Reverse osmosis membranes can last up to 4 years if the industrial reverse osmosis unit is properly operated and the membranes are cleaned chemically in a timely manner. It is important to follow the cleaning intervals recommended by the manufacturer of the unit.
The need for cleaning also depends on the contamination of the water supply. In any case, the membranes must be cleaned at least once every 6 months.
In order to clean the membranes, in most cases they have to be dismantled. Therefore, the reverse osmosis system is first shut down. The membranes are placed in a chemical washer.
Some reverse osmosis systems allow washing without removing the membranes and using a special unit.
Flushing an industrial reverse osmosis system should be performed by trained professionals. Otherwise, there is a good chance that the membranes will fail.
STEPS OF CLEANING
MEMBRANES ARE CLEANED IN THREE STAGES:
- Acid wash to remove carbonate deposits and compounds of aluminum, iron, manganese;
- Alkaline washing to remove organic compounds and sludge deposits;
- biocide flushing to prevent biofouling.
Washing cycles are selected depending on the type of deposits and the degree of contamination of the membranes.
When washing with acid and alkaline solutions, it is necessary to control the temperature and pH level. Reverse osmosis membranes should be washed at a high flow rate of the cleaning solution and low pressure.
It is important to use professional cleaning agents. Special reagents do not damage the membranes if used in safe concentrations. The contact time of the reagent with the membrane should also be considered. Professional equipment for chemical washing of reverse osmosis membranes is resistant to reagents.
Company "Akvarum" is engaged in servicing reverse osmosis systems in Odessa and the region, as well as throughout Ukraine. We use professional equipment and reagents for washing the membranes. We also offer:
- setting controllers of reverse osmosis systems;
- membrane replacement;
- cartridge replacement;
- resin replacement.
