40 ft containerised plant at up to 30 m3/h reduced oil from 100+ ppm to 0 to 2 ppm and TSS from 500 to below 5 ppm for Department of Health reuse.
Client: joint venture of two international gold producers.
Duty: up to 30 m3/h (720 kL/day), average 650 kL/day of HV and LV wash bay water with surfactants, emulsified hydraulic and engine oils and refuelling spikes up to 30,000 ppm. Existing plate separator could not meet reuse standard.
Plant: 40 ft containerised Wash Water Treatment System (12 m x 2.5 m), four stages: MyCelx Advanced Coalescer, two MXR regenerable vessels, MyCelx cartridge filters, then AOP sanitation for Department of Health reuse in a hot climate; PLC-controlled automatic backwash.
Results: oil 100+ ppm to 0 to 2 ppm, suspended solids 400 to 500 ppm to below 5 ppm, Legionella and E. coli below 1 CFU/100 mL, sheen and odour free. The mine's RO was not upgraded; RO water was redirected to processing.
