H2S oxidation system for water treatment facilities

A new water treatment facility in the town of Jupiter, Florida, was causing a serious odor problem. H2S removed from the purified water was being released into the atmosphere. Complaints about the odor came from the residences and businesses downwind of the treatment plant.

A turnkey LO-CAT® Hydrogen Sulfide Oxidation System designed to process 30,000 CFM of air containing 250 ppm of H2S solved this problem.

Due to the scarcity of fresh water available for treatment by conventional means, the town of Jupiter chose to be the first in southeast Florida to drill into the Floridan aquifer, located approximately 1,200 feet below ground.

A 6 MGD treatment plant, consisting of reverse osmosis, air stripping and chemical treatment, was designed by the engineering firm retained by the town. Because the well water is brackish and contains dissolved H2S, it must undergo pre-treatment prior to entering the town’s regional water distribution system.

In the reverse osmosis process, the aquifer’s brackish water is pressurized and forced through a semipermeable membrane. The dissolved CO2 and H2S pass through the membrane along with the purified water. The purified water is then passed through an air stripper to remove the dissolved H2S and CO2.
