Water treatment for cement plant wastewater — H2O IQ

A cement plant wastewater treatment system has to remove minute particulate that remains after production. This task is more important when a closed system - the industry standard - is in place and waste water is reused over and over. Here we discuss why and how important is water treatment for cement plant.
