Our Akdolit® Technical Sales Service

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.
