Seawater Desalination Plant

1. Seawater Desalination Plant Preface

The seawater desalination plant is accommodate to the seawater which average salinity is less than 35000ppm. The produced water is in accordance with your requirement when among this scale of seawater salinity. Quality of produced water meets National Drinking Water Standards (TDS≤600ppm). The main parts (membrane, high pressure pump and high pressure soft pipe) are warranty for a year free under the normal condition in terms of the request of operating-installation manuals. Requested environment conditions: environment temperature 0~45℃, seawater temperature 5~35℃, humidity 20%~95%.

The functions of this device including raw water boosting and pre-treatment system, online monitoring device of reverse osmosis product water salinity, semiautomatic cleaning and fore & back flushing system with compressed air acceleration of sand filter.

3. Process Flow of Seawater Desalination


4. System components & introduction

(1)Feed pump: Providing backwash and rinsing engine for multi medium filter and precision filter.

(2)Multi medium filters: The function of multi medium filter is to guarantee the entire alga, specially the suspended solid, minerals, metals and many other large particulate get rid of the original water .The filter can reduce the pollution index of the original water which can meet the RO system’s long term requirement .

(3)Precision Filter: In order to prevent the material leakage in filter and left suspended solid from entering the membrane system before water enter reverse osmosis equipment through passing activated carbon filter, a security filter should be set ahead of the membrane system.

(4)Reverse osmosis system: RO system is the central desalination unit in this system, almost all soluble salt, colloid, organics and microbe will be cleaned out by applying the RO membrane’s peculiarity.

(5)Rinse system: Ro system after running chronically, It can be polluted by some substances rinse out hardly. Micro-salt and organics scale chronically to make film performance decline, operating pressure go up, so system must be rinse with chemical agent, so that it return to normal.
