Potable & Process water treatment
1. Boiler water chemicals
2. Cooling water chemicals
3. RO chemicals
Reverse osmosis cleaning chemicals and RO antiscalants are specialty chemicals that are added upstream of a reverse osmosis membrane system. These reverse osmosis chemicals are designed to prevent or slow-down mineral scale formation on the membrane surface and increase the efficiency of the system.
4. Heavy metal removal/recovery
5. Colour removal
6. Iron removal
Purolite MZ10 Plus is a black catalytic media used for removing soluble iron, manganese, hydrogen sulfide, arsenic and radium from water supplies. The media has unique characteristics in addition to its catalytic property which facilitates the oxidation reduction reaction of iron and manganese.
Purolite catalyst technology is a proven technology for iron and manganese removal. Purolite MZ10 Plus can be used at high operating temperatures and high differential pressures without breakdown of the media and is classified as a “high rate” media where the filters can be run at very high linear velocities with excellent results.
Water for industrial and domestic uses must be substantially iron and manganese free. In many countries it is a requirement that water for municipal use should not contain iron and manganese concentrations of greater than 0.2 and 0.05 ppm respectively, and preferably below0.05 and 0.02 ppm. In certain industries like pulp and paper mills, tanneries, textile plants, dye houses and laundries, it is almost impossible to operate with iron or manganese bearing waters since they would produce objectionable stains, streaks, spots and off-colors on many manufactured products. Iron and manganese also foul ion exchange resins. Hence, it is necessary to include a pretreatment stage in most ion exchange processes.
7. Fluoride removal
Purolite’s SSTC60 operated in Al3+ form is a Shallow Shell™ technology resin featuring a solid core and functionalized outer shell specially designed for the selective removal of fluoride from water and waste water. The unique Shallow Shell design allows for effective removal of fluoride ions during the service cycle and efficient reversibility and clean-up of the resin during regeneration to give predictable and consistent performance and low leakage over time.
