Industrial Oil Water Separators Design & Specification

industrial oil water separators

Industrial Oil Water Separators are increasingly important when helping meet ever stringent environmental regulations.

Industrial Oil Water Separators

The industrial oil water separators applications include tank farms, process drains, outfalls, process optimization, machine tool coolant, and vehicle maintenance operations. Many industrial facilities contamination occurs from the mixture of leaked or spilled oil and wastewater.  Discharged to surface waters requires pre-treatment which helps meet the “no sheen” requirement of the Clean Water Act. If discharged to a sanitary sewer, sewer facility authorities require permission and permits since strict laws govern discharged effluent water into surrounding lakes and rivers.

Clean Water Act (CWA)

The basic law covering oil in water discharges is the Clean Water Act (CWA). Although the CWA  primarily controls discharges from Publicly Owned Treatment Works (POTWs or sanitary sewer plants) and toxic discharges from industrial plants, it also governs discharges of petroleum and other hydrocarbons into the waters of the United States. Any discharges other than those covered by the permit are illegal.

Discharging Wastewater Effluent 

When the choice exists of either discharging wastewater effluent into surface waters (lakes, streams, etc.), or to the sanitary sewer, the best choice is often the sanitary sewer because the outlet oil concentration requirements are less stringent. Sanitary sewer plant operators usually require that any plant wastewater streams meet certain required characteristics or be pre-treated to meet those requirements. Strict pre-treatment requirements usually range from 50 mg/L to about 150 mg/L of oil. MSR industrial oil water separators achieved these requirements.

Contamination Sources

Industrial oil water separators must process oily water that before discharge. Most oily water contamination comes from leaking oil and fuel spills associated with tank farms, process drains, outfalls, process optimization systems, machine tool coolant processes, and vehicle maintenance operations. Inevitable environmental and economical problems happen when rainwater mixes with these oils.

Some  industrial facilities have dedicated wastewater treatment equipment, but most wastewater,  is directed to the local sanitary sewers. This effluent water must meet the requirements of the facility authorities. Some industrial plants require oil water separation which purifies water allowing for reuse or recycling. Some chemical facilities or other plant refineries need internal oil water separators for processing outfall streams.

Mohr Oil Water Separators

MSR  industrial oil water separators pre-treatment systems coming in any size or configuration. They are generally relatively small in chemical plants because plants try to minimize their waste streams. Our water pollution control system designs handle either gravity or pumped flow on a single-pass or re-circulating basis. MSR coalescing plates separate oil from circulating water or other aqueous phase systems This allow for more economical reuse of water streams or prevents oil in the water stream from causing problems elsewhere in the system by fouling heat exchangers or catalysts. Some industrial plants separate oil from water, purifying water for and reused or recycling.

Carbon steel industrial oil water separator vessels have a special corrosion resistant coating both internally and externally. Systems come in stainless steel, aluminum or corrosion resistant plastic, and for use in existing tanks or concrete pits. Use systems as either below ground or above ground separators where necessary. MSR coalescing systems’ relatively wide spaced plates do not plug easily like coalescing cartridges (which require frequent cartridge changes) and MSR systems are guaranteed to produce effluent quality that will meet or exceed discharge requirements.

Preparing for the Future

A more cost-effective and reliable method for oil in water removal is needed because environmental regulations continue to become stricter. They require lower concentrations of hydrocarbons in effluent water. API type systems are inadequate to ensure proper pre-treatment and it is necessary to utilize a high-efficiency system for oil removal. MSR HE-Plate multiple angle separators ensure effluent water quality that meets or exceeds the requirements for federal, state, and local regulations. Specially designed systems for sustainability under difficult conditions and continue to benefit a number of different industrial plant operations.
