Method of manufacture of tubular inertial filter

摘要

A porous isopermeable tubular inertial filter with a large pore size has a slurry of fine particles flowed through it while an effluent is withdrawn through a jacket disposed about it until a thin inner layer of pores become clogged by the fine particles. The filter is then dried and the fine particles sintered in place to provide an inertial tubular filter with a upstream inner surface having a thin layer providing a high degree of filtration supported by the larger pore tubular filter.
