EPR waste minimisation monitoring for wastewater treatment industry - Water and Wastewater - Water Treatment
The legislation also qualifies which parameters should be used for different type of industrial discharge. Determinants are specified for both laboratory and on-line continuous measurement. The Food and Beverage sector will be one of the first to implement the legislation. Currently parameters such as BOD and COD are used to regulate discharges. Although legislation has maintained these measurements for discrete water analysis, the importance of continuous measurement has now been recognised and TOC has been identified as an important on-line parameter. To give operators the confidence to choice instrumentation that is fit for purpose the Agency has introduced a product evaluation scheme referred too as MCERTS. Qualifying instrumentation needs to meet rigorous laboratory and field testing to qualify and the manufacturing process must also meet stringent criteria. The use of MCERTS approved instrumentation will assist the Operator to score the best possible score under the OMA-3 assessment.
Industry has already taken positive steps towards meeting the former IPPC regulations now the Environmental Permitting Regulations. Many have witnessed how such installations can produce dramatic financial and environmental benefit. Real time monitoring can identify faulty valve sequencing and allow containment of high strength effluent which left undetected, can detrimentally affect trade discharge.
The PROTOC TOC analyser has been successfully installed within the Brewing, Drinks and Dairy industries to monitor and control high strength effluent and reduce the cost of trade discharge. The Protoc 300 model has been assessed and certified under the MCERTS scheme providing additional confidence to the end user. Instrumentation such as pH and Turbidity meters have also been used to improve process control and minimise waste.
Chemical and energy reduction have recently been identified as key areas where increased efficiency may be realised. Effective coagulation control via feed back control mechanisms can reduce chemical use and associated costs. Similarly, the use of direct monitoring for ammonium within aerobic treatment can compliment existing DO measurement. Controlling aeration as a function of load has clearly demonstrated to be more effective, resulting in significant energy reductions, typically of 20-30%.
