Environmental Dynamics Intl. (EDI) is celebrating 40 years of service to the water and wastewater industry, providing engineered solutions for aerated treatment systems. The company helps municipal, private and industrial clients find cost-effective waste treatment solutions, and offers total solutions for many aeration applications, providing engineering design, equipment, installation and ongoing maintenance.
Founded in 1975 by Charles Tharp, EDI has grown from a small company with a few employees and annual sales of $27,000, to a multinational company with more than 105 employees and sales of more than $27 million. The company has offices in the U.S., Singapore, France, Germany, China, India and the U.K., and manufacturing facilities in the U.S., China, U.K., and India.
Throughout its growth, EDI has remained true to Tharp’s guiding principle: Focus on the core competency of aeration and help make life easier for customers by providing reliable, economical, efficient and flexible solutions for their most challenging aeration needs.
EDI’s very first innovation, the REEF System, is a high efficiency, fine bubble lagoon aeration system, introduced in 1977 to address a serious need in the industry. In the 1970s, aeration for lagoon treatment systems consisted of inefficient mechanical aerators or perforated tubing, which was prone to clogging, and cleaning required wading into the lagoon and/or gas cleaning—an unwelcome, labor intensive task.
Other innovations followed for concrete aeration basins and lagoon systems. EDI’s patented Spectrum saddle mount for diffusers provides a connection for attaching tubular diffuser systems to the piping. These saddles expand the industry’s options for tube systems, previously limited to 50 mm (2 in.) diameter maximum and 0.6 meters (2 ft) long, to allow use of a full range of tube diffusers, up to 120 mm (4.7 in.) diameter and 1.8 meters (70.9 in.) long.
EDI’s product line now encompasses all types of aeration diffuser systems to meet any treatment requirement or system configuration.
