Activated Sludge Bioreactor (ASBR)
Mining
Midwest Region, Western Australia
BACKGROUND
The largest copper producer in Western Australia needed to replace their existing containerised sewage treatment plant as it was badly corroded and had deteriorated beyond economic repair.
Whilst the existing plant was only 5 years old the external structure was badly corroded and the client was concerned that there would be a major failure. The material selection for the biological tank was the main issue where mild steel with only a standard paint specification was used, but as sewage is highly corrosive this had not stood the test of time. MAK Water’s 15 year design life using FRP tanks was selected to provide a complete design, manufacture and installation package for the replacement sewage treatment plant.
MAK Water worked closely with the client to design a fit for purpose, long term solution that met the required treated effluent quality.
SOLUTION
Modular Activated Sludge Bioreactor (ASBR) plant to treat 50
m3 per day of domestic strength sewage to Class C Recycled
Water for onsite reuse via irrigation.
