The skeleton, filaments, density, and shape are all important parts of the filter brush. Any error in any part will cause serious errors in the filtering effect, affect the filtering effect, and even secondary pollution. How to tell if a filter brush is good from the bad? How to identify a high-quality filter brush?
The framework of the filter brush should be made of high-quality stainless steel, steel 304 or above, and high-quality stainless steel will not rust and break; the wool is made of high-quality materials such as PET, which is anti-aging, anti-corrosion, high-temperature resistance, high flexibility, and bending recovery Strong strength and elasticity, it can hang the film well; the brush should be twisted tighter and denser so that it is not easy to shed the phenomenon; the bristles are evenly distributed, not more than one side and less than the other, otherwise it will affect the hanging of the biofilm membrane.
Choosing a high-quality filter brush must meet all the above requirements because if one of the requirements is not met, it is unqualified. A qualified filter brush can filter solid debris while hanging biofilms, allowing biochemical bacteria to perform biochemical filtration, which has a dual filtering effect.
