RO membrane DOW-DUPONT 4040 high pressure LC HR4040:
– Capacity: 11 m3/day
– Pressure: 225 PSI
– Stabilized NaCl Rejection: 99.5 %
– Original: China
The Dow membrane is composed of micro-filters (0,0001 Micron) << virus size.
– RO membrane is capable of completely removing bacteria and viruses, heavy metal ions, ions causing hard water phenomenon such as Mg2 +, Ca2 + … to remove organic impurities, bacteria, viruses and radioactive substances.
– Scientists recommend RO membrane to replace in a period of 18 – 24 months. If the inlet water is clean, the filter life can be extended to 24 months. If the water is contaminated with limestone, bacteria, virus … then the life expectancy is about 18 months you should replace it.
