Although it's commonly found in commercial clay mask preparations, the uses for bentonite clay go far beyond cleaning out your pores: It's used in calamine lotion, to remove impurities from food oils, as a fabric softener in laundry detergent, to form animal feed pellets, and — my favorite — it's the ingredient that causes cat litter to clump.

A coal breaking plant, depicted on a postcard in 1907. A coal breaker is a coal processing plant which breaks coal into various useful sizes. Coal breakers also remove impurities from the coal (typically slate) and deposit them into a culm dump. The coal breaker is a forerunner of the modern coal preparation plant.

Common feedstock used in biodiesel production include yellow grease (recycled vegetable oil), "virgin" vegetable oil, and tallow. Recycled oil is processed to remove impurities from cooking, storage, and handling, such as dirt, charred food, and water. Virgin oils are refined, but not to a food-grade level. Degumming to remove phospholipids and other plant matter is common, though refinement processes vary.

Virginia Polytechnic Institute and State University has been researching for the past four years on making stable biogasoline in current oil refineries. Their focus of the research was the length of time bio-oil’s shelf-life. The use of catalysts was used in order to remove impurities from the processed plant sugars. The researchers extended the time from three months to over a year.

A water fountain or drinking fountain is designed to provide drinking water and has a basin arrangement with either continuously running water or a tap. The drinker bends down to the stream of water and swallows water directly from the stream. Modern indoor drinking fountains may incorporate filters to remove impurities from the water and chillers to reduce its temperature. In some regional dialects, water fountains are called bubblers.

Electrorefining technology converting spent commercial nuclear fuel into metal. Electrowinning, also called electroextraction, is the electrodeposition of metals from their ores that have been put in solution via a process commonly referred to as leaching. Electrorefining uses a similar process to remove impurities from a metal. Both processes use electroplating on a large scale and are important techniques for the economical and straightforward purification of non-ferrous metals.

Organic scavenger resins have been used commercially in water filters as early as 1997. As an alternative to reverse osmosis, organic anion resins (scavenger resins) have been used to remove impurities from drinking water. These types of resins are able to remove the negatively charged organic[verification needed] molecules in water, like bicarbonates, sulfates, and nitrates. It has been estimated that 60–80% of organic impurities in water may be remove using these methods.

By the 1930s the mill had largely achieved the configuration it exhibits today. Sorghum stalks were sent down a conveyor belt at the uphill, east-end of the complex and crushed in a three-cylinder roller mill. The juice crushed out of the stalks flowed into three defecation tanks, where it was heated with steam to remove impurities. From there the juice flowed into an evaporator trough, where it was boiled down into syrup.

An integrated gasification combined cycle (IGCC) is a technology that uses a high pressure gasifier to turn coal and other carbon based fuels into pressurized gas—synthesis gas (syngas). It can then remove impurities from the syngas prior to the power generation cycle. Some of these pollutants, such as sulfur, can be turned into re-usable byproducts through the Claus process. This results in lower emissions of sulfur dioxide, particulates, mercury, and in some cases carbon dioxide.

Company chemists later resolved this issue by installing a filtration system to remove impurities from the manufacturing plant's water system. In the 1960s, the soda's regional popularity expanded when the company began advertising during broadcasts of Detroit Tigers games. With the Tiger ads reaching beyond Faygo market area at the time and inability to cancel the ads, Faygo shipped products to the wholesalers' warehouses. This increased company sales from $6 million in 1966 to $20.4 million in 1971.

With the advent of coinage, methods had to be invented to remove impurities from the gold so that gold of specific purities could be made. Cupellation was able to remove gold and silver from mixtures containing lead and other metals, but silver could not be removed. Gold parting as a process was specifically invented to remove the silver. The main ancient process of gold parting was by salt cementation and there is archaeological evidence of that process from the 6th century BC in Sardis, Lydia.

By 1949 more sophisticated techniques were being employed to remove impurities from gas, and the tower was no longer used. With the availability of natural gas to Brisbane in the 1970s, the company's Montague Road works were made redundant and in 1975 most of the structures on the site were demolished. In the same year the stripping tower was acquired by the National Trust of Queensland, who dismantled the structure and stored it pending availability of a suitable relocation site. In 1979, it was reassembled in Davies Park, approximately from its original position.

The common valve spring system is satisfactory for traditional mass- produced engines that do not rev highly and are of a design that requires low maintenance.Rivola, A., et al.: "Modelling the Elastodynamic Behaviour of a Desmodromic Valve Train", Proceedings of SMA2002 International Conference on Noise & Vibration Engineering,16–18 September 2002 - Leuven, Belgium At the period of initial desmodromic development, valve springs were a major limitation on engine performance because they would break from metal fatigue. In the 1950s new Vacuum melt processes helped to remove impurities from the metal in valve springs, increasing their life and efficiency greatly.

There is an ion exchange system included in the loop to remove impurities from the feedwater. The turbine consists of one high-pressure rotor and four low-pressure ones. Five low- pressure separators-preheaters are used to heat steam with fresh steam before being fed to the next stage of the turbine. The uncondensed steam is fed into a condenser, mixed with condensate from the separators, fed by the first-stage condensate pump to a chemical purifier, then by a second-stage condensate pump to four deaerators where dissolved and entrained gases are removed; deaerators also serve as storage tanks for feedwater.

An air purifier or air cleaner is a device which removes contaminants from the air in a room to improve indoor air quality. These devices are commonly marketed as being beneficial to allergy sufferers and asthmatics, and at reducing or eliminating second-hand tobacco smoke. The commercially graded air purifiers are manufactured as either small stand-alone units or larger units that can be affixed to an air handler unit (AHU) or to an HVAC unit found in the medical, industrial, and commercial industries. Air purifiers may also be used in industry to remove impurities from air before processing.

ISCO is accomplished by injecting or otherwise introducing strong chemical oxidizers directly into the contaminated medium (soil or groundwater) to destroy chemical contaminants in place. It can be used to remediate a variety of organic compounds, including some that are resistant to natural degradation #Bioremediation is a technique that uses microorganisms in order to remove or extract certain waste products from a contaminated area. Since 1991 bioremediation has been a suggested tactic to remove impurities from water such as alkanes, perchlorates, and metals. The treatment of ground and surface water, through bioremediation, with respect to perchlorate and chloride compounds, has seen success as perchlorate compounds are highly soluble making it difficult to remove.

The ability to remove impurities from the air passing through the filtration media is largely dependent on how long the air remains in contact with the media while passing through the filter stack, known as dwell time. A longer dwell time in the filter is an effective way of increasing contact time, and this is proportional to the pressure of the air in the filter housing. By using a back pressure valve the air always takes approximately the same time to pass through the filter and filtration is consistent (assuming a consistent operating speed). The back-pressure valve is usually set to near the working pressure of the compressor to ensure that the air is compressed sufficiently for the filters to work effectively.

It is part of an extensive selection of images of neon lighting; see Claude's associate, Jacques Fonsèque, realized the possibilities for a business based on signage and advertising. By 1913 a large sign for the vermouth Cinzano illuminated the night sky in Paris, and by 1919 the entrance to the Paris Opera was adorned with neon tube lighting. Over the next several years, patents were granted to Claude for two innovations still used today: a "bombardment" technique to remove impurities from the working gas of a sealed sign, and a design for the internal electrodes of the sign that prevented their degradation by sputtering. In 1923, Georges Claude and his French company Claude Neon introduced neon gas signs to the United States by selling two to a Packard car dealership in Los Angeles.

Huntsman had already been using various fluxes to help remove impurities from steel, and soon began adding a manganese-rich pig-iron called Spiegeleisen, which greatly reduced the presence of impurities in his steel. In 1816, a German researcher Carl J. B. Karsten Ludwig Beck Die Geschichte des Eisens in Technischer und kulturgeschichtlicher Beziehung Page 31-33 noted that adding fairly large amounts of manganese to iron would increase its hardness without affecting its malleability and toughness, but the mix was not homogeneous and the results of the experiment were not considered to be reliable. "and no one understood that the real reason why the iron mined in Noricum produced such superb steel lay in the fact that it contained a small amount of manganese uncontaminated by phosphorus, arsenic, or sulphur, and so was the raw material of manganese steel."Colleen McCullough (1990), "steel", in "Glossary", The First Man in Rome, 1991 reprint, New York: Avon, p. 1030. In 1860, Sir Henry Bessemer, trying to perfect his Bessemer process of steel making, found that adding spiegeleisen to the steel after it was blown helped to remove excess sulfur and oxygen.
