PURIFIED WATER PLANTS
Granting the best quality in terms of bacterial purity. Stilmas’ double stage reverse osmosis plants constitute the most reliable solution for the production of purified water and the only solution for the production of highly purified water.
Stilmas’ double stage RO plants are designed fully in compliance with the standards requested by the International Pharmacopoeias. Its pure water generation plants are the result of many years of experience and constant technical development. They represent the simplest, safest and most reliable water purification method for:Production of ultra-pure water for Pharmaceutical, cosmetic and food industries.Production of deionized water for industrial use when high bacteriological and chemical quality is required.
Special plants execution are possible for the production of Highly Purified Water and low endotoxin Purified Water, without any need of ultrafiltration section or additional treatment.
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.
TECHNICAL DESCRIPTION
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:
Reverse osmosis membraneThe 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.
