The conductivity of purified water in the primary system is less than 10us/cm.
Second level system water conductivity less than 2us/cn.
Third level system water conductivity less than 0.5us/cn.
Three differences:
1, through the journey is not the same, out of the product is not the same. Conductivity is a very obvious indicator, of course, if the water purifier is not well maintained, the last out of the water quality may not be much difference.
2, conductivity is divided into different areas.
3, the purity of water is not the same.
4, the amount of interference impurities inside the pure water is different.
Expanded Information:
1, the structural design should be simple, reliable, easy to disassemble.
2, in order to facilitate the disassembly, replacement, cleaning parts, actuator design as far as possible using the standardization, generalization, systematic parts.
3, the equipment inside and outside the wall surface, the requirements of smooth and flat, no dead ends, easy to clean, sterilize. The surface of the parts should be done chrome plating and other surface treatment to resist corrosion and prevent rust. Avoid paint on the outside of the equipment to prevent peeling.
4, the preparation of purified water equipment should be used low-carbon stainless steel or other proven materials that do not contaminate the water. Preparation of purified water equipment should be regularly cleaned, and cleaning effect verification.
5, water for injection contact materials must be high-quality low-carbon stainless steel or other materials that have been verified not to pollute the water. Preparation of water for injection equipment should be cleaned regularly, and the cleaning effect of verification.
6, purified water storage cycle should not be greater than 24 hours, the tank should be made of stainless steel or verified non-toxic, corrosion-resistant, non-leakage of contaminated ions of other materials. Protection of its air vent should be installed without shedding fibers of hydrophobic sterilization filter.
The inner wall of the tank should be smooth, take over and welds should not have dead ends and trachoma. Should not form stagnant water pollution display liquid level, temperature pressure and other parameters of the sensor. The tank should be regularly cleaned, disinfected and sterilized, and the cleaning and sterilization effect verification.
