Tublar filter for water-treatment and water-treatment filter module comprising thereof

摘要

A tubular filter for water treatment is provided. The tubular filter according to an embodiment of the present invention is a tubular filter through which both ends are penetrated, and the filtration flow is formed from the outside to the inside or from the inside to the outside of the tubular filter, and the first fiber web having different average pore diameters from the outside to the inside. And it is implemented including a filter media layer comprising a second fiber web. According to this, compared to the flat membrane, the effective filtration area is significantly improved, the filtration efficiency is high, but contaminants are not easily collected on the filter surface, backwashing is easy, and stable water flow and performance can be maintained in the long term. In addition, since it has a multi-distributed pore structure, there is an advantage that various products can be implemented according to the purpose of use. In addition, the durability of the filter is extended due to its excellent durability, and as the durability of the filter is maintained even during backwashing, it can be widely applied to the water treatment field.
