D.FITE Cloth Filter

The ONYX-D.FITE cloth filter series is suitable for installation in civil engineering water tanks.

This fine filtration technology, developed based on fiber filter cloth, boasts high filtration accuracy, excellent filtration performance, minimal auxiliary equipment, and low head loss. Its advantages include high filtration precision, excellent filtration efficiency, minimal auxiliary equipment, and low head loss. It is widely used in wastewater advanced treatment, circulating water filtration, and pre-treatment for advanced treatment processes.

The external-inlet, internal-outlet fiber disc filter consists of a series of horizontally mounted rotating filter discs fitted with easily removable filter cloths with a pore size of 10 μm.

The fiber disc filter operates in various modes: filtration, backwashing, and sludge removal.


Advantages

Non-stop backwashing

Backwashing involves two filter discs in a set. The entire set of filter discs continues filtering during backwashing, allowing for 24-hour continuous operation to maximize wastewater treatment capacity.

Excellent and stable water quality

The filter uses a woven fiber plush cloth with an average mesh diameter of ≤10 microns and an effective filtration depth greater than 3mm. Solid particles are fully contacted with the cloth within the effective filtration depth, while oversized particles are captured by the cloth, resulting in excellent water quality after filtration.


Easy Installation and Maintenance

The cloth filter system utilizes a sector-shaped disc assembly that can be quickly and easily secured to the central shaft for installation and disc replacement and maintenance.

Low Head Loss

The total head loss of an SCDF cloth filter system is generally less than 0.7 m, eliminating the need for secondary lifting, reducing water plant investment and operating costs.

Automatic Control and the Internet of Things

The entire process is controlled by a central control system. Once parameters are set, the system automatically runs, achieving a high degree of automation. This allows for unattended operation. Connecting to a host computer displays real-time operating status. PC and mobile client applications are supported for viewing device status and providing real-time device information.
