High Efficiency Diffusers vs. Surface Aerators
Technical Bulletin 162: High Efficiency Diffusers versus Surface Aerators EDI has engineered systems that are well suited for almost any aeration mixing application. With multiple diffuser platforms available, it gives design engineers or users choices for coarse bubble, fine bubble of different types, and several different configurations for the diffuser systems. With this flexibility and multiple configuratio...
Energy Efficient Water Reuse with Maintenance at Southern Oklahoma
The reuse of produced water is becoming pivotal to the continued application of fracturing hydrocarbon recovery techniques. While the sector’s economic and market conditions remain soft, an innovative, cost effective solution is being demonstrated at this facility. Benefits including reduced chemical costs and improved SRB (Sulfur Reducing Bacteria) APB (Acid Producing Bacteria) control are being provided. Impro...
SiteWorks Gives 31-Year Old System New Life
The Metro Wastewater Reclamation District is the major wastewater treatment authority of metropolitan Denver, CO. The Metro District’s Robert W. Hite Treatment Facility (RWHTF) has been operational since 1966, and serves approximately 2 million people. As one of the largest wastewater treatment facilities west of the Mississippi (220 million gallons / 832,790 cubic meters per day capacity) the plant treats and r...
SiteWorks™ Continues to Grow a Happy Customer Base
The Northwest Municipal Wastewater Treatment Plant of the City of Springfield, MO had EDI FlexAir™ MiniPanel™ diffuser system installed and operational for ten years. MiniPanel™ is a unique, fine pore, flexible membrane diffuser that provides superior operational flexibility and oxygen transfer efficiency compared to other membranes or rigid fine pore (ceramic) diffusers. SiteWorks™ – the aeration solutions and ...
General Oxygen Requirements for Wastewater Treatment
TECHNICAL BULLETIN 135 General Oxygen Requirements for Wastewater TreatmentOxygen requirements for municipal wastewater treatment can be predicted closely with the standard laboratory analysis using g the BOD test (special requirements exist for some industrial wastewater). The BOD test is designed to measure Biological Oxygen Demand for the wastewater and provides an excellent basis for design assuming: Wast...
PTFE Coated EPDM Diffuser Membranes
Technical Bulletin 171 PTFE Coated EPDM Diffuser Membranes: Benefits and Limitations Membrane diffuser technology has become the standard for high efficiency transfer of oxygen into wastewater. This difficult service has utilized many materials for membrane construction with premium low oil EPDM having emerged as one of the most reliable materials throughout the industry. Even premium EPDM can occasionally exper...
Field Performance of Fine and Ultra Fine Bubble Diffusers
History – Coarse, Medium, Fine Bubble Diffusers Diffuser efficiencies are generally measured in clean water to allow basis of comparison of similar products and prediction of actual performance in a wastewater treatment plant application. Before standard testing procedures were implemented, SOTE data were managed by the various suppliers of aeration equipment with optimistic results from conducting their own cle...

Energy Smart Designs
TECHNICAL BULLETIN 158 | Energy Smart Designs It is common knowledge in wastewater treatment plants that the energy consumption of the plant is highly concentrated in the aerobic treatment process. Most plants would find that the aeration system consumes as much as 50% - 70% of the energy of the entire plant! This is an area which gives great opportunities for design optimization and opportunities for major gain...
Floating Lateral Successful Operations
EDI Advanced Technology lagoon aeration systems offer robust solution for severe weather operations. EDI personnel are continuously asked about operation of our floating lateral systems in cold weather conditions, and in some cases very hot or sunny weather conditions. EDI offers a wide range of Lagoon Solutions and we are often asked can your floating lateral systems be successful in northern climates? The pho...
