Level, turbidity analyzer
The BinMinder 9300-ETS from Entech Design combines ultrasonic sludge level and 90º scattered light turbidity in a dual purpose analyzer. Until now, operators have had to rely on visual inspection, time-delayed lab analysis, or turbidity measurement in combined discharge channels to monitor effluent water quality.

Oil, grease monitoring
Wilks Enterprise has developed a portable infrared instrument, the InfracCal™ TOG/TPH Analyzer, Model HATR-T2, that uses hexane to extract oil and grease from effluent samples. In the new effluent limitation guidelines governing oily waste discharges, EPA lists oil and grease as "hexane extractable material." Because hexane contains hydrocarbons, it must be evaporated off in order not to interfere with the infrared hydrocarbon measurement of oil and grease.
