Buoyancy-Enhanced Membrane Filtration for Oilfield and Industrial Water Reuse

High-Quality Permeate We take a different approach on concentrating the Production Reduced Membrane way we use membranes for wastewater streams that Fouling would otherwise be considered non-reusable. BUOYANCY-ENHANCED MEMBRANE FILTRATION REVOLUTIONIZING how The Swirltex process manipulates the hydraulics of off-the-shelf industries utilize tubular ultrafiltration membranes to simultaneously: wastewater. Swirltex Tubular Membrane Filtration with Induced Annular Flow Step 1: Inject Micro-Gas (Enhance Buoyancy of Contaminants) Step 2: Induce Spiral Flow (Create Buoyancy/Density Separation) Conventional Tubular Membrane Laminar Gas/Oil/Solids flow through core of Flow membrane tube & water flows along membrane surface SW I RLT EX S YS T EM ENERGY CONSUMPTION AND ANNULAR FLOW GRAPH/CHARTS HERE Swirltex’s patented technology significantly reduces energy consumption because of the volume of air the we inject into our process. Our annular flow pattern increases crossflow efficiency which reduces fouling and solids buildup on the membrane. THE SWIRLTEX SOLUTION Significant Flux Improvements With the Swirltex process implemented, tubular membranes consistently operate at higher stabilized permeate flux rates compared to conventional tubular membrane operation.

Several industries reclaim the majority of accessible wastewater, depending on specific end-use needs and effluent standards. Swirltex's membrane process ensures a substantial decrease in bacteria counts within the treatment system effluent, enabling its versatile reuse across diverse industrial operations. CONCLUSION Industrial wastewater specialists On August 1st, 2023, Swirltex announced that they have been awarded a project to supply their patented “Buoyancy Enhanced Membrane Filtration” technology for Coal wastewater treatment with a leading USbased coal company.
