Introduction:

Industrial liquids may be processed to remove oily and particulate contaminants for water pollution and air pollution abatement, to recover valuable resources, or to purify circulating liquid streams.

Designs by Mohr Separations Research are cost effective, require little or no energy to operate, can easily meet the requirements of the Clean Water Act, and can recover valuable hydrocarbons or other oils. In addition, since there are usually no moving parts and the equipment is self-cleaning, operations and maintenance are simple, easy, and inexpensive. Removals up to 99.9% of non-dissolved oil are possible.

Contaminant Removal:

Hydrocarbons in industrial wastewater can be troublesome both to publicly owned treatment works (POTW) and to the plant originating the waste. Some hydrocarbons are volatile and would contribute to VOC emissions from a POTW. In addition to being a VOC problem, too much hydrocarbon content in the incoming water would be detrimental to the health of the microbes in the sanitary plant.

The basic law covering discharges is the Clean Water Act. Permits for point sources including POTWs under this system are granted by the Environmental Protection Agency (EPA) or by states with EPA approved programs.

Often, the choice of pretreatment methods is dictated by the requirements of regulatory agencies.

Facilities that can benefit from designs by Mohr Separations Research are:

Resource Recovery

Similar technology can be used to capture for sale or reuse any non-miscible liquids that have an industrial value. Examples of typical systems are:

Stream Purification:

In many facilities, liquid streams are recirculated as part of the process. These streams acquire "tramp oils" of various types that can be detrimental to operations. Examples include:
