Retrievable Grid Wastewater Treatment Systems

Retrievable grid wastewater treatment systems incorporate a groundbreaking design that allows for easy inspection and maintenance of the basin and wastewater equipment. The system features a lifting mechanism that enables one section of the grid to be lifted while the other continues to operate. The sections can be engineered to be lifted by a crane or winch.

Depending on the configuration, the diffusers can either be mounted on the stainless steel frames or mounted to the basin floor. The retrievable grid system can also be fitted with tube or disc diffusers. These grids form part of a diffused aeration system, making them essential for the secondary stage of wastewater treatment.

SSI Aeration is a global leader in designing and manufacturing revolutionary wastewater systems, and this solution is no exception. These retrievable grid wastewater treatment systems offer the following benefits:

• Easy maintenance: One of the primary benefits of a retrievable grid system is its ability to provide easy access to equipment for maintenance needs. In addition, inspecting and servicing the basin without having to dewater the tank is possible.
• Better oxygen transfer: Retrievable grid systems feature diffusers that pump air into the tank from the bottom to the surface, resulting in increased oxygen transfer efficiency and potential energy savings.
• Continuous operation: Whether you’re conducting routine inspections or replacing a diffuser, SSI Aeration’s retrievable aeration system is designed to operate continuously throughout a service without causing any disruptions to the treatment process. For this reason, these systems are ideal for plants with only one tank.

Diffusers are an integral part of any retrievable grid system since they supply the oxygen that breaks down pollutants in the wastewater during the treatment process. SSI Aeration designs high-performing diffusers for aeration systems, including:

Tube Diffusers

SSI’s tube diffusers have neutral buoyancy, which enables them to remain sturdy when a retrievable grid is being lifted for maintenance. The design uses less stainless steel, making these diffusers more cost-effective and quicker to engineer.

Disc Diffusers

Disc diffusers are highly durable with minimal maintenance requirements. Due to the longevity they offer, these diffusers work well for a wastewater system where replacements or repairs would be costly or time-consuming.

SSI Aeration provides a wide range of retrievable grid wastewater treatment system services. The design department can handle various processes, including 2D and 3D drawings, specifications and CAD drawings. The SSI team also conducts calculations, process simulations and hydraulic studies to ensure a highly efficient and durable system design.

The installation crew can perform wastewater aeration system installation using industry-standard methods. The retrievable grid system can also be pre-assembled at SSI Aeration’s factory, enabling contractors or operators to complete their own installation easily.
