B&F Cleartec® is a technology used to increase biological treatment capacity in sewage treatment plants and industrial effluents.

Absolutely innovative, B&F Cleartec® can make it possible to increase up to 100% of treatment capacity without the need to carry out civil works.

Cleartec® is a structure with textile media made of polypropylene to increase and fix the number of microorganisms. It has a broad, rough and highly structured surface, ideal for colonization, providing greater biofilm protection.

Aeration is only necessary for the supply of oxygen to the biomass, and not necessarily for greater mixing as in some MBBR processes.

The textile medium is attached to a stainless steel structure which can be mounted on existing or non-existing aeration systems. The biological stability and the outstanding performance of the system are associated with reconciling the characteristics and advantages of the fixed and mobile bed in a single set.
