Performing major maintenance at Intersnack Doetinchem

Published Oct. 16, 2024

Verhoeve Nederland BV has been providing treatment of production wastewater since 2022. Purification takes place before it is discharged into the sewer system. An advanced installation separates the fats used in the production process of snacks from the rinse water.

Intersnack Nederland BV produces at its Doetinchem location a large assortment of types of peanut butter, bran nuts, (un)salted fried and roasted nuts for the North and West European market. This includes its own brands such as Chio.

Periodically, major maintenance takes place and the separation plant and tanks are thoroughly cleaned. Also this time it was a nice cooperation with Te Kloeze Riooltechniek and Olthuis Recycling. Intersnack can move forward with production again.

Verhoeve purifies groundwater at site of R4 works in Ghent

Published Oct. 16, 2024

As part of the complete reconstruction of the R4 around Ghent, preparatory work is to be carried out between Ghent-North and Zelzate in the coming years. At several intersections, utility pipes will have to be rerouted, which means that the groundwater will have to be lowered locally by means of drainage.

Along this 30-km stretch, several groundwater contaminants (PFAS, among others) are present, requiring treatment of the pumped water.

Groundwater treatment plants

Commissioned by Besix, Verhoeve is providing the necessary groundwater treatment plants (up to 50 m3/h) for this purpose, consisting of various components such as buffers, sand filters and carbon filters.

To this end, Verhoeve, in close consultation with Besix, provided customization of new buffers (20 units), various control containers of its own design and make) and deployment of various small equipment.

First installation

The first plant was started up in July 2024, the next one has already been mobilized and will be commissioned in early November. After rerouting the utility lines, several WWTPs should also be provided during the effective reconstruction of the R4.

Collaboration

Besix and Verhoeve have the commitment to carry this out completely together so that we will be busy here until 2030 installing and maintaining the necessary installations. Through this great cooperation, a solution can be offered to the PFAS problem around the R4.

Replacement of aeration dishes without process interruption

At RWZI Westerlo, Verhoeve Belgium is replacing aeration bulkheads without disrupting treatment processes. Aeration bulkheads are periodically renewed every 8 to 10 years for optimal efficiency.

For installations with multiple aeration basins, this can be done after alternately emptying one basin at a time in dry weather. When only one basin is present, retractable frames are used so that the dishes can be replaced frame by frame. After replacement, a pattern test is first performed at shallow immersion, as shown in our video.

New frames are currently being installed and tested at WWTP Westerlo.
