Wastewater DAF & pH Correction

Hydro International successfully completed the Design and Installation of a Dissolved Air Floatation unit complete with pH correction and coil pipe flocculator for the addition of Coagulant and Flocculant.

The installation included the supply of a bunded chemical storage unit and Hydro Emulsion Polymer make up unit. The proposed solution successfully reduced the TSS to less than 100mg/l and  less than 1 PPM of insoluable Copper ( Cu) on the discharge. The sludge generated from the DAF is stored in a 30m3 stainless steel hopper bottomed vessel complete with side mounted external mixer for ease of maintenance.

Integration of existing feed pumps and controls were undertaken and the unit is controlled with a dedicated MCC located adjacent to the DAF and is controlled with Allen Bradley HMI and Hardware. The panel is housed within a GRP kiosk to allow the operator observe and control items locally in addition to this the complete system is also linked to the current BMS for remote monitoring and trending.
