Fixed Grid Wastewater Treatment Systems

SSI Aeration, Inc.’s fixed grid aeration systems deliver reliable functionality and support the highest demands in wastewater treatment.

Fixed grid systems are a type of configuration used in a diffused wastewater aeration process. The design features a grid of bolting pipes permanently fixed to the floor of a tank, covering the entire area. This diffused aeration system also includes air blowers and diffusers that are connected to the piping.

Air blowers pump pressurized air through diffusers. Then, the air is released as bubbles and introduced into the tank to break down organic matter and pollutants in the wastewater. The diffusers also play a role in mixing the oxygen with the wastewater to maximize airflow and contact. Diffused aeration systems work from the bottom up, keeping the bacteria suspended in the oxidized water for longer as the aeration rises.

SSI Aeration’s fixed grid systems make the diffused aeration process much more efficient because they use the entire floor. This is also an ideal configuration for diffusers that require minimal to no maintenance.

SSI Aeration manufactures fixed grid wastewater treatment systems with unparalleled engineering, quality components and efficient performance at every stage. Take advantage of the following benefits of these aeration systems:

  • Greater durability: The wastewater treatment specialists at SSI Aeration design and engineer aeration systems using high-quality, sturdy materials with superior fabrication to ensure long-lasting performance.
  • Improved reliability: Once installed, SSI Aeration’s fixed grid systems support the most demanding wastewater treatment needs.
  • Higher efficiency: These systems offer optimum floor coverage for an enhanced mixing process, resulting in more efficient oxygen transfer.

SSI offers robust, energy-efficient diffusers, such as disc diffusers, which are perfect for fixed grid systems. These diffusers have minimal maintenance requirements and an extensive life span, making them the ideal choice for permanently fixed systems where the equipment is hard to reach or cannot be removed for repairs.

SSI Aeration provides a complete solution to fixed grid system wastewater treatment. A high-functioning, long-lasting system starts with a solid design, and SSI Aeration’s design team ensures the fixed grid system meets a company’s expectations for performance and application demands with a full range of services. We take care of various aspects of the design process, from managing the initial planning during consultation to incorporating various customization options.

We also conduct several tests and calculations to ensure the system will work for an application. The SSI engineering professionals will design the fixed grid system to meet a business’s requirements and budget while adhering to regulations.

In addition, SSI Aeration field technicians can help with installation or provide the necessary education to employees to install and maintain the fixed grid system properly. Some systems with a fixed grid configuration are factory-assembled to fit a company’s unique specifications to make installation simple on-site.
