Candle filter is a self-cleaning filter specially designed for solid-liquid separation, typically used for the clarification and recovery of liquids with low solids content from 5 % to less than 1 % or even trace amounts of solids.
Filter housing is made of stainless steel, special materials are available upon request;
Fully closed operation, which makes it capable of handling corrosive and volatile liquids without doing harm to the environment and employees' health;
Filter aid may be added as needed;
No residual liquid design; at the same time, the filter cake can be dried, which is suitable for processing and recycling filter cakes with minimum liquid loss.
Filter aids are available in a variety of materials to meet diversified filtration demands of all industries.
Structure:
Candle filter is composed of a filter housing, filter bags, filter elements, registers, a computer control system, accessor
ie, etc.
The filter housing is provided with instrument connection nozzle, air vent, inlet nozzle, discharge nozzle, inspection hole, etc.
Candle filter consists of multiple combined filter elements inside. Every filter element is composed of 6 porous metal tubes and a central tube and then covered with a filter bag. The filter bag is selected according to the characteristics of the raw material liquid. Filter aids are required when filtering some special raw material liquids, such as activated carbon, diatomaceous earth, etc. Filter elements are used to support filter bags, and all filter elements are connected to the register at the top of the filter.

Candle filters are mainly used to purify liquids with low solid content and recover expensive materials from them. They are widely used in the following industries.
Pharmaceuticals. Biological and plasma products filtration, compressed air and gas filtration, catalyst recovery filtration;
Food & beverage. Fermented beer filtration; edible oil bleaching & filtration, edible oil dewaxing or antifreeze oil filtration and catalyst recovery filtration, decolorizer and activated carbon filtration;
Oil & gas. Crude oil mercury removal & filtration, gas desulfurization, sulfur recovery, etc.
Environmental protection. Power station flue gas desulfurization, incineration waste gas disposal, waster toxic chemical precipitation & filtration, etc.
Mining. Catalyst recovery & filtration, aluminum recovery washing water filtration, filtration in lithium and nickel production.
