Soil, water and air testing facility

Published March 11, 2025

Verhoeve Netherlands has a well-equipped test facility. Here we perform tests on soil, water and air for application in soil remediation, but also for process water treatment in sectors such as "food" and floriculture. We focus on the removal of contamination, pathogens, odor and color. This makes the test facility an important pillar of the activity of Verhoeve and other companies within the group of companies to which Verhoeve belongs.

We conduct the tests for customers who require insight into removal techniques in their specific application. The tests range from simple beaker tests to full-scale pilots from which the design parameters for the full-scale application are derived. Pilots are carried out at our test facility in Dordrecht, but if desired also at the customer's site.

Based on the tests carried out in 2024 and their translation, we were able to provide a full scale solution for, among others, 2 deodorization plants at a compound feed plants, 2 water treatment plants for the removal of heavy metals and PFAS respectively, and a specific disinfection issue for an ornamental horticulture food solution. The plants for this application will be installed by Verhoeve in 2025.

Featured: Decolorization

Liquids do not always have the desired color for their application. Sometimes there is too little transparency for UV treatment, sometimes the color is unattractive for further application in the food chain. Ozone can be a solution for this. After all, ozone has excellent decolorizing properties.

With this fact in mind, Verhoeve's R&D department set to work. Over the past few months, a large number of tests on various liquids have been carried out on customer demand. In these tests, the decolorizing effect was confirmed. The photo below shows the results of a test with decolorization by ozone in the food sector. During the treatment, the color decreased from dark blue-green to milk-white.

Our customer is very enthusiastic about this result and in April we will conduct a pilot test for this on a larger scale. If you are also looking for a good method for liquid decolorization, or another challenge in the treatment of process water, please contact Verhoeve's R&D department.
