Definition of sea water desalination
Sea water desalination is a technology and process to get pure water from sea water.Get fresh water or separate the salt from sea water ,could achieve the purpose of desalination . The method of getting fresh water from sea water including distillation way , freezing way ,reverse osmosis way , hydrate method and solvent extraction ; removing the salt from the sea water including electrodialysis method and ion exchange method .
Marine seawater desalination equipment
We design according to the customer requirement and the special application of the shippings.Its small volume, light weight, save space, easy installation, strong adaptability, can be installed in the narrow crowded ship cabin and deck, the crew compartment, corridor space. The equipment operation is simple and convenient maintenance, as long as there is water, electricity, can provide fresh water immediately after start. The Equipment with a high desalination rate, stable performance,the design is novel and clever, it could avoid the frequent cleaning and no environmental pollution.
The frame made of stainless steel which anti rust and corrosion. Power applicability is wide (220-380-415 - v / 50 hz or 60 hz/three-phase), this desalination system could be used for most of the shippings and its water production quality meet the national drinking water standards.
Reverse osmosis
In the reverse osmosis desalination process, reverse osmosis membrane only allowed water molecules and a small amount of ions could pass through and other ions and impurities will be intercept down, and is concentrated with the reduce of water. This method since no phase change and save energy. Reverse osmosis membrane aperture < 10 x 10-10 m, it can filter out all sorts of bacteria, viruses, and source of heat and other pollutants at the same time and get high quality pure water. The will save cost if the Salt and other impurities low.
Large-scale seawater desalination system
It's widely used in island and encampment in the sea, water shortage city near the sea. This system can remove inorganic salt, heavy metal ions, organic compound bacteria and germ etc, get qualified drinking water from sea water that meeting national drinking water standard
Containerized seawater desalination system
It's designed for island residents' domestic water, or seasonal fresh water supply for tourism, or remote area or emergence fresh water needs. It can be assembled and supplied in short time, little cost and much effective performance. It consists electric control cabinet, chemical dosing system, pre-treatment system and RO membrane module, backwashing system.
Energy Recovery Unit
Energy recovery unit is one of the key device of seawter desalination RO systems and significantly reduce the energy consumption of system operation and the cost of water production . Most of the Energy Recovery Unit of the RO desalination projects which China has put into operation and under construction are imported from abroad, the price is very expensive, and corers 10% to 15% of project total investment . Energy Recovery Unit is an important link in the chain of RO desalination industry, and also one of the key components which need to be conquered for developing RO desalination industry currently . To master domestic energy recovery unit with independent intellectual property rights , gradually breaking down the foreign products monopoly and form a complete domestic industrial chain of RO desalination has become the key to the development of our RO desalination industry.
