When plant engineers are tasked with selecting and specifying chemical metering pumps, the two common choices that come to mind are either a reciprocating plunger pump or a diaphragm pump. Gear pumps typically are seldom considered as conventional metering pumps have almost become synonymous with reciprocating pumps. Conventional metering pumps, …
The steel industry is a harsh environment where all equipment is exposed to intense heat and must operate reliably to prevent dangerous situations. Part of the steel finishing process includes pickling, which is a method of removing impurities from steel such as inorganic contaminants, scale, rust, stains, aluminum alloys, and …
Ultrafiltration of water is an important process in many industries and applications, treating water for reuse by removing particles and contaminants. Depending on the water source and the ultimate requirement for water quality, industrial pumps and process equipment perform a series of processes such as water intake, aeration, flocculation and …
Industrial water treatment is necessary for many processes such as boiler water treatment, water cooling towers, chemical manufacturing, paints, pulp, and paper manufacturing, and many other applications. Water is a vital natural resource and different industrial uses require different water treatment options based on the process, the water source, and …
Removing particles through an ultrafiltration water treatment process is a key component in providing clean water for subsequent use. Water filtration pumps are used to pump water through a membrane that removes particles as small as 0.01 μm, or microns, such as suspended solids, bacteria, and other small particles. Ultrafiltration …
Variable frequency drives (VFDs) adjust the pressure or flow on pumps to meet the actual demand. VFDs control the frequency of electricity delivered to pumps and fans. VFDs can provide significant power savings by controlling the rotational speed and frequency of electrical power supplied to the pump motor. VFDs are …
Diaphragm metering pumps provide precision and accurate dosing to many applications that require consistent flow. While precision and accuracy are very similar definitions referring to the quality of a measurement, they provide different indications. Precision refers to the degree to which a process or instrument will repeat the same value, …
Industrial wastewater treatment programs are required to meet national guidelines established by the Environmental Protection Agency, EPA, regarding the discharge of industrial wastewater and the level of contaminants allowed. The EPA established Effluent Limitation Guidelines (ELGs) as part of the Clean Water Act of 1972 which limits the maximum contaminant …
Precise and accurate control of dosing flavorings, essence, fragrances, or any other food additive is key to high product quality. Any slight alteration of a flavorant can significantly alter the characteristics of a food or beverage product causing it to become too sour, sweet, or tangy. Different additives can change …
Water cooling towers are used in various industrial processes to cool process equipment such as machinery and presses, chillers, and air-conditioners to prevent overheating and maintain an ambient air temperature. Water leaves the cooling tower in a few different ways, mostly through evaporation. A small amount of water may leave …
