Sažetak
The investigations presented in this work refer to the possibility of waste water refining from deinking flotation process by the method of membrane separation. The offset printing impressions made with the conventional printing inks as well as the models based on the raw materials of renewable origin were used in the recycling process. Before and after the water treatment, the concentration of the sulphate, chloride, nitrate, total organic substance, oxygen consumption, pH and electric conductivity was determined in all the samples by standard analytical methods. The investigation results point at the dependence of the concentration of the investigated inorganic and organic pollution with the characteristics of the prints used in the recycling process. The concentration decrease of the investigated pollution using the method of the membrane separation in relation to the boundary values of the water quality necessary for the paper production has been discussed in the paper. Apart from the specific scientific contribution, the practical application of the investigation is the contribution to the closing of the water circuit in paper production.
