Installation structure of larvae filtering device in fluid { INSTALLING STRUCTURE OF LARVA FILTERING APPARATUS }

The present invention relates to a structure for installing a larva filtration device in a fluid, and in particular, to a structure for installing a larva filtration device in a water channel to effectively capture larvae contained in a fluid (water) moving through a water channel.

When larvae (cutworms) are introduced into purification ponds during the water treatment process at a water purification plant or water intake plant, many difficulties arise in water quality management.

In particular, in the summer, it causes substances that cause tastes or odors in tap water, causing significant inconvenience to consumers in using water, causing many difficulties in operation and customer management.

In order to solve this problem, a fixed filter net is currently installed at the outflow of the sedimentation pond to block the inflow of larvae. However, the installed filter net is clogged in a short period of time due to suspended solids in the sediment, so it cannot perform its function properly. In addition, the effectiveness of operating a fixed filter network itself is greatly reduced due to the disadvantage of having to freely replace the filter.

In addition, such a filter device, that is, a filtration device, is installed in a waterway, and at this time, larvae, etc., are often introduced through the gap between the waterway and the filtration device.
