Selecting the best air mover for a bulk-solids pneumatic-conveying application is a critical design decision. Provided here is information on three classes of air movers when dilute-phase pneumatic conveying is required In a typical bulk-solids pneumatic-conveying system, an air mover is used to generate the necessary air flowrate and pressure required to transport a solid material through a specific pipeline distance at a given rate. Designing a successful pneumatic conveying system depends on specifying the correct air mover, in terms of volumetric flowrate, pressure and motor size. A wide range of machines is potentially capable of meeting the requirements of the duty. However, not all air movers are suited to pneumatic conveying applications. Therefore, understanding the design and operating characteristics of various air movers is the key to successfully selecting the right machine. This article discusses the operating mechanisms and characteristics of three different types of air movers for dilute-phase pneumatic conveying: centrifugal fans and blowers; regenerative blowers; and positive-displacement (PD) blowers. Numerous air movers are available on the market for dilute-...

Hazardous Waste Treatment Market Opportunity Assessment By Top Players Forecast

Growth in instances of detection of toxic chemicals in polar ice caps, drinking water supplies, and groundwater sources have shifted the focus of the public and environmental regulatory authorities around the globe on the health and environmental risks from inappropriate disposal methods of hazardous waste into the environment. Accumulation of large quantities of hazardous wastes around the globe is attributed to the rise in hospital waste generation and rapid urbanization in developing countries. Major industries responsible for the production of hazardous wastes globally include pharmaceuticals, petrochemicals, fertilizers, paints & dyes, pesticides, petroleum, asbestos, and inorganic chemicals. Most common toxic materials found in hazardous wastes are cyanides, heavy metals, complex aromatic compounds, pesticides, and others with high toxicity, flammability, reactivity, and corrosiveness. Discharge of hazardous waste in open without treatment results in acidic and alkaline chemical seepage into potable water aquifers and fertile soils. This degrades the quality of the soil and makes fresh water aquifers unusable. Treatment of hazardous wastes can be carried out by convert...
