Enviroquip was formed in 1966 to design and supply equipment for water pollution control, advanced waste treatment, water treatment and sludge handling. Since then, Enviroquip has developed Aeration products and processes to meet the specific requirements of aerobic digestion and holds a number of patents in the area. It has evolved aerobic digestion as the process of choice for the smaller treatment facilities that produce class B sludge. In 1998, the company introduced the SymBio biological nitrogen removal process, which provides a combination of enhanced treatment and energy savings. Enviroquip s equipment is backed by process support that encompasses process calculations, specifications and drawings provided to consulting engineers during the initial design stages. The company maintains its headquarters in Austin, Texas.
