Mesaieed Industrial City – TSE system for Qatar Petroleum


Industrial Cities in KSA • Number of cities increasing • Modon overseas 30 existing and developing cities • Cities located near natural resources – locations can be very remote • More than 3,00 factories in existing cities Courtesy of Fujitsu and MODON


Water Challenges in KSA

Over 80% of water is withdrawn from non-

renewable groundwater aquifers, estimated to contain only a 15-25 year supply of water


Water Challenges in KSA • Only 65% of wastewater generate in the Arabian Peninsula is treated • KSA target - by 2025, cities over 5,000 people should be reclaiming nearly 100 percent of their water • Water currently is mainly reused for irrigation

Challenges for Industrial Cities • high water demand for industrial processes • secure supply required • remote locations not connected to supply and distribution systems


Water Supply for Industrial Cities Options: - Piped desalinated water - Groundwater source - Supply by tankers

Challenges: - Cost - Lack of infrastructure - Security of supply - essential


Water Supply for Industrial Cities Desalination options: - Reverse Osmosis - Thermal Desalination Costs/challenges: - Oil/gas use – water costs linked to commodity price - Transportation – infrastructure and costs - Feed water quality in Arabian Gulf


Wastewater Treatment for Industrial Cities Challenges: - Cost - Lack of infrastructure - Final effluent and pollution of receiving waters (desalination concern)


Efficient Waste Solutions


Water Reuse Systems


Process Optimisation Options studies for industrial processes to improve potential for water reuse Close collaboration with operator to identify process change possibilities


Economic and Environmental Factors

Economic and Environmental Observations Typically for inland cities, the provision of desalinated water is more energy-intensive than the secondary or tertiary treatment of local wastewater

Economic and Environmental Observations Thermal desalination, using fossil fuels, without cogeneration is never as economically competitive as Reverse Osmosis

Economic and Environmental Observations It is estimated that 29% of total industrial water withdrawls could be saved through water reuse, recycling and conservation methods

Economic and Environmental Observations It is estimated that 26% of urban water needs could be met by treated waste water
