Aerosol spray is a type of dispensing system which creates an aerosol mist of liquid particles. It comprises a can or bottle that contains a payload, and a propellant under pressure. When the container's valve is opened, the payload is forced out of a small opening and emerges as an aerosol or mist. Aerosol spray can
Unlike the rubber bulb dispenser which primarily moved air with a small amount of fluid, modern spray bottles use a positive displacement pump that acts directly on the fluid. The pump draws liquid up a siphon tube from the bottom of the bottle and forces it through a nozzle .
Zep’s vehicle care division developed a program for car wash operators in 2015. Dubbed the Assure Program, the program was intended to make commercial car wash chemical management easier and safer by providing cleaning formulations and dispensing systems that the company advertises as simpler to use and maintain.

With the cooperation of the oil and chemical industry, a 1,300-station infrastructure to supply DEF was prepared by September 2005 in Japan. [ 8 ] In 2007, the United States Environmental Protection Agency (EPA) enacted requirements to significantly reduce harmful exhaust emissions.
Refillable bottle with pump dispenser for liquid soap. A pump dispenser is used on containers of liquids to help dispensing. They might be used on bottles, jars, or tubes. Often the contents are viscous liquids such as creams and lotions. [1] Some are metered to provide uniform usage. Some mix contents from two or more sources prior to dispensing.
Jet-forming dispensing systems are therefore usually operated in the area of lower Weber-numbers. In practice, the calculation of the Weber-number becomes more complicated when fluids with additives are used, which demonstrate a non-Newtonian (i.e. thixotropic) flow behavior and therefore the viscosity during the flow through the nozzle is ...
Microfluidics refers to a system that manipulates a small amount of fluids (10 −9 to 10 −18 liters) using small channels with sizes of ten to hundreds of micrometres. It is a multidisciplinary field that involves molecular analysis, molecular biology , and microelectronics . [ 1 ]
Salt water chlorination is a process that uses dissolved salt (1000–4000 ppm or 1–4 g/L) for the chlorination of swimming pools and hot tubs.The chlorine generator (also known as salt cell, salt generator, salt chlorinator, or SWG) uses electrolysis in the presence of dissolved salt to produce chlorine gas or its dissolved forms, hypochlorous acid and sodium hypochlorite, which are already ...
