Слайд 3
The problem of water pollution is especially acute in densely populated countries. In some regions of the planet, not only drinking water is lacking, in the dirtiest rivers it is unsuitable even for domestic needs.
Слайд 4
Water purification is one of the ways to solve the problem of water pollution. Business owners should attend to the installation of quality treatment facilities. The presence of such devices, of course, is not able to completely stop the release of toxic substances, but they are quite capable of significantly reducing their concentration.
Слайд 5
The use of recycling water supply technologies many times reduces the amount of harmful emissions, reduces actual water consumption, and reduces the loss of raw materials in production. In the process of purification, valuable substances that have got into the water during the production process are extracted from the contaminated liquid.
Слайд 6
Water quality refers to the chemical, physical, and biological characteristics of water based on the standards of its usage.It is most frequently used by reference to a set of standards against which compliance, generally achieved through treatment of the water, can be assessed.
Слайд 7
The most common standards used to monitor and assess water quality convey the health of ecosystems, safety of human contact, extent of water pollution and condition of drinking water. Water quality has a significant impact on water supply and oftentimes determines supply options.
Слайд 8
A rosette sampler is used for collecting water samples in deep water, such as the Great Lakes or oceans, for water quality testing.
Слайд 9
The river has two tributaries over 20 km long and a dozen smaller ones. Food - snow, precipitation and groundwater. The width of the ravine is 60-110 m, on the plain 300-450 m.
