“…Since the specific capital investment ($/m 3 /day) in RO units is around 20% less than that of MSF units and the hybrid system is similar to MSF (Helal et al 2004), no additional investment will be needed for introducing the former. Moreover, based on the pilot scale application, KISR has already made significant advances in working out the technical details of hybridization (El-Sayed et al 1998, leaving only the area of advanced pretreatment to be researched. A minor investment of $1-1.5 million is needed to cover this research area (El-Sayed, personal communication).…”

The water policies of Kuwait are in need of major reforms in order to cope with the ever-increasing demands without burdening the country's economy. As it stands, the simple approach of increasing desalination capacities and groundwater withdrawal to meet the demands is hurting the economy as well as the natural resources, and is bound to lead the country into a serious water crisis. In this context, this paper discusses the potential alternatives to the current water policies of Kuwait.

“…The magnitude of the challenges facing Kuwait in relation to water cannot be overstated. Natural freshwater resources are very limited and are being depleted; freshwater demand is rising; the costs and energy needed for desalination are among the largest items in the government's expenditure [1].…”

Abstract. The operational processes of the Reverse Osmosis (RO) membrane desalination plants require continuous monitoring through the constant attendance of operators to ensure proper productivity and minimize downtime and prevent membrane failure. Therefore, the plant must be equipped with a control system that monitors and controls the operational variables. Monitoring and controlling the affecting parameters are critical to the evaluation of the performance of the desalination plant, which will help the operator find and resolve problems immediately. Therefore, this paper was aimed at developing an RO unit by utilizing a wireless sensor network (WSN) system. Hence, an RO pilot plant with a feed capacity of 1.2 m3/h was utilized, commissioned, and tested in Kuwait to assess and verify the performance of the integrated WSN in RO membrane desalination system. The investigated system allowed the operators to remotely monitor the operational process of the RO system. The operational data were smoothly recorded and monitored. Furthermore, the technical problems were immediately determined, which reduced the time and effort in rectifying the technical problems relevant to the RO performance. The manpower requirements of such treatment system were dramatically reduced by about 50%. Based on a comparison between manual and wireless monitoring operational processes, the availability of the integrated RO unit with a wireless monitoring was increased by 10%

“…Increase of seawater feed temperature by one degree centigrade will increase the water production of SWRO by 3%. Experiments were carried out in which RO seawater feed was withdrawn from the MSF reject stream [7]. It has been reported that a 42-48% gain in RO product water recovery was obtained for seawater feed temperature of 33ºC compared to an isolated RO plant using surface seawater temperature at a temperature of 15ºC.…”
