The suspension and aeration are typically provided by an air pump, which pumps air through the aeration chamber, providing a constant stirring of the wastewater in addition to the oxygenation. A medium to promote fixed film bacterial growth may be added to some systems designed to handle higher than normal levels of biomass in the wastewater.
Maceration can be achieved by using a chopper pump in the sewage lift station or at the wastewater treatment plant. [ 1 ] When the flush is triggered, wastewater flows into the macerator, and when the water level rises, pressure activates the unit, causing the stainless steel blades to rotate at 3,600 rpm, pulverizing the wastewater into fine ...

A Med-E-Jet vaccination gun from 1980. A jet injector, also known as a jet gun injector, air gun, or pneumatic injector, is a medical instrument that uses a high-pressure jet of liquid medication to penetrate the skin and deliver medication under the skin without a needle. Jet injectors can be single-dose or multi-dose.
Crosman claims a pellet velocity of up to 600 ft/s (180 m/s) from a gun pumped ten times, which is higher than that achieved by most pellet pistols of any kind. Many 1377 owners report success with only a few pumps, and the lower velocity is accompanied by lower noise, often an advantage for those shooting indoors.
This air gun was to fill the gap between the "BB" gun and the .22 caliber. A successful prototype was produced mid-1944 and in 1945, in partnership with I.R. "Bob" Kraus, Sheridan Products Inc. was born in Racine, Wisconsin . [ 1 ]
A para-athlete competing with a match air rifle A collection of lever-action, spring-piston air rifles. An air gun or airgun is a gun that uses energy from compressed air or other gases that are mechanically pressurized and then released to propel and accelerate projectiles, similar to the principle of the primitive blowgun.
