A water treatment system for treating coal-bed-methane (CBM) water. The
CBM water treatment system includes a pump system for pumping CBM water
from one or many CBM wells into a common reservoir and a solid-based
sulfurous generator that produces aqueous sulfurous acid to treat the CBM
water and an injection system that increases the amount of calcium
contained in CBM water. In one embodiment, the injection system is a
gypsum injector that injects soluble gypsum into the CBM water. Moreover,
in one embodiment, the solid-based sulfurous generator includes a
hydraulic air inlet shut off valve safety system for automatically
reducing the combustion air to the sulfurous generator when water is not
delivered to the solid-based sulfurous generator. Also, in one
embodiment, the water treatment system includes a control system that
monitors the pH of the treated water to control the water flow rate
through the solid-based sulfurous generator to achieve the desired
concentration of sulfurous acid in the CBM water being treated.
