Qirui Company Can Provide The Pre-treatment Equipments As Follows:
1 Quartz sand, manganese sand filter
2 Active carbon filter with the steam sterilization function
3 Softner
4 Chemistry meter additive drug equipment
5 Micro-filter
6 UV sterilization equipment
Main Desalination Equipment For Pure Water System:
1 Double stage reverse osmosis RO equipment
2 Single stage reverse osmosis RO equipment
3 Single stage reverse osmosis RO + ion exchange mixed bed equipment
4 Double stage reverse osmosis RO + EDI (CEDI) equipment
5 Single stage reverse osmosis RO + EDI (CEDI) equipment Brief Introduction: It uses the unique principle of anti-infiltration to produce purified water and can reduce inorganic salt, organisms and bacteria in water considerably. It is mainly used for bottled purified water, living water, residntial domestic water and far-ocean fresh drinking water. Reverse osmosis is a kind of membrane separation techniques which was developed in 1980s, it mainly uses the osmosis principle of the semi-permeable membrane, and brings a kind of pressure that opposite to the force in natural osmosis direction in a certain way, then the water in the strong solution osmosis into the thin solution, this is reverse osmosis. The unit which is made up of reverse osmosis components is reverse osmosis unit. The pre-treatment equipment provided by the Qirui can be rinsed by the hot water of 85 temperature (if the customers have special requirement, active carbon filter can design as the pure steam washing for sterilization at the most certain), assure and control the index of the microbe. The filtration tank with stainless steel adopts 4mm without pollution glue inside the tank, preventing the inside wall of the stainless steel tank being corrupted. Features:
1. Applied in the areas where the raw water contains little salt
2. Low total quantity of carbon(organism)
3. Non-contamination emission
4. Simple structure
