Produced FRAC Wastewater
Lowest CAPEX and OPEX Solution in the Oil & Gas Industry

5000 m3/day Chemical Free Electrocatalytic Oxidation System EOX

Liquid Environmental Solutions Inc (LESI )is a world-leader in chemical-free produced and frac water treatment systems in the oil & gas industry for broad spectrum contaminant removal. Our systems have lower maintenance, higher runtimes and huge savings compared to any other technology in the industry.

1. Proven & Effective. LESI uses electrocoaguation with iron electrodes with ozone as a catalyst to create Fenton’s Reagent as one of the most powerful oxidants on the planet. LESI and affiliates has been creating produced and frac water solutions for the oil & gas industry for more than 20 years. LESI systems operate in countries around the world.

2. Easy to Bring from Design to Implementation Mobile, modular or fixed plant, we can bring your total solution to reality on time and on-budget with a compact footprint and the lowest operating cost by volume in the world.

Operational Flow

Our produced and frac wastewater treatment process can scale up to any size and flow rate while maintaining the lowest CAPEX and OPEX costs in the industry. We will work with you to design ,engineer and commission the solution aligned to your specific project needs. Here are the steps:
