Analysis
Our laboratory can perform the following analyses:
-
Bathing water: outdoor - indoor swimming pools
In bathing water, we do not only distinguish between the types of water, but we also divide the analyses in accordance with the legal requirements for the countries: VLAREM II (Flemish administration for environment) for Belgium and WHVBZ (Law hygiene safety bath and swimming facilities) for the Netherlands, for France AFNOR and DIN for Germany. Furthermore, we provide our customers the ability to choose a number of additional parameters besides the mandatory parameters to make sure that these customers can count on an additional free support and all inn advice in order to insure an optimal quality of bathing water at all times.

Wastewater
Each company must meet the legal environmental obligations through the annual audit of the wastewater. Based on a five-day or three-day time proportional or flow proportional sampling the government calculates the wastewater charge. When you choose for Labo Derva, you choose for a reliable partner for the proper and complete reporting.
For a wastewater control you can opt for a 3-day or a
5-day flow-proportional sampling campaign. Our laboratory is responsible for the daily collection of samples and for the control of the installation.After sampling, an analysis will be conducted on the following parameters:
- BOD, COD en zwevende stoffen
- metalen: arseen, cadmium, chroom, koper, kwik, lood, nikkel, zilver, zink (S031)
- totaal stikstof en totaal fosfaat (S042, S043)
Finally, the sampling campaign is ended with a report compliant withe the legal requirements.
