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 Wastewater Treatment Lagoon at a Pumpkin Processing 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 ...
