The odor control system is a dual-train 2-stage wet process system. The process involves odorous air from the facilities degasifiers entering the first stage scrubber from the bottom, where it is drawn upward through the system's synthetic media exiting from the top into ducting where it is carried to the bottom and enters the bottom of the second stage, again flowing upward through the similar media to the first stage and exiting through a tall stack to atmosphere. The concentration of hydrogen sulfide in the odorous gas is reduced more than 99%. Additionally, chemically treated water is recirculated from the lower sump and sprayed out above the media which acts to increase the air to water interface and causes the hydrogen sulfide to be adsorbed into the water. Sodium hydroxide in the first and second stages. While sodium hypochlorite is added only to the second stage. A continuous overflow of makeup water carries away the precipitated sulfides formed during the chemical reaction and is disposed of directly into the County wastewater system.


INJECTION WELLS


Concentrate or reject from the membrane process is collected in a sump and pumped from there into deep injection wells. There are two wells #1 is 3330 feet deep, #2 in 3200 feet deep.A hydropneumatic tank supplies air pressurized water to packing which interfaces with the deep well aquifer this prevents flow up through the annulus space between the well casing and the discharge piping.
