Temporary water treatment refers to water treatment in situations where permanent facilities cannot respond, such as during equipment renewal construction, unexpected troubles, or limited-time operations. In temporary water treatment projects, it is essential to assemble treatment solutions and respond flexibly based on the specific conditions of each site. Since its establishment in 1974, Seisui Kogyo has specialized in water treatment and sludge treatment, accumulating on-site experience and responding to the needs for temporary water treatment. The company has a proven track record in various applications, including industrial wastewater, sewage, emergency responses during disasters, and civil engineering sites, and has not only provided equipment but also proposed optimal treatment configurations after organizing site conditions. Thus, temporary water treatment is one of the practical options to ensure that water treatment does not stop even within limited timeframes and constraints. For more detailed explanations about the concept and scope of temporary water treatment, please check the related links.

This catalog provides information on the temporary wastewater treatment system "Habuki," which is effective during renovation work, maintenance, and disaster recovery at wastewater treatment plants. By utilizing Toshiba's special rotating body for biological membrane treatment, it reduces BOD by 70% and total nitrogen by over 25% in a short time. It introduces a groundbreaking solution that significantly reduces the load on subsequent temporary aeration tanks and MBRs, achieving a space-saving (approximately 50% reduction) and energy-saving (about 33% reduction in electricity) for the entire plant. In particular, it explains the mechanism that enables overwhelming cost reduction and stable operation compared to disposal by vacuum trucks, using comparison tables. It also details an emergency recovery case from the flooding incident at the Genkai Town wastewater treatment plant that occurred in January 2025, where biological treatment was restarted in just three weeks, resuming processing at a municipal scale (1,000 m³/day). The total support system provided by Seisui Industry, which includes planning, installation, and operational guidance, is also mentioned.

We are introducing a case of residual sludge treatment during renovation work conducted by Seisui Kogyo Co., Ltd. During the renovation of the aeration tank, we faced a situation where we had to dispose of 8,000m3 of sludge inside the tank. Since vacuum treatment would incur high processing costs, we used a temporary dewatering plant to reduce the volume. As a result of the treatment, we were able to reduce the sludge disposal costs by approximately 73%.

Centrifuges, as dewatering treatment devices, possess many excellent characteristics and have been gaining attention in numerous fields in recent years. Over 80% of what is referred to as sludge is composed of moisture, and by reducing this to less than half, treatment costs can be significantly lowered. There is also technology that allows for the discharge of treated water into rivers in a non-toxic manner, making it environmentally friendly in light of serious global environmental destruction and pollution. In the past, it has even been featured in the Circular Economy Newspaper. There have been hundreds of successful cases, including treatment during hot spring drilling, sludge treatment at breweries, dairy factories, sewage treatment facilities, sludge treatment at beverage factories, manure treatment at pig and cattle farms, oil drilling promotion, water treatment at purification plants, dredging projects for dam construction, river dredging, sludge treatment for contaminated soil, and oil sludge treatment at refineries, among many other applications. There are also numerous achievements in civil engineering, including its use in foundation work for highways and tunnel excavation projects.
