Lamella Clarifier (LC), Seawater Reverse Osmosis (SWRO)
Mining
Goldfields-Esperance Region, Western Australia
BACKGROUND
The owner of a nickel mine in the Fraser Range area of Western Australia required assistance with upgrade of the existing water infrastructure to provide a more reliable supply for both potable water and process water to the accommodation village, mine site facilities and process plant. The bore water feed to the Reverse Osmosis (RO) plants had deteriorated considerably causing membrane fouling, equipment damage, high service costs and ongoing plant downtime.
MAK Water was engaged by the owner to provide a quick solution to fix the problem and ensure a more reliable water supply to the site. This included long term hire of multiple water treatment plants and an Operations Agreement to provide plant operators to maintain and operate all of the water treatment plants onsite.
The Operations Agreement is for the provision of plant operation, technical support, onsite maintenance (both planned and emergency), and the supply of consumables required for normal plant operation.
