In a $500$m$3$ activated sludge basin with $36\%$ w$/$w activated sludge, $5,000$ litres of wastewater per hour arrives. The decomposition of organic matter there results in a sludge gain of $750$ kg$/$h$.$ The

effluent is free of sludge particles as it is obtained by microfiltration of the suspension from the basin. The residual stream after filtration contains $50\%$ w$/$w sludge of which a part is returned to the activated sludge basin and the rest is discharged.

Question : Calculate the flows of the effluent, sluice flow and recycling flow

$->$ Can you provide me a flowchart of the system to understand it better? Thank you
