Flotation is also one of the processes used for the recovery of recycled paper and wastewater treatment. A high froth flotation efficiency is limited to the narrow particle size range, between 50 and 600 μm for coal as shown in Fig. 4.9 [81]. The coarser the coal, the harder it is to stay attached to the air bubble.
The lowest deinking efficiency of 12.9% was obtained using newspaper, with a 50% final brightness (5 unit increase compared with blank paper) ().This result was consistent with Ibarra et al.,who obtained 3–4 units of increased newspaper brightness after enzymatic deinking using cellulase and hemicellulase.In addition, Morkbak and
process designs and flotation cells. A study comparing the results of each plant’s deinking system performance identified differences in flotation cell operating conditions [1], the effects of which were not well understood. In many plants studied, the operating consistency of flotation cells had been elevated above design levels to increase
By comparing the experiments in the E18 cell and E250 cell in flotation deinking a mixture of ONP and OMG, scaleup of the frothing agent spray concept was successfully demonstrated using large scale of flotation cell (250 cell). Table 1. Comparisons of the performance of flotation deinking of a mixture of OMG and ONP using a
Mixed office waste paper (MOWP) is a low cost, high quality and easily collected fiber source for the papermaking industry. Unfortunately, limits in the application of traditional deinking are related to the negative environmental impacts of using chemicals during the deinking process. Hence, enzymatic deinking has received growing attention
Deinking of secondary fibers involves dislodging ink particles from fiber surfaces and separating dispersed ink from fiber suspensions by washing or flotation. Enzymatic approaches involve attacking either the ink or the fiber surfaces. Different enzymes have been used for deinking, including lipases, esterases, pectinases, hemicellulases,

DEINKING The floatation process for deinking pulp has won great acceptance in Europe due to its high yields and low water usage. The floatation principal was first developed for use in the mining industry for the separation of metallic elements from ore. Pierre Hines was the first to consider floatation for fiber deinking in the mid

2.1.3. The industrial flotation deinking process The flotation deinking in the mill begins with the pulping of paper and magazine in a drum pulper, with the addition of chemicals, the ink is released from the fibre. The mix is then screened to remove staples, plastics and other debris. The pulp is then set to react in a reactor or swelling tower
The application of enzymatic deinking improved ink removal efficiency by 24.6% and freeness by 21.6% with a reduction in drainage time of 11.5% in comparison to those obtained with chemical deinking. The physical properties, namely burst index and tensile index, were observed to improve by 15.3% and 2.7%, respectively and brightness and
