Chlorine Concentration Adjustment Calculator for Water
This calculator can be used to adjust the chlorine concentration of water to disinfect it for drinking and also for other applications. Typical levels of free chlorine (or residual chlorine) in drinking water are 0.2 - 2.0 mg/L though levels can be as high as 5 mg/L. Chlorine that is added to water is consumed first to become combined chlorine before it can emerge as free chlorine.
Division of Drinking Water February 2025 Example Calculations of Chlorine Dosage Note: Percent sodium hypochlorite (%NaOCl) is based on weight per volume (w/v) in the equations below. Specific gravity is incorporated as part of the solution strength (% w/v). Equation 1A: Average Dose - Chlorine dosage (mg/L) measured as Cl2:
How to Calculate Chlorine Dose | Sciencing
How to Calculate Chlorine Dose. Water treatment plants convert fresh water into potable drinking water, removing contaminants and killing bacteria that are harmful when ingested. A common method of cleaning the water being processed is with the use of chlorine. When using chlorine in the water it is important to

Example: If a given water source had a chlorine demand of 3 mg/L and you wanted a chlorine residual of .5 mg/L leaving the plant, what would your dose be? Dosage, mg/l = (Demand, mg/l) + (Residual, mg/l) Chlorination –box 2 1. If the chlorine dose added to drinking water equaled 10 mg/L and the chlorine demand
Calculate rate of dose, demand and residual values in a water using this free chlorine dosage calculator tool. Formula: Chlorine Dosage (mg/L) = Demand (mg/L) + Residual (mg/L) Note : Type any two known values for calculation Chlorine Dosage Calculator

CALCULATING THE CHLORINE DOSAGE USING: 5% TO 15% AVAILABLE CHLORINE SODIUM HYPOCHLORITE ( NaOCl ) CALCULATING THE CHLORINE DOSAGE USING: 5% TO 15% AVAILABLE CHLORINE SODIUM HYPOCHLORITE ( NaOCl ) We will modify some of those previous examples and problems that we used with "pure" chlorine by adapting them for disinfection using liquid sodium hypochlorite.
- Why is Polymer-Flooding produced water more difficult to treat for reinjection?
- Polymer-flooding produced water is more difficult to treat for reinjection compared with normal produced water because of the presence of residual hydrolyzed polyacrylamide (HPAM). A novel cathode membrane integrated electro-hybrid ozonation-coagulation (CM-E-HOC) process was proposed for the treatment of polymer-flooding produced water.
- How can low-pressure membranes be used for water treatment?
- Low-pressure membrane processes such as microfiltration and ultrafiltration can remove particulate substances and some fraction of organic compounds, making them suitable for the treatment of produced water ( Liu et al., 2025; Xiong et al., 2016 ).
- Does Cm-E-hoc process achieve in situ self-cleaning in Polymer-Flooding produced water?
- Conclusions The proposed CM-E-HOC process achieved in situ self-cleaning by generated microbubbles in the cathode membrane, which exhibited significantly higher SS and turbidity removal efficiency than the CM-EC process for the treatment of polymer-flooding produced water.
