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.
WesTech leads the way in municipal sedimentation solutions for primary and secondary clarification. Customers around the world benefit from the Clarifier Optimization Package (COP), which provides clean effluent, maximizes overflow rates, and optimizes underflow concentration.
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 treated water is suitable for many agricultural and industrial uses. However, it will...
Due to its ion exchange, flocculation, and sedimentation properties, bentonite is used in environmental protection for water clarification and sludge treatment. In water treatment systems, bentonite is a mineral type of clarifying agent, just like aluminium chlorohydrate, aluminium sulphate, ferrous sulphate, and iron chloride. However, since it is not soluble, it is the only agent capable of forming suspensions that remain stable over time. Further, bentonite “captures” metal pollutants, through an...
Kurita specifically developed product ranges for drinking water treatment, in order to avoid any kind of problem that might occur with the preparation, transport or use of drinking water. Our technologies can be used for all kinds of conditions, from municipal water suppliers to private buildings (e.g. hotels, universities, hospitals and private homes).
Acid mine drainage (AMD) is typically characterized by low pH and high dissolved iron. The acid mine drainage may also contain high amounts of CO2 which forms carbonic acid and further depresses the pH.
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...
Malodors can commonly be the by-prodcut of many industrial and manufacturing processes. Oil refineries and petrochemical plants may generate large volumes of odor from the processing and refining of different fuels. Sulfides, mercaptans, and hydrocarbon compounds are all closely related to the petro-chemical industry. The odors generated from these industrial compounds are of a high nuisance value and generally create concern among local air boards and the public communities which surround these plants.
The product knowledge we gained by this experience is indicated by the following list of products suitable for processing on a GEA Filtration membrane filtration system. These systems include microfiltration, ultrafiltration, nanofiltration, and reverse osmosis with either spiral-wound, stainless steel, ceramic, tubular, or plate-and-frame configurations.
Safely Eliminate Odors Created By Food Processing: Malodors generated by the food processing industry vary enormously since they can be generated in the production, processing, and wastewater treatment areas of the plant. Regardless of the source, all of these odors may be offensive to the public.
