SEPLITE® Monojet™ MB610U
SEPLITE® MB 610U is a semi-conductor grade ion exchange resin mixed bed which is specifically designed for final polishing service in the highest purity water treatment applications, composed of capacity equivalent mixture of strongly acidic cation (SAC) and strongly basic (type I) gel anion (SBA) resins.
The resins are highly regenerated and specially cleaned in order to comply with the specifications of producing high purified water, such as low TOC leaching, high operating capacity for one-use application.
With its uniform particle size which enables excellent kinetic performance and high service flow rate, the low fines result in very low pressure losses compared with Gaussian distributed resins.
It is specifically designed for use in Non-regenerable final polishing mixed beds in ultra-pure water systems in the semiconductor industry and similar demanding applications.
