The effectiveness of using reservoir pressure maintenance systems directly depends on the presence of solid suspended particles in the process and formation fluid. The presence of a large amount of suspended particles leads to abrasive wear of surface and downhole equipment and clogging of the bottomhole formation zone. Therefore, standards have been developed that strictly limit the maximum content of mechanical impurities. Meeting of these requirements requires using massive systems in combination with the use of coagulants. To ensure the required high quality of water, a modular water treatment system (WTS) was developed and implemented. The small size and modularity of the WTS allows achieving the required performance conditions and facilitates installation and maintenance at various facilities of the reservoir pressure maintenance systems. The development of a methodology and a stand for carrying out full-scale tests allow simulating various operational conditions and determining the necessary periods of purification stages regeneration to increase the efficiency of work throughout the entire operational period.
