What Are The 7 Steps Involved In Effective Salt Water Desalination?

In the process of desalination, salt water is converted into fresh water that’s fit for human use. Given the current world scenario where we’re struggling with natural freshwater sources, Desalacion eficiente de agua de mar is the future. For a future where seawater could be used to replace the use of water from limited freshwater sources, desalination plants need to be set up. 

Currently, most of the commercial requirements are met through the desalination of seawater. Further, this helps in saving the limited natural fresh water for drinking purposes. Now let’s dive right into the topic and find out how the sea water is made fit through desalination for commercial or human use in general. 

1.       Intake system 

Firstly, the seawater has to be collected to treat it further. A saltwater intake system is used to suck in water and put it into the saltwater reverse osmosis plant. Different desalination plants use different methods to get the job done, considering the geology condition, natural disasters, intake area, and meteorological data. 

2.       Pre-treatment

Pre-treatment is necessary to eliminate the risk of bacteria, solids, oil, clays, sand, and other organic matters infused in water damaging the RO membrane. The raw seawater is put through a stringent pre-treatment process to get it ready for the next step. In this process, filters consisting of activated carbon and multiple media are used to purify the water for desalacion eficiente de agua de mar. It effectively gets rid of residual chlorine, suspended solids, and microorganism, colloid particles, and other substances. 

3.       The RO System 

The final show where all the organic particles are removed and the conversion to freshwater happens is in the RO system. Through the semi-permeable membrane, salt and water solution are separated under a certain degree of osmotic pressure. By this time, the water would become 98% TDS-free and is purified. 

4.       Energy harvesting system

This mechanism aims to bring down the energy cost and ingestion by reusing and recycling the RO-generated pressure energy. The essential component for power conservation is the ERD or energy recovery device. Reportedly, it can bring down the energy expenditure of any desalination plant by as high as 60 per cent.

5.       Chemical dosing equipment

The Chemical dosing process remains the most important thing in the entire desalination procedure for desalacion eficiente de agua de mar. When compared to other dosing devices for bactericide and coagulant in the pre-treatment process, chemical dosing is equally important. Other important dosing systems include reductant and antiscalant dosing mechanisms in first level RO and pH regulation prior to the second RO system. 

Every dosing equipment comes fitted with dosing pipes, a dosing pump and a chemical tank. All such equipment is installed at the centre for easy supervision, cleaning, operation, and maintenance. 

6.       CIP cleaning mechanism

Since the pre-treatment procedure aims to get rid of as many contaminants as possible, the membrane’s surface becomes full of pollutants at some point in time. This further adversely affects the membrane performance by making the pressure fluctuate between the outlet and inlet. Hence, it’s strongly recommended to ensure chemical cleaning and disinfecting of the RO membrane at regular intervals. You can use a specialized cleaning device that comes with a tank, pump, and filter. 

7.       PLC Controlling Mechanism

Performance testing software is available to carry out a creative industrial PLC control. It ensures online regulation for system performance and process meters to identify and notify the users of any potential maintenance requests or system faults. To ensure desalacion eficiente de agua de mar and smooth working of your desalination plant, installation of a PLC controlling mechanism is very important. 


With the depletion of quality freshwater sources, commercial facilities are moving towards desalination to fulfil their regular water requirements. We hope you’ve got a clear idea of all the steps carried out inside a desalination plant to deliver clean and fresh water for human use. All the technologies available today come with unique characteristics and limitations. Even though the current model delivers promising results, experts in the industry from all across the world are brainstorming every day to bring improvisations to the technology. With each passing day, it’s becoming more energy efficient.
