Water production and supply starts at the Al Hoceima desalination plant (Morocco) built by Tedagua
Water production and supply to the city of Al Hoceima (Morocco) and neighboring cities by the desalination plant built by Tedagua started on February.
The plant is designed to supply a maximum yield of 17,300 m3/day (200 l/s), but the current demand is only 4,000 m3/day.
The plant obtains sea water from 6 wells located at a nearby beach. The standard treatment for these types of plants involves a raw water tank divided into two 1,000 m3 reservoirs each that drives the water through 8 sand filters by means of 4 pumps. From here, it goes through 8 cartridge filters (carbon) leading up to the reverse osmosis treatment, which consists of two racks of 98 pressure vessels each. In addition, the plant is outfitted with three energy recovery racks (ERIs). The reject stream is led to a 500 m3 brine deposit, and from there it returns to the beach.
Once the flow leaves the reverse osmosis treatment, and after passing through the reagent dosing systems (lime, chlorine and CO2), it arrives at a treated water tank with similar characteristics as those of the raw water tank. From there, three pumps drive it toward a mixer tank where it is combined with the one produced by the ONEE. Which comes from a conventional water treatment plant that is fed by a swamp located a few kilometers from Al Hoceima.
The population and the organization in charge of the exploitation state that they are satisfied with the resulting water quality in regard to its flavor, hardness and pH since it started being mixed with the one produced by the desalination plant.
