Modelling of RO installations for wastewater treatment plants

The investigation results of the processes involved in the combined plants for water and drainage cleaning, including an RO and UF membrane apparatus for magnetic water treatment, are presented in this paper. The potential of the magnetic water treatment method for correcting the nanofiltration processes is highlighted. New schemes are proposed for using the magnetic water treatment apparatus for the purpose of preventing the formation of colloid and salt deposits on the membrane surface of the RO and UF apparatuses. The membrane system mathematical model that enables the evaluation of the intensity of formation of deposits in the membrane apparatus were considered by accounting for the hydrodynamic flow and diffusion processes. The membrane system model accounts for the influence of the magnetic water treatment on the nanofiltration processes. The data of the experiments performed at the laboratory stand with water desalination via a RO membrane apparatus equipped with the additional group for influencing the water cleaned by the magnetic field are introduced in the current paper.
