D Duo Eclipse™ In many industrial processes, any dissolved salts in water can cause problems. Removing all the dissolved salts from water is called deionisation or demineralisation. Duo Eclipse™ two stage deionisers remove up to 98% of total dissolved solids and will typically produce water with a conductivity of less than 20 μS/cm. Flow rates from 0.25 to 4 m3/hr. Ion exchange & Deionisation M METCLEAN™ A patented process capable of removing heavy metals (arsenic, cadmium, lead, zinc, nickel, iron, manganese, arsenic, uranium etc.) from different types of water, including industrial wastewaters.
