Drinking water plants that use surface water or groundwater 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 plays a critical role…
In closed low-pressure water heating and cooling systems, sodium nitrite is a commonly used inhibitor that prevents oxygen related corrosion. It inhibits corrosion by promoting formation of protective films on surfaces. When nitrite is used as a corrosion inhibitor, it…
LOST PRODUCT = LOST REVENUE Manufacturers in the food and beverage industry lose significant quantities of product in the production process. In the dairy industry, milk losses are on average 2-3% of total production and can be even higher for…
Wastewater quality can change drastically and quickly – particularly in the case of industrial discharges – to generate shock loads within the wastewater treatment system. In addition to potential operational problems such as increased chemical and aeration demand, shock loading…
Although an effective treatment aid, residual permanganate in your treated water is undesirable and often leads to consumer complaints when pink water pours out of their tap. Careful control of permanganate dosing can be achieved with real-time permanganate monitoring, resulting…
Control of dissolved organics has been one of the highest priority concerns for most water treatment plants for over 20 years. Organics monitoring is an even more critical issue today in the face of more stringent regulations and concerns around trace organics,…
PARAMETERS TO MEASURE IN THE DISTRIBUTION SYSTEM Nitrite, nitrate, total chlorine, monochloramine, free chlorine, ammonia, TOC, pH, temperature OVERVIEW Nitrification events can be costly to remediate and harm your community’s trust in their water supply. Catching nitrification early and reliably lets you…
PARAMETERS TO MEASURE FOR NUTRIENT DOSING IN WASTEWATER BOD, COD, TOC, TSS OVERVIEW Nutrient dosing in wastewater must be carefully controlled to ensure a favorable nutrient ratio is achieved, resulting in good quality effluent. Real-time online monitoring of organic loading…
PARAMETERS TO MEASURE FOR AERATION OPTIMIZATION BOD, COD, TSS, DO OVERVIEW A significant portion of a wastewater treatment plant’s energy costs are due to aeration operations (~45-75% of the total energy). The required aeration rate of a biological treatment system…
The purpose of source water monitoring is to enable drinking water treatment facilities to identify changes in water quality, implement treatment strategies based on the characteristics of the water, optimize the treatment processes, and take preventative actions to protect the source water…
