Abstract

PURPOSE: Two multilayer filter devices containing large swelled shale grains as main filter material are connected in series, into which treating water from aerobic bath is introduced, thereby providing miscellaneous-quality water.
CONSTITUTION: A filter device I contains filter layers of gravel 2, fine gravel 3, swelled shale light weight filter material 4 (main filter), and synthetic resin filter material 5 on top of the bottom water collector 1. A second filter device II contains filter layers of gravel 2, fine gravel 3, large gravel 3', silica sand filter 6, swelled shale light weight filter 4 (main filter), and synthetic resin filter material 5 on top of the bottom water collector 1. The second filter device is further provided with chemical feeder pipes 7, 7'. These two filter devices are connected in series, and if required, ozone treatment device is provided downstream.
