Textile and leather industry: The variety of process waters from these industries is significant depending on the specific activity, but in general they need to reduce the high levels of biological oxygen demand (BOD5) and organic load due to the processes of bleaching, washing and dyeing. of textiles, as well as tanning of leather (blood, sand, manure, fibres, etc.). The offered equipment is successfully used in factories for dyeing of textiles and wool, leather factories, etc. and has been successfully instaled on field site in the municipality of Sliven

Anaconda® flotators are highly efficient (up to 99%) systems for physico-chemical removal of undissolved substances from wastewater. The purification of pollutants here takes place through a combination of several processes: coagulation, by adding the appropriate chemicals are formed the so-called "flocs" (aggregated parts of pollution), flotation in which, under the influence of dissolved air the already formed flocs "float" which leads to their removal from the surface scraper and precipitation of larger and heavier particles, which are subsequently removed from the bottom assisted by a lamellar system. The operation of the offered equipment is fully automated and easy to control through a PLC control module equipped with a touch screen, in addition to which it is equipped with emergency shutdown and security systems, pneumatic control circuit and air injection.

In the process of water purification, the finest particles dissolved in the water do not settle while the water is at rest, as they are negatively electrically charged and repel each other. In order to achieve a better effect of their removal, chemical treatment is used. In this method, positively charged substances are introduced into the water, which enter into a chemical reaction with those dissolved in water and form aggregated neutrally charged compounds. The agglomerations thus obtained in the form of large flocs are rapidly deposited, and in the presence of stirring of the liquid the effect is higher. This process is called coagulation-flocculation, and the substances used are called coagulants. The choice of the optimal coagulant for a particular water to be treated is determined on the basis of laboratory tests.
