Development of a combined structure design to increase the efficiency of drinking water purification

Abstract Ensuring high-efficiency and cost-effective water treatment remains a significant challenge in modern environmental engineering. This study presents a novel combined water treatment structure that integrates thin-layer clarifiers, a vortex chamber, and an optimized filtration system within a single compact unit. The research aims to develop a combined design to increase the efficiency of purification and improve the methodology for its calculation, which makes it possible to adapt the facility to different flows and levels of water pollution. The proposed calculation makes it possible to simultaneously consider the interaction of all blocks (coagulation chamber, thin-layer sedimentation tank and filter), vary the filtration rate and settling velocity, integrate calculations of geometric parameters and hydraulic characteristics in a single algorithm. The compact and energy-efficient design reduces land use, operating costs and filtration load. In addition, this research lays the foundation for future technological advances in energy-efficient water treatment solutions, contributing to the modernization and sustainability of the global water treatment infrastructure.
