Seawater desalination equipment

Detail

Seawater desalination device

Product name: Seawater desalination device

Application:

Marine/ land seawater desalination; high salinity brackish water desalination; high-end users for yachts and seaside villas.

Brief introduction:

PLC Control, which can reduce manual manipulation and risk of operatingerrors, to ensure long working life of the plant.

Widely used for marine seawater desalination plant, land-based seawater desalination system, containerized equipment, modularized equipment and brackish water desalination.

Effectively remove organic salt, heavy metal ions, organics, bacteria, germs and other harmful substances. Simple operations, easy maintenance, instance water supply. High pressure pumps are selected from Chinese/ international known brands especially designed for RO systems. High/low protection devices for safe operation. Fully automatic multi-way combination valves for high flux reverse rinse.

The pretreatment includes all the necessary treatment step ahead of the reverse osmosis plant. It is determining for plant life time and to minimize chemical cleaning and membrane replacement. It has a direct impact on the plant performance.

Pretreatment

Before the RO process, seawater entering the desalination plant flows through screens that remove debris, then goes through a traditional treatment process called coagulation and flocculation. In this process, chemicals are added to the seawater to make algae, organic materials and particles clump together so they can be removed more easily in the sand filtration stage.

After sand filtration, the salty water goes through diatomaceous earth filters to remove silt and fine particles. Cartridge filters just before the RO membranes serve as a backstop, removing any particles that may be remaining after the diatomaceous earth filters.

Reverse Osmosis

Next is the RO process. High pressure forces the pretreated water through semi-permeable membranes to separate the freshwater, leaving twice-as-salty seawater and other minerals behind.

The size of each RO membrane pore is about .001 microns, which is about 1/100,000th the diameter of a human hair.

Post-treatment, Blending and Delivery

After the RO process,chemicals are added to stabilize the desalinated seawater.

The reverse osmosis process can also be built with one or two passes, depending on the product water requirements and the seawater salinity and temperature. In most cases, 1 pass is sufficient to reach the EU drinking water standards, specially regarding the boron content (1 mg/L). To reach WHO boron guideline (0.5mg/L), a second pass might be necessary (Boron removal process)

The energy recoverydevice is the key factor that determines the plant electrical costs. It must be chosen carefully based on the local energy costs and environment policies.

Post-treatmentand/or polishing steps are required to condition the water after the reverse osmosis membrane process to make it suitable to your application.

Brine disposal can be an environmental and economical issue in some areas where the fauna and flora are sensitive to local seawater salinity increase. Brine disposal should be studied and engineered case by case.

The art of desalination is to determine and combine available technologies to optimize water production costs and quality.

To adapt our Desalination Plants to your local needs, we offer containerizedmobile units from Intake to Distribution up to a production capacity of 200 m3/h of desalinated water.
