Biological sewage treatment plant WETTTM-S

Terragon has developed the novel patented WETTTM-S for sewage, concentrated sewage, and industrial wastewater. While domestic and community situations usually produce typical municipal sewage, situations that have low per capita water usage or that have separate greywater (GW) and blackwater (BW) collection may generate highly concentrated wastewater. Such situations include: Ships and sea platforms Isolated habitats such as mining, research, exploratory and military camps Small communities which have a high cost for potable water Northern communities WETTTM-S has been trialed on a government vessel for BW and has been containerized for evaluation by the US Army for highly contaminated sewage generated by Forward Operating Bases. As with all WETTTM products, WETTTM-S is based on Terragon’s proprietary self-cleaning passivation-resistant EC unit as a first stage to remove approximately 75% of all contaminants. Sewage or BW still contains a high concentration of COD and BOD after this stage. Thus in WETTTM-S, EC is followed by electrochemical oxidation (EO) to destroy residual organics. EO is based on Boron Doped Diamond (BDD) electrodes, which are robust and able to produce highly reactive hydroxyl radicals. Once through the EC and EO, the treated BW is now fully disinfected and ready for discharge to the environment. WETTTM-S has a number of truly unique features which are not available with typical sewage treatment approaches: Entirely electrochemical No micro/ultra/nano filtration, no membranes! No biological treatment, no chemical addition Immediate treatment, on/off capability Reduces COD, BOD, TSS
