Membrane Cleaning Unit (CIP)

if you want to have continuously same performance, efficiency and long membrane life time for reverse osmosis system in your water treatment plant you must provide periodically membrane cleaning according to data sheets. Otherwise you shall have irreversible damage in your membranes.
 
The membrane in reverse osmosis elements can become fouled by mineral scale, biological matter, colloidal particles and insoluble organic constituents in normal operation. Scales build up on the membrane surfaces during operation until they cause loss in normalized permeate flow, loss of normalized salt rejection, or both. 
 
Elements should be cleaned when one or more of the below mentioned parameters are applicable: 
• The normalized permeate flow drops 10% 
• The normalized salt passage increases 5 - 10% 
• The normalized pressure drop (feed pressure minus concentrate pressure) increases 10 - 15% 
 
enki design membrane cleaning according to custom requirement and specific application.
