    Oxygen monitoring from aerobic and anaerobic for toxicity test

    Toxicity of pure chemicals is assessed using respirometers by adding increasing concentrations to an active culture. The concentration at which oxygen uptake or gas production begins to decrease is known as the “threshold toxicant concentration.”

  • Waste water respirometry solutions for toxicity based consents

    Water companies, water authorities or publicly-owned treatment works (POTW) need to have some knowledge of the composition of the wastes they it receive. In addition to testing for ammonia and BOD or COD levels, treatment works can license industrial discharges on the basis of concentrations of some of the known toxic compounds. However, it is recognised that very many non-regulated toxic materials still enter the treatment works and reduce the efficiency of biodegradation, and may cause toxic shock. The way is...

  • Waste water respirometry solutions for toxicity testing

    If industrial wastewater entering a treatment works contains toxic components the rate of biodegradation will be inhibited or stop completely. This can result in failed consents and will certainly give rise to operational problems. Visible indications include deflocculation, bulking and the appearance of filamentous bacteria. Sometimes, there are no visible effects. When the sludge bacteria are inhibited, there is the possibility of toxicity carryover in the effluent that is discharged to receiving waters. With...

  • Waste water respirometry solutions for toxicity reduction tests

    In industrial manufacturing companies, before a new process comes on-line, it is important to measure the toxicity of the effluent stream. This is especially the case for companies who treat their own waste. From the toxicity value (EC50) obtained, it may be a cost-effective solution to simply discharge the effluent to the treatment works at a slow and defined rate to minimise damage to the activated sludge. Following a period of acclimatisation it is often possible to increase feed rates to the plant and this...

  • Smoke generator device for leak testing & building envelope testing

    Smoke is the perfect medium for discovering where leaks are and how big they are! Filling a `leaky` building, ductwork, pipes, aircraft or containment area with smoke and ideally adding a small amount of pressure to the area being tested, will result in a visible discharge of smoke and, simply put, the greater the volume of smoke, the bigger the leak. After Concept developed a bespoke system for their aircraft testing requirements, a spokesperson for the RAF commented: `The use of smoke as a means by which to...

  • Smoke generator device for building envelope, energy studies & air tightness testing

    The air tightness or leakage rate of a building is the uncontrolled flow of air through holes, gaps and cracks in the fabric of a building, which may not be detectable simply by looking at the outside of the building. Filling a building or void with smoke and pressurising that volume, will result in a visible discharge of smoke from any problem areas. Smoke is the perfect medium for discovering where leaks are and how big they are! Filling a `leaky` building, ductwork, pipes, aircraft or containment area with...

  • Removal of organic compounds & toxity for wastewater treatment industry

    Federal and State regulatory agencies are increasingly requiring additional water quality testing and controls of the toxicity of discharges to receiving streams. Granular Activated Carbon (GAC) helps meet these pollution regulations. If organic chemicals have been identified as contributing to discharge toxicity, Calgon Carbon Corporation can work with facilities, and their engineering firms, to help meet stringent criteria associated with their NPDES permit. GAC can be employed as a cost-effective treatment for...
