ABSTRACT:
Advanced submerged membrane systems are provided. Said submerged membrane systems have multiple membrane modules comprising of strips of flat sheet membrane, bundles of self-support hollow fiber membranes braided together for reinforcement, tubular membranes, and braid supported hollow fiber membranes. Said submerged membrane systems have alternating relay, or two-way floating switch or computer to control filtration and back flush/pulse cleaning. Said submerged membrane systems have an oscillating motor, and aerator which can generate liquid vortex (whirlpool) flow around membrane to keep membrane from fouling. The present invention provides advanced submerge membrane systems at very low cost for drinking water production, wastewater treatment and membrane bioreactors for biotech, pharmaceutical and other industries.
