The main body of water treatment equipment is typically made of stainless steel, corrosion-resistant carbon steel, or engineering plastics. Tanks, pipes, and support structures are fabricated through processes such as cutting, welding, and plate rolling. During this process, welding quality and anti-corrosion treatments (such as sandblasting, pickling, passivation, or epoxy coating) directly affect the equipment's pressure resistance and service life.
The core component manufacturing and assembly stage involves several steps. For example, in membrane systems, membrane module encapsulation and testing are required; in reverse osmosis systems, the membrane housing, pressure vessel, and high-pressure pump need to be assembled; and in chemical dosing systems, the metering pump and piping require precise assembly. This stage emphasizes sealing, precision matching, and material compatibility.
The system integration and electrical control installation stage involves connecting pumps, valves, sensors, and the PLC control system to achieve unified water circuits, electrical circuits, and control logic. This stage requires the development of automation programs to enable automatic operation, alarm protection, and data monitoring functions.
Before leaving the factory or after on-site installation, water pressure testing, flow rate verification, flux testing, and stable operation verification are required to ensure the equipment meets its design treatment capacity and effluent standards. For systems such as Membrane bioreactor, biochemical start-up and membrane flux stability tests are also required to ensure long-term operational reliability.
