Electricity-free Ultrafiltration Equipment

General Product Description:
The adaptive "Electricity-free" Ultrafiltration Water Purification Equipment integrates the anti-fouling technology of the Furui™ free-end ultrafiltration membrane series with the mechanism of a valveless filter. It relies on the incoming water head difference to provide the transmembrane pressure required for water production, while using transmembrane compression as the cleaning threshold and siphon principle to achieve periodic automatic backwashing.

Core Advantages

No Electricity Required

The entire water purification equipment operates without any electrical power during the whole cycle.

Electricity-free Ultrafiltration Equipment 3

Automatic Operation

Follows an automatic cycle of water production → cleaning → discharge, requiring no manual supervision.

Electricity-free Ultrafiltration Equipment 4

Self-Adaptive

Automatically adjusts the cleaning and discharge frequency according to raw water quality, ensuring easy maintenance.

Flexible Assembly

Can be freely assembled according to on-site conditions and flexibly combined with pre-treatment and post-treatment processes.

Product Features

Integrated, modular and standardized design and production, featuring short construction period and convenient transportation.

Automatic production-water cleaning cycle operation, with low failure rate, low maintenance cost, unattended operation and no need for automatic control system.

Installation same as the public version of membrane shell on the market.

All-stainless steel structure, can be placed outdoors, sturdy and durable.

Antimicrobial PVDF hydrophilic alloy membrane pore is uniform and fine, which makes anti-pollution ability is stronger.

Adaptive cleaning system that automatically adjusts cleaning frequency according to water quality, reducing overall system operation and maintenance costs.

Optional additional units such as water quality monitoring system and intelligent dosing system can be flexibly assembled according to requirements.

Socket structure design, offline cleaning more convenient

Product Application

Suitable for water supply in mountainous areas, islands, and other harsh environments where access to electricity is limited, civil construction costs are high, and transportation and installation are challenging.
