Ecology: task 0001

Compare the effect of cleaning industrial impurities in a multistage sorption plant (the steps are specified in the assignment). Wastewater flow rate Q, m3 / h; sorbent dose Сс, kg / m3. The initial concentration of the sorbent Cn, kg / m3. The adsorption constant of the distribution of the sorbate between the sorbent and the solution Cads = 8000. The required degree of wastewater treatment in the sorption plant,%.
The data for solving the problem are given in the table.

Cleaning stages: 1 and 4
Wastewater consumption, m3 / h: 18
Sorbent dose, kg / m3: 1,45
Initial concentration of sorbate, kg / m3: 0,27
Required degree of purification,%: 98
