Welcome to Mass Transfer Systems

Since 1984, Mass Transfer Systems (MTS) has been supplying jet aeration and mixing systems to industries and municipalities throughout the world. The majority of our product consist of "engineered systems" for biological and other waste treatment processes and a variety of industrial mixing applications.

In 1995, MTS began offering a product line of submersible self-aspirating aerators to provide oxygen for both municipal and industrial biological and waste treatment processes. The submersible self-aspirating aerator does not require a forced air system (i.e blowers) and is easily installed into existing treatment tanks with little or no modification.

As with the jet aeration systems, there is no project too large or too small for Mass Transfer Systems jet mixing systems.

Aspirator Submersible Aspirator

MTS Aspirator

The MTS Aspirator provides oxygen transfer by aspirating the ambient atmospheric air, thus negating the need for air blowers. This easy to install, portable, dependable aerator has been utilized in multiple applications such as; sludge holding tanks, aerobic digesters, activated sludge tanks, storage tanks, equalization basins, stormwater basins, and post-aeration applications.

Floating Effluent Decanters
