We would like to introduce the installation of "PPP-240" at a special nursing home in Chikusei City, Ibaraki Prefecture. The construction took place in an area without sewage and no discharge outlet, and they requested a system capable of processing 57,000 liters per day for the special nursing home. Thus, we introduced the "PPP-240," which can handle a maximum of 57 tons of wastewater. As a result, instead of starting from scratch to create wastewater facilities, the introduction of our product allowed for the simultaneous creation of an individual wastewater treatment facility, eliminating the problem. This also led to a reduction in construction time and budget. **Background for the Introduction** - No sewage on the premises and no discharge outlet - Request for a system capable of processing 57,000 liters per day for the special nursing home - Construction period: 4 days - Number of workers: 4-5 people *For more details, please refer to the PDF document or feel free to contact us.*

We would like to introduce the construction results of the convenience store renovation project (Tochigi Prefecture) where "PPP-30" was implemented. In a location without a drainage outlet, "PPP-30" was introduced for the construction of the convenience store due to the absence of sewage treatment. After the construction, it became possible to process wastewater for 30 people, enabling a treatment capacity of 15 tons per day. Additionally, this led to a reduction in construction time and budget. 【Background Leading to Implementation】 - There was no sewage treatment in a location without a drainage outlet when constructing the convenience store. - Construction period: 3 days - Number of workers: 3 *For more details, please refer to the PDF document or feel free to contact us.

• Water Treatment

PPP (Sleepy) is a device that allows the evaporation and diffusion of treated wastewater on sites without sewage systems, where even if a septic tank is installed, there is no outlet for discharge. It consists of a super high-density polyethylene container with a diameter of 600 mm and a height of 900 mm, along with a high-void crushed stone filling layer. Processing Steps: The treated wastewater from the combined septic tank is sprayed from the top of the treatment device, where a scum removal net adsorbs impurities, and a carrier sponge performs adsorption and filtration of suspended solids (SS), followed by decomposition by microorganisms. By installing a waterproof sheet at the bottom of the treatment layer, the treated water is stored in the high-void crushed stone layer and gradually diffuses into the soil from the walls of the treatment layer, ultimately evaporating into the atmosphere. To ensure that the water quality is conducive to easy diffusion into the soil within the treatment device, stable functionality is maintained. PPP (Sleepy) has been installed in Tochigi Prefecture, Ibaraki Prefecture, Gunma Prefecture, Chiba Prefecture, Yamagata Prefecture, Shizuoka Prefecture, Miyagi Prefecture, Kanagawa Prefecture, Aichi Prefecture, Kumamoto Prefecture, and others.
