pH Adjustment Calculator for Water Systems

Use this calculator to determine the proper amount of soda ash needed to adjust the pH of your water system. Simply enter your source water pH, target pH, flow rate, and equipment specifications to receive a personalized solution recipe and dosing instructions.

Why pH Adjustment Matters:

Proper pH levels are crucial for water system performance, equipment longevity, and water quality. Incorrect pH can lead to corrosion, scaling, reduced effectiveness of disinfection, and poor water taste. Precise chemical dosing ensures optimal water quality while minimizing chemical usage and costs.

      Understanding pH Adjustment

      Key Factors in pH Adjustment

      • Source Water pH: The starting pH level of your water
      • Target pH: The desired pH level for your water system
      • Flow Rate: The volume of water passing through your system per unit time
      • Alkalinity: Affects how much chemical is needed to change pH

      Benefits of Proper pH Control

      • Equipment Protection: Prevents corrosion and scaling in pipes and equipment
      • Improved Disinfection: Optimizes the effectiveness of chlorine and other disinfectants
      • Better Water Quality: Improves taste, odor, and overall water quality
      • Regulatory Compliance: Helps meet water quality regulations and standards

      About Soda Ash (Sodium Carbonate)

      Soda ash (sodium carbonate, Na₂CO₃) is one of the most common chemicals used to raise the pH of water. It's effective, relatively safe to handle, and economical for most water treatment applications.

      Property Value Notes
      Chemical Formula Na₂CO₃ Sodium Carbonate
      Solubility 30g/100mL At room temperature
      pH of 1% Solution ~11.3 Strongly alkaline
      Typical Dosage 2-5 ppm Per 0.1 pH unit increase
      Safety Classification Irritant Use proper PPE when handling
