Seawater Desalination Plants

Seawater Desalination Plants

WATERTEC offers all the three most popular desalination technologies, which are MSF (Multi-Stage Flash), MED (Multi-Effect Distillation) and RO (Reverse Osmosis), and has proven supply records in all these areas.

Multi-Stage Flash (MSF)

In MSF (Multi-Stage Flash) method, sea water flows through a multi-level heat exchange system, which is then heated with steam from power generating plant until evaporation, and is condensed on outside of pipes through which cold seawater flows. This method is used in large capacity desalination plants.

Multi-Effect Distillation (MED)

MED (Multi-Effect Distillation) is similar to MSF, but only uses of devices called "Effect" instead of "Stage" from MSF. The MED method has benefit of reducing energy consumption if applied with dump heat, and is used for medium-capacity desalination plants.

Reverse Osmosis (RO)

Seawater Desalination Plants

As the name suggests, pressure is applied to seawater in order to separate substances like water and salt and thereby produce fresh water. Its relatively easy operation and low energy consumption make it ideal for all capacities - small, medium and large plants. The Commercial Industrial Seawater Desalination SWRO Systems - designed to convert seawater to drinking water - use high quality reverse osmosis seawater desalination membranes. The product water is used in a variety of areas including municipal, hotels, resorts, military, off-shore platforms, large marine vessels and various industrial applications. Designed for demanding requirements of the tough environments, these systems use our proven technology to give reliable, long-term performance.

Containerized Seawater Desalination System

Containerized Seawater Desalination System

To adapt our Desalination Plants to your needs, we offer containerized mobile units from intake to distribution up to a production capacity of 200 m3/h of desalinated water. The containerized systems are designed for large-scale plants or long-distance delivery, by manufacturing pre-designed module-size plants, fully assembled in standard 20 or 40-ft containers.

The container just needs to be shipped out to where the potable water is needed, and after a brief training session, commissioned workers are ready to produce high-quality potable water within days of delivery. Custom designed individual containerized water treatment solution is available.

Benefits

  • Can adapt to different environments
  • Easy installation
  • No need to leave space or build a new architect to install the system
  • Saves space for customers
  • Suitable for long-distance transport

Seawater Packaged Desalination Systems

It is significant for customers in water-scarce areas to achieve and maintain low operating costs. Our Seawater Reverse Osmosis (SWRO) series packages systems easily meet these needs while optimizing operating costs. These systems cover a range of applications, including boiler feedwater make-up, irrigation water, plant process water, and small community potable water demand. For those applications which have challenging feedwater, these systems offer ultrafiltration and reverse osmosis both to maintain the quantity and quality of water required.

Features

  • Fast lead time on industrial desalination systems
  • FRP membrane housings, high pressure pipe pickled and passivated for corrosion resistance
  • Integrated energy recovery device for energy conservation
  • Remote central control system
  • SWRO media filtration, with clean-in-place, and chemical feed options

Water Desalination Skids

These high-salt-rejection RO desalination systems are best suited for private water supplies, small communities, commercial or light industries with TDS levels up to 500 mg/l. It is a simple stand-alone system with options of pre-treatment with multi-media and carbon filters. Water softeners are recommended with this system for water hardness above 100 mg/l. Larger Systems can be supplied to meet needs and specifications. These systems offer a high level of productivity gains and more water recovery.
