Reverse osmosis membrane training

100L/H first -level reverse osmosis equipment uses reverse osmosis membrane and technology. This equipment consists of three parts: pre -processing, first -level reverse osmosis treatment. The water output rate ≤ 10 μs/cm, and the water production is 100L/h.

Water entry requirements: Use municipal water supply that meets the standard of drinking water in the country.

1. Pre -processing

Suitable pre -processing is very important for long -term safe operation of the reverse osmosis device. With pre -treatment that meets the requirements of reverse osmosis into the water quality, it can ensure that the flow of product water (infiltrated water) rem--ns stable; the dedue rate is m--nt--ned for a long time on a cert--n value; the product water recovery rate can be unchanged; **; Specifically, reverse osmosis treatment is to do:

⑴ To prevent pollution on the surface of the membrane, that is, to prevent suspended impurities, microbial, colloidal substances attached to the surface of the membrane or dirt -blocked membrane component water flow channel.

上 Prevent scaling on the surface of the membrane. During the operation of the reverse osmosis device, due to the concentration of water, there are some embarrassing salts such as CACO3, CASO4, BASO4, CAF2 and other deposits on the surface of the membrane.

(3) Make sure that the membrane is exempted from mechanical and chemical damage, so that the membrane has good performance and a long life.

This device is composed of automatic mechanical filters, automatic activated carbon filters, automatic sodium ion softness, and security filters.

The sand filter uses a glass reinforcement barrel, which is equipped with quartz sand and iron ore. It can effectively remove the suspended objects cont--ned in the water, condensed sheets, and bonding glue particles and iron ions that can not be removed with the sedimentation method.

The carbon filter uses a glass reinforced reinforced reinforcement barrel, the interior activated carbon can effectively remove organic matter, some heavy metal ions, etc. in the water.

The sodium ion softter uses a glass fiber reinforcement barrel, the interior sodium cation exchange resin, and the raw water exchange the resin through the sodium cation, so that the hardness ingredients in the water CA2+ions, MG2+ions, etc. are exchanged with NA+ion in the resin, so as to adsorb the CA2+ions in the water, MG2+ions, etc., soften the water.

The security filter is 5 micron PP filter, and the fine suspension in the water is filtered.
