Treatment of Ponds & Fountains |
|
| |
Many fresh water lakes and ponds are characterized, particularly during the warmer months, by a significant population of suspended algae or phytoplankton in the water bodies. This gives the water a greenish appearance. High concentration of algae may lead to depletion of the dissolved oxygen of water causing anaerobic conditions in the water bodies. This may result in death of aquatic population, besides an unpleasant odor. Envirocrobe is manly used for the control of algae in ponds/lagoons. In most cases, poor pond water is due to excess of organic matter, nitrogen, ammonia and phosphorus. These nutrients serve as a food supply for algae and other undesirable weeds. The microbes of EnviroWay products remove these organics from the water, thereby removing the available nutrient. This results in the elimination of algae/weeds. |

Treatment of Lakes |
-
| |
Enviroway introduces high potency, bacterial- laden, powdered formulation, for use in controlling algae, ammonia & nitrites though the reduction of organic matter and available nutrients in the water treatment of lakes. It further enhances water clarity by providing good settle-ability therefore restoring the aesthetic quality of various water bodies. It also provides a biological control. |
