The Brine Pond Problem
Brine is a by-product of coal seam gas production. Historically it is stored in massive brine ponds to evaporate and allowing sludge to be disposed of. However, this method has proven ineffective, creating an ongoing concern for operator. Large bodies of naturally salty fluids (brine) are subject to the ‘Lake Effect’, which shows that the larger a body of water, the less effective evaporation becomes. Salt then creates a crust over the surface, further reducing evaporation and resulting in very large dams of stagnant fluid remaining unchanged indefinitely. The SEMS solution seeks to solve this problem.
The SEMS Solution
Concept’s SEMS utilises the patented Classic Tank, a pre-stressed modular concrete structure taking up a third the area of a brine pond.
In addition, the 3-metre-high walls exclude ground animals from accessing the brine, protecting against poisoning and damage to liners.
The Classic Tank features double-lined leak detection and 24-hour monitoring. In the event that the primary liner breaches, remote operators are immediately notified. The secondary liner then acts as a ‘closed loop,’ safeguarding the environment from contamination.
