Distribution Monitoring
Statement of the Problem Water systems are responsible not only for water quality at the end of the treatment process, but throughout the entire distribution system. This requires that treatment plants establish a disinfectant residual and maintain this residual throughout the distribution system. The Stage 1 Disinfectants and Disinfection Byproducts Rule (DBPR) applies to all […]
Processum aerationis compesce et energiam in processu aerationis conservare.
Statement of the Problem One major use of energy in a wastewater treatment facility is for operation of mechanical systems designed to introduce oxygen into the wastewater. This oxygen is necessary for biological treatment of carbonaceous matter (secondary treatment) and for oxidation of ammonia into nitrite and nitrate (nitrification). The transfer of oxygen can be […]
Treatment of food industry wastewater with high organic content
Statement of the Problem Several types of processes are currently in use for Biological Nutrient Removal, including processes designed to remove nitrogen and those designed to remove both nitrogen and phosphorus. Nitrogen removal processes employ successive nitrification and denitrification steps, which can be designed to occur at different intervals (such as in an SBR), in […]

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 […]
