About Liquid Filters

Liquid filters are mechanisms that are used to remove impurities that occur in liquids both from natural and unnatural sources. In order to achieve the filtration process, a liquid is passed through a permeable or porous substance that lets the liquid pass through while catching the larger solid particles that need to be removed. For the liquid to flow there must be a pressure difference that causes it to move through the filter. Usually, liquid filters are used to clean or purify a product or extend the life of piping by removing corrosive materials that induce erosion. Liquid filters have also been used to remove bacteria from certain liquids to prevent spoiling and, in other cases, to remove harmful particles so that the liquid may be recycled and reused.

Water filters are the most common type of liquid filters. They use semi-permeable filtering elements that allow water molecules to pass through the liquid filters, while hindering water soluble elements such as lead, chlorine and salt, among others. Carbon is the most popular type of liquid filter element that is used in water filters. It has a very good performance record for removing most water soluble imperfections. Water filters are popular for personal home purification purposes because removing unwanted sediment matter results in higher quality, better tasting water.

Liquid filter manufacturers offer various types of products to serve particular purposes. For instance, high-flow filtration systems are used for situations that have a high amount of particulate, water count or acid, while low-flow filtration systems are used for the opposite reasons. Bearing filtration systems are able to keep the filtered lubrication oil clean and, in effect, extend the life and effectiveness of the oil, while maximizing its performance. Additionally, vacuum dehydration systems use vacuums to move liquid through the liquid filters at a high flow rate. Liquid filter manufacturers use various types of membranes in their products, which also vary greatly by application. A microfiber is able to provide a high retention of small particles, similar to felt, which is good at removing particles of many different shapes and sizes. Multi-filament mesh is an inexpensive woven substance that is very good for sifting coarse particles.

Many factories are required to utilize liquid filter manufacturers to keep waste water within federal guidelines. Some industries that use liquid filters include textile mills, cosmetics, food and beverage, electronic components, tool manufacturers, ship builders, pulp and paper mills, foundries, air conditioning and oil and gas wells. Picking the liquid filters with the correct amount of permeability is critical. How permeable the filter media is determines what size particles are able to make their way through the filter downstream. Different permeabilites result in varying flow rates. Picking the correct filtration system can mean choosing between a higher rate but less filtered unit and vice versa. Other important considerations include whether the filtration system will impact productivity in a negative way and if the short- and long-term associated costs are reasonable.

Types of Liquid Filters

• Bag filters are receptacles that liquid is passed through to remove impurities.
  
• Carbon filters are filters that contain carbon in their solid state. They use absorption to remove unwanted soluble substances from water and can be found in many applications, including personal water filters and purifiers.
  
• Cartridge filters have a receptacle that holds the filter media.
  
• Chemical filters are used to remove chemicals with a carbon filter.
  
• Filter media is the material through which liquid is passed to remove all particles and impurities.
  
• Fuel filters are designed to filter sediments from fuel supplies because particulates are harmful to engines and can significantly decrease engine life.
  
• Industrial water filters remove impurities from water in industrial settings.
  
• Pleated (convoluted or corrugated) filter elements consist of a number of uniform folds and generally have a geometric shape, such as a cone, cylinder, plate or others.
  
• Reverse osmosis filters are filter elements used in reverse osmosis applications. Reverse osmosis is a process that uses pressure to move water molecules through a membrane; the impurities that remain behind are then discharged in a waste stream.
  
• Strainers are used in filtration systems to remove large particles.
  
• T-type filters have both inlet and outlet ports situated at one end. The ports of their major axes are in a straight line with the axis of the filter element perpendicular to the line.
  
• Water filter systems are complete units that begin with a “dirty” water source and result in a purified end product. In the system, unpurified water is filtered and then acquired as a “clean” product.
  
• Wet/dry filters have filter elements that are designed to filter particle matter from both air and water. They can be found in wet/dry vacuum cleaners and fish aquariums.
