Water Desalination is the process of desalinating seawater into freshwater. The desalination process is typically done by introducing seawater into the plant by an offshore pipeline. Multiple water properties need to be measured and analyzed to assure the feed seawater is suitable for desalination processing to prevent fouling, scaling, and corrosion of equipment and reduce operational costs. These parameters include seawater temperature, total dissolved oxygen, turbidity, conductivity, total dissolved solids, and pH. This paper will discuss developing and integrating a low-cost, highly scalable sensor subsystem measuring water conductivity in the Arabian Gulf.
Water is the new oil of the 21st century due to increased consumption and demand. High-quality water with free of contamination is vital for human beings and many industries such as oil and gas, petrochemicals, pharmaceuticals, and food. To meet the massive amount of freshwater production, United Arab Emirates (UAE) relies on the energy-intensive Multi-Stage Flash (MSF) and Multi-Effect Distillation (MED) technologies to provide fresh water for various applications. These energy-intensive processes consume a significant share of UAE oil and gas. In general, thermal desalination is an energy-intensive process. UAE is shifting to use Reverse Osmosis (RO) desalination for the freshwater production. To reduce the energy consumptionand the pretreatment stages onsite monitoring of the seawater intake has to be intensively recorded. This study discusses a design of a seawater test station, which has a sensor network to measure the quality parameters of seawater, including the water’s pH.
