Emergency O&M that brought the plant back online without any downtime at the mine.

Challenge

Broken Hill has relied on the Menindee Lakes as the town’s main water supply since the 1960’s. The Menindee Lakes is a chain of shallow ephemeral freshwater lakes connected to the Darling River to form a storage system.

In late 2015, due to the drought conditions in the Darling system the capacity of the lake system was close to empty.

This not only limits supply of water but also impact on the quality of water which deteriorates (salinity increases) due to the high evaporation rate. Under these conditions, Broken Hill’s Water Treatment Plant, designed to remove turbidity and organic matter using conventional filtration process, requires an upgrade with the reverse osmosis process to remove the excess salinity.

Therefore the requirement for an RO plant arose, which required completion in a very short time frame - 12 weeks, very careful installation and integration with the continuously operating upstream water filtration plant, along with numerous procedures and measures to comply with from the NSW Public Works who managed the overall project on behalf of Essential Water, the owner and operator of the Broken Hill WTP.

The new RO plant was required to be integrated with the existing water treatment facility on site - successful integration would require close management of the equipment interfaces.

With a 12 week time frame, the project was completed in a very short time frame to all required standards set out by the NSW Public Works.

Challenge

Osmoflo was engaged as a water partner to process/purify mine-affected water for utilization in their underground coal mine on the state-of-the-art longwall operations. The feed water was changed without prior knowledge, causing irreparable damage to the reverse osmosis membranes in the "Osmoflo" water treatment system.The demand for purified water underground is critical. For the mine to continue operations the membranes needed to be replaced immediately.

Solution

With a sustainable water future required, access to purified water was critical for the mine to continue operating. Fortunately, Osmoflo’s Adelaide Head Office has stock available for emergencies and was able to work with Anglo American to dispatch the 100+ membranes on a “Hot Shot” truck, successfully delivering them 2,220kms in under 24hrs.

Result

With the collaboration and fluidity between Osmoflo and Anglo American, the plant was back online without any downtime at the mine, potentially saving the client millions of dollars.By delivering continuous online monitoring, support and stock, Osmoflo is ensuring the mine can operate successfully now and into the future.
