Antiscalant Dosing Calculator for Reverse Osmosis (RO) Systems

Calculate Your Antiscalant Dosing Rate

m³/hr
Enter the flow rate of water entering your Reverse Osmosis system.
ppm (mg/L)
Desired concentration of antiscalant in the feed water.
%
Percentage of active ingredient in your commercial antiscalant product (e.g., enter 20 for 20% active).
unitless
Specific gravity of your antiscalant product (typical range: 1.05 to 1.30).

Prevent costly membrane scaling and optimize your Reverse Osmosis (RO) system's performance with our Antiscalant Dosing Calculator. Accurately determine the ideal antiscalant dosage based on your feed water flow, target concentration, and product specifications. Ensure efficient water treatment, extend RO membrane lifespan, and reduce operational costs by applying the correct antiscalant dose every time.

Formula:

The Antiscalant Dosing Rate is calculated using the following formula:

Dosing Rate (L/hr) = (Qfeed × Ctarget) / (Cproduct_active × SG × 10)

  • Dosing Rate (L/hr): The required antiscalant dosing rate in liters per hour.
  • Qfeed: Feed Water Flow Rate (m³/hr) - The flow rate of water entering the RO system.
  • Ctarget: Target Antiscalant Dosage (ppm or mg/L) - The desired concentration of antiscalant in the feed water.
  • Cproduct_active: Antiscalant Active Concentration in Product (%) - The percentage of active ingredient in the commercial antiscalant product (e.g., 20 for 20%).
  • SG: Antiscalant Product Specific Gravity (unitless) - The specific gravity of the commercial antiscalant product (e.g., 1.15).
  • 10: A conversion factor to ensure correct units.
