Hygienic requirements and standards for drinking water quality

  1. Hygienic requirements and standards for drinking water quality
    The quality of drinking water is the basis of epidemiological safety and public health. High-quality water is an indicator of high sanitary well-being and living standards of the population, provided with centralized water supply. In developed countries, the state and health authorities pay special attention to the quality of drinking water. Drinking water must comply with SanPiN
  2. Scientific substantiation of hygienic norms (standards) of drinking water quality
    Water can fulfill a positive role in preserving and strengthening people's health, in the prevention of infectious and noncommunicable diseases, in creating proper sanitary conditions only if its quality meets certain requirements. Each type of water has certain hygiene requirements. There are scientifically based hygienic standards for water quality and rules
  3. Hygienic requirements for the quality of drinking water
    The standardization of the quality of drinking water is one of the important preventive measures of a state nature. In the process of development of standardization, the criteria for water safety for public health have changed as medical and biological knowledge has accumulated, as well as technical advances to improve water quality. Initial rationing of drinking water quality
  4. Hygienic requirements for the quality of drinking water
    Water quality requirements are determined by GOST “Drinking water. Hygienic requirements and quality control "(2874-82; see also" Guidelines for the implementation of the new GOST 2874-82 No. 3143-84), which applies to drinking water supplied by centralized drinking water supply systems and water pipelines, used simultaneously for drinking , economic, technical and
  5. Methods for improving the quality of drinking water. Disinfection of drinking water at centralized water supply and in the field
    There are many methods to improve water quality, and they allow you to free water from dangerous microorganisms, suspended particles, humic compounds, from excess salts, toxic and radioactive substances and odorous gases. The main goal of water treatment is to protect the consumer from pathogenic organisms and impurities that can be dangerous to human health or have unpleasant properties (color, smell, taste
  6. Hygienic requirements for water quality of surface water bodies and assessment of the conditions for discharge of wastewater into them
    Hygienic conditions for the water quality of surface water bodies depending on the types of water use in our country are regulated by SanPiN No. 4630-88. On March 1, 1991, Ukraine introduced the "Rules for the Protection of Surface Water from Wastewater Pollution" of the State Committee for Nature Protection of the former USSR. These rules set additional requirements for water quality
  7. Hygienic requirements for the installation and operation of water from surface water sources. Water Quality Improvement Methods
    Currently, 84% of the total amount of water supplied to cities and towns is taken from surface water bodies. Reliable and uninterrupted operation of the drinking water supply system largely depends on the choice of the location of the water intake. It is important to consider hydrological, sanitary and technical and economic conditions, among which the main, determining, factor is sanitary.
  8. Sanitary requirements for drinking water
    When assessing water for animals, they use the “Sanitary rules and norms for drinking water supply” (SanPin-10-124 RB-1999), approved by the chief sanitary doctor of the Republic of Belarus (10.19.99) and entered into force on 01.01.2000, as well as additions to them March 26, 2002. Drinking water should be safe in epidemiological and radiation terms, harmless in chemical composition and have
  9. Hygienic assessment of drinking water treatment methods
    Methods for improving the quality of water (water treatment) include: basic (clarification - removal of suspended solids from water, discoloration - removal of colored colloids or dissolved substances, disinfection - destruction of vegetative forms of pathogenic microorganisms) and special (desalination, defluorination, softening, fluoridation, deferred - zivanie, detoxification, deodorization, decontamination).
