water
Problem: Drinking water plants that use surface water or ground water under the influence of surface water are susceptible to high levels of organic matter in the raw water. Reduction of organic matter through coagulation/sedimentation and filtration is important to lower the potential for disinfection by-product formation (DBP) and limit operational problems. In addition, organics in water consume the polymers used for the coagulation process, which reduces the efficiency of the treatment. Therefore, optimization ...

Drinking water solutions for the TOC removal efficiency - Monitoring and Testing - Water Monitoring and Testing
Problem: Organic matter (UV254/TOC) in drinking water can react with chlorine to form harmful disinfection by-products (DBPs). Some removal of TOC is achieved through the conventional drinking water treatment processes, while carbon absorption may be used to further enhance the removal of TOC prior to chlorine disinfection.

Drinking water solutions for the UV disinfection performance - UV Transmittance (UVT) - Water and Wastewater - Drinking Water
Problem: Waterborne pathogens can cause serious disease outbreaks. Drinking water disinfection forms the final barrier between these pathogens and humans. For drinking water disinfection, ultraviolet (UV) light has proven to be the best method for inactivation of Cryptosporidium parvum and Giardia lamblia parasites found in natural waters. Organic matter and suspended particles in water absorb and scatter UV light, interfering with pathogen inactivation by UV irradiation.

Drinking water solutions for the DBP formation potential - Water and Wastewater - Drinking Water
Problem: Drinking water plants that use chlorine for disinfection must ensure organic matter is removed before chlorination to limit the formation of harmful disinfection by-products (DBPs), most commonly Trihalomethanes (THMs) and Haloacetic acids (HAA5).

Wastewater solutions for wastewater UV disinfection performance - Water and Wastewater
Problem: Prior to environmental discharge, wastewater is disinfected to ensure pathogens present in the water are inactivated. Ultraviolet (UV) disinfection is becoming a widely accepted treatment technology for wastewater disinfection due to the deleterious effects of chlorine on aquatic life. The ability for the UV light to penetrate the water is directly related to the concentration of suspended particles and organic matter in water that absorb or scatter the light.

Wastewater solutions for ballast water treatment monitoring - UV Transmittance (UVT) - Water and Wastewater - Water Treatment
Problem: To operate safely and efficiently, cargo ships take in water to provide stability. This water, referred to as ballast, carries all kinds of bacteria, microbes and micro-algae. The ballast water must inevitably be discharged when the ship takes on cargo, often thousands of kilometers away from the port of origin, transferring pathogens and aquatic organisms that can cause serious environmental, economic and health problems.

Industrial solutions for process water control - Water and Wastewater
Problem: Water is fundamental for numerous manufacturing processes. Contaminated or poor quality process water can cause significant operational problems and compromise the quality of the product.

Industrial solutions for cooling water contamination - Water and Wastewater
Problem: Large quantities of water are used for cooling in industrial manufacturing. To prevent scaling, corrosion and biofilm in the cooling system, inhibitors and biocides are regularity dosed. Make-up water is continuously added to the system to balance the loss of water from evaporation. As water is added, the concentration of chemicals is diluted and the quality of water changes.

Industrial solutions for boiler feedwater impurities - Water and Wastewater
Problem: Poor water quality can result in significant operational problems and possible shut down of boiler systems. To limit the potential for scaling, deposition and corrosion, most boiler water is treated physically or chemically to remove impurities and improve efficiency in the system.
