Ion exchange column is a traditional water treatment process that involves the equimolar reaction of ions in water and ions on the resin inside the ion exchange column. Simply put, it involves the displacement of various anions and cations in water through anion and cation exchange resins.

Composite bed: Using two exchangers, the anion and cation exchange resins are loaded into their respective exchangers according to design requirements. The raw water first passes through the cation exchange agent, and the cations in the water such as Ca2+, Mg2+, K+, Na+, etc. are adsorbed by the exchange agent. The H+that can be exchanged on the exchange agent is replaced in the water and forms corresponding inorganic acids with the anions in the water; The effluent is then passed through an anion exchange agent, where anions such as SO42-, CL -, HCO3-, etc. in the water are adsorbed by the exchange agent. The exchangeable ion OH - on the exchange agent is replaced in the water and combines with H+in the water to form H₂O。

The water treated by the above-mentioned anion and cation exchangers removes the salt in the water, which is the desalination treatment of the first stage double bed. The effluent water quality is ≤ 10us/cm.

Mixed bed: In the same exchanger, anion and cation exchange resins are filled in a certain volume ratio, and anion and cation exchange is carried out in a uniformly mixed state to remove salt from the water. The effluent water resistivity is ≥ 5M Ω· cm. At the same time, according to different water quality and usage requirements, the effluent resistivity can be controlled between 1-18M Ω· cm

The overall wrapped cylinder body has a freely selectable thickness, high safety, and does not explode the column

RPP and PPH materials have superior anti-corrosion performance

Compared to glass equipment, ion exchange columns made of polypropylene have higher safety and are less prone to bursting. However, their biggest drawback is that they cannot clearly observe the internal situation of the equipment, and the observation holes they carry are prone to material accumulation. Our company has specially developed an ion exchange column specific sight glass to address this situation, which has a large visible area and prevents material accumulation. And it solves the problems of common leakage and easy corrosion of embedded parts.

If you are concerned about the safety of glass ion exchange columns and feel that traditional polypropylene ion exchange columns are inconvenient to use, we recommend that you choose our company's "polypropylene ion exchange column" with a dedicated sight glass.
