On-Site Water Treatment

Envent quickly dispatches our wastewater engineers to design and mobilize a treatment system capable of treating any type of industrial wastewater. We utilize activated carbon systems, zeolite and clay media, dissolved air flotation units, air strippers, particulate filters, oil/water separators and UV/Ozone and bioreactor treatment units.

TYPES OF WATER TREATED

• Industrial Wastewater
• Petroleum and Heavy Metal Contaminated Groundwater
• Storm Water
• Landfill Leachate
• Oil Field Petroleum Solids Control
• Terminal, Pipeline, and Refinery Wastewater
• Hydrotest Water

Example Water Treatment Projects
Refinery Wastewater in Slops Tank: Project required portable Dissolved Air Flotation Unit to flocculate emulsified oil, chemical neutralization of sulfides and pH, and all vapors captured and vented to a thermal oxidizer. The thermal oxidizer was monitored with a CEMS unit in compliance with NSR Subpart J.

Power Plant Water: 175,000 bbls of fuel oil and MtBE contaminated water accumulated in fuel oil tanks is treated with oil/water separation, emulsion breaking chemicals, filtration, activated carbon and clay based media prior to discharging into the river bed under and NPDES Permit.

Pipeline Hydrotest: 110,000 bbls of crude oil and benzene contaminated wastewater is treated and discharged to a man made dirt berm under an NPDES permit. Treatment systems included bulk separation of free product, filtration, air stripping followed by activated carbon adsorption.

Refinery Groundwater Treatment: MtBE and gasoline contaminated groundwater from pipeline release. Water pumped and treated over 20 million gallons. Water treated using the proprietary Envent Mobile MtBE Treatment System (EMMTS), a hot water air stripping unit.

Municipal Sewer Neutralization Project: Neutralize for pH and Chlorine 45 million gallons of water form a municipal sewer system. Envent utilized it’s proprietary mobile neutralization unit. Treated water used for irrigation at a university.
