  • Wastewater Recycling

    TIGG’s activated carbon wastewater systems allow industry to meet environmental effluent requirements and discharge directly to POTWs or permitted surface waters. In some cases TIGG’s systems are used to recycle wastewater for non potable water applications to lessen demand on local water resources.

    Measuring Fats, Oil and Grease (FOG) in Wastewater

    It is estimated that 23-28% of Sanitary Sewer Overflows (SSOs) are due to Fats, Oil and Grease (FOG). With significant growth in the commercial food sector on top of other high FOG producing industries such as metal processors, meat packers, cosmetic manufacturers and industrial laundry establishments, the need for publicly owned treatment plants (POTWs) and industries to regulate and monitor FOG is crucial to public health. Besides clogged sewer lines, high FOG levels also disrupt the effective operation of a wastewater treatment plant. An important feature of any FOG program is locating and monitoring high oil and grease producing industries and food service establishments. InfraCal TOG/TPH Analyzers provide a simplified procedure for FOG analysis based on solvent extraction and infrared absorption which can give the regulator or operator an on-site result in less than 10 minutes.

  • 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 now open for more widespread use of direct toxicity tests as a basis for toxicity-based consents. Samples of the industrial effluent are collected at source, for testing on the actual bacteria of the receiving activated sludge. The tests used are the Respiration Inhibition Test and the Nitrification Inhibition Test. Note that this approach mirrors that of the regulators of discharges to receiving waters, who are now using direct toxicity tests (DTA) or whole effluent toxicity tests (WET tests) in order to protect the receiving environment.
