Food & Beverages

KWI’s catalogue of solid-liquid separation solutions are adaptable to the fluctuating conditions in the food and beverages industry. These wastewaters are known to be highly loaded with organic content, suspended solids and have a significant presence of fat. The solution portfolio proposed by KWI as full turnkey solutions or as standalone units includes physical chemical treatments such as KWI DAF and lamella clarifiers, filtration technologies such as traditional sand filters or ceramic membranes, biological treatments including SBR, MBCR and sludge management solutions for biomass.

KWI and its long-lasting involvement has developed complete solutions that include conception and supply of complete process treatment chains that guarantee the highest discharge standard at the lowest capital cost. This strong involvement in the water sector has materialized with hundreds of references all over the world tested and trialed in various food and beverage production sectors.

A new treatment unit in the food and beverage sector often face the challenge of limited space. The size of the production center is extremely variable from a small-scale local producer to a centralized global manufacturer. All these parameters together complicate the conception of a full treatment chain.

Physical Chemical Treatments

KWI manufactures DAF and clarifiers in stainless steel that guarantee an unbeatable lasting solution against wastewater.


Historically KWI Dissolved Air Flotation units have been widely used in this sector mainly for their compactness, their efficiency toward oil and grease content and their performance in suspended solids removal. We offer a diverse range of products and are adaptable to any constraints.

Separation Technologies

KWI offers high quality separation technologies including traditional sand filtration and ceramic UF membranes.

Sand Filter

KWI is experienced in the design and manufacturing of medium- and large-scale horizontal dual media filters such as pressurised filters, V-type filters and variable pore filters to remove total suspended solids and silt before the reverse osmosis.

Biological Treatments

Biological treatments reduce the organic and nutrient content of the water with proven processes such as BAF, denitrification filters, and MBR equipped with ceramic membranes.


BAF combines biological oxidation and filtration together in one structure, eliminating the need for a secondary sedimentation.

Denitrification Filters

Under anaerobic conditions, denitrification filters are widely used for TN removal as either secondary or tertiary treatment for plants to reach rising standards. 

Deep Bed Denitrification Filter

V-type Denitrification Filter

Ceramic MBR

Ceramic MBR can treat nitrogen, phosphate with higher processing efficiency while producing less sludge.
