The patented LSGM – liquid solid gas mixing heads manages the flocculation processes in a precise manner. Using air pressure (psi), a vortex, or hydro-cyclone, is created in each head, allowing bubbles to spin at various speeds and energies. As the wastewater moves through the system, strictly controlled pressure drops allow bubble formation in various sizes all the way to nano-bubbles. Small waste particles are more likely to attach to smaller bubbles.
In the LSGM heads towards the end of the process, long chain polymers are injected under pressure. They uncoil giving more area of charge sites for waste particles to attach.
Prior to the last LSGM head, the pressure is dropped to ambient pressure and the flocs, already formed around the waste particles, pop to the top of a bloom chamber.
By the time the wastewater enters the flotation tank, the solids and liquids are already separated. The tank is only used to skim the solids. This is why the tank can be so much smaller than a conventional DAF (dissolved air flotation) system.
