  • 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.

  • Wilsa ElectroWaveTM Conditioning - Non-chemical water conditioning, break emulsions, enhance recovery

    Hudson Industries (a licensed partner) is now offering the patented Wilsa ElectroWaveTM Conditioner (EWC) for non-chemical water conditioning that provides enhanced oil recovery up to 99.999% with the power to break difficult emulsions. The Wilsa Effect is targeted at polar fluids, such as water. The Wilsa EWC directly targets the surface and interfacial tension of water molecules which breaks emulsions and forces the water to reject foreign matter such as oil and suspended solids. Furthermore viscosity is greatly reduced which allows the now coalesced oil to exit the water column with less friction, thus Stokes Law is fundamentally enhanced and retention time is greatly reduced. Combine the Wilsa EWC with your existing separation equipment or pair it with Hudson Coalescing Separator for maximum oil recovery/ removal. Contact us today for more information about Hudson Separators and Wilsa ElectroWaveTM Conditioning.
