Palmachim Desalination Plant (2004-2011)

Client: Via Maris 

The Palmachim Desalination Plant (DP) is located in the central part of Israel. The facility operates since May 2007 by means of the SWRO technology. The plant was constructed to supply about 30 mil.m3 of fresh water per year in such a way that it can be expanded in the future.

CAMERI has conducted several studies during all the stages of the plant development, starting from its construction. The latest study conducted by CAMERI in 2011 considered a possibility of producing 90 mil.m3 of fresh water per year. The study was performed in order to assess a potential impact of such plant growth on the environment in terms of possible seawater salinity increase around the plant outfall. The study followed the requirements of the Environmental Impact Assessment (EIA) for the Palmachim DP extension.

In the framework of this study near-field modeling as well as far-field modeling has been performed.
In this study the results in near-field obtained using UM3 model served as the boundary conditions for the CAMERI3D/HD-ST model in the far-field.
The study accounted for future development of the Palmachim region, namely the projected construction of the Sorek DP at a distance less than 1 km northward the Palmachim DP.

The study objectives were assessments of excess salinity at the National Reserve offshore margin as well as at the Palmachim and Sorek DPs intakes. The plume’s interaction (if any) from Palmachim and Sorek DPs was analyzed. The study considered two layouts of the Palmachim DP with 90 mil.m3/yr fresh water supply, Layout 1 and Layout 2. The corresponding values of the Sorek DP water production is 150 mil.m3/yr for Layout 1 and 300 mil.m3/yr for Layout 2.

Salinity patterns (isolines) and flow fields (arrows) in the vicinity of the Palmachim and Sorek DPs. calm sea conditions.
Red line = 10% excess salinity; blue line = 5% excess salinity; green line = 1% excess salinity; black isolines between 5% and 1% correspond to 41.4 g/l = 4%, 41.0 g/l = 3% and 40.8 g/l = 2% excess salinity; 40.0 g/l = 0.5% excess salinity.
