Scope

Scope: This document specifies the terms and definitions, basic requirements, purification effect testing, equipment installation, commissioning, operation, maintenance, and water quality hygiene and management requirements for integrated water purification equipment. This document applies to the production, testing, and operation management of integrated water purification equipment for domestic drinking water using surface water or groundwater as raw water; Main technical content: This document defines integrated water purification equipment as an integrated modular water quality treatment device. The integrated water purification unit includes a combination of multiple functional modules such as coagulation, sedimentation, and filtration, and is equipped with modules such as drug addition and disinfection devices for treating surface water or groundwater. The treated water quality meets the hygiene standards for domestic drinking water. It is divided into conventional process integrated water purification equipment and membrane process integrated water purification equipment. Conventional process integrated water purification equipment consists of modules such as drug addition, mixing, flocculation, sedimentation (or clarification, air flotation), sand filtration, disinfection, and backwashing. Membrane process integrated water purification equipment consists of modules such as pretreatment, membrane filtration, disinfection, physical cleaning, chemical cleaning, inlet and outlet drainage, and control. Membrane filtration includes microfiltration, ultrafiltration, nano-filtration, and reverse osmosis water purification equipment. Ultrafiltration membrane filtration includes pressure-type ultrafiltration membrane integrated water purification equipment and immersion-type ultrafiltration membrane integrated water purification equipment. This document specifies technical requirements for the hygiene requirements of integrated water purification equipment, material a
