Effluent Treatment Plant / Chemical Dosing

Our Effluent Treament Plants (ETP) are designed to treat waste rinse water from a pickling process at a rate of 10m3/h (large enough for up to four Cylinder Pickling Machines). The ETP is programmed to meet your current discharge limits as required for your region / country.

A control panel with HMI and PLC (Schneider) monitors and controls the process and allows any Alarms to be sent out via e-mail and SMS. Daily/weekly/monthly reporting is available.

Principals of Operation 

The effluent is collected in a buffer tank fitted with a radar level controller, an external level indicator, safety overfill sensor and air agitation controller.

Dual pumps  this effluent to a neutralisation vessel under the monitoring of a full bore magflo. pH is monitored and adjusted with chemical dosing and the neutralised effluent (pH ~ 10.5) overflows into the flocculation vessel where a polyelectrolyte is be added volumetrically. 

The flocculated effluent then overflows into a settlement tank. Sludge from this tank is transferred to a storage tank and susbsequently  pumped to a filter press.  

Clarified water from the settlement tank is pumped to drain.

 OPTIONAL: Grey water recycle:  Recover up to 75% of clarified water for re-use.
