摘要

本文介绍了反渗透膜和超滤膜磁力水处理装置在水和排水清洗联合装置中所涉及的工艺研究结果。强调了磁水处理方法在纠正纳滤过程中的潜力。为防止反渗透装置和超滤装置膜表面形成胶体和盐沉积,提出了使用磁性水处理装置的新方案。考虑流体动力流动和扩散过程,考虑了膜系统的数学模型,该模型能够评估膜装置中沉积物的形成强度。膜系统模型考虑了磁水处理对纳滤过程的影响。本文介绍了在实验室台架上用反渗透膜装置进行海水淡化的实验数据,该装置装有影响磁场净化水的附加组。

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.
