A textile biological treatment system needed to upgrade the performance of their existing wastewater treatment system. They wanted to reuse the majority of their wastewater. This created the need for a robust system that will produce purified water for reuse. Dynatec was selected to provide the ultrafiltration (UF) components of the MBR. Out-of-basin membranes were the ideal choice.
Membranes consistently produce high-quality effluent. The presence of pigments were problematic for other alternatives. The Dynatec MBR UF system was pilot tested and demonstrated consistent performance providing the high-quality permeate required.
The MBR effluent, now free of suspended solids and most of the organic load, is then processed through a RO system for further purification. The Dynatec MBR system, using tubular out-of-basin membranes, permits operation at high MLSS and produces lower chemical oxygen demand (COD) results thereby reducing the organic fouling at the downstream RO system.
The system capacity more than doubled employing existing aeration tanks with an upgrade to the aeration. Qualitative treatment results also improved. The project cost was less than the cost to expand the plant as a conventional biological plant with the addition of another bioreactor and clarifier.
Textile biological treatment system
Textile wastewater treatment systems have been provided by Dynatec Systems for numerous facilities. The treatment method chosen depends greatly on the specific characteristics of a plant’s wastewater and the discharge requirements or wastewater reuse applications within the plant.
