This article explains the treatment objective, the design information that matters and the operating checks that help keep the system practical after installation.
Watch pressure, flow and conductivity
Changes in differential pressure, permeate flow or salt passage can indicate fouling, scaling or other operational issues.
Cleaning chemistry must match the foulant
Acidic, alkaline and specialty cleaners are used for different deposits. Membrane supplier guidance and system materials must be considered.
Do not use cleaning to hide a pretreatment problem
Frequent cleaning may indicate inadequate pretreatment, excessive recovery, poor dosing or feed-water changes that should be corrected at the source.
Need a treatment recommendation for your water?
Send the water source, intended use, approximate demand and any available test report. Waterwise Bangladesh can review the requirement and discuss an appropriate treatment approach.
