Process control

• Direct UF–RO integration was implemented through an advanced control scheme. • RO concentrate stream was utilized for UF backwash. • Pulse backwash significantly improved overall UF backwash effectiveness. • Self-adaptive UF backwash successfully retarded the progression of UF fouling. A novel RO d

This study focuses on measuring the process dynamics for the multistage flash desalination process (MSF) in an industrial unit with a capacity of 4546 m3/d. This is a novel addition to the literature because previous studies are limited to theoretical analysis of process dynamics or controller tunin

This work presents a dynamic simulator for MSF desalination plants. It takes into account the heaters and stages dynamic, hydraulic, standard instrumentation and control systems. This simulator was developed to study the effects of faults that may affect a MSF system. In order to extend the results

A special process control was required to cope with partial production during peak hours in order to take profit of lower electricity tariffs. The process control philosophy was based on separation of the system to independent subsequences with the purpose to achieve fully automatic start-up and nor

At a time of intensive demand for producing fresh water at a reasonable cost, addressing automation, process control and cost optimization of desalination plants have become increasingly evident. Large-scale direct seawater reverse osmosis (RO) plants must perform at high standards due to the increa

Process control is an essential part of the desalination industry that requires for operation at the optimum operating conditions an increase in the lifetime of the plant and reduction of the unit product cost. A review is presented for the commonly used and newly developed control and instrumentati
