Media Screen for MBBR

The approach of carrier retention sieves is developing on the basis of engineering practice. Early designs used vertically mounted stainless-steel flat-panel sieves. Now horizontally configured stainless-steel wedge-wire sieves are usually used in MBBR applications. When placed horizontally, its position and orientation are favorable for the carrier to scrub the sieves and avoid the blockage of the carrier and waste.

The stainless steel wedge-wire sieve traps the biofilm carrier while allowing the treated wastewater and shed biofilm to flow to the next stage of treatment.

When vertical-mounted flat-panel sieves are used, an air-sparge system should be mounted along the bottom edge of the panels to periodically pulse the sieves and prevent any accumulation of waste.
