Feature-Tec SelfClear® Automatic Backwash Filtration System removes particles from liquid process streams to support continuous production without requiring manual work. The system is equipped with a special back-washing setup for periodic removal of contaminants from the elements to maintain filtration efficiency.

SelfClear® Automatic Backwash Filter System regenerates elements without stopping any equipment or industrial processes, ideal for continuous, high temperature processes.

Working Principle:

As process fluid enters SelfClear® Automatic Backwash Filter System, trapped particles forms a layer of filter cake on the cartridge element. This cake layer traps finer particles. The filtration system continually remove particles until it reaches a set pressure differential value. During backwashing, fluid inlet and outlet valves are closed as compressed gas is introduced, removing trapped impurities to renew filter elements.

System Functions:

Filtration:

SelfClear® effectively filters streams with high levels of impurities and viscosity, removing contaminants up to 1 µm. The system is applicable for natural gas, crude oil refineries and amino resin factories.

Separation:

The high efficiency of SelfClear® Automatic Backwash Filter System is specially suited for recycling of waste materials with its compressed gas drying system, reducing wastage of recyclable materials such as precious metal salts, rare metallic catalysts, activated carbon, titanium and PTA particulates.

Rinsing:

In high precision chemical industries, the removal of impurities means repeated rinsing and stirring so as to achieve total dissolution. SelfClear® Automatic Backwash Filter System combines the dual processes of filtration and rinsing to increase productivity, making it suitable for inorganic minerals, titanium and other chemical industries.

Thickening:

SelfClear® system’s back flushing process combines thickening processes and filtration for effective thickening of additives from centrifugal separation.

Main Features:

• Effectively process materials containing a large content of sticky impurities
• High filtration accuracy
• Fully-closed operation to process corrosive and volatile medium which cannot be manually handled
• Dry cake can be obtained and the device is suitable for recycling filter cake (water content below 20%) with minimum liquid loss
• No residue liquid
