What is the log removal efficiency of Micro Filtration?

Microfiltration is a filtration process that utilizes membranes with pore sizes typically ranging from 0.1 to 10 micrometers. This technology is highly effective in removing suspended solids, bacteria, and some larger viruses from water. The log removal efficiency indicates how well a treatment method can reduce the concentration of a contaminant in water, with each log reduction corresponding to a tenfold decrease in concentration.

In the case of microfiltration, it is considered to achieve a log removal efficiency of 99.99%, meaning that it can remove 99.99% of the targeted microorganisms and particles. This high level of efficiency is particularly useful in applications such as pretreatment for reverse osmosis or in producing high-quality water for various purposes, including drinking water and industrial processes.

The other options reflect varying levels of efficiency but do not capture the typical performance range of microfiltration. A removal efficiency of 90% would indicate a lower filtration performance, while 99% suggests significant but still not as comprehensive removal. The 99.9% option indicates a good level of efficacy, but it is less than what microfiltration can achieve under optimal conditions.
