Features Ready to use Easy to prepare solution and use water Directions for Use UNICHEM RD polymer may be loaded manually or pumped directly into the dilution tank from the container. Prepare stock solution (1.0 to 1.5%w/v) of the polyelectrolyte using filtered water. Prepare feed solution by diluting the stock solution about ten times directly or on-line using filtered water. For small systems chemicals can be dosed by gravity or by dosing equipment. However, for large systems use of dosing system is recommended for optimum efficiency. Handling Do not store the material in open. Keep the container tightly closed when not in use. These products exhibit very low order of oral toxicity. No special care is required in handling these products.
