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...
High Efficiency Diffusers vs Surface Aerators
TECHNICAL BULLETIN 162 | High Efficiency Diffusers versus Surface Aerators EDI (Environmental Dynamics International) 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...
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...
Testing Pipe Support Spacing
Aeration system pipe supports are typically spaced in the industry to provide long-term performance and service of aeration piping systems. In the spacing of these pipe supports, there are several variables that must be considered and evaluated to create a proper design. Clearly, there is a desire to have the pipe supports function properly while using the minimum number in order to control economics for the sys...
Comparison of Flat Panel to MiniPanel Diffuser
EDI recognizes that panel diffusers have high efficiency. With this in mind we have created Mini-Panel devices as alternatives to the flat panel diffuser types to have with the oxygen transfer efficiencies of flat panel configuration while producing actual energy savings because of significant reductions in operating pressure requirements.
Analysis of Panel Diffuser Technologies
Technical Bulletin 174: Analysis of Panel Diffuser Technologies The emphasis on reducing total cost of ownership of biological wastewater treatment plants has driven the technology for aeration and mixing systems to seek ways of higher efficiency and superior performance. Panel diffuser systems have been developed as a result and offer some interesting capabilities in aeration mixing technology. Panels along wit...
