Kaldens MBBR Bio Media


MBBR filter media is a novel biologically active carrier, it adopts scientific formula, depending on the nature of water, blending a variety of beneficial microorganisms grow quickly attached trace elements in polymer materials, through a special process modification, constructed, with more than large surface area, hydrophilic, high biological activity, biofilm fast, good effect, good impact resistance. Special design of surface, stronger bio-film growth capacity; Large specific surface area, high voidage, the more periphyton biomass; Unique design of structure and shape according to hydromechanics, strong three- dimensional flow dynamics in the water; Adding hydrophilic groups and other trace elements, the biofilm formation time only 3-15 days; Excellent impact strength, strong gas shear capacity; Without any holder, easy to cure, save energy and space
