A pre-cast cement manufacturer, using ground water with extraordinarily high concentrations of both hardness and hydrogen sulfide (sulpher), was experiencing inordinately expensive equipment replacement and repair costs as a result of the corrosive nature of this process water.
Hydrogen Sulfide or â€˜sulpher waterâ€™ as it is frequently called is highly corrosive. The H2S04 â€˜off gassesâ€™ readily, and will attack any metal it comes in contact with. The resulting precipitate can actually clog orifices and promote under deposit corrosion.
IFM worked on this problem from two directions; the hydrogen sulfide and hardness required removal and the equipment was to be placed in a fairly hostile manufacturing environment.
By employing hydrogen peroxide injection (hydrogen sulfide removal), depth filtration, carbon absorption and softening, the water problem was solved. Through the use of equipment that was corrosion proof (fiberglass, plastic, NorelÂ®, and stainless steel) a robust and efficient treatment system was established.
IFM currently provides preventive maintenance on this system.
