Description

Determine the polyaluminum chloride (PAC) product consumption and dosing flow based on the plant flow rate and the average and maximum doses. The model assumes a commercial PAC with:

• product mass concentration $C = 16%$;
• density of the concentrated product $\rho = 1.34\ \mathrm{kg/L}$.

Determine the polyaluminum chloride (PAC) product consumption and dosing flow

What is calculated

1. Average mass consumption of the product $$ \dot m_{\text{avg}}=\frac{Q\cdot d_{\text{avg}}}{C} $$

2. Average volume consumption of the product $$ \dot V_{\text{avg}}=\frac{\dot m_{\text{avg}}}{\rho\cdot 1000} \qquad(\text{since }1000\ \mathrm{L}=1\ \mathrm{m^3}) $$

3. Volume of solution to be prepared (at the concentration defined by the dilution ratio) $$ V_{\text{solution}}=\frac{\dot V_{\text{avg}}}{\text{dilution ratio}} $$

4. Maximum dosing flow (based on the maximum dose) $$ q_{\max}=\frac{\dot V_{\text{max}}}{\text{dilution ratio}} $$
