Membrane Cleaning and CIP
Reverse Osmosis (RO) Membrane Cleaning
Reverse Osmosis is a water filtration process where dissolved solids are removed from water using a thin film composite membrane to effectively filter out the dissolved solids and salts. This thin membrane combined with water pressure allows only water to pass through the material and the dissolved solids are retained by the membrane. These membranes are the most important part of the RO system and are commonly spiral wound made of either: CTA, Cellulose Tri-acetate, which is chlorine tolerant, or TFC/TFM, a thin film composite material which is not chlorine tolerant.
Over time, these membranes will collect enough dirt (foul) to slow down the ability to pass water thus reducing efficiency. This water flow may be a critical part of a water system or part of a manufacturing process, and reduced flow due to blockage will result in a loss of production.
Integra provides reverse osmosis membrane cleaning to restore the membranes to a more efficient level of filtration. We offer a unique process that additionally provides a before and after analysis of the membrane, to illustrate what percentage of filtration flow has been restored and how many
more times the filter may be cleaned before requiring replacements.
This information provides you with better monitoring of your RO system and helps you to budget for replacement membranes in advance.
This benefits you by helping you estimate replacement membranes for the future and reduce downtime repair costs.
Integra also offer CIP cleaning. Clean-in-place (CIP) is a method of cleaning the interior surfaces of pipes, vessels, process equipment, filters and associated fittings without disassembly.
CIP offers fast, repeatable, and effective cleaning without chemical exposure risk to people. This cleaning method is often utilised in industries that require high levels of hygiene such as dairy, beverage, processed foods, pharmaceutical, and cosmetics.
The benefit to industries that use CIP is that the cleaning is faster, less labour-intensive and more repeatable, and poses less of a chemical exposure risk.
