Water Treatment

CBM – Coal Bed Methane

During the production of natural gas from coal beds water is typically a co-product. Along with the gas the water is brought to the surface. This water can be very high in sodium, this high sodium content expressed as the sodium adsorption ratio (SAR) makes the water detrimental to plants, fish and the environment.

To get the methane out of coal seams water must be continually pumped out. The water contains a cocktail of chemicals including nitrates, nitrites, chlorides and other salts, benzene, toluene, ethylbenzene, other minerals, metals such as arsenic, cadmium , lead and mercury and high levels of total dissolved solids.

The sodium content and other toxic chemicals in the water can be reduced by using ion exchange.
