Membrane bioreactor (MBR) has emerged as the wastewater treatment technology of choice for an increasing number of municipalities over the last five years. This growth is driven by the very high quality effluent produced by MBR -- exceeding strict standards or ideal for direct reuse -- and is fuelled by a steady reduction in treatment cost resulting from improvements in membrane productivity.

Louisiana contains approximately 40 percent of the coastal wetlands in the United States. These wetlands consist of swamps and both economically and environmentally important freshwater and saltwater marshes. The wetlands support nearly a third of the fish and shellfish yields in the lower 48 states and approximately 40 percent of its fur harvest, while there are more than 200,000 acres of private oyster leases. Also, the wetlands provide a wintering habitat for more than half of the ducks and geese in the Central and Mississippi Flyways.

Whole effluent toxicity (WET) testing has evolved into a critical element of many National Pollutant Discharge Elimination System (NPDES) permits issued to both industrial and municipal dischargers. More than 6,500 dischargers to both fresh and salt waters are required to conduct toxicity tests to determine if their effluent might be potentially toxic to organisms in the receiving system.
