The process of flocculation is applicable to water purification, compaction and dewatering of sludge, in which the result is an aggregation of particles formed during the coagulation step and the formation of the so-called flocs. Such treatment can be applied only after coagulation since the reduction of repulsive forces between the particles favours their formation in aggregates, and flocculation, in turn, promotes growth and accelerates the separation of these phases from particles. The process takes place under the influence of a polymer - a substance composed of high molecular weight molecules formed from a large number of identical molecules called monomers linked by covalent bonds. The electric charge (+ or -) of the flocculant is chosen depending on the nature of the particles dissolved in the water, usually, an anionic flocculant (-) is applied to mineral particles and a cationic flocculant (+) to organic particles.
Flocculants (+ or -) are sold in solid and liquid form:
Dry, powder
Liquid, 0.15-0.35%

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.
