Wetlands are natural brine treatment systems. These wetlands rely on naturally occurring processes to improve the water quality. It was found that wetland systems often provided cost-effective, low energy, natural alternatives to energy intensive processes (Kepke, n.d.).
Biological treatment processes can be used to remove organics from brines. Unfortunately the high salinity of the brines makes it difficult to treat it with conventional bacteria cultures (Woolard, 1994).
