Product Description

ABOUT US
 

QDEVU is a national leader in the design and manufacture of wastewater treatment plant equipment.  This includes innovative, robust, and energy-efficient engineered membrane diffusers. These include fine bubble diffusers, coarse bubble diffusers, and aeration systems.  

OUR SCOPE OF WORK

EVU participates in all phases of a wastewater project, from diffused aeration and MBBR system design, manufacture, supply, installation to startup.

 

 

Diffused Aeration - Fine and Coarse Bubble Systems

Our Diffused Aeration Systems are Simply the Best

With over a decade of experience, EVU' aeration systems are recognized for consistently meeting or exceeding customer expectations. For your next project, allow us to evaluate your application and recommend the best fine or coarse bubble aeration system solution based on the following:

• Application Design Support
• Efficient and Cost Effective System Design
• Proven Performance System Selection
• Unequaled Product Quality
• System Reliability Resulting in Lowest Cost of Ownership

EVU' experience and installed system performance exhibits our commitment to working closely with our customers to design the best aeration / mixing system for every application. The Design Request Questionnaire provides our engineers with critical information to ensure our recommendations meet your performance criteria and result in a successful installation.

Design parameters critical for determining the most efficient system to meet your aeration and mixing objectives include:

• Type of Diffused Aeration System
• Basin / Tank Sizing
• Number of Diffusers and Aeration Grid Configuration
• Airflow and Pressure Requirements

Each aeration system design includes design calculations, performance data, specifications, layout drawings and system support.

An Diffused Aeration System can be designed for installation in concrete (poured in place or pre-cast), steel or fiberglass tanks / basins. Attention to ease of installation, low maintenance and reduced replacement costs are considerations in selecting the right solution to meet or exceed performance expectations.
