Municipal Water Treatment, Industrial Water Treatment

 

Grit removal facilities should be installed to remove suspended matter that affects water purifying treatment such as contaminants and wood chips that have been carried in from rivers or lakes. We offer a wide range of pre-treatment facilities including rake-type and rotary-type facilities to meet customers' requests.

Clear water is obtained by sedimentation separation in which suspended matter is caused to coagulate in larger flocks. We offer our unique products including rapid and super-rapid sedimentation basins with features such as parallel inclined panels and scrapers.

We offer activated carbon treatment facilities with excellent energy and cost saving benefits that demonstrate high performance in removing malodorous substances such as fungus odors and precursor substances such as trihalomethane.  We have activated carbon regeneration facilities in our Sodegaura plant, where spent activated carbon is regenerated.

As one of the most experienced companies in the industry, we offer a variety of sand filtration facilities as a typical type of rapid filtration basin. Centering on the environmental-friendly Rapid Filtration System that consumes the minimum amount of energy, our product portfolio includes sand filtration facilities for cryptosporidium under the guidance of MHLW.

We are proud of our experience in installing comprehensive membrane materials including MF (non-organic, organic), UF, NF and RO. We offer the optimum membrane filtration facility that matches the request of each customer.  We recommend a submerged membrane for modification from an existing sand filtration facility to a membrane filtration facility because of its excellent energy-saving benefits and the fact that the existing structure can be reused.

Striving to improve the safety and operational convenience of disinfection facilities, we offer highly safe and sturdy disinfection facilities in various profiles from large volume types to small and medium volume types.

We offer various types of coagulant, pH adjustment agents, slaked lime feeding facilities and their control systems. Because we produce chemicals by ourselves, we can offer the optimum combination of chemicals and feeding facilities.

Wastewater thickening facilities are important for reducing the volume of sludge and improving the efficiency of dehydration treatment facilities at later phases. By effectively combining our unique treatment facilities, such as a gravity thickening basin, sludge scraper, mobile trough and filtration thickener, we offer wastewater thickening facilities that match the requests of each customer at optimum prices.

Various types of dehydration methods are available depending on the properties and control conditions of the sludge. We offer sludge dehydration facilities that match the requests of each customer at optimum prices.

Dehydrated cakes can be used effectively in agriculture, gardening and as a component of cement by adjusting the grain size and moisture content. To promote the recycling and reuse of resources, we offer sludge utilization facilities including crashing, drying and pelletizing processes.

Versatile solutions are available to meet customers' requests even when they require special treatment facilities such as countermeasures against degradation of lake and dam water, removal of volatile substances from groundwater and seawater desalination plants for remote islands.

We offer comprehensive types of monitoring and control systems dedicated for water treatment plants. Our central monitoring and control system LS16A series have been marketed widely since we launched the prototype in 1985. Currently, more than 130 facilities are using this system.
