For a small community, Greenfield, Mo., was plagued with what appeared to be major inflow and infiltration (I&I) problems. The sewer pipes...
EMIT Water Discharge Technology, LLC selected Severn Trent Services' Higgins Loop Continuous Countercurrent Ion EXchange (CCIX) system to provide oil and gas producers with water purification services.
The patented system will purify byproduct water created in the production of Coal Bed Natural Gas (CBNG), making the water suitable for discharge into the environment.
During the production of CBNG, water pumped with methane gas contains high levels of sodium and bicarbonate and, in some cases, chlorides and sulfates. Federal and state water regulations prohibit the discharge of this water into the environment or for irrigation, due to its high salt content.
With Severn Trent Services' Higgins Loop CCIX technology, EMIT can economically and efficiently treat water used during the production of CBNG for environmental reintroduction and reuse. The Higgins Loop system utilizes I-X resins in a highly efficient resin-contacting system to remove sodium from the water and concentrate it into a dense brine solution byproduct that may even be useful within the oil and gas industry. Removing sodium from the water lowers its pH balance and reduces bicarbonate levels by extracting carbon dioxide gas from the water.
