 Features
of Equipment, Systems and Facilities
The water quality of reservoir and park pond is often degraded by water
bloom due to eutrophication and photosynthesis. The system is a floating
water-purifying device to suppress the proliferation of cyanobacteria
by stirring water with screw propellers which are driven by PV power
derived from sunshine, the prime cause for water pollution. The unit
revolves around an anchoring point to cause wide-spread convection,
thus disrupting anaerobic and thermal inversion layer in the bottom.
In its place, warm water and oxygen are fed into the bottom to activate
the natural purifying mechanism.
- Energy saving
Running cost of solar type is zero. Energy saving type requires only
AC 100 V power supply for home use.
- Efficient water stirring mechanism (screw propeller)
For stirring a large volume of water, the screw propeller system is
preferred to pumping type system.
- Auto-running mechanism (circular movement of unit)
The main unit revolves around an anchoring point driven by stirring
with screw propeller. In spite of its small size, the unit can stir
a large volume of water uniformly without leaving dead spots.
- Easy installation (floating system)
The floating unit can readily installed and displaced by a tug-boat,
requiring no divers' work.
- Lower cost, smaller size and simpler construction than conventional
devices
The cost is extensively reduced in comparison to the conventional
systems.
- Simple maintenance
Owing to simple construction, failure occurs rarely and easy maintenance
is ensured in contrast to the conventional systems. The floating construction
spares costly checking by divers and can be fully maintained on the
water.
