1. Product Introduction | Manufacturer of ultrafiltration and reverse osmosis equipment

Lifeierte is an integrated manufacturer covering research & development, machining, assembly and after-sales service for ultrafiltration and reverse osmosis equipment. The ultrafiltration unit adopts modified hydrophilic PVDF hollow fiber membrane as the core pretreatment component, while reverse osmosis equipment uses polyamide composite RO membrane for deep desalination. The whole combined system consists of raw water pretreatment tank, multimedia filter, cartridge security filter, ultrafiltration membrane module, UF automatic cleaning system, intermediate buffer tank, RO high-pressure pump, dosing system for scale inhibition and disinfection, membrane pressure vessel, concentrated water discharge pipeline and PLC centralized control cabinet. All products are processed and assembled in our own factory workshop, with every production link under internal supervision, avoiding middlemen markup and unstable product quality from third-party outsourcing processing.

According to different project environments and water production demands, we supply serialized RO hosts matched with self-made ultrafiltration equipment. For remote mining sites, temporary construction water and mobile water supply projects, sealed plug-and-play Standard Containerized RO Unit is perfectly matched with supporting ultrafiltration assemblies to realize fast deployment without complicated civil construction. For chemical plants, metallurgy factories with outdoor installation conditions, anti-rust and temperature-adaptive Outdoor Industrial Reverse Osmosis Equipment works stably together with ultrafiltration devices under harsh open-air environments. For industrial park centralized water stations and large-scale pure water workshops, high-volume array-type Large-scale RO Equipment supports parallel operation with large-size ultrafiltration equipment to meet tons-level continuous water supply needs. For most conventional factory pure water preparation projects, the mature general-purpose Industrial RO System forms the most cost-effective standard UF-RO technological process with conventional ultrafiltration equipment. For small factories and laboratories with limited installation space, miniaturized Integrated Reverse Osmosis Unit is matched with compact ultrafiltration modules to save workshop floor space effectively.

Standard frame and pipelines of all equipment adopt SUS304 stainless steel material; SUS316L stainless steel and carbon steel anti-corrosion coating are available for customization against corrosive raw water. Our self-programmed PLC control system realizes synchronous automatic backwashing of ultrafiltration and automatic flushing of reverse osmosis membranes, supporting remote data viewing, pressure abnormal alarm and automatic protection shutdown functions. As the original manufacturer, we provide customers with process calculation, layout drawing design, on-site installation guidance, long-term spare parts supply and lifelong free technical training services.

2. Working Principle of Ultrafiltration & Reverse Osmosis Combined Equipment

The whole water purification process is divided into ultrafiltration pretreatment section and reverse osmosis deep desalination section, two membrane processes cooperate to complete graded purification of raw water under pressure driving.

2.1 Working Principle of Ultrafiltration Equipment

Ultrafiltration adopts cross-flow filtration mode with 0.01~0.1μm membrane aperture. Under low pressure drive, water molecules penetrate hollow fiber membrane walls to produce permeate water, whereas suspended solids, colloids, bacteria, algae and macromolecular organic matter are intercepted on the membrane surface. Timed automatic backwashing and periodic chemical cleaning remove membrane surface pollutants, stabilize ultrafiltration water yield, reduce RO inlet water SDI value below 5 and form effective physical protection for expensive reverse osmosis membranes.

2.2 Working Principle of Reverse Osmosis Equipment

Ultrafiltration qualified produced water enters the intermediate tank, boosted by high-pressure pump to reach the rated operating pressure of RO membranes. RO membrane has nanometer microporous structure; pure water passes through the membrane layer under high pressure, while inorganic salts, heavy metal ions and residual small-molecule organics are trapped in concentrated water side to realize deep desalination and purification of water quality. The built-in automatic flushing program slows down membrane surface scaling and pollution, prolonging the service cycle of RO elements.

2.3 Coordination Mechanism Between Two Devices

Ultrafiltration removes most particulate pollutants to improve inlet water quality for reverse osmosis; reverse osmosis achieves the final standard-reaching of pure water. The two sets of equipment are linked by the central control system to realize unattended continuous automatic water production operation.
