Define the separator endpoint
Gravity clarification rewards settling velocity and compact sludge; DAF depends on bubble attachment, float stability and skimmability. One feed can therefore need a different product or contact history in each separator.
Record coagulant, pH correction, rapid mix, flocculation time, hydraulic load, recycle ratio and target effluent measurement.
Place inversion before process mixing
The emulsion must be activated before it reaches the feed. Confirm the prepared solution is homogeneous, then map its injection point relative to coagulant contact, pumps, air release and the separator.
Measure turbidity or suspended solids beside settling or flotation behavior. Avoid choosing a jar that looks attractive but releases fines downstream.
Scale one variable at a time
Bracket the expected active dose, allow for the hydraulic delay and hold the separator inventory stable before comparing outlet samples. Record changes in feed or recycle during every trial period.
Send flow, water analysis, current chemistry, separator design, storage constraints and expected monthly use with the RFQ.
