A static mixer tank includes upper/first and lower/second mixing chambers, with the two mixing chambers being separated by a swirl chamber. The upper mixing chamber is arranged at an upper end of the mixing tube where materials would initial begin passage there through, and the lower mixing chamber is arranged at a lower end of the mixing tube and receives materials that may have to some degree been mixed by their passage through the upper mixing chamber. A series of baffles in the mixing chamber are arranged in sinusoidal or saw-tooth pairs that can be oppositely arranged, so that the mixer turns a drop of water into hundreds of micro-bubbles of rotating fluid, which allows the chemicals to exit the mixer and react with fluid in a storage tank as much five times faster than previously known. A variation includes a sand trap using the swirl chamber, cap, diverter chamber, and diffusing plate to separate sediment from a liquid without using a filter of moving parts.
