Desalination Plant

Desalination Plant
1. Desalination Plant Preface
    This sea water desalting plant is accommodate to the seawater which average salinity is less than 38000ppm. 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℃, Humility 20%~95%.
    The functions of our 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. 
2. The System Requirements of Desalination Plant
requirements of customer
Fresh water standard comply with WHO        
Capacity: 30m3/day      
Salt content: ≤500mg/L
requirements of the device
Raw water: sea water                
Model of Reverse Osmosis: One stage Reverse Osmosis 
Purpose: Marine and offshore 
Power supply: 440V, 60HZ, 3P  
3. Desalination Plant Performance
(1) Sea water 35000-38000 PPM, for desalinating sea water into fresh water 600ppm.
(2) Semi-automatic cleaning and back-flushing system equipped for sand filter.
(3) There is over-pressure protection available for high pressure pump, when pressure is over 6.5Mpa, the system will shut down automatically.
(4) High pressure pump equipped with low-pressure protection device, when pre-treated sea water pressure is less than 0.05Mpa, the system will shut down automatically.
(5) Working parameter (Raw water flow, product flow, brine flow, operation pressure, product water conductivity)
