Water Purification Example by LAKE-LYFTER |
Example.1 Uragami Reservoir
■Installation Place
・Name
・Volume of Water
・Warter depth
|
:Uragami reservoir(For tap water)
:1,790,000㎥
:13m
|
■Specification
・Model
・Number of Machines
・Compressor
|
:LSN-50-0500
:1 Unit
:7.5kw×1 |
■Outline
Compared water quality data of two years before LAKE-LYFTER installation
with five years before, and one year after installation.In vertical distribution
of water temperature, although it was a low temperature in bottom area,
improved by circulation and became uniform temperature. Regarding the water
quality index, as oxygen was supplied to the bottom layer area, dissolved
oxygen(DO)increases,the algae such as chlorophyll-a etc was restrained
by ammonium nitrogen decrease. pH is going down as photosynthesis by algae
decrease. Development of odor declines in both of bottom layer and surface
layer by these synergistic effect,water quality isimproved in water area.

Example.2 Sakuna Dam
■Installation Place
・Name
・Volume of Water
・Water Depth
|
:Sakuna dam(For tap water reservoir)
:630,000㎥
:20m
|
■Specification
・Model
・Number of Machines
・Compressor
|
:LSN-30-0800
:2 Units
:3.7kw×1 |
■Outline
Compared water quality data in water depth of three years before LAKE-LYFTER
installation with it after installation.In vertical distribution of water
temperature, although it was a low temperature in bottom area,improved
by circulation and became uniform temperature. As for water quality, dissolved
oxygen (DO) increases since oxygen was supplied to thebottom layer area,
chlorophyll-a decreases by ammonium nitrogen decrease,water quality is
improved.
