Water Treatment Material

We provide various water treatment materials such as activated carbon, filter, UF membrane, NF membrane, RO membrane, etc. to optimize QCD and fit with environmental requirements for customers.

Separation Method

We provide the best solution through combining various materials due to composition of water as below table.

Cartridge Filter

We provide various filters such as spool type filter which is 0.5〜200μｍ, and pleated filter which is 0.1〜50μｍ, etc.

Activated Carbon

Activated carbon is composed of porous structure, and its surface area is 700〜1,400㎡ per gram, so that it can adsorb a lot of impurities. If such impurities are more water-repellent and their molecular weight are larger, it’s more easily adsorbed. We can provide various types of activated carbons due to customer’s usage.

Membrane

膜分離

UF membrane can treat macromolecules such as protein, enzyme, whose molecular weight shall be 5,000-300,000 and virus, emulsion, whose particle size shall be 1-100nm. We can provide various types of UF membranes due to customer’s usage.

Hole size of RO membrane is very tiny and it is also called non-porous membrane. Only extremely low molecular such as molecular gas and inorganic ion are able to be passed through. It is applied for the system to make sea water into fresh water and the system to make ultra-pure water. We can provide various types of RO membranes due to customer’s usage.

RO Water

Nano Filtration shall selectively pass monovalent ion such as Na+, Cl- and shall not pass through divalent ion and pigment. Moreover, it shall pass through the size Mw100-200 such as amino acid and shall not pass through the size Mw300-3,000 such as oligosaccharide. We can provide various types of NF membranes due to customer’s usage.

Ceramic

Ceramic is durable and heat-resistant, so that it can be applied for various cases.
In addition, running cost is relatively lower as it can be reused if we do back wash cleaning. We can provide various types of ceramics due to customer’s usage.

イオン交換

Ion-exchange resin abstract and release ion which is contained in raw water.It can make purified water through eliminating cation such as Na, Ca, Mg, etc.
and anion such as Cl, carbonic acid, etc. We can provide various types of ion-exchange resins due to customer’s usage.

Electro Deionization (EDI) is the system which can make purified water, which abstracts ion from RO water. It is composed of cation-exchange membrane and anion-exchange membrane, which are placed between desalination chamber and and concentration chamber. Ion in desalination chamber is eliminated by ion-exchange resin and ion-exchange resin shall be continuously recycled with direct current. We can provide various types of EDIs due to customer’s usage.
