The "Water Barrier" is a fence that has zeolite sheets sewn into the curtain. By installing the Water Barrier in rivers, lakes, ponds, and waterways, a maximum adsorption capacity of 203.7 mg/g for radioactive Cs contained in the water is expected. It is a sheet that carries powdered natural zeolite on pulp, with a carrying capacity of 500 g/m², and it removes Cs and Sr. Cs can be removed by over 80%, and Sr by over 20%. It is easy to install and requires no maintenance. It effectively adsorbs and removes nutrients such as nitrogen and phosphorus in the water, making it effective for preventing eutrophication. 【Features】 - Can be installed in rivers, lakes, ponds, and waterways - A maximum adsorption capacity of 203.7 mg/g for radioactive Cs is expected - With a carrying capacity of 500 g/m², Cs can be removed by over 80% and Sr by over 20% - Easy to install and requires no maintenance - Effective for preventing eutrophication *For more details, please refer to the PDF document or feel free to contact us.

This is a type of pollution diffusion prevention fence that uses anchors such as H-beams to keep a curtain upright underwater. It prevents the diffusion of pollution that occurs near the seabed and stops turbidity from crawling along the seabed, protecting shellfish, algae, corals, and other marine life. In cases where the water depth is deep, resulting in a longer hanging curtain and potential issues with buoyancy maintenance, a self-supporting type is recommended in combination with the hanging type. 【Features】 ■ Effective in deep water where buoyancy maintenance is problematic ■ A type that uses anchors such as H-beams to keep the curtain upright underwater ■ Short-term rentals are also available *For more details, please refer to the PDF document or feel free to contact us.

A popular type of pollution diffusion prevention fence that hangs curtains from the water surface. It prevents the spread of pollution generated during land reclamation, dredging, revetment, and river construction, protecting nearby marine resources. By allowing suspended SS (silt) to remain within the curtain, the sedimentation time for particles can be extended, and aggregation can also be expected. ★Rental options are available★ 【Features】 ■ A popular type that hangs curtains from the water surface ■ Short-term rentals are also possible *For more details, please refer to the PDF document or feel free to contact us.

During the water intake from dams, water supply systems, factories, etc., floating sheets or containers that do not rot drift down from upstream, causing clogging phenomena and becoming an obstruction. By extending a dust fence in front of the intake, we can prevent the intrusion of garbage and driftwood, thereby improving the water intake efficiency. If you provide us with the local site plan, cross-section, climate conditions, and water levels, we can also accommodate design requests. 【Features】 ■ Contributes to improved water intake efficiency ■ Extended in front of the dam to protect the dam body from the impact of driftwood. ■ By installing an aqua fence (partition fence) upstream of the dam for water quality improvement, we suppress the occurrence of plankton and prevent sediment inflow into the dam lake. ■ Installed at the water intake from the river to prevent the intrusion of garbage and driftwood. *For more details, please refer to the PDF materials or feel free to contact us.
