Ulan Coal Mines Limited (UCML, the Principal) operates the Ulan Mine located near Mudgee in NSW. The mine includes underground and open cut operations. This requires the extraction of large volumes of water. The on-site water treatment facilities need to be able to produce sufficient permeate to blend with other on-site waters to generate up to 30 ML/d of blended water of suitable quality for environmental river discharge.
A reverse osmosis (RO) plant and Ultra-Filtration (UF) pre-treatment system provided by Osmoflo currently treats water from East Pit, which is a large capacity surface dam. This enables the water to be recycled back into the ecosystem along with on-site irrigation.
