ROPUR RPI ANTISCALANT

ROPUR RPI Antiscalants are popular in water treatment industry especially the large scale Reverse Osmosis (RO) systems in drinking water production. These antiscalants are more effective in scale control and enhanced dispersant as they form a very good barrier to the RO membranes. They are compatible with the widely used membranes and chemicals, and can be applied to the different water treatment procedures.

The product range of ROPUR RPI Antiscalants is particularly characterized by the compliance with country-specific drinking water approvals such as NSF and KIWA. This compliance assures the antiscalants’ safety for use in this and other regulatory jurisdictions while preserving high water quality.

These antiscalants avoid the formation of scale, which is typical in RO systems, to a great extent, aggregating to the decline of the system’s efficiency and useful lifetime. Due to its ability to prevent the formation and deposition of minerals that hinder water circulation, ROPUR RPI Antiscalants is beneficial as they lower system maintenance expenses and eventual downtime.

Round the world, most massive RO systems depend on ROPUR RPI Antiscalants since they are very reliable as seen by their performance in the marketplace. It means that they can easily integrate with currently existing water treatment systems and that is why specialists choose them in order to increase the efficiency and durability of RO systems.
