The waste water system: direct emissions - washing agent regeneration of water systems mixing water (containing hydrochloric acid regeneration / washing liquid and alkali washing liquid) Disposal - System concentrate (reverse osmosis membrane group, Ningxia high / low ammonia, ultra outer limit filter group) or alkaline regeneration waste. Multi-effect evaporation technology is several multi-effect evaporation system evaporator in series, high / low ammonia system performance, the front one evaporator evaporated under a secondary gas into the evaporator, high / low ammonia system manufacturer, as a heating steam, while the next evaporator is condensed as distilled water. This in turn before an efficient use of secondary steam evaporator as a heat source for the next effect. As the international advanced level of chemical engineering and chemical machinery of well-known suppliers, Han Nuoke technology has won the "high-tech enterprises," "contract and trustworthy enterprise" and "advanced production and management units", "consumer satisfaction units," bank " AAA grade credit enterprise "and other honorary titles.
