The plant, which was built on a green field site, is designed to accept a variety
of aqueous industrial wastes for treatment and disposal. It includes a transfer
station for bulking of wastes for treatment elsewhere.
Process feasibility studies, outline process design and equipment
The plant consists of a tank farm for the storage of incoming
liquid wastes, batch reactors for neutralisation of acidic or
alkaline wastes, sludge dewatering and sewer discharge.
The equipment scope includes storage tanks for various categories
of wastes, transfer pumps, two batch neutralisation reactors
and chemical handling and dosing control equipment.
Following neutralisation and settlement the supernatant is further
treated by sulphide precipitation and filtration for removal
of heavy metals to meet the sewer discharge consent. The treated
waste stream is monitored prior to discharge. Sludge dewatering
is by filter presses and cake is removed from site for disposal
A controlled drum storage and transfer station for bulking of solvents
is also included on the site.
