----- Quartz sand filter

This device is used in the first filtration of water treatment. It consists in 304stainless steel. There is quartz sand inside. It divides coarse sand, medium sand and fine sand. It will stop suspend substance through the good quality quartz sand, and also protect the following machines and also clean the water this machine can achieve the back washing itself through the manual valve device, and can prolong the life of machine also.

----- Active carbon filter

Activated carbon filter is used in the second filtration of water treatment and filter medium is activated carbon. It can adsorb Hg, plum bum and other heavy metal, organic contamination, odor and improve water sense

----- Sodium Ion exchanger

The machine also called softener, that soften theory is Exchanging Na** of resin itself instead of Ca**Mg** of water resource with Ion to make water resource soften and become soft water. The ion exchange soften machine is used for cutting down hardness of water.

----- Precision filter

This filter is made of stainless steel as a small tank which contains precision filter membrane, it only allows un-treated water go through the membrane, and does not allow any liquid go through another part, so it can filter the un-treated water. It also can be used in petroleum industry, pharmacy industry, wine making industry, beverage industry and higher quality water industry.

----- Reverse Osmosis(for pure water)

Reverse Osmosis is the device that uses semi-permeable membrane under the pressure difference’s function to make the salt water desalination and purification. It is on the contrary of natural direction, so it is called reverse osmosis. It can remove more than 97% solubility of salts in the water and more than 99% of the gel, micro-organisms, and particulate organic matter and so on, can reach the national standards totally after treatment by this device. It is the first choice equipment of purified water. RO usually has I and II.
