EnviroChemie has received German utility model protection for the Flomar® series’ specific dissolved-air flotation system.
This particular version is particularly well suited to depleting solids from highly polluted exhaust air treatment wash cycles, such as from washing towers or electrostatic precipitators.
The task is to reduce pollutants from the cycle without substantial use of salt to keep costs down. Complete clarification of the wastewater is not necessary.
Traditional dissolved-air flotation systems produce flotation motive water through air saturation of a partial flow in the plant outflow. The saturation usually takes place using multi-stage pumps, which only run smoothly if they are fed with pH-neutral wastewater mostly free from solids.
EnviroChemie’s injector system achieves micro-bubble formation comparable to saturation by pumps. The air saturation of the partial flow is carried out by an injector pressure container, which is fed by a wastewater pump resistant to solids, which can handle both alkaline and acidic wastewater without any problems.
This enables cycles to be driven through flotation systems without chemical conditioning or neutralisation. The flocculant dosage is required only to produce separable flocs. If floating solids are present without flocculation, a chemical-free procedure is possible.
