Ölof Filtration Teknologerna AB has extensive knowledge and experience providing filtration solutions for a wide range of applications in the food and ingredients industry. Food processing is a complex operation with highly critical filtration applications. Our team of experts understands how each filtration step will interact with your product and possibly affect the final characteristics.
Because water is one of the main issues in food processing, our products will ensure that pumped and filtered water is available when and where it is needed to support critical functions in the foodservice industry. We provide a secure source of filter elements and systems to remove color, odors, particles and harmful germs from liquids and gases providing maximum clean fluid quality so foods and ingredients manufacturing will be consistent at each batch.

Primary Processing typically involves applications in which the suspended solids loads are relatively high and particle sizes may be inhomogeneous. The separation target is bulk solids removal.
This step mainly occurs upstream in a process, on aqueous, unconcentrated fluids such as fermenter broth (cell debris removal), gelatin (post-extraction), sweeteners (mud removal), and others. Clarification may also be required after product concentration.
Also some fluids require a small degree of color, flavor or odor correction, which can be achieved by the use of activated carbon (bulk or filter cartridges).
Organic and inorganic materials are sources of contamination and turbidity. There are a wide variety of solutions available to trap DE, carbon, resin, sand and other particles resulting from upstream treatment steps. Excellent trap filtration benefits downstream equipment such as carbon beds, resin beds, UF and RO units by:
- Improving in effectiveness of downstream carbon and resin beds.
- Reducing in the cleaning requirements and change-out frequency of downstream UF and RO membranes.
- Reducing in the need for post-concentration filtration. Fine filtration removes submicron particles, to achieve quality specifications. Polishing filtration ensures consistent product quality prior to packaging.
Bacteria, yeast, and mold can cause sickness, product spoilage, and costly product recalls.
Reducing microorganisms to acceptable levels, or removing them entirely, minimizes these risks. Sterilizing-grade membrane cartridges provide maximum protection. Other choices such as sheet-based products, cartridges with specific titer reduction claims, or crossflow membranes provide bioburden reduction, dependent on process conditions, incoming microbial load, and microorganism type.
