VACOMASS® Valve optimized for Air blowing system in wastewater treatment
VACOMASS® Biology securely under control When the biological stage of a sewage plant is undersupplied with oxygen, this will lead to process disruptions and consequently, the legally required limits for the effluent quality can be exceeded. However, if toomuch activation air is supplied, a significant increase energy is consumed, resulting in uneconomical operation of the […]
Cooling water analysis(Closed Loop)
Background Protection of closed loop recirculating water systems usually requires high pH and high levels of corrosion inhibitors. The pH range of operation generally limits the choice of corrosion inhibitors to chromate, nitrite, molybdate, hydrazine and certain organic polymers. Chromate concentrations are frequently carried at 200 ppm and higher. Nitrite formulations are often carried at […]
Chemical testing during water treatment
Background Wastewater can contain substantial inorganic phosphorous resulting from synthetic detergents, industrial processes, and high phosphate raw water. Industrial wastewater may contain a variety of phosphate compounds. (Some industrial waste may not contain sufficient phosphorous to promote the growth of the organisms used in wastewater treatment. See the application summary entitled “Nutrient Balancing” for a […]
Chemical phosphorus removal in water treatment
Summary: The text discusses the presence of inorganic phosphorus in wastewater due to synthetic detergent, industrial processes, and raw water with high phosphate levels. Industrial wastewater can contain various phosphate compounds. Polyphosphate undergoes gradual hydrolysis in wastewater, reverting to orthophosphate. This transformation is influenced by pH, temperature, and the presence of bacterial enzymes. Many wastewater […]
Electroless Plating
Statement of the Problem Plating and surface finishing processes often require the addition of chemicals (other than the object metal) into the plating or finishing solution. These additives are designed to improve the quality of the process or to impart a specific characteristic to the finished product. Unlike the concentration of an electro-deposited metal, which […]
Chloramination Control
Statement of the Problem Chloramination of water is performed to produce a more stable disinfectant compared to free chlorine. Chloramine has been shown to reduce the formation of THM and other disinfection by-products by as much as 80% while reducing certain taste and odor problems. In some parts of the US, especially the Midwest and […]
