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.


Bar Screen

The Schreiber Bar Screen utilizes an endless chain running on UHMW polymeric guides in a geometric configuration for precise travel of the rake arm. It performs a complete job of removing screenings from the wastewater and then placing the screenings into a container for disposal. The rake engages the bars of the screen at the bottom of the channel and from the down-stream side to prevent the potential for jamming of the rake. Automatic operation of ...

Aerobic Digester

Schreiber handles sludge treatment with a unique all-in-one digester and thickener configuration. Termed the GRS, it consists of a central circular thickener surrounded by an aerobic digester in the form of a concentric annular ring. One advantage of the GRS digester/thickener configuration is that it optimizes the space required for sludge treatment. It is very structurally efficient and offers the advantages of common wall construction. The ...
