12 wt%; temperature, 50℃; flotation time, 6 min; air to pulp r atio, 40%; pulp ﬂow velocity, 5.0 m/s; and ph value 11.0. under these conditions, the brightness of the ﬂotation deinking pulp reached 77.0% iso. zhang et al[ 1] optimized the omg deinking process with high pulp consistency and showed that a brightness of.
older flotation cells use a displacement float below the froth layer to measure the pulp height. pulp height is an important process measurement, used to ensure that liquid pulp is not allowed to overflow to the launders. if pulp overflows, the flotation cell ceases to function effectively, and this is very costly to the process. the.
A 10% increase in the paper recycling rate results in a reduction of 8.8 million tons of wastepaper in landfills each year. the mechanisms of pulp loss during froth flotation deinking are described in ajersch et al., mechanisms of pulp loss in flotation deinking, j. pulp and paper sci. 22, 9:j338-345.
Although, the deinking of paper pulp is usually conducted in a flotation cell with agitation, into which air is injected countercurrent to the feed. recent studies have focused on columns without.
And flotation cells the pulp suspension is pumped through the multi-injectors into the flotation cells. these newly de-veloped multi-injectors of the next generation mini-mize the pressure drop in the injector, hence reducing the energy demand. inside the patented injectors, the pressure energy is used to suck air into the feed.
Bubbles to the ink relative to the fibers and lowers flotation deinking efficiency and fiber yield. in the spray surfactant process this indiscriminant adsorption of surfactants on fiber and ink is reduced. rejects: foam + ink accepts: pulp suspension (deinked pulp) air pulp + surfactant figure 1: a simple flotation cell for recycled.
