Reverse Osmosis Reject Brine Management

Reverse osmosis (RO) is widely used to purify water for industrial and commercial operations. It helps turn brackish or salty source water into usable fresh water—but it also leaves behind concentrated wastewater known as RO reject brine.

This leftover water contains higher levels of salt and may also contain organic materials and other minerals. Managing it can create challenges, including unpleasant odors, slow evaporation, and increasing storage or disposal costs.

A Practical Solution with ESM’s H.E.A.T.

ESM’s H.E.A.T. process uses customized microbial mixes to help facilities manage RO reject brine within existing evaporation ponds. The approach is designed to address common brine management challenges without requiring additional infrastructure or external power.

Depending on the characteristics of your brine and operating conditions, H.E.A.T. can help:

Control odors associated with organic materials.
Reduce organic contaminants in concentrated wastewater.
Improve evaporation rates to support pond management.
Use existing infrastructure without adding energy-intensive equipment.

Find the Right Approach for Your RO Wastewater

Every water purification system produces a different brine stream. ESM works with you to understand your wastewater, current disposal methods, and operational needs to determine whether H.E.A.T. is a suitable solution.
