Filtration apparatus
First Claim
1. A filtration apparatus comprising:
- a tank for housing a fluid containing removables, a filter apparatus for filtering the fluid, an air diffuser located under the filter apparatus and generating air bubbles inside the fluid, an air pump for supplying gas via an air pipe connected to the air diffuser, wherein the air pipe is provided with an adjustment valve regulated in advance so that a predetermined amount of gas is caused to pass therethrough, and a stop valve for blocking or releasing the gas that passes through the air pipe.

Abstract
A filtration apparatus is provided which is easy to maintain, manage and which enables preservation of filtration characteristics due to the fact that filtration is carried out by use of a gelatinous filter apparatus. In the filtration apparatus, filtration characteristics can be maintained by providing a bubble supplying mechanism for removing a sedimentary layer comprising removables that is formed on a surface of a filtration film and a filtration characteristics restoring mechanism for restoring the filter film clogged by the removables by causing a back-flow of filtered water accumulated in a cistern. Filtration apparatus maintenance and management are facilitated by improving recovery efficiency of the precipitated removables by tapering a lower part inside a raw water tank and providing a recovery tank for recovering removables via a valve.
