TECHNICAL DESCRIPTION

Operating principle

Softened feed water is pre-filled into a break tank. Circulation pump and high-pressure pump, after a final filtration feed the first stage of membranes, the number of which will determine the processing capacity. The osmosed water produced through a further pump system enters the second stage of membranes while the concentrate is rejected. The pure water produced is sent to the storage and the second stage concentrate is recovered to the break tank for consumption optimization. Tank, pumps and filter of the first stage are also used for chemical washing and sanitizing the membranes. The plant configuration of Stilmas’ exclusive design ensures the best performance and operation flexibility, by permitting the periodical recirculation during stand-by conditions for the control of bacterial contamination.

Second stage Break Tank

The double stage RO configuration, with a second break tank between the first and second rack of membranes, is the most updated design by Stilmas and allows to use the second stage RO as a microbial polisher for the PW/HPW (Purified Water/High Purified Water) distribution loop. When no consumption of PW/HPW water occurs, periodically and according to a defined program, part of the water circulating in the PW/HPW loop is reprocessed by the second stage RO membranes.

The result is a high performance with two advantages:

Recirculation of RO package during stand-by phases / the best microbial quality without any need of frequent loop sanitization by heating, ozone or other systems.

Reverse osmosis membrane

The functional characteristic of the membrane is to be able to separate 99% of all dissolved salts in raw water during each stage of the process. It rejects bacteria, pyrogens and organic substances. Stilmas has years of experience in the use and selection of membranes on the market, and will select those that are best suited for each application.
