Waste Water


Our Jash mono series of knife gate valves solves one of the leading problems in wastewater management: Leakage to atmosphere

For too long wastewater was just dumped back into the environment. Now we are paying the price. In most modern cities waste water is a real Witches Brew. Human waste is typically only 34 percent of the mixture. Industrial processes, storm water inflow and groundwater infiltration make up the balance. On the residential side the recipe includes things like decaying organic matter, excessive nutrients like ammonia, phosphorous and nitrogen along with bacteria, viruses and disease-causing pathogens not to mention other substances such as pharmaceutical and personal care products. On the commercial side, agriculture and industry produce a toxic mass of pesticides and inorganic chloramines along with those heavy metals like mercury, lead, cadmium, chromium and arsenic.
