Sludge by-products from the metalworking industry have a high potential for recycling. Prolonged grinding processes can generate large amounts of highly valuable, alloy-rich sludge; consisting of metal powder and cooling lubricants. Inside our VacuDry system, the thermal separation of the liquids (hydrocarbons, eventually water) and solids (metal powder) takes place in an oxygen free atmosphere. This absence of oxygen ultimately eliminates material degradation by oxidation, and self-ignition or explosion risks....
Oil sands or, more technically, bituminous sands, are a type of unconventional petroleum deposit. Oil sands represent a vast wealth of energy reserves for the world rivaling traditional sources in quality, availability and the ability to meet the world`s needs for many years into the future. The technologies for extraction of this resource are increasingly efficient, and WesTech has worked with several companies on the leading edge of these efforts and is a ready partner for new projects and plant upgrades.
Coal Preparation Circuit: Three quarters of American coal is mined east of the Mississippi River. Half of this is “prepared” coal. Coal preparation offers a number of commercial and environmental benefits. These include increased quality and commercial value of saleable coal by achieving 75-80% ash reduction and 15-80% trace element reduction. Cleaned coal reduces transportation costs as well as reduced quantities of combustion ash requiring disposal. Coal preparation can also make marginal coal...
Through the application of cutting-edge technologies, WesTech helps to assure that the byproducts of minerals extraction processes are made inert, reliably contained, and kept from causing environmental damage. Implementation of WesTech tailings processing technology assures that groundwater, surface waters, wildlife, and communities will be protected from tailings dam leaks and levy failures.
Aeration is an effective and low-cost solution to oxidize iron and manganese. It can also provide high-efficiency removal of gases such as hydrogen sulfide, carbon dioxide, methane, and volatile organic carbons, which results in better process performance and/or improvement of taste and odor.
With expertise in water and wastewater treatment, oil/water separation, liquid/liquid and liquid/solids separation, WesTech works closely with professionals in the petroleum and chemical industries. We are able to move fast to provide proven solutions and process infrastructure that keep production up and product flowing.
Groundwater Treatment: WesTech offers a wide variety of equipment for groundwater treatment for potable use. Whether your treatment objective is gas removal, nitrate removal, iron and manganese removal, color removal, softening, or even filtering a source under the direct influence of surface water, WesTech has your solution.
Cracking in a refinery is a process where the long organic chains in oil are broken to produce shorter chain organics that are more valuable than the oil. Fluid catalytic cracking (FCC) has generally replaced thermal cracking of petroleum hydrocarbon feed stocks. FCC produces more gasoline with a higher octane rating. FCC’s byproduct gases are more olefinic and valuable than those produced by thermal cracking.
Coke Wastewater Treatment: Heating coal over 1100 Co in the absence of oxygen produces metallurgical coke. This process provides both heat and carbon (coke) required for iron production. During this process the volatile materials contained in the coal are driven off, leaving coke as the product. Gas produced by coking is withdrawn by means of blowers to recover energy-rich byproducts, including methane. Ammonia stills are the principal means of recovery. Recycled scrubber water is used as a coolant. Scrubber...
Mine backfill is defined as the material used to fill the cavities (i.e., stopes) created by underground mining. Backfilling can be a means to dispose of sludge and/or tailings which may contain hazardous materials and to reduce surface environmental impacts by storing tailings underground. Alternately, backfilling with nonhazardous materials can allow for mining productivity improvements. To these materials are added a variety of fillers such as fly ash, course sand, or gravels along with a binder, such as...
Effective screening of inorganics and removal of grit improves the effectiveness of your downstream processes and the longevity of your equipment. WesTech engineers and manufactures a full line of headworks equipment. Our experience and our service-driven approach help you find the right solutions to get the most out of your headworks. The more debris and grit you can remove, the more efficient your downstream equipment and processes will become. Your wastewater treatment facility will save time and money with...
Source waters with moderate-to-high turbidity and/or organics require pretreatment. WesTech can provide conventional layouts with separate flocculation and clarification, or combination units such as solids contact clarifiers and even high-rate processes that can squeeze into very small footprints. Need soft water? No problem, WesTech does that too.
Filters come in all shapes, sizes, and configurations. WesTech will help you select the right filter. This might include a cluster filter with self-generating backwash, packaged steel tank filters, pressure filters, or even a membrane filter. Selecting filter internals such as underdrains, washtroughs, and media is just as important, and WesTech has more options and expertise than anyone else in the market.
WesTech offers you a comprehensive line of process equipment in the industrial market. Your project will be supported by a reliable engineering team with extensive experience in all types of industrial applications.

Landfills are categorized by regulations in three types: industrial, municipal, and hazardous. Individual landfills may be further differentiated by the types of waste which they accept. All landfills are required to be capped, usually occurring at the end of each day. The cap is typically 6-8” of soil. The cap reduces odor and loss due to wind. At the closing of the landfill, a permanent cap consisting of a membrane and more soil is added. Before the landfilling operation begins, an “impermeable”...
Many times mining, oil and gas exploration, construction, and other activities take place in remote areas of the world. In these cases it is necessary to provide both potable water and treatment of sanitary wastes for the facility. In addition, many of these activities take place in temporary fashion as the sites will either be developed or abandoned at a future date.
Countercurrent Decantation (CCD): Rock passes into a dump hopper and is then transferred to a vibrating grizzly screen. The oversized material is sent to a jaw crusher. The crushed product is combined with the grizzly undersize and the ore is conveyed to the coarse ore bin.
