Seawater desalination RO reverse osmosis system,

Explanation

Climate change and the rapid development of global industry and agriculture have made the problem of lack of fresh water increasingly serious, and the supply of fresh water is becoming increasingly tense, so some coastal cities are also seriously short of water. The water crisis poses an unprecedented demand for seawater desalination machine for producing fresh drinking water. Membrane desalination equipment is a process in which seawater enters through a semi-permeable spiral membrane under pressure, the excess salt and minerals in the seawater are blocked on the high pressure side and are drained out with concentrated seawater, and the fresh water is coming out from the low pressure side.

Process Flow

Seawater →  Lifting pump →  Flocculant sediment tank  → Raw water booster pump → Quartz sand filter → Activated carbon filter  →  Security filter →  Precision filter  → High pressure pump  → RO system  →  EDI system  →  Production water tank → water distribution pump

YANTAI JIETONG specialized in design, manufacture of various capacity of seawater desalination machines for more than 20years. Professional technical engineers can make design as per customer specific requirement and site actual condition. Desalination is the process of removing salt and other minerals from seawater to make it suitable for human consumption or industrial use. This is done by various methods including reverse osmosis, distillation and electrodialysis. Seawater desalination is becoming an increasingly important source of freshwater in areas where traditional freshwater resources are scarce or polluted. However, this can be an energy-intensive process, and the concentrated brine left after desalination must be handled carefully so as not to damage the environment.
Seawater RO reverse osmosis plant is a commonly method to get fresh water from sea water to solve the water crisis at some areas without fresh water.
