Boiling and heavy water: This is another myth that was refuted 60 years ago, but continues to spread. Instead of a hydrogen atom, heavy water contains one (HDO) or two isotopes (D2O), which is called deuterium. Its content in water is approximately 0.033%, which is negligible. Firstly, heavy water is always found in natural sources, and sinceContinue reading “Boiling and heavy water”

Boiled water: Recently, more and more often the question has been raised about whether it is possible to drink boiled water. In order to understand this issue, you first need to understand what happens to water during boiling.Boiled water has similar taste to softened water  by a water softener plant. When heated to a temperature closeContinue reading “Characteristics of Boiled Water”

Scope of application: 1. Ultrafiltration, due to its advantages, has replaced the traditional water treatment schemes for centralized urban water supply, in particular in the process of groundwater post-treatment.It has similar features  to water softener plant. The image shows the Jeyran Batan drinking water plant, which supplies drinking water to the Azerbaijani cities of BakuContinue reading “Scope of Ultrafiltrataion”

– amphoteric – they contain different groups, are used in narrow areas. An important place in industrial water treatment is occupied by mixtures of cation exchangers . For example, DOW Amberlite resin . (On the image) In this case, cation exchange resin absorbs mainly metal ions, replacing them with hydrogen (H +), and anion exchange exchanges anions (sulfates, organic acids, hydrocarbons) with hydroxide ions. HydroxideContinue reading “Amphoteric Resins”

Ion exchange resins: Ion exchange resins are porous polymers that have a gel macro- or macroporous structure of different densities. On the surface of the pores are covalently bound ionic groups with exchanging ions fixed on the surface.It acts as an water filter for home Granules usually have the correct spherical shape when obtained by polymerization,Continue reading “Ion exchange resins”

Ion exchange technology: Ion exchange is one of the most effective water softening technologies. It is widely used both in domestic conditions and in industry. The ion exchange process is a reversible chemical reaction during which an exchange of ions occurs between the medium and the surface of the ion exchanger. It acts as an waterContinue reading “Ion exchange technology”

Modern sorbents for water purification :Nowadays, activated carbon is used for sorption water purification. Granular forms are usually used because they are more convenient to use. Depending on the quality of the feedstock and production technology, the specific surface area of ​​such coals reaches 800 – 1300 m² / g.  One of the largest manufacturers is the AmericanContinue reading “Modern sorbents for water purification”

Sorption Technologies: Sorption technologies are used in water treatment to clarify water and improve its organoleptic qualities by removing dissolved organic substances and gases.  In water treatment technology, activated carbons and others (often artificial sorbents) are used to reduce the color and odors of water. In particular, they are effective against natural humic acids, a wideContinue reading “Sorption Technologies”

Microorganisms present in water pose no less than other impurities hazard to human health. Therefore, effective disinfection of drinking water is a very important and integral stage of its purification. Today, it is the disinfection of drinking water that is the main problem for Pakistanand many African countries, where microbiological contamination of water is the main causeContinue reading “What is Disinfection of water?”

Today, various companies produce compact, easy-to-use ultrafiltration or industrial Ro plant cartridges, which are not inferior to UV lamps in terms of disinfection efficiency. Cartridges of this type are also recommended to be used after the storage tank for additional purification of water from possible microbiological contamination. What to do if you use jug or flowContinue reading “How-to-use ultrafiltration?”
