68. Before using river water in production, it is clarified, for which various electrolytes can be used that cause coagulation of silt particles. Calculate the consumption of electrolyte - coagulator (kg / day), if the water consumption at the enterprise is 100,000 m3 / day, and the sign of the charge of suspended particles of sludge is positive:
The coagulation threshold for NaNO3 is 48 mol/m3. What will be the electrolyte consumption when replacing NaNO3 with K2CrO4?
