✦ Synopsis

Proper pretreatment to eliminate or minimize the fouling potential of feed water is one of the main factors in the successful long-term operation of reverse osmosis water desalination systems, regardless of the type of membrane used.

At the Doha Reverse Osmosis Plant (DROP) in Kuwait, flocculation and dual media filtration is used to treat surface seawater feed. The pretreatment system is designed to provide the three different membrane configuration systems with water of suitable quality and required quantity. The quality is monitored by measuring the silt density index (SDI), turbidity, pH, temperature, and chlorine content.

This paper describes the pretreatment involved, problems encountered, and the feed water quality after treatment during the two years of operation.
