INDUSTRO-SEP® Industrial Liquid Waste Separator
Why Membranes?
Membrane separation process is an excellent water treatment for industrial wastewater purification and recycles. Membranes can be designed to remove different forms of solids depending on inherent porosity and selectivity. A broad spectrum of solids--suspended, oily emulsions, grease, soluble salts, organics and heavy metals-- can be removed from waste water. The permeate or product water can be reused in the process to reduce costs or discharged with much reduced impact on the environment.
The Process:
Water contaminated with emulsified oil, grease or other solids from an industrial effluent is forced through porous polymeric or ceramic membranes at sufficiently elevated pressure levels. A clean permeate emerges from the low pressure side of the membrane while the target solids remain on the high pressure side. The contaminant levels increase as the feed solution is being concentrated to much smaller volumes for more efficient waste treatment. The concentrated stream is pumped at high cross-flow velocity on the membrane surface to carry away most solids before they have the chance to plug up the membrane. The cross-flow filtration greatly reduces the potential of membrane fouling. Moreover, membrane cross-flow filtration requires less energy than processes such as evaporation since it is effected by mechanical compression without a phase change. Membrane separation processes can be specifically designed for various industrial waste water applications with suitable pre or post treatments to keep the membranes in service for many years.
