11.2 Building Functions and Process Systems
11.2.1 Waste Treatment Building Functions
The WTB will house the following waste treatment and conditioning systems. Where possible
the systems will be designed as individual (e.g. skid mounted) modules that can be relatively
easily exchanged or replaced during the operation of the plant as waste treatment technology
develops. The treatment and conditioning systems that will be incorporated into the WTB have
been described in detail earlier in this report. In addition to treatment and conditioning of waste,
the WTB will also incorporate buffer storage, additional waste management functions and
various auxiliary systems. These functions are described below.
Buffer Storage will include:
· Buffer tanks for liquid effluent awaiting treatment;
· Buffer tanks for concentrates awaiting conditioning;
· Buffer tanks for treated water destined for discharge;
· Buffer areas for raw solid waste;
· Buffer areas for treated solid waste prior to conditioning;
· Buffer areas for conditioned wastes prior to transfer on-site and shipment off-site.
