Method and equipment for two-stages pressure discharge flotation in container - involves already cleaned water in two stages being sucked from second handling stage by dispersal pump with air or gas feed

摘要

In a subsequent saturation reactor (5), the air or gas is fed under pressure into the water flow, so that in a following water jet pump (6), with pressure discharged a water-gas dispersion is free, which with eddy formation, mixes with the chemicals and raw water fed into the controlled feed positions (8) which the water jet pump receives from the raw water pump (7). A total flow is thus formed and flows into the flocculation reactor (11) enclosed by a lower container (14). After the exit of flocculated water impurities such impurities are transported by air and gas bubbles into an upwardly open compression cone (12). This separates the lower container part from the upper container part (2). USE - For water purification purposes.
