When reverse osmosis element membrane is seriously polluted, the drug cleaning is often referred to as organic chemical cleaning. The actual effect of cleaning will be better. Drug cleaning can remove pollutants and dirt in ro system membrane more quickly, thereby repairing the original characteristics of the membrane.
In some cases, first perform high pH cleaning to remove oil and organic chemical contaminants, and then perform low pH cleaning. Some cleaning water solutions are added with cleaning solutions, which are helpful to eliminate more serious microorganisms and organic chemical residues. Other experimental reagents (such as EDTA (ethylenediaminetetraacetic acid) antioxidants, colloidal solutions, organic compounds, etc.) can be used to remove microbial strains and Potassium thiocyanate scale.
(1). Clean ro system membrane.
Wash with reverse osmosis water or ion exchange water for a few minutes.
(2). Set up medicine washing and cleaning agent.
Make sure that the cleaning agent is completely melted.(3). Loop.
(4). Soaking and recycling.
Slowly close the gate valve at the inlet, and terminate the circulation pump when the circulation speed approaches zero. In order to better prevent the liquid from escaping from the high-pressure container, the relevant valve can be opened during the entire infiltration process. The soaking time depends on the contamination level. Usually 1 to 12 hours. After soaking, open the appropriate valve and circulate.
Use reverse osmosis water or ion exchange to clean membrane for ro water purifier and the cleaner chemicals.
