AquaSwiss AG are “The Thermal Desalination Experts !”.

We are a Swiss company with our corporate office and sophisticated engineering centre in the greater Zurich area.

AquaSwiss AG was founded by acquisition of world’s leading thermal desalination technologies and is owned by Netherlands-based Larive Holding BV, parent company of the Larive Group ( We are focused on the markets of Middle East, North Africa and of selected countries in South-East Asia.

Our technology and expertise can utilize steam as low as 0.3 bar to build Multi Effect Distillation (MED) plants from sizes of 2000 to 200,000 m3/day and more.

We can achieve Economy Ratios / GOR (also called product to steam ratio) up to 16 with our MED units, at CAPEX which is significantly lower than in comparable industrial applications. We achieved this result through decades of research, an intelligent selection of construction materials and optimized fluid and thermo-dynamics.

Our Mechanical Vapor Compression (MVC) units are CAPEX and electricity efficient and can be delivered in clustered trains of up to 30,000 m3/day and more. We have advanced pre-treatments such as Nano-Filtration, biological filters and clarifiers coupled with our thermal units to deliver solutions for complex feed-waters such as very high salinities (100,000 ppm), high temperatures and high silica content. Using these solutions we can deliver drinking, agricultural, service or demineralized water from oil & gas produced (formation) water and industrial effluents. We also work with our clients to help them achieve Zero Liquid Discharge. (ZLD).
