WATER TREATMENT EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide a water treatment equipment using a hollow fiber membrane module capable of more effectively capturing a fibrous impurity contained in a liquid to be treated and capable of performing a long and stable filtration treatment. SOLUTION: The water treatment equipment 1 according to this invention is provided with the hollow fiber membrane module 10 treating the liquid to be treated, an air diffuser 20 mounted beneath the membrane module 10 and an impurity capturing section 21a to capture the fibrous impurity in the liquid to be treated and mounted between the membrane module 10 and the air diffuser 20. With this constitution, a stable filtration treatment can be performed even by using a water treatment equipment with a conventional hollow fibrous membrane module by preventing the fibrous impurity from twining around the hollow fibrous membrane when capturing the impurity.
