CST Wastewater Solutions’ advanced MBR (membrane biological reactor) wastewater treatment system, the Titan MBR, is a low-maintenance system for municipal and industrial applications. The pre-engineered Titan MBR wastewater treatment system merges the wastewater treatment engineering of Smith & Loveless with submerged flat-plate membrane technology that ensures high permeability and flux rates.
According to CST Wastewater Solutions, this combination yields a dynamic MBR wastewater treatment system that provides end-users with quality treatment performance, minimal operational requirements and a robust design.
Titan MBR wastewater treatment system’s flat-plate membrane design results in less wear and tear and can easily be cleaned in place. Air scouring prevents fouling and eliminates the need for back-pulsing pumping equipment.
Pressure created by gravity drives the flow through the membranes. Clean water discharges into a clearwell, while blocked solids remain suspended in the aeration zone. Diffusers beneath the module scour the membranes while also providing an air supply to the bacteria.
Titan MBR wastewater treatment system provides long-term durability, according to CST Wastewater Solutions. The membrane is composed of PVDF (polyvinylidene fluoride) and non-woven polyester fabric. Vertical membrane surfaces do not touch each other during operation. The design prevents breakage experienced in other designs and produces higher flux rates over time.
The Titan MBR wastewater treatment system’s membranes eliminate clogging problems experienced in hollow-fibre designs. Their smooth, continuous surfaces prevent the build up of solids that result from hollow fibres being bundled by stringy solids such as hair. The flat surfaces also facilitate air scouring in the aeration zone effectively.
The membranes maintain high permeability and flux rates at peak-day rates. They stack within a fully submerged module inside the aeration zone. Chemical cleaning occurs efficiently in place on a semi-annual basis with chemical injection. Flat-plate membranes use less chemicals and equipment.
The Titan MBR wastewater treatment system provides effluent quality of < 3 mg/L BOD and < 1 mg/L TSS. Turbidity is < 2 NTU. TKN is < 2 mg/L and NH3 is < 1 mg/L.
