STP RECYCLED WATER SYSTEM STAGE 2, WOLLONGONG

PROJECT DESCRIPTION:

Design, procurement, civil construction, mechanical and electrical installation and commissioning of a new recycled water treatment system. Quality of the tertiary filtered effluent is enhanced by chemical dosing, UV treatment and Chlorine contact tanks. Scope included detail design, commissioning and supply/installation all civil, mechanical, electrical, control systems and software.

The system supplies high quality recycled water that replaces approximately 1.4 Million litres per day of potable which had previously been used. Recycled water is now reticulated to Port Kembla Coal Terminal, Wollongong Golf Course and Wollongong City Council sports fields.

Complex Challenges:

The overall treatment system uses several processing elements requiring an integrated control system, incorporating sensors to detect when instruments in elements of the system lose calibration and raise appropriate alarms.

An important safety and maintenance concern was that the covers for the Chlorine contact tanks should be light and easily removable.
