What is the LAKE-LYFTER？
|
| LAKE-LYFTER is a system developed for stagnant water areas for large-scale
convection of water. It generates the movement of the bottom layer of the
water to go up to improve the purification of water quality and help the
natural purification capacity. The LAKE-LYFTER system mixes the bottom
layer of the water and oxygen-rich surface water, aiming to purify the
water areas even when the temperature is high and the upper and lower convection
of the water is poor (during summer season where water temperature stratification
is easily formed). It helps the normal activities of the Eco-system, has
great effects to stop the abnormal growth of algae that will generate a
nasty smell on reservoirs and ponds . In addition , it will also help to
stir and mix chemical agents in the water thoroughly. |

Mechanism・Principle |
LAKE-LYFTER is a central system that is composed of self-standing float,
air lifting cylinder, air supply tube, induction inlet, chain, weights
and float . Each various part is made to be self-supporting in the water
and they float. The LAKE-LYFTER uses the reverse siphon action to make
air bombs. Air bombs that are accumulated in the air chamber within the
air compressor that is installed on the ground. The air bombs will blow
up in the inner chambers tube opening, as shown in the direction of the
arrows. This is when the air-lift phenomenon happens. The bottom water
that is absorbed from the induction inlet is pushed up. The bottom water
released on the opening upper end of the lifting cylinder will then be
mixed with the surrounding water while it goes up to the surface. Then
it will be mixed with oxygen-rich surface water, thus it incorporates oxygen.
By performing this series of operations intermittently, massive convectional
stirring is developed in whole water area, equalizes the water temperature
of both the lower and upper layers of the water. |

Features |
| 1. |
A simple structure, easy to install and manage. |
| 2. |
Significantly reduce the use of activated carbon and chemicals for water
treatment. |
| 3. |
Reliable and Energy-efficient design, full-time operation without an operator. |
| 4. |
Safe because it uses the natural water purification process and will not
affect the environment. |
|
Effects |
| ● |
Suppress the generation of algaes |
|
The biggest problem on the lakes is the abnormal occurrence of algaes
due to eutrophication. The occurrence of algaes can cause disorders such
as clogging on the filtration ponds and the musty odor, but with the circulation
effect of the LAKE-LYFTER, the abnormal growth of algae can be suppressed. |
| ● |
Water quality improvement of the bottom layer water |
|
The circulation action of the LAKE-LYFTER can remove the lack of oxygen
state of the bottom layers of the water. Therefore, iron and manganese
will begin to melt and suppress the release of ammonia and hydrogen sulfide. |
| ● |
Freezing Prevention |
|
In cold climates during winter, when the water freezes, the convection
action will prevent freezing and prevents damage to the water intake tower.

| ● |
Installing the LAKE-LYFTER in lakes is effective to prevent the lack of
oxygen in the bottom layer and suppress the growth of algaes, it has been
successfully installed in ponds, lakes and dams in Japan. It has achieved
good results especially on large-scale lakes for water supply source. |
| ● |
There is also POND CLEAN for smaller scale ponds with water depth of less
than 1. 5m. |
| ● |
Installing LAKE-LYFTER in seawater areas will improve water quality and
sediment, will prevent red tide and activate cultural farm. |
| ● |
As for blue-green algae countermeasures, it will be more effective when
combined with CarbonFiber(product name:MiraCarbon) |
| ● |
We can suggest the suitable installation with the various conditions of
the lakes, ponds, dams and etc, such as the shape, depth, water quality,
type, conditions and etc. |
