While working with Aeration Works crews, we have been able to do improvements to the system to make it run more efficiently. The crews are well-trained on the systems and know what it takes to fix any problem that may come up.
Today, we are exceeding our original (effluent improvement) goals, and can reduce total phosphorus… due in large part to the robust system design (by EDI’s Symphony® program).
The project has been a great success, providing EDI technology is not only reliable, but also simple and easy to install.
The crew you sent here was one of the best I have ever had the pleasure to work with.
Mike Korman at EDI was a true professional and always made it clear that his primary concern was not only a quality finished product, but that any concerns or issues were resolved completely to the City's satisfaction.
We purchased the Extended Warranty with annual inspection to make sure the performance stays top-notch. They have lived up to their guarantee on this spectacular design and installation.
The crew from Aeration Works at EDI was really good to work with. From the beginning we could tell that they were willing to go 'above and beyond' normal efforts to make sure the diffusers for our system were installed in the most professional manner.
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...
Optimization of Diffuser Systems
TECHNICAL BULLETIN 153 Optimization of Diffuser Systems Diffused Aeration System Performance Optimization Operation of aeration systems for biological treatment is well documented as requiring the bulk of energy in wastewater treatment plants (WWTP). Figure 1 shows the electricity requirements for the primary operation in an activated sludge facility. Aeration contributes 50-70%% of the energy requirements in th...
Sludge Removal and Diffuser Membrane Replacement WWT Lagoon at Proccessing Plant
In 1999, Environmental Dynamics International (EDI) installed a partial mix, submerged aeration system with EDI’s FlexAir™ MagnumTM Fine Bubble Tube Diffusers at one of the two wastewater treatment lagoons for ‘Chiquita Processed Foods’ Pumpkin processing facility in Princeville, IL. In 2001, EDI installed another aeration system with MagnumTM non-buoyant diffusers in the second lagoon.
AW System Upgrade at Bridgeport CT EDI Keeps Solving Unique Challenges
The City of Bridgeport, CT is another example of EDI’s ability to provide unique solutions to its clients. The city is part of ‘Long Island Sound’ protected water body cooperation effort that sets stringent discharge limits. The operating company running the plant for the city was struggling to meet those discharge limits; due to their 17-year-old ceramic disc diffuser aeration system that was failing ...
