In order to meet the needs of users, reach the standard water quality and reduce pollution at all levels as much as possible, in the process design, standard tap water is used as source water, and pretreatment systems such as medium filter, activated carbon filter and precision filter, RO reverse osmosis host system and ion exchange mixed bed system are added.
Standard configuration of reverse osmosis water treatment equipment in laboratory
1, the first stage 5umPPF filter, to remove suspended solids, colloids, particles, rust, sediments, etc. More than 5 microns in water.
2. The second-stage CTO filter screen absorbs different colors, odors, residual chlorine, halogenated hydrocarbons, heavy metals and other impurities in water.
3. The third stage 1umPPF filter mainly removes impurities above 1um, so as to meet the water inflow requirements of the subsequent reverse osmosis membrane.
4. The four-stage reverse osmosis membrane can remove the salt in raw water, and the salt removal rate in water is above 90%.
5. The post-stage pure water column is used to deeply absorb impurities that have not been removed from the water. With imported exchange resin, the effluent resistivity can be >:10Ω/cm (i.e. conductivity
Remarkable characteristics of reverse osmosis water treatment equipment in laboratory
1. Solute and water can be separated without phase change at room temperature, which is suitable for the separation and concentration of heat-sensitive substances. Compared with the separation method with phase change, the energy consumption is lower.
2. Reverse osmosis membrane separation technology can remove impurities in a wide range.
3. The desalination rate and water reuse rate are high, and solute with particle size larger than several nanometers can be intercepted.
4. The reverse osmosis water treatment equipment in the laboratory uses low pressure as the membrane separation power, so the separation device is simple, the operation, maintenance and automatic control are simple, and the site is safe and hygienic.
