Efficient self-cleaning filtration solutions for land-based aquaculture

The Filtrex ACB filter series is designed to handle varying water quality and protect downstream equipment in intake, process, and recirculated water systems. The filters maintain stable performance even during rapid changes in particle load and water conditions, supporting continuous operation in land-based aquaculture facilities.

Applicable for:

• Seawater, freshwater, and brackish water
• Recirculated process water and RAS applications
• Protection of heat exchangers, UV systems, and additional process equipment.

PG Flow Solutions’ filtration offering for land-based aquaculture is based on the ACB self-cleaning filter series from Filtrex s.r.l, one of the world’s largest manufacturers of automatic self-cleaning filtration systems.

With decades of experience from demanding offshore, marine, and seawater-based industrial applications, Filtrex delivers proven filtration technology designed for continuous operation, corrosion resistance, and stable performance.

The ACB self-cleaning filter is a fully automatic, pressure-driven filtration system designed for continuous operation.

Raw water enters the filter housing and flows through the filter element, where suspended solids and particles are retained on the filter surface. Clean, filtered water exits the filter and is supplied to downstream processes.

As particles accumulate, the differential pressure across the filter increases. When a preset threshold is reached, an automatic backwashing cycle is initiated. Backwashing is performed sector by sector, allowing filtration and cleaning to take place simultaneously without process interruption.

The backwashing process uses filtered water and requires no external water supply, ensuring stable filtration performance with low water consumption.

The ACB filter is built around a robust, pressure-rated filter housing designed for long service life in demanding aquaculture applications. All wetted parts are manufactured from corrosion-resistant materials, selected to withstand demanding aquaculture water conditions.

Key features include:

• Filtration: Continuous
• Cleaning cycle: By differential pressure and/or timer
• Cleaning system: Backwashing by reverse flow, sector by sector
• Compact design cast in bronze-aluminium alloy ASTM B148 C95800
• Type of filtering element: Armored pleated element
• Filtering element material: Stainless steel AISI 316L
• Power supply: Electric or pneumatic

The ACB series is available in a wide range of sizes to suit application requirements based on flow, filtration degree, and capacity.
