PWT ‘s  ready to use mixed bed resins are specially prepared high quality ion exchange resin mixtures, designed for direct purification of water. The ratio of component ion exchange resins is engineered to provide high capacity performance of the ready to use mixed bed resin which depends on the application. Several of the mixed bed resins are available with indicators which facilitate ease of operation when a simple visual indication of exhaustion is desired.

Resinex™ MX-21 is a ready-to-use mixed bed resin specially designed for the production of fully demineralised water, e.g. circulating water in EDM applications. The product is made up of a 1:1,5 volumetric ratio of Resinex™ K-8 and Resinex™ A-4 to offer a very low conductivity in the outlet during operation. The high operating capacity offers an economic advantage and the type 1 functional group in the anionic compound guarantees a high purity, silica free water grade of resin which has a higher capacity that cheaper grades of resin on the market which will have a lower capacity

About Pure Water.

The ISO based its specification on ISO 3696:1987, and specifies three grades of water: Grade 1, Grade 2 and Grade 3, where Grade 1 is the most pure (see below):

Water quality parameters for ISO grades.

Parameter Grade 1 Grade 2 Grade 3
pH value at 25oC 5.0–7.0
Conductivity (μS/cm)  at 25oC, max 0.1 1.0 5.0
Oxidisable matter Oxygen content (mg/l), max 0.08 0.4
Absorbance at 254 nm and 1 cm optical path length, absorbance units, max. 0.001 0.01
Residue after evaporation on heating at 110oC (mg/kg), max 1 2
Silica (SiO2) content (mg/l), max 0.01 0.02
