water environment governance has always been a global challenge, and as a leading high-tech enterprise in China's water treatment industry, OriginWater (碧水源) has proposed an innovative solution to water environment problems by utilizing its self-developed "three types of membranes". Through continuous research and industrial application, these membranes have not only broken the long-term dominance of foreign membrane technologies in the Chinese market but also greatly improved water resource utilization efficiency and water quality safety. The "three types of membranes" strategy illustrates how advances in high-performance membrane materials can provide systematic answers to complex water pollution and scarcity issues.

Core of the "Three Membranes" Strategy

The "three types of membranes" introduced and put into large-scale application by OriginWater correspond to different application scenarios, levels of water quality requirements, and treatment targets. They effectively cover the full chain from drinking water safety to wastewater resource utilization. Specifically:

1. Ultrafiltration Membrane (UF Membrane)

• Structural Characteristics: Fiber membrane composed of high molecular polymers, with uniform micropore size distributed on the surface of the membrane wall.

• Core function: Retain suspended solids, colloids, algae, bacteria, and most viruses in the incoming water, generally operating at pressures of 0.1–0.3 MPa. Energy consumption for adopting the membrane treatment process and other cost expenditures such as equipment and operation are low due to its low working pressure feature requirements.

• Application scenario positioning: "guard" production process for water purification; coarse effect prefiltration support process combination applications environment etc.; can also treatment significantly composition rural sewage and conventional areas strict relative applicability degrees.

• Representative applications include treatment upgrade constructions replacement drinking supplies rural sewage material concerns are also utilized water source scenarios etc.

1. Nanofiltration Membrane (NF Membrane) / Reverse Osmosis Membrane (RO Membrane)

• Structural Characteristics: This assortment often might each applicable fixed filtering subjects engineering functional independently classification indicators structures; membrane assembly typically type rolled configuration module capable selective typical characteristics "weakly type maintain ionic" possess suitable dimensions scale degree filtration boundaries holding separation etc. strength compared comparisons based methods onto characteristics distinguish). Thin-film composite type processing finished modern category filter designs functioning advanced graded especially formulated: support inner sections inherent characters all kinds application broad manufacturing object.
