Filtration

Industrial Liquid & Gas Filtration Technologies

Filtration is a critical separation process that removes solid particles, contaminants, and impurities from liquids or gases using various filter media. Different types of filtration systems are chosen based on particle size, flow rate, viscosity, and application requirements.

Common Industrial Filtration Types

Type Description Best Applications
Bag Filtration Flexible fabric bags housed in a vessel that capture particles as liquid flows through. Coolants, paints, inks, wastewater, food products
Cartridge Filtration Cylindrical cartridges with pleated or wound media for high surface area and fine filtration. Pharmaceuticals, chemicals, water treatment, oils
Candle Filtration Vertical tubular elements (candles) used for high-pressure, fine particle removal. Polymers, resins, catalyst recovery, beverages
Pressure Leaf Filtration Horizontal or vertical leaves coated with filter aid for large-volume batch filtration. Edible oils, chemicals, pharmaceuticals
Coalescer Filtration Specialized media that merges tiny droplets of one liquid into larger ones for easy separation. Oil-water separation, fuel filtration, compressed air
Filter Press Filtration High-pressure plate-and-frame system that forms thick filter cakes for dewatering. Sludge dewatering, mining, wastewater, chemicals
Self-Cleaning Filters Automatic backwashing or scraping systems that clean themselves during operation. Continuous processes, high-flow applications, cooling water
Bag Filtration

Bag
filtration

Bag Filters are flexible fabric filtration systems used to capture dust, particulates, and solids from air or liquid streams. The contaminated fluid flows through porous filter bags, trapping particles inside while clean fluid passes through. They are widely used in industrial dust collection, wastewater treatment, chemical processing, and food industries due to their high efficiency, large dirt-holding capacity, and cost-effectiveness.

Cartridge Filters

Cartridge Filters are cylindrical filtration units designed to remove fine particles, sediments, and contaminants from liquids and gases. The fluid flows through a pleated or wound filter media housed in a cartridge, capturing particles down to sub-micron levels. They are widely used in water treatment, pharmaceuticals, chemicals, food & beverage, and oil filtration for their high efficiency, compact design, and easy replacement.

Candle Filters are vertical, tubular filtration systems used for high-efficiency clarification of liquids. The filter candles, made of porous ceramic, sintered metal, or woven fabric, trap particles on their outer surface while clean liquid flows inward. They are ideal for polishing, catalyst recovery, and fine filtration in chemical, pharmaceutical, and food industries due to their excellent clarity and long service life.

Vertical Pressure Leaf Filter

pressure leaf filtration

Pressure Leaf Filters are highly efficient, horizontal or vertical pressure vessels equipped with multiple filter leaves. Liquid is pumped under pressure through the leaves, where solids build up as a filter cake on the cloth surface. They offer large filtration area, excellent cake washing and drying, and high throughput. Ideal for chemical processing, edible oil refining, pharmaceuticals, and sugar industries.

A Magnetic Strainer is an advanced filtration device that combines a traditional basket strainer with powerful permanent magnets. It effectively removes both large debris and fine ferrous particles (down to 1 micron) from liquids. Ideal for protecting pumps, valves, and machinery in hydraulic systems, lubricants, fuels, and process fluids, magnetic strainers reduce downtime and extend equipment life.

coalescer
filtration

Coalescer Filters are specialized separation systems designed to remove finely dispersed liquid droplets (such as water or oil) from another immiscible liquid or gas stream. Using special coalescing media, small droplets merge into larger ones, which then separate by gravity. They are widely used in fuel filtration, compressed air systems, oil-water separation, and natural gas processing for high-efficiency liquid removal and product purity.

SELF-CLEANING filtration

Self-Cleaning Filtration systems automatically remove accumulated dirt, debris, or cake from the filter media without interrupting flow. Using backwashing, mechanical scraping, or rotating mechanisms, these filters maintain consistent performance and reduce downtime. They are ideal for continuous industrial processes such as cooling water, wastewater treatment, food processing, and high-flow applications where manual cleaning is impractical.

Horizontal Filter Press

Filter Press Filtration is a highly effective batch separation process that uses pressure to force liquid through a series of filter plates and cloths. Solids accumulate as filter cake between the plates while clear filtrate is collected. It delivers excellent dewatering, high solid recovery, and dry cake discharge. Widely used in wastewater treatment, mining, chemical, and food industries for sludge dewatering and solid-liquid separation.

magnetic bag filtration

Magnetic Bag Filtration is an innovative hybrid system that combines the high dirt-holding capacity of bag filtration with powerful magnetic separation. It effectively removes both ferrous particles using strong neodymium magnets and non-ferrous contaminants through the filter bag in a single pass. This dual-action technology provides superior protection for pumps and equipment while extending filter bag life in industrial fluid systems.
