Waste water treatment
Biological wastewater treatment
Biological wastewater treatment processes are primarily designed for the removal of dissolved and suspended organic matter from wastewaters. The environmental conditions are optimised to encourage growth of the micro-organisms which use the organic compounds as substrate.
Biological wastewater treatment is also capable of removing other wastewater components, including suspended solids, nitrogen, phosphorus, heavy metals and xenobiotics.
In general the biological wastewater treatment is the most efficient and economic way of removing organic pollution from a wastewater.
The Membrane Bioreactor or MBR is based on the conventional wastewater process, but the separation of micro-organisms is performed by filtration with membranes.

Moving bed biofilm reactor (MBBR) offers an economical solution for wastewater treatment if the "bulk" of the pollution load must be disposed of (as means of cost reduction) or if applicable discharge regulations are not as strict.
