Envent Corporation: A National Leader for On-Site Water Treatment

Envent is a national leader for on-site water treatment used for pipeline hydrostatic testing (also known as pipeline hydrotesting) in the petrochemical and refining industries. We design our treatment systems to remove specific contaminants and meet all discharge permit requirements for general water quality, volume, and flow rate. Envent manages the largest fleet of tank and pipeline hydrotesting equipment in North America.

We Meet Your Project Challenges

Envent Corporation has the equipment to meet any water-treatment challenge under any conditions. Our hydrotest water treatment services include permitting, equipment delivery and set-up, media loading and extraction, system operation, media disposal, discharge monitoring and final project reporting. Our systems employ activated carbon, zeolite and clay media, dissolved air flotation units, air strippers, particulate filters, and advanced oil/water separators.

Envent is Ready to Mobilize

Envent mobilizes its teams 24/7 to pipeline stations, terminals and refineries to perform treatment of the water following the pipeline hydrotest. We work with your environmental engineers to acquire the necessary NPDES or POTW permits, get the specifications for the right equipment, treat your water; sample and work with the laboratory to ensure testing requirements are met, and file discharge reports as needed.  In short, we do it all – which is exactly what you expect from a specialist!

If you represent an engineering firm, you will appreciate the support you get from our engineers and project managers to research equipment specifications and draft safe work plans and operations manuals. Please contact Envent engineers to help scope your next tank or pipeline hydrotest project.
