Planning Tool
PAM Solution Preparation and Tank Capacity Calculator
Enter your dry PAM demand, the concentration you plan to prepare, and your batch schedule to estimate water required per batch and the nominal tank size. Results are planning estimates — tank selection must account for actual freeboard, mixer geometry and site standards.
Formulas
c = concentration (%) ÷ 100
solution kg/day = dry PAM kg/day ÷ c
dry PAM kg/batch = dry PAM kg/day ÷ batches/day
solution kg/batch = solution kg/day ÷ batches/day
water kg/batch = solution kg/batch − dry PAM kg/batch
solution L/batch ≈ solution kg/batch ÷ 1.0 (1 kg/L density — planning only)
nominal tank L = solution L/batch ÷ (fill factor ÷ 100)
The 1 kg/L solution density is a planning approximation for early-stage sizing. Actual solution density varies with concentration and polymer type and must be measured for final equipment design.
Your inputs
Enter the concentration you will use — this tool does not recommend a value.
Fraction of tank volume actually usable (e.g. 80 means 80%). Must be greater than 0%.
* Required. All values are entered by you — this tool does not prescribe concentration, batch schedule or fill factor.
Worked example
A plant needs 20 kg dry PAM per day. The operator plans a 0.2% w/w solution, 2 batches per day, with an 80% usable fill factor.
c = 0.2 ÷ 100 = 0.002
solution/day = 20 ÷ 0.002 = 10,000 kg solution/day
dry PAM/batch = 20 ÷ 2 = 10 kg dry PAM/batch
solution/batch = 10,000 ÷ 2 = 5,000 kg
water/batch = 5,000 − 10 = 4,990 kg water/batch
solution L/batch ≈ 5,000 ÷ 1.0 = about 5,000 L solution/batch
nominal tank = 5,000 ÷ 0.80 = 6,250 L nominal tank
The 0.2% concentration in this example is illustrative. Appropriate concentration depends on your PAM grade, feed water and equipment — consult your preparation guide.
Applicability and limits
- The 1 kg/L density is an approximation. Actual density varies with concentration and grade.
- This tool does not prescribe concentration, mixer speed, maturation time, grade or equipment.
- Final tank selection requires freeboard allowance, mixer geometry, foam and site engineering review.
- Results are planning estimates and do not replace engineering design or equipment certification.
