Reverse osmosis separation is such a separation process whereby a solvent (water) overcomes solvent osmotic pressure and pass through reverse osmosis membrance at a given pressure 0.8~10Mpa, and ions in the solvent are intercepted. Separated substance has its size of l-l.5×10-4 μm. As such, sii metalions and non-metal elements below the NO.11 element sodium listed in the periodic table will be effectively intercepted. Purifying Process and Features: 1) Pre-filter: To remove mechanical foreign matter in water 2) Ultra-filter: To remove molecular level bacteria, virus, colloid, etc. in water 3) Reverse osmosis unit: Tore move residual chlorine, odor and color in water and to improve drinking water taste 4) Power, V, Hz: 220,50 5) Heating power: 750W 6) Water capacity: 10L/hr 7) Desalination: ≥95% 8) Water-in TDS ≤1,200mg/L 9) Water-in pressure ≥ 0.036Mpa 10) Water heating temperature: 85~95oC 11) Water cooling temperature: 5~15oC 12) Overall dimension: 340 x 340 x 1,000mm 13) Net weight: 28kg
