Ultra-pure water equipment, the standard value of the hardness of the effluent: ≤ 0.03mmoi / L (water hardness ≤ 8mmi / L), the standard of ultra-pure water is fully compatible with the production of medical injectable preparations. The same equipment also has strict requirements for water, in general, according to the quality of raw water to install a pretreatment system and reverse osmosis equipment, the use of reverse osmosis equipment, the terminal water as EDI ultrapure water equipment into the water. When the tap water hardness is too high, but also have to use to soften the water equipment, the subsequent equipment to play a protective role.
Testing water softening equipment water hardness:
After installing the water softening equipment, it is necessary to debug it. Detection of soft water hardness is generally used titration method, titration method is based on the indicator color change, and then through the calculation of the results. But using this method requires the configuration of specialized agents. In addition, the method of testing water hardness and the use of hardness meter, water hardness analysis box.
Hardness meter is a kind of instrument that can directly detect the water hardness. The LCD screen on the hardness meter can directly display the water hardness value. Water hardness analysis box is the preparation of the agent in the vial, the test bottle will be put into the water softening equipment when testing the water quality of the water, shaking evenly after the comparison of the color plate can be derived from the water hardness value.
