If the reservoir is not given proper attention, thenIn the meantime, its condition worsens - the banks are showered, unnecessary impurities accumulate in the water, which enter into it with sewage and thawed waters or with atmospheric precipitation; fungal spores and insect larvae reproduce in the silt sediments at the bottom of the reservoir. And if the river is exposed to the risk of pollution to a lesser extent, thanks to the current, ponds and lakes without timely cleaning in a short time become unfit for bathing, or for breeding fish, or for watering garden areas and gardens. In small decorative ponds or swimming pools, which are located in the suburban area, cleaning can be done on their own. To maintain large reservoirs there are special services equipped with appropriate equipment and how they monitor the cleanliness of water bodies depends not only on the state of a particular lake or gulf, but also on the ecology of the planet as a whole.

How is the treatment of reservoirs

Cleaning of water bodies of any size can occurin one of four ways. Each of them is effective and widely distributed on the territory of both Russia and the world as a whole. Small water reservoirs can be cleaned with the help of ultraviolet radiation. A sealed chamber with a UV filter is lowered into the reservoir, which generates radiation of certain frequencies, killing harmful viruses and pathogenic bacteria. Advantages of this method are that no chemical reagents enter the water and human intervention consists only in the timely replacement of components and maintenance of the device. The chemical method of purification consists in the operation of special reagents placed in water. They not only save unnecessary vegetation in the pond, but also saturate it with oxygen, regulate its acidity. Most chemical reagents do not harm either the person or his pets. For biological treatment, a container is used with bacteria that feed on organic substances while simultaneously removing water from vegetation and pollution. The most common method is mechanical cleaning of reservoirs, during which water is passed through filters of gravel, quartz sand or a mixture thereof. The mechanical filter consists of several stages with different density, on which remains unnecessary organic matter, mud, and other impurities. After carrying out the procedure, the installation can be washed with running water or replaced with filters, in case of their strong clogging.

Signs of pollution of the reservoir

Clear signs that the pond needscleaning, there are several factors that can not be noticed which is almost impossible. The first bell is a variety of pollution on the surface of the water, for example, leaves and branches of trees, pollen and stems of herbs and plants, fluff of waterfowl. In the next stage, the water begins to exude an unpleasant smell and is covered with a film similar to residual oil products in the form of oily multi-colored spots. The third, more complex form is active growth of algae, duckweed. Cleaning of such contaminants can be carried out only mechanically, in several stages. The fourth, the most complicated form of pollution is the release of gases with an unpleasant odor from the bottom of the reservoir. In this case, it is already impossible to cope without the help of specialists and ecologists. The contents of the reservoir must be removed, the silt layer should be removed from its bottom and disinfected with chemical reagents.
