Domestic wastewater from toilets, showers, washroom and kitchen sinks, dishwashers, and washing machines together make up sewage wastewater. Treated at sewage treatment plants (STPs), this wastewater undergoes a series of stages to eliminate contaminants and reach safe parameters. Treated sewage effluent is typically used as irrigation water.
STPs focus on certain parameters during treatment: oil and grease, total suspended solids (TSS), chemical oxygen demand (COD), and biological oxygen demand (BOD5). Total dissolved solids (TDS) are not treated in conventional STPs, but certain technologies can be added to decrease it. In each treatment stage, sewage undergoes different kinds of processing that target specific parameters.
Blue offers specialized On-Site Treatment services that deliver water quality enhancement for domestic, commercial, and industrial wastewater effluents. Treatment modules are designed to meet effluent wastewater quality requirements, with partial and full-treatment alternatives that allow for water reuse on-site. They are installed above existing septic tanks or in-line with sewerage discharge line, with no/minimal civil works.
