Design of a hospital laundry effluent clarification system

Approximately 20% of the mineral coal ash (MCA) generated worldwide, during combustion this fossil fuel, has been used to produce Portland cement. Other applications include soil improvement, ceramic industry, catalysis, and an application with special interest for work which is synthesis zeolites. A hospital effluent clarification system was developed using MCA as adsorbent substances responsible color by laundry. perfect mix tank promotes intimate contact between effluent. At exit mixing tank, a pH sensor correlated value variable concentration in mixture inside tank. The information about then sent programmable logical controller (PLC), regulated motor speed screw conveyor, aid frequency inverter. removal efficiency order 99.8% achieved. proposed can operate both batch continuous. In first case, ideal operating conditions be set. strategy adjusting obtain adequate nominal capacity reducing or increasing number cyclones per battery cyclone batteries.
