Trials to Purify Polluted River

Polluted but still alive

As we have tested T.S Minetase's vitalization effect on various animals and/or plants, we have gradually become confident that the vitalization effect can be extended to an ecological recovery of polluted rivers or ponds.

T.S Minetase, by stimulating remaining lives in the polluted water, vitalizes ecology system of the nature. It is to vitalize self-recovery capability of the nature. From the summer of 2002 through December 2003 we conducted 6 test cases, 4 small rivers and 2 ponds.

Summing up 6 cases, we observed

  • Effectiveness in quick elimination of foul odor of polluted water.
  • Remarkable effectiveness in decomposing and dissolving sludges.
  • Signs of recovering ecosystem such as fishes coming up, algal growth, etc. This recovery sign was stronger in rivers of which the bottom or the side was covered by soil and mud (not cemented).
  • Increased transparency of water. Clear but not colorless.

All of them seemed to promise recovery of polluted environment. 2 out of 6 trials are picked up and explained in detail, Trial at Shinkawa, Trial in Okinawa.

Activation mechanism of "T.S Minetase"

There is no ecosystem environment where only one living organism exists. Even in a water pool where one big fish of 2 meters is being fed, microscopic organisms resident in filtering layers play an important role to vitalize the fish.

Generally speaking, boundary zone of water is a colony of microscopic organisms. But the microscopic organisms can adapt to organic boundary much easier than inorganic one. In case of water pool, the boundary zone is inorganic substance such as glass and metallic substance.
Air is another boundary zone, but is artificially controlled. Then, it is quite difficult to vitalize microscopic organisms in such inorganic or artificial boundary zone.

Different from inorganic boundary zone of water pool, natural rivers share boundary with soil, mud and natural air. Rain sometimes falls and wind blows. It provides much better condition for nourishing microscopic organisms. I have accumulated experiences and know-hows of managing inorganic boundaries for feeding fishes. Then, compared to water pools, natural rivers, even polluted, have more opportunities of vitalization.

At an early stage of injection, "T.S Minetase" stimulates and vitalizes microscopic organisms resident in the boundaries such as soil, mud and air. It prompts vitalization of all other ecosystem. This is considered to be a mechanism of "T.S Minetase" to activate polluted rivers or ponds.

Density consideration

Density of "T.S Minetase" is an important factor. Minimum density which can trigger activation depends on remaining nature. If the polluted river has nature-rich boundary zones, even 1 ppm of "T.S Minetase" can trigger activation.

Take an example of pouring 10 litters of "T.S Minetase" into a river, 5 meters width and 2 meters depth. Water volume of 1 km length is equivalent to 1 ppm. If 2 ppm is required, 20 litters must be poured. This calculation indicates purification of polluted river by use of "T.S Minetase" is a practical solution. But, it is also important to continuously use "T.S Minetase". It must be poured into the polluted river periodically. No need of one time heavy investment, but continuous spending is required.
