1. Product Introduction of Ultrafiltration System Equipment

As a professional ultrafiltration system equipment manufacturer, we take organic PVDF hollow fiber membrane and inorganic ceramic membrane as the core filtering medium, and integrate membrane module assembly frame, raw water supply pump, backwashing pump, chemical dosing cleaning unit, security filter and PLC intelligent control cabinet into an integrated whole set of ultrafiltration system. All finished products pass factory hydraulic pressure test and 72-hour full-load operation debugging before delivery, realizing quick installation and plug-and-play use on the customer’s project site.

We have built a full-gradient product matrix to meet differentiated market demands. Conventional factory circulating water filtration and general wastewater recovery projects can choose our ready-made Ultrafiltration equipment, which features low cost and stable basic performance with short delivery cycle. For projects with special water quality conditions, limited installation space and customized water yield requirements, customers can adopt our one-stop Custom Ultrafiltration System service, where our technical team optimizes pipeline layout, membrane quantity and system configuration according to actual working condition data. Large-scale water plants and centralized water supply stations prefer the batch-produced Professional Ultrafiltration Machine, which adopts assembly line standardized production to guarantee consistent product quality for bulk orders. For printing and dyeing, chemical industry with high organic pollution load, the reinforced hydrophilic Organic Membrane Ultrafiltration System can effectively slow down membrane pollution and reduce daily maintenance frequency. In harsh working conditions such as high temperature and strong chemical corrosion, the wear-resistant Advanced Ultrafiltration Ceramic Membrane becomes the optimal matching solution with longer service life.

The frame and process pipeline of standard systems adopt SUS304 stainless steel as default material; SUS316L stainless steel and anti-corrosion lining are optional for corrosive wastewater environments. The whole ultrafiltration system supports unattended automatic operation, with differential pressure interlock protection, automatic backwashing and timing chemical cleaning functions, greatly reducing manual operation pressure for users. Being the direct manufacturer without intermediate distributors, we can provide customers with scheme optimization, spare parts supply and full-cycle technical after-sales service.

2. Working Principle of Ultrafiltration System Equipment

Ultrafiltration system equipment uses low fluid pressure as the driving force and relies on the microporous structure of membrane components to complete physical interception and material separation, and the mainstream operation mode is cross-flow filtration, which is divided into three core working modes: normal water production, automatic backwashing and regular chemical cleaning.

2.1 Normal Water Production Filtration

Raw water is pressurized by the feed pump and evenly distributed into each group of ultrafiltration membrane elements. The membrane aperture is stably controlled at 0.01~0.1 μm. Water molecules and tiny soluble inorganic ions pass through the membrane wall to form qualified produced water for subsequent production and use. Suspended solids, colloids, bacteria, algae and macromolecular organic pollutants are intercepted on the inner surface of hollow fiber membranes. Most raw water flows tangentially along the membrane surface to form cross-flow scouring flow, continuously washing pollutant deposits to maintain stable membrane flux during long-term continuous operation.

2.2 Timed Automatic Backwashing

Pollutants will gradually accumulate on the membrane surface during operation, leading to the continuous rise of pressure difference between the feed side and the produced water side. When the numerical value reaches the preset alarm threshold, the PLC control system will automatically trigger the backwashing program. Clean produced water is adopted for reverse flushing from the water producing side to the raw water side to peel off the attached dirt and discharge sewage out of the system through the sewage pipeline. The backwashing process lasts for a short time and will not interrupt the overall water supply of the ultrafiltration system.

2.3 Periodic Chemical Circulation Cleaning

Long-term operation will inevitably form organic dirt, biological slime and inorganic scale inside membrane pores. The matched acid-base dosing device of the ultrafiltration system is used for circulating soaking cleaning to remove stubborn pollutants thoroughly, restore the initial flux of membrane elements and extend the service life of core membrane components.
