Makeup-Water Characterization

Set cooling-loop quality and demand basis.

Objectif

Declare the source, seasonal quality envelope, available volume, and end-use requirements that constrain cooling chemistry and water balance.

Prochaine décision

Questions d’ingénierie

What is the makeup source, flow envelope, and seasonal or event-driven variability?
What are pH, conductivity/TDS, hardness, alkalinity, silica, chloride, temperature, turbidity, and relevant residuals?
Is the source reclaimed water, and what treatment history or compatibility limits apply?

Contraintes / considérations de conception

Cooling-water compatibility depends on the actual metallurgy, heat-transfer surfaces, treatment program, operating cycles, and discharge route.
Reclaimed water requires source-specific constituent, residual, and variability review; a source label alone is not a compatibility assessment.

Declared corrosion monitoring basisproject basis

Contraintes / considérations de conception

LSI/RSI are empirical screening indicators based on supplied chemistry; they do not predict metal-specific corrosion, silica behavior, scale deposition rate, or biocide efficacy.
The dosing calculator calculates feed and batch quantities for a selected chemical and dose; it does not select an inhibitor/biocide program or set a cooling-water control strategy.
Sidestream filtration and reclaimed-water compatibility require measured solids/chemistry, metallurgy, vendor, and project review.

Outils pour cette étape

Ouvrir l’outil Disponible Calculateur de Base de Dosage Chimique Supporting: calculate feed and batch quantities after the chemical and dose are selected; it does not choose the program.

Cooling-System Balance

Connect evaporation, cycles, makeup, and blowdown.

Objectif

Connect the declared cooling duty and circulation basis to evaporation, cycles of concentration, drift, blowdown, and makeup demand.

Prochaine décision

Decide how blowdown is controlled, treated, and discharged or reused.

Questions d’ingénierie

What heat-rejection duty, circulating flow, and hot-to-cold water range govern?
What evaporation coefficient, drift class, and target cycles of concentration are justified by site conditions?
What makeup and blowdown flows result, and which measured circulating-water chemistry is used for saturation screening?

Contraintes / considérations de conception

The balance is a screening estimate from declared circulation, range, drift, and cycles; heat rejected is informational and does not size tower hardware or determine circulation from a heat load.
LSI/RSI is calculated only from supplied chemistry and does not establish the allowable cycles for silica, chloride, corrosion, biology, or metallurgy.

Contraintes / considérations de conception

Cooling-water balance can estimate blowdown flow but does not select blowdown treatment or determine reuse/discharge quality.
RO screening requires a characterized feed and defined recovery objective; it does not design pretreatment, sidestream filtration, concentrate handling, or permit compliance.
