Water treatment audit
In the AWA water treatment audit, we carefully check the functionality of each water treatment step. It includes as well a check of the filter backwashing. Based on the results, we provide optimization recommendations, and we support you in their implementation. We also propose individual training programs for your team.
Filter Design
Lhoist remains at your side for the design, commissioning and the modernization of your water plant. Our technical department offers studies and modeling to size and optimize your filter according to your raw water quality and your operating conditions. Mixed water calculations and corrosion evaluations complete this service.

Akdolit® offers an extensive range of reagents and solutions for multiple applications associated with the treatment of drinking, swimming pool and process waters. Our expertise lies in neutralisation, deacidification, mineralisation, hardening, filtration and in special applications targeting specific pollutants
Municipal drinking water needs to meet drinking water standards and must be pure as it is crucial to sustaining human life on earth. As an integral part of the water purification process, milk of lime or lime slurry eliminate undesirable components, such as organic matter and metallic trace elements.
Many industries require large quantities of softened water, in particular as cooling water for circuits and boilers, to prevent the formation of scale.
Desalination aims to remove mineral and biological components from seawater or brackish water, to obtain clean water that can be reintroduced into the drinking water cycle. Desalination offers a drought-resilient, weather-independent and local supply of high-quality water.
The treatment of swimming pool water is necessary in order to provide a perfectly safe water at all times. For this purpose, the recirculated water is filtrated and disinfected.
Akdolit® offers a wide range of filter media to efficiently remove impurities and organic compounds. Highly reactive products, e.g. for the selective separation of iron and manganese compounds, guarantee an efficient and reliable treatment.
