Schreiber LLC traces its roots back to the 1930s, when Dr. August Schreiber began researching and developing innovative biological purification methods in Germany. Within a few years, Dr. Schreiber’s small mechanical plants dotted the countryside. Schreiber-Klaranlagen was established in 1959 in Hanover, Germany, developing products for mechanical-biological “package” treatment plants. In 1969, after extensive research and development, Schreiber’s innovative Counter Current Aeration technology led to the building of the first activated sludge plant. When it comes to wastewater treatment, Schreiber’s philosophy has always been “Improving Water Through Technology”. Today our focus is simple: We improve wastewater. How we do it is pure ingenuity. With installations at more than 2,000 water treatment facilities worldwide.

About us

In 1979, Schreiber established Schreiber Corporation in the United States, with facilities in Trussville, Alabama. That same year, Schreiber installed its Model GR aeration technology at College Hill Poultry in Pennsylvania. In 1980, Schreiber developed the single reactor-basin approach for advanced biological wastewater treatment – the cornerstone to Counter Current Aeration and later the development of Schreiber Flex Controls™ and the Continuously Sequencing Reactor. Schreiber Corporation was sold to U.S. investors in 1986, and has operated independently since.

Schreiber LLC remains an industry leader through continual technological innovation. In 1995 the Fuzzy Filter, a compressible media filter system, was first installed in Columbus, Georgia. The company continues to strive for more advanced wastewater treatment systems: Schreiber’s FlexControls monitoring and control systems, patented in 2008, give facilities state-of-the-art tools to maximize efficiency.

Schreiber offers individual wastewater components, complete systems, and a wide range of energy efficient and innovative wastewater treatment options from influent to final discharge. With the highest quality fit and finish, Schreiber’s durable systems help achieve low operating costs while consistently meeting or exceeding our customers’ expectations.

Schreiber has provided unique design (over 25 patents on product lines from screw pumps to tertiary filtration), outstanding fit and finish, on-site expertise and responsive service since 1979.
Schreiber continues 'IMPROVING WATER THROUGH TECHNOLOGY' with technological innovations such as the  Fuzzy Filter™ compressible media system and the Continuously Sequencing Reactor  greatly improving cost effectiveness and energy efficiency in wastewater treatment, which continues to identify Schreiber as a leader in the industry.

In addition to our innovative products, Schreiber also provides consultation services to evaluate, design and construct the water treatment  equipment for use in any water treatment setting.



The Schreiber Clarifiers are versatile and very durable peripheral drive clarifiers. The peripheral drive system utilizes leverage rather than center-drive torque to rotate the scraper and skimming assembly, resulting in a simplified mechanical system. The equipment necessary for the continuous removal of floatables and settled solids is suspended from either a rotating bridge or, for smaller units, a lightweight rotating beam arm. The rotating ...
