Activated carbon for water filtration: how does it work?

With drinkable water decreasing amount given the adverse effects of global warming, more and more organizations are investing in the desalination processes for seawater. The future of planet Earth is in crisis and water war could surely be a thing in the future. In order to avoid such a destructive future, desalination methodologies are being opted to keep up with the water needs. However, the process of Desalacion eficiente de agua de mar or efficient desalination of seawater can be a hectic task.

This requires the help of a proficient team or service provider who has mastered the intricacies involved in Desalacion eficiente de agua de mar. But, before you hire a service provider for your desalination needs, let us take a look at the entire process in depth.

What is the Desalination of Seawater?

Desalination is the process that removes the mineral components present within saline water. In general terms, desalination or Desalacion eficiente de agua de mar is a process that involves the removal of minerals and salts from seawater.

Saltwater filtered through the desalination process is fit for irrigation or human consumption. The normal by-product that comes from the desalination process is known as brine. This by-product is a solution of water and salt with the highest mineral concentration. To describe the context, freshwater has 0.05 percent of mineral or salt content. On the other hand, brackish water’s mineral content can vary between 0.05 and 3 percent. The seawater generally consists of 3 to 5 percent of mineral content. Lastly, brine is a water-mineral solution with the highest concentration going as high as 28 percent from a minimum of 5 percent.

Uses of Desalination

Desalination is an old concept where people used to boil the saltwater & collected the resulting steam with the use of sponges. The basics are still the same with a major change in technology used which makes the process faster and highly efficient.

In essence, Desalacion eficiente de agua de mar is the process that tends to mimic the evaporation and condensation process that is a part of nature. The distillation or desalination plants tend to refine & speed up the process with the application of artificial cooling and heating equipment. Given the fact that desalination requires a chunk of energy, most distillation plants can be seen working alongside the power plants. This is where the desalination can be done with the use of waste heat that helps create a volatile temperature for water. In simple terms, this helps bring down the overall cost involved in the desalination process.

So, where is this desalinated water needed?

Desalinated water is something of a boon in times where global warming is significantly drying up our natural water reservoirs. In years to come, this could be the potential method for obtaining drinking water. Today though, it is still popular with uses in:

• Manufacturing Processes
• Cruise Ships
• Submarines
• War Ships
• Industrial Cleaning Needs
• Packaged Drinking

Given its high energy consumption rate, Desalacioneficiente de agua de mar can be costlier as opposed to freshwater obtained directly from groundwater, water conservation, or water recycling. However, all these alternatives aren’t accessible at all times. Plus, the rapid depletion of the water reserves all over the world has led to scientists and technical geniuses trying to figure out cheaper methodologies for desalination.

At present, approximately 1 percent of the total world’s population depends on the desalinated water in order to meet their daily needs. However, the United Nations believes that 14 percent of the globe’s total population shall be affected by water scarcity issues as we approach the year 2025.

The methodology used for Desalacion eficiente de agua de mar

When it comes to the efficient desalination of seawater, there are multiple methods in place. Each of these methods come with their pros and cons.

• Solar Distillation

This particular process for Desalacion eficiente de agua de mar tends to mimic nature’s water cycle where the primary source of heat is sun and evaporation occurs from the seawater due to this heat. The first kind of solar distillation process uses photovoltaic cells for the conversion of solar energy to its electrical counterpart. On the other hand, the second process uses heat from the sun for desalination that is powered via solar thermal energy.

• Vacuum Distillation

In the case of vacuum distillation, the atmospheric pressure in the area is reduced. This helps lower the overall temperature required for the evaporation of water. Liquid starts boiling at the instance when the overall vapor pressure becomes equal to the place’s ambient pressure. With the gradual increase in temperature, the vapor pressure also increases.
Multi-Stage Flash Distillation:In this method, water from the seawater is evaporated & separated via multiple stages of flash distillation. This is actually a series comprised of flash evaporations. Each of these subsequent processes utilizes the energy which is released from water vapor condensation.

• Multiple-Effect Distillation

MED or Multiple-Effect Distillation works via a line of steps termed as effects. The incoming water from the sea is sprayed on the pipes that are heated up in order to create steam. This particular steam is then used for heating up the next batch of water.

• Vapor-Compression Distillation

The Vapor-Compression Evaporation process involved the use of jet stream or mechanical compressor for compressing the vapors that are present just above the water. This compressed variant of vapor is later used for provisioning the heating needs for Desalacion eficiente de agua de mar. Given the fact that this system requires a high amount of power, it is cost-effective only if the desalination process is conducted at a smaller level.

• Reverse Osmosis

The best process opted for desalination with regards to yearly growth and installed capacity is RO or Reverse Osmosis. The Reverse Osmosis process uses semipermeable membranes & applied pressure for preferential induction of water permeation via the membrane. This helps reject the minerals and salts present in the seawater. The Reverse Osmosis process uses less energy as compared to the thermal desalination process.

Apart from these popular processes, there are several other processes that are being tried and tested in the real world. This includes processes such as Freeze-Thaw, Electrodialysis Membrane, Membrane Distillation, as well as Wave-Powered Desalination.


Even though the process of desalination has been criticized for its high energy consumption, there is a need for desalination in the current world scenario. Things are already in place for the reduction of this intense rate of energy consumption with technical junkies and scientists perfecting things as they go. While this happens, current desalination methodologies are being adopted in factories, manufacturing units, and several other places to help with the freshwater depletion issues. So, if you are a factory owner in need of desalination for your plant, make sure you look for a reliable service provider that has been in the field with proper experience.
