The "New Purification Device SG-1450" is a new purification system that does not require measures against E. coli because it does not accept toilet wastewater. Utilizing binchotan charcoal, it processes domestic wastewater from sources other than toilets, such as baths, laundry, and kitchens. The treated water has been confirmed by the Ministry of the Environment's demonstration project to be as clean as rainwater. Since there is no contamination from toilet wastewater, purification can be relatively easy, and no special qualifications are required for maintenance. It is proposed that wastewater from buildings be treated with a bio-toilet for toilet waste and the new purification device for domestic wastewater. 【Features】 ■ An upward flow waterway to prolong contact time with binchotan charcoal and ensure that oxygen necessary for biological treatment is distributed throughout the front of the waterway. ■ Purification is relatively easy since there is no contamination from toilet wastewater. ■ No special qualifications are required for maintenance because there is no contamination from toilet wastewater. ■ The treated water is clean like rainwater, making it reusable. ■ Purification utilizes binchotan charcoal. ■ Binchotan charcoal is inorganic, so it does not swell in water, and replacement of binchotan charcoal is unnecessary. *For more details, please download the PDF or feel free to contact us.

The "New Purification Device SG-870" is a new purification system that makes treated water as clean as rainwater. It utilizes binchotan charcoal to treat wastewater generated from baths, laundry, and kitchens, excluding toilet waste. Since toilet wastewater is not included, there is no need for measures against E. coli. We propose processing wastewater from buildings using a bio-toilet for toilet waste and the new purification device for general household wastewater. This product is designed for underground installation. 【Features】 - An upward flow water channel that prolongs contact time with binchotan charcoal and ensures that oxygen necessary for biological treatment is evenly distributed in the water channel. - Since toilet wastewater is not mixed in, purification is relatively easy. - No special qualifications are required for maintenance since toilet wastewater is not mixed in. - Treated water is as clean as rainwater, making it reusable. - Purification utilizes binchotan charcoal. - Binchotan charcoal is inorganic, so it does not swell in water, and replacement of the charcoal is unnecessary. *For more details, please download the PDF or feel free to contact us.

The "New Purification Device SG-640" is a new purification system that utilizes binchotan charcoal to treat household wastewater generated from baths, laundry, and kitchens, excluding toilet wastewater. Since toilet wastewater is not included, there is no need for measures against E. coli, and it has been confirmed through a demonstration project by the Ministry of the Environment that the treated water becomes as clean as rainwater. This product is recommended for use in general households. It is designed to be buried for use. 【Features】 ■ An upward flow type waterway that prolongs contact time with binchotan charcoal and allows oxygen necessary for biological treatment to circulate throughout the front of the waterway. ■ Since toilet wastewater is not mixed in, purification is relatively easy. ■ No special qualifications are required for maintenance since toilet wastewater is not mixed in. ■ The treated water is as clean as rainwater, making it reusable. ■ Purification is achieved using binchotan charcoal. ■ Binchotan charcoal is inorganic, so it does not swell in water, and replacement of the charcoal is unnecessary. *For more details, please download the PDF or feel free to contact us.
