In primary clarification, a portion of the suspended solids and organic matter is removed from the wastewater. This removal is usually accomplished with physical operations such as sedimentation. The effluent from primary clarification will ordinarily contain organic matter and have notable BOD. The principle function of primary clarification is to be a precursor to secondary clarification. Following primary clarification, the...

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.
Bottom Ash Pond Replacement: When coal is burned, two major forms of ash are produced. The fly ash is light and leaves the furnace with hot gases. The bottom ash is heavy and stays in the furnace until it is scraped out. Due to potential liability issues and/or the need to find new real estate at power plants for expansion, many utilities must replace their traditional coal ash ponds. Utilities using traditional...
Cold Lime Softening:Hard water is water that has high mineral content. The name comes from the hard scale that forms when this water is boiled. It is not harmful to human health, but in the industrial setting it causes costly breakdowns in boilers, cooling towers, and other water handling equipment. The divalent cations Mg and Ca are the most frequently found minerals causing hard water. These ions...
Heavy Metals Wastewater Treatment System (Chrome Removal): Chromium is present in the wastewaters of a number of industries, including: stainless steel manufacturing, protective coatings on metal, magnetic tapes, chrome plating, tanneries, textile dyes production, pigments and paint production, production of cement, paper, rubber, etc. Chromium is typically precipitated in two steps: reduction and precipitation....
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...
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.
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...
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...
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...
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.
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.
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...
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.
The advantages of paste thickeners in tailings circuits have been well-established for most minerals. The type of paste thickener underflow generally used for surface stacking of tailings is called “thickened tailings.” Thickened tailings are a suspension of solids which are relatively non-settling and non-segregating and which have a higher concentration and viscosity than that of conventional tailings. Common...

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.
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.
