With development of old filtration methods and their evolution to membrane processes, using of semipermeable membranes in waste water treatment industries has been increases significantly, so that with combination of ordinary biotreatment processes with membranes, new methods have been developed. Sizes of these filters are in the range of 0.02-0.08 micrometer and ordinary settling tanks, disinfection and filtration have been replaced with combined processes. This combined biologic process is known as MBR.

Most important applications of MBR method are using of treated effluent in large buildings, in-house waste water treatment in low people societies and treatment of industrial effluent.

MBR advantages are:

1- Larger volumetric loading less hydraulic residence time at the reactor(4-8 hr)

2- Increasing of cellular residence time and producing less sludge

3- Operation in the case of low DO and possibility of simultaneous nitrification and denitrification

4- Highest quality of treated waste water in turbidity, bacteria, TSS and BOD

5- Lower required area due to elimination of settling tank, chlorination, and all filtration steps and decreasing aeration tank.

6- Possibility of upgrading of in-use active sludge plants 

The complex engineering company with experienced, brilliant academic and administrative records at the national level and certification requirements, has ISO 9001-2008 certification the concept of water treatment, pumping stations and water hammer phenomenon and other related services needed by the water industry, ready providing services.

Experts and technical staff of the company with several years experience in the field of education, design, supervision, operation, development and implementation of wastewater projects and industrial projects based on the latest methods and standards in the world as a collection of academic and administrative, are ready to provide services.

reuse of wastewater. In most countries that face water shortages due to wastewater rich in plant nutrients, inexpensive and accessible source of water for irrigation is considered. Wastewater reuse is one of the solutions to water shortages and prevent environmental pollution, especially in arid and semi-arid area. reduce wastewater.
In order to reuse the treated wastewater sanitation, especially in industries as process water, the only way which can guarantee the desired quality, as well as other technical, membrane bioreactor is.

MBR wastewater treatment system, known as an excellent effluent quality without the need for chlorination, suitable for use in irrigation of green spaces without the health and environmental concerns. In addition to the distinctive quality effluent wastewater treatment compared to other methods this method, it is also very less space than other methods.
