Problem: Loss of Wastewater Nitrification or Inadequate Nitrification Wastewater systems that are laden with ammonia nitrogen and have an ammonia nitrogen limit must have competent waste stream nitrification. Often times due to waste stream toxicity or inhibition, over-wasting of biomass (that contains the nitrifying bacteria), cold wastewater temperatures or over grazing by biomass micro-fauna, wastewater […]
Cold weather Nitrification Problem: As wastewater cools during cold weather, the metabolic rate of nitrifying bacteria slows down. Below 25 degrees Celsius, for every 5 degrees Celsius that the temperature drops in a wastewater environment the nitrification rate is cut in half. This wastewater temperature inhibition to nitrifying bacteria causes depletion of nitrification in numerous […]
Problem: Low rate anaerobic lagoons in the meat processing industry can have compromised performance issues due to an inadequate supply of essential trace metals. The essential anaerobic trace metals nickel, cobalt, molybdenum, manganese, copper, zinc, aluminum, and boron (to a lesser extent – selenium, vanadium, and tin) are essential in the growth and metabolism of […]
Surface Tension is an important component of anaerobic digesters and can be used for maintenance of biosolids in anaerobic processes. Anaerobic wastewater surface tensions can run from 30 dynes/cm up to 70 dynes/cm (tap water is around 72 dynes/cm). Surfactants, volatile fatty acids, alkalinity, oil and greases, and salt are known to impact surface tension […]

Problem: Quaternary ammonium compounds can negatively affect the performance of anaerobic and aerobic wastewater treatment. Quaternary ammonium compounds (Quats) are not broken down during anaerobic treatment. They inhibit anaerobic bacteria and Archaea leading to diminished BOD removal, reduced methane production and reduction in the production of anaerobic granules in high rate anaerobic wastewater systems. In […]
Problem – INSUFFICIENT GRANULE PRODUCTION AND LOSS OF ANAEROBIC GRANULES IN AN HIGH RATE ANAEROBIC TREATMENT SYSTEM: In high rate anaerobic wastewater treatment systems (UASB’s, EGSB’s etc.) the development of granular sludge is a key factor for successful operation of high rate anaerobic treatment systems. Criteria for determining if granular sludge has developed in a […]
Problem: – pH Swings in Flotation Systems Causing Inadequate Removal Capabilities Do you experience pH swings in your flotation system? Does this cause you to pH adjust up or down utilizing acid material and basic material in order to increase your removal rate? Most plants that have pH swings (some very large) will adjust to […]

Problem: PAA Toxicity to Anaerobic and Aerobic Wastewater The increased usage of per-acetic acid and peroxyacetic acid (PAA’s) is causing waste stream toxicity issues in food processing company’s wastewater treatment systems. The high concentrations of PAA hitting wastewater plants is causing poor performance in anaerobic lagoons and causing loss of nitrification, poor mixed liquor settling […]
