We would like to introduce a case of chemical cleaning of the filtration piping for an outdoor hot spring bath that we undertook. At a certain facility's outdoor bath, there was almost no dirt from hot spring scale this time, so we performed the cleaning using only hydrogen peroxide. Since the work was done right after the busy season, it was somewhat dirty. We lowered the water level to circulate, added chemicals, and discharged grease and biofilm. The work proceeded smoothly as usual. *For more details, please refer to the related links or feel free to contact us.

We would like to introduce a case of high-pressure cleaning of kitchen drainage pipes that we undertook. We went to perform high-pressure cleaning because a certain bakery's drainage was clogged. We started cleaning from the grease trap, but very little dirt came out, which seemed strange. Upon investigating the surroundings, we found an exposed drainage pipe outside, and when we removed the cap, we saw an overflow of sludge. We continued cleaning until the turbidity was cleared. For some reason, it was connected directly to the main pipe beyond the grease trap, bypassing it. *For more details, please refer to the related links or feel free to contact us.*

We would like to introduce a case of temperature sensor and temperature controller replacement that we handled. Due to a malfunction of the temperature sensor, the digital temperature controller was outputting abnormal values, causing the filtration pump to stop due to an error. It was likely that the sensor was faulty, but since the temperature controller was also an old model, we replaced both at the same time. The sensor was equipped with a cover. Finally, we completed the process by making detailed temperature control settings from the PC. *For more details, please refer to the related links or feel free to contact us.*

We would like to introduce a case of a sewage pipe inspection and high-pressure cleaning work that we undertook. We were called to a ryokan (Japanese inn) because the toilet in a special room was not flushing. After investigating the system, we inserted an endoscope. In addition to foreign objects, we were able to confirm the presence of something that resembled fabric and a type of paper that is difficult to dissolve. We applied high-pressure cleaning to remove the foreign objects. After inserting the camera again, it appeared that there was likely an invert between the PVC pipes. We understood that tree roots had invaded from there, causing waste to become clogged. *For more details, please refer to the related links or feel free to contact us.*

We would like to introduce a case of our company's hot spring pipe chemical cleaning (hot spring scale removal). We received a request to clean a hot spring pipe system that had not been used for a while at a source in Atami. Considering the distance and the undulating terrain this time, we decided not to set up a circulation system. Instead, we pressurized the chemicals from the higher facility side, allowed them to soak, and then collected them from the source side. A bypass for collection was installed on the source side, which was opened after soaking with the chemicals. Thin scales often detach easily and can cause blockages due to bends. Finally, we conducted a water flow test to confirm the water volume, and the process was completed. *For more details, please refer to the related links or feel free to contact us.*

We would like to introduce a case of chemical cleaning of the filtration and circulation piping for the large hot spring bath (hot spring, bathing, and legionella measures) that we have undertaken. This facility also regularly uses a filtration circulation system utilizing hot spring water. By using our own two-component cleaning agent, we can simultaneously address legionella prevention and hot spring scale prevention, making it highly recommended for facilities with filters in their hot spring baths. Since it is in an unseen area, maintenance can be difficult to manage, so it is reassuring to request the services of a specialized contractor like ours. *For more details, please refer to the related links or feel free to contact us.

We would like to introduce a case of chemical cleaning of the hot spring bathing facility's filtration circulation piping (removal of hot spring scale, Legionella bacteria, and cleaning) that we undertook. After introducing our cleaning agent and operating the jet piping, dirt is gradually expelled. Depending on the mineral composition of the hot spring (such as iron oxide, calcium, manganese, etc.), the dirt can become scaled. Not only the piping but also the filtration sand inside the filter becomes quite dirty, so if regular cleaning and media replacement are not performed, it will pose unseen risks from a hygiene management perspective. It is necessary to regularly clean to minimize risks to the lowest possible level. *For more details, please refer to the related links or feel free to contact us.

We would like to introduce a case of scale removal and Legionella measures (pipe cleaning, disinfection, and washing) for hot spring bathing facilities that we have undertaken. The way dirt is discharged varies slightly depending on the chemicals used for scale treatment and those used for biofilm treatment. It is necessary not only to add chemicals but also to adjust them to prevent gas locking, and to carry out decomposition and neutralization processes while checking the concentration to safely discharge wastewater. Additionally, the chemicals used are often toxic and hazardous, so caution is required during use. *For more details, please refer to the related links or feel free to contact us.
