The PUFS-E offers processing capabilities of up to 100 gallons per day for mixed oily wastewaters. Operating as an ultrafilter or nanofilter, this small system is driven by plant air and requires little operator attention. Waterlink membrane systems are in use worldwide providing a positive barrier between wastewater and the environment. Working independently or in conjunction with centrifuges, filters, chemical treatment systems, oxidation and distillation, Waterlink applies its equipment to disposal of oily wastewater, recycling cleaners in aqueous parts washers, reduction of suspended solids from metal finishing applications, recycling of floor scrubbing waters, and reduction of BOD and COD in mixed wastewater applications. Operating at low pressures, MF technology can separate suspended and colloidal materials down to 0.1 micron.
Membranes made of polymers or ceramics are available for high temperature applications.
This technology will reject oil and solid particulate down to 0.005 micron on the surface of the membrane, allowing water and dissolved salts to pass through a barrier. UF is available in wide channel tubular configurations allowing for trouble-free processing in the presence of solids or in narrow channel designs which densely pack membrane area into elements for energy efficiency. NF is a tight membrane which rejects dyes, and some large molecular weight compounds. NF membrane systems operate at low pressures with minimal pretreatment. In use for recycling rinse waters, removing dye penetrants from water and COD reduction, this technology is easy to use and economical.
