Anaerbic treatment of industrial effluents

Methanization, an anaerobic biological effluent purification technology that first appeared on the industrial scene in the 1970s, has had great difficulty in developing in France, whereas it has been booming in many European and American countries. It has developed exceptionally well in countries such as Brazil, and is booming in South-East Asia, particularly China.

In France, this technology suffered from a belated awareness on the part of many manufacturers, and was the subject of a significant number of counter-references which hampered its development in the 1980s-1990s. It is still the subject of preconceived and misconceived ideas, and many teachers and specifiers know little or nothing about it.

In recent years, major French manufacturers and industries have rallied around this once neglected technology. Today's energy problems are driving a craze for this purification method. So much so that some manufacturers are ready to collect organic waste from other manufacturers to produce energy.

The two main features of wastewater methanization are the production of methane-rich biogas and a considerable reduction in the production of excess biological sludge. This technology is ideally suited to the treatment of industrial wastewater. What's more, anaerobic digestion is a technology that fits in perfectly with the sustainable development approach. It enables the production of green energy - biogas - from organic pollution.
