Coagulation Treatment Plant


Flowrate and Chemical Dosing

The coagulation treatment plant has a flowrate of 0.044 m3/s and is dosing alum at a concentration of 25.0 mg/L. No other chemicals are being added to the water.

Suspended Solids Concentrations

The raw water suspended solids concentration is 8 mg/L and the effluent suspended solids concentration is 3.0 mg/L.

Total Mass of Alkalinity Consumed

The coagulation process consumes alkalinity, which is a measure of the water's ability to neutralize acids. The total mass of alkalinity consumed can be calculated by multiplying the flowrate by the change in alkalinity between the raw water and effluent. However, the alkalinity values are not provided in the question, so we cannot calculate the total mass of alkalinity consumed.

Total Mass of Dry Solids Removed

The coagulation process removes suspended solids from the water, which can be measured as the total mass of dry solids removed per day. Dry solids are the solids left behind after the water has evaporated. The total mass of dry solids removed can be calculated using the following formula:

Total mass of dry solids removed = flowrate x (raw water suspended solids concentration - effluent suspended solids concentration) x 24 hours

Substituting the given values into the formula, we get:

Total mass of dry solids removed = 0.044 m3/s x (8 mg/L - 3.0 mg/L) x 24 hours
Total mass of dry solids removed = 2.64 kg/day

Therefore, the coagulation treatment plant removes a total mass of 2.64 kg of dry solids per day from the water.
