A Comprehensive Guide to Industrial Filtration: Filter Presses, Cartridges, Bags, and Separation Solutions

Industrial filtration is essential for solid-liquid separation across mining, power generation, petrochemical, and food and beverage industries. In this guide, we explore the key filtration technologies that Carsons Group specialises in — helping clients across Southern Africa achieve cleaner processes, reduced waste, and improved efficiency.

Filter Presses

Filter presses are the workhorses of industrial solid-liquid separation. They use pressure to force liquid through filter media, leaving behind a dry, handleable filter cake. Carsons Group supplies and supports plate-and-frame and membrane filter presses suited for mining slurries, chemical effluent, and food-grade applications.

Cartridge Filtration

Pleated depth, membrane, and resin-bonded cartridges deliver precision filtration down to sub-micron levels. They are widely used in pharmaceutical, food and beverage, and industrial water treatment applications where contamination control is critical. Carsons Group provides high-flow and standard cartridges to suit a wide range of housings and flow rates.

Filter Bags

Liquid filter bags provide an economical solution for bulk liquid filtration. Available in felt and mesh media, they capture particles from coarse to fine levels. Carsons Group supplies single and multi-bag filter vessels together with replacement bag media for standard and custom housings.

Centrifuges

Industrial centrifuges use centrifugal force to separate solids from liquids at flow rates up to 180 L/min at 10 micron nominal filtration. They are ideal for recycling process fluids, clarifying oils, and dewatering slurries. Carsons Group offers full spares support and O&M services throughout the equipment lifecycle.

Flotation Columns

Flotation columns are used in mineral processing to separate fine particles based on their surface properties. Air bubbles carry hydrophobic particles to the surface, producing a concentrate for further processing. These are widely used in platinum group metal and base metal concentrators across Southern Africa.

Filter Vessels and Housings

Selecting the correct filter vessel is as important as the media inside it. Carsons Group supplies single and multi-element cartridge vessels, bag filter housings, and custom-fabricated pressure vessels in stainless steel and carbon steel to suit hygienic or industrial service requirements.

Understanding the right filtration technology for your application is critical to achieving consistent product quality, regulatory compliance, and cost-effective operation. Contact the Carsons Group technical team to discuss your specific filtration and separation requirements.
