1. Product Introduction for Wholesale of Ultrafiltration Equipment

We are a professional manufacturer supporting bulk wholesale of ultrafiltration equipment, equipped with large-scale standardized production workshops, membrane performance testing labs, automatic welding production lines and finished product offline debugging areas. All core components including PVDF ultrafiltration membrane elements, stainless steel frames, pipeline fittings, pump valves and PLC control cabinets are self-produced and inspected in-house, so we can guarantee stable stock supply for regular wholesale orders and flexible customization for large project bulk orders without middleman markup.

For different wholesale customer groups and application environments, we have categorized standardized wholesale ultrafiltration products. For wastewater concentration, material separation and high-pollution sewage treatment projects undertaken by engineering companies, Concentrated Ultrafiltration Membrane Equipment is the mainstream wholesale model, with optimized membrane module layout to boost pollutant load capacity and concentration efficiency. For high-standard water production links such as pharmaceutical purified water and electronic ultrapure water pretreatment, Dual Stage Ultrafiltration Equipment is supplied in wholesale batches, adopting two-stage graded interception to thoroughly remove tiny colloids and microorganisms to improve water outlet safety. For small commercial water stations, laboratory water supply and small factory water renovation projects, our hot-selling wholesale product Compact Small Scale Ultrafiltration Membrane Equipment features integrated assembly, small floor area and plug-and-play installation, greatly reducing the installation workload for downstream wholesalers’ end customers. For municipal reclaimed water plants and large industrial park centralized water supply projects requiring bulk bidding procurement, Complete Ultrafiltration Equipment is delivered as a whole set after factory pre-assembly and full-function testing, lowering on-site construction difficulty for engineering purchasers.

All wholesale ultrafiltration equipment adopts modified anti-fouling PVDF hollow fiber membranes with outstanding acid, alkali and oxidation resistance. Standard wholesale configurations adopt 304 stainless steel brackets, while 316 stainless steel and anti-corrosion plastic materials are available for customized wholesale orders facing corrosive wastewater. The built-in PLC automatic control system supports differential pressure monitoring, automatic backwashing and timed chemical cleaning, realizing unattended 24-hour operation. In terms of wholesale cooperation mode, we support spot bulk wholesale for distributors, project bidding bulk supply for engineering companies, as well as personalized color, logo and structural OEM wholesale services.

2. Working Principle of Wholesale Ultrafiltration Equipment

All ultrafiltration devices provided by our wholesale business adopt mature pressure-driven cross-flow filtration technology, circulating between normal water production filtration state and membrane cleaning regeneration state.

Normal Filtration & Water Production

Raw water is pressurized by the feed pump to 1.0–3.6 bar and flows into the ultrafiltration membrane assembly. The membrane wall has uniform micropores of 0.01~0.1 μm, water molecules and small soluble inorganic substances pass through the membrane smoothly to form qualified produced water for production usage. Suspended solids, colloids, bacteria, algae and macromolecular organic pollutants are trapped on the outer surface of hollow fiber membranes. Partial fluid flows rapidly along the membrane surface to form cross-flow concentrated water, continuously scouring most intercepted pollutants away to prevent dense filter cake accumulation on the membrane surface.

Automatic Membrane Cleaning & Regeneration

After long-time continuous operation, partial pollutants will adhere to the membrane surface and cause flux attenuation. The default program of wholesale standard equipment will automatically activate two cleaning modes: regular backwashing uses clean produced water for reverse flushing to strip loose surface contaminants; periodic CIP chemical cleaning dissolves biological slime and organic fouling through matched medicaments, restores the original flux of membrane components and ensures long-term stable water output efficiency of the equipment.
