Description

Initial Rainwater Filtration Device For Rainwater Reuse The present invention relates to an initial rainwater filtration device for rainwater reuse, and more specifically, to an initial rainwater filtration device for rainwater reuse that allows collected rainwater to be collected in a rainwater storage tank after foreign substances have been removed and the collected rainwater has been sterilized. [Project ID] E2424010 [Ministry Name] Gyeonggi-do [Specialized Research Management Agency] Gyeonggi Economic & Science Promotion Agency [Project Name] 2024 Gyeonggi-do Materials, Parts, and Equipment Enterprise Development Support Program [Research Project Title] Initial Rainwater Filtration Device for Excellent Rainwater Reuse [Organizing Agency] GC Tech Co., Ltd. [Research Period] June 3, 2024 – November 29, 2024 Stormwater treatment facilities are being mandated for comprehensive sports complexes, indoor gymnasiums, public offices, schools, apartment complexes, golf courses, etc., exceeding a certain size. Typically, a stormwater treatment facility consists of an initial stormwater filtration device for physically removing pollutants; a stormwater storage tank; filters for controlling sterilization, turbidity, BOD, odor, hydrogen ion concentration (pH), color, etc.; and a treatment tank. However, since rainwater is mixed with external pollutants such as fallen leaves, plastic, various types of trash, and floating debris, a filtration device must be installed to make the rainwater usable. Previously, these filtration devices used plate screens to filter out contaminants and foreign substances, but there was a problem where, as the amount of contaminants and foreign substances increased, the screen would become clogged, and as a result, rainwater could not be collected. To improve this, it became possible to stably collect rainwater by using the initial rainwater filtration device of Korean Registered Patent No. 10-2398472, which removes foreign substances filtered by the screen. Considering the ability to secure good rainwater quality in the case of such existing stormwater treatment facilities, water quality standards are recommended to ensure the removal of aesthetically affecting substances (pH, turbidity) and microbiological stability (total coliforms). In the case of total coliforms, it is recommended that they not be detected in water that may come into contact with the human body (e.g., fountain water, water for preventing airborne dust, landscaping water, etc.). Existing facilities do not have disinfection facilities to remove total coliforms, or they have separate disinfection facilities using hypochlorous acid or ultraviolet lamps. Due to the nature of rainwater treatment facilities, which must be installed in a confined area, these facilities have the problem of using unnecessary space.
