Cooling-Water Treatment

01 / WHY WATER TREATMENT MATTERS
Stable cooling-water chemistry supports heat transfer and equipment reliability. Evaporation in an open recirculating system concentrates dissolved minerals, while airborne solids and microbial growth add further treatment challenges. A suitable program balances scale, corrosion, deposit and microbiological control with blowdown, filtration and routine monitoring. Closed-loop systems require a separate assessment of metallurgy, water losses and operating conditions.
02 / RISKS OF AN UNSUITABLE PROGRAM
Scale and fouling can insulate heat-transfer surfaces, restrict flow and increase the operating effort needed to maintain cooling duty.
Corrosion may cause metal loss, leakage and equipment deterioration. Biofilm and suspended deposits can worsen fouling and create conditions for localized corrosion.
An unsuitable chemical program or poorly controlled blowdown can increase water use, maintenance and unplanned cleaning. Product choice and application must be reviewed together with actual water chemistry and system operation.
03 / THE HARVEST CHEMICAL PROGRAM
Scale and deposit control — OPTICORR technology is evaluated against the mineral-scaling and fouling potential of the cooling water.
Corrosion management — inhibitor selection is matched to system metallurgy, water characteristics and operating conditions.
Microbiological control — VANICIDE and biodispersant options are assessed as part of the site-specific treatment and monitoring program.
Program review — make-up and circulating-water analyses, cycles of concentration, dosing, blowdown and performance trends guide the treatment plan. Product grades and application parameters are confirmed through technical assessment and relevant product documentation.
04 / START WITH YOUR OPERATING CONDITIONS
Continue to the questionnaire with your cooling-system type, circulation flow, supply and return temperatures, system volume and metallurgy. Describe make-up water, pretreatment, blowdown, current chemicals and monitoring. Include available pH, conductivity, hardness, alkalinity, chloride, silica and microbiological data, with units and sampling points.
