RO & Membrane Care
01 / WHY WATER TREATMENT MATTERS
Reliable reverse-osmosis performance depends on the quality of the feedwater and the way the membrane system is operated. Pretreatment, antiscalant selection and cleaning must be considered together with membrane type, recovery and operating conditions. A membrane-care program aims to manage scaling and fouling while protecting membrane integrity. Reviewing normalized performance trends helps distinguish changing feedwater conditions from a developing treatment or equipment problem.
02 / RISKS OF AN UNSUITABLE PROGRAM
Mineral scale, colloids, organic deposits and biofouling can reduce permeate production and increase differential pressure or energy demand.
Poorly selected cleaning chemistry or unsuitable pH, temperature and exposure conditions can damage membranes or leave deposits incompletely removed. Oxidant exposure must be controlled according to the membrane manufacturer’s requirements.
Selecting an antiscalant without reviewing feedwater chemistry and recovery can leave important scaling risks untreated. Cleaning alone does not correct an unresolved pretreatment or operating problem.
03 / THE HARVEST CHEMICAL PROGRAM
Scale control — SCAFFIX antiscalant options are assessed against feedwater analyses, concentration conditions and the membrane system’s operating requirements.
Membrane cleaning — Harvest ROC 2240, ROC 2260 and ROC 2280 provide cleaning options for different deposit challenges. Selection follows foulant identification and review of the applicable product documentation.
Cleaning strategy — the chemical sequence and application conditions are established for the deposit type and membrane manufacturer’s compatibility limits.
Program review — pretreatment, antiscalant dosing, dechlorination where required, cleaning history and normalized performance trends are reviewed together before recommendations are finalized.
04 / START WITH YOUR OPERATING CONDITIONS
Continue to the questionnaire with membrane make and model, system capacity, feed flow, recovery, operating pressure and differential pressure. Describe the feedwater source, pretreatment, oxidant control, current chemicals and CIP history. Include available feed and permeate analyses, turbidity or SDI, and performance trends, with units and sampling points.
