Pond water quality improvement of the sea

Elimination of water bloom

In the still water area like dam, exceptional reproduce of algae especially microcystis leads to serious environmental problems.
Microorganism kwon as cyanobacteria is extremely easy to reproduce in eutrophic water area. In high temperature condition, it will exceptionally reproduce and emit fetor and toxicity.
Under photosynthesis, PH value increases in the day time, effecting downstream of the resource of tap water and causing problems with the quality of water.

PCα21Ca can be utilized to eliminate the water bloom problem to increase the quality of the water.

Effects of Agglutination process
  1. Improve the quality of water

    Agglutination agent is quit flexible and is able to deal with the change of change of season and temperature.

  2. Quick effect, improve the transparency

    Agglutination agent is able to eliminate suspending substance to quickly improve the quality of water
     

  3. Improvement of the quality of bottom water

    When the target pool becomes transparent, sunlight could shine into the bottomof the water directly, hastening photosynthesis effect and improving the quality of water.

  4. Elimination of fetor

    After the elimination of water bloom and the substance which causes the fetor, the smelly fetor will vanish away.
     

  5. Elegant and exquisite equipment

    Elegant and exquisite equipment could be used even in a narrow space.

    ※Based on water quality and pond, the shapes of river or head stream, the construction method will be different.

Purification system of pond and swamp and water quality management and control system(activated sludge method)
  1. Construction during the previous month, increasing the inherent self-purification capacity of natural lakes and ponds
    • Increase the amount of dissolved oxygen in ponds and micro-bubble aeration, aerobic microorganisms are activated to decompose pollutants in water.
    • The introduction of active oxygen complex, revitalize the aerobic microorganisms.
  2. Remove the cause of the contamination of the pond using our coagulants (such as organic Petro)
    • Emerged from the separation of suspended solids in • PGα21Ca
    • Separation of suspended solids due to the rise of Micro Bubble
    • Removal of suspended solids
  3. By activating the microorganisms and substances that cause differential inhibition of water pollution.

Strategy to deal with red tide

Nowadays, red tide which polluted the sea has been a serious problem all over the world.
Every year in Japan, tide causes big damage to fish and oyster aquiculture.
Up to now, what puzzles and bothers aquiculture is that there is no effective way to deal with red tide. But PG alpha Ca could effectively eliminate red tide which has been widely accepted.
The method of agglutinating and eliminating red tide is as follow. Please ask and consult for details to the staff who is in charge.
