The stainless steel reverse osmosis (RO) device is a high-efficiency water purification system that integrates the corrosion resistance of stainless steel materials with the precise separation performance of reverse osmosis technology. Its core working principle relies on the selective permeability of RO membranes and the driving force of pressure to realize the separation of impurities and pure water.

The pretreatment system, consisting of raw water tank, multi-media filter and precision filter, serves as the crucial first line of defense in the water treatment process for industries such as pharmaceuticals, food and beverages. Its core function is to remove various impurities from raw water efficiently, ensuring that the subsequent water treatment units (such as reverse osmosis or ion exchange) operate stably, and more importantly, meeting the strict water quality standards required for product production in these industries. The working principle of the system is a sequential and synergistic process, with each component undertaking specific tasks to form a continuous and efficient purification chain.

The EDI (Electrodeionization) ultrafiltration system is an integrated water treatment system that combines ultrafiltration pretreatment technology and EDI deep desalination technology. Its core function is to efficiently remove suspended solids, colloids, organic matter, and ionic impurities from raw water through the synergy of "pretreatment-deep purification", and finally produce high-purity water. It is widely used in electronics, pharmaceuticals, food and beverage, electric power and other fields with strict water quality requirements. The working principle of the system can be carried out around three key links: "pretreatment stage", "EDI core reaction stage", and "product water and concentrated water discharge stage", which are closely connected and functionally complementary.

Nanofiltration is a relatively recent membrane filtration process used most often with low total dissolved solids water such as surface water and fresh groundwater,with the purpose of softening and remove of disinfection by-product precursors such as natural organic matter and synthetic organic matter.The main fuction is to separate and purify different components in liquids.The system uses the selectivity of the membrane pore size and uses the pressure difference as a driving force to allow solvents,inorganic ions,small molecules and other substances to pass through the membrane,while retaining particles and macromolecules,thereby achieving the purpose of separation and purification.
