Product Details

Lanlang TY MB-2 mixed bed di resin is a ready-to-use homogeneous mixture of cation exchange resin (dark colored grains) and anion exchange resin (light colored grains). Lanlang TY MB-2 mixed bed di resin allows to reach operation condition with minimal water consumption for the primary washing of the resin. Using mixed bed di resin for polishing water with an input electrical conductivity of not more than 10 µS/cm, is usually attained an electrical conductivity ~ 0.1 µS/cm of purified water with neutral pH.

Usually, the spent mixture is discarded and replaced with a new one.

mixed bed di resin

Lanlang TY MB-2 mixed bed di resin can be used in regenerative mixed-action filters depending on the water treatment process. In such installations, the layer should be separated into cation exchange resin and anion exchange resin by reverse flow of water. After that, the cation and anion exchange resin can be regenerated separately.
