Water quality improvement of the dam: Low maintenance costs (electricity costs), propeller-type water circulation device.
Propeller-type lake water purification device "Aqua Fine"
By utilizing a "propeller" that can efficiently move water, minimize electricity costs! "Propeller-type lake water purification system"
【New Information】 The General Incorporated Foundation Water Source Environment Center (WEC) has compiled the installation and operation manual for the propeller-type lake water purification system. 【Achievements】 More than 30 units are currently in operation at dams and reservoirs nationwide. 【Functions of Aqua Fine】 1. Suppression of algal blooms 2. Resolution of hypoxia 3. Measures against manganese "Aqua Fine" sends algal blooms that proliferate in the surface layer down to deeper water, inhibiting their growth by blocking photosynthesis. Additionally, it transports oxygen-rich surface water, which is abundant in oxygen, to the bottom layer where oxygen is most needed, thus resolving the hypoxia issue. By improving the hypoxic conditions at the bottom layer, it can also suppress the leaching of manganese from the bottom, making it effective as a measure against manganese. 【Features】 - Capable of suctioning a wide area of surface water. - Can efficiently circulate large volumes of water with low power consumption. - Low maintenance costs (electricity costs). - The drive unit is above the water surface, making maintenance easy (diver not required). - Completely custom-made according to the site's hydraulic environment. Support is available from design, manufacturing, and construction to maintenance, providing a seamless service.

basic information
Regarding the scale of the equipment, it will be individually designed according to the usage environment. We also provide design cooperation for consulting services related to design and construction, so please feel free to contact us. Our company was founded by engineers from a shipyard who became independent. We applied the propeller technology cultivated in shipbuilding to improve water quality in dams. More than 30 units are currently operational in dams and reservoirs across the country. From the stage of water quality measurement to design, manufacturing, construction, and subsequent maintenance, we contribute to the improvement of water quality in dams with our comprehensive in-house support system. 【Main Specifications】 ■ Flow rate: 1000–4000 m^3/hour ■ Power supply (land power): AC 200V 3-phase ■ Equipment structure: Stainless steel (SUS304) ■ Water delivery pipe: Polyethylene pipe ■ Operation and control panel: Outdoor freestanding type ■ Others: Monitoring via remote surveillance (the status of the equipment can be checked on a computer or smartphone)
Price information
