Mazzei Injector Company, LLC applications

Wastewater in sewer mains can become septic due to low flow rates or long-distance runs. Odors and highly toxic, corrosive hydrogen sulfide gas are some of the problems created in septic conditions. The addition of oxygen to sewer mains can prevent or reverse septic conditions by creating an aerobic environment.

Mazzei venturi wastewater aeration technology is ideal for introducing air or oxygen into lift stations and sewer mains. A sidestream of wastewater is pumped directly from the sewer main (or from a basin with a lift station pump) through one or more Mazzei^® venturi injectors that aspirate either ambient air or concentrated oxygen with no need for blowers or compressors. 

The growing demand placed on the world’s water, in combination with more stringent water quality regulations, have placed unprecedented demands to provide safe, reliable and aesthetically pleasing drinking water. Air stripping is an effective way of removing volatile organic chemicals (VOCs) from contaminated water and is commonly used for this application. Air stripping systems mix air with a water supply with the goal to generate the largest possible air-water contact area so that VOCs and dissolved gases, such as radon and hydrogen sulfide, will move from the water to the air. In addition to removing VOCs, air stripping is primarily used for removing oxidizing contaminants such as iron and manganese, improving taste, or removing odor. Air stripping is an EPA Best Available Technology (BAT) for some VOCs including benzene, toluene, xylene, tri/tetrachloroethylene, trihalomethanes, vinyl chloride and many others.
