Projects for the desalination of seawater to provide drinking and industrial water are frequently constructed as integrated power generation and sea water desalination plants. In this context it is very important to choose and optimise the most appropriate plant configuration and technology for the desalination process. This applies in particular to privately financed projects in public-private partnership models. That is why YASCE and the ILF Group always designs such facilities individually, to best meet the specific project requirements. This encompasses both processes for sea water desalination as well as raw water treatment and post-treatment and/or conditioning of product water in line with the relevant requirements.
These plants include:
Sea water desalination plants of all sizes, Thermal processes (MSF, MED), Membrane processes (RO, ED, NF), Hybrid systems, Integrated power generation and sea water desalination plants
The plant consists of three (3) systems: pre-treatment system, RO system and post-treatment system. The pre-treatment system comprises a chemical treatment (disinfection and pH adjustment) including in-line coagulation, followed by 4 x 25% flocculation and dissolved air flotation units (only operative during red tide periods), 3 x 50% self-cleaning security filters and 14 x 8.33% UF trains. In normal operation DAF is not expected to be necessary so intake pumping is normally by-passed to self-cleaning filtration and ultrafiltration units directly after in-line coagulation.

The plant is supplied by seawater abstracted through an existing seawater intake. The feed water is a blend of seawater and MSF heat reject. The pre-treatment for RO is performed using dual media filtration during normal operation condition, while dissolved air flotation is used upstream of dual media filters in case of red tide events. The plant is designed to have 100% availability also during red tide events.
