For fishing lovers, you may want to know what is Brackish water, where is brackish water found, is this water source potable, or what fish can live in brackish water? Don’t worry, I will answer all the questions in the post.
Brackish water is water that is saltier than fresh water, but not as salty as seawater. It may result from the mixing of fresh and salt water, as in estuaries, but some human activities, particularly certain civil engineering projects like dikes and the flooding of coastal marshland, can also produce brackish water.
Without proper management, brackish water harms the environment because most terrestrial plant species cannot grow in it.

Where is Brackish Water Found?
The most typical places to find brackish water sources are at water transitions where freshwater and seawater mix. Estuaries are a term used to describe these bodies of water. Man can create brackish water sources, and does so frequently. The construction of dikes and the purposeful flooding of marshlands to create bodies of brackish water for freshwater prawn farming are examples of construction projects that can and frequently do result in large pools and small streams.
Is This Water Source Potable?
Advanced water treatment technologies are needed for the purifying and desalinating to make these water sources safe for human
consumption. Some of the current technologies that are used in the water purification process include: Reverse Osmosis (RO), Ultrafiltration, and other filtration technologies (membrane water filtration). Desalination is being financed by a growing number of international communities to address the problem of water scarcity.
How Do You Treat Brackish Water?
Through desalination, brackish water is treated. Desalination is a procedure that turns saline water into fresh, drinkable water by removing the dissolved mineral salts from the water. The two main desalination methods for treating brackish water are reverse osmosis and distillation. Reverse osmosis and distillation can also be used to desalinate seawater, but because it contains more salt than brackish water does, the process is less effective.
The most popular desalination technology in the world is reverse osmosis. Saline water is pressured through a semipermeable membrane by a reverse osmosis system. The membrane transforms brackish water into fresh water by allowing water to pass through its tiny pores while blocking the passage of dissolved salts and other contaminants. Israel is home to one of the biggest reverse osmosis desalination facilities, with a daily capacity of about 165 million gallons of fresh water.
When desalinating water, distillation is used to simulate atmospheric evaporation. Warming brackish water causes it to turn into steam. Since salts and minerals cannot evaporate as quickly as water, when water condenses and returns to its liquid state, it is changed into fresh water.
Solar distillation and multistage flash distillation are the two main distillation techniques used to desalinate brackish water. Solar distillation is used in small-scale operations and in rural areas, whereas multistage flash distillation is used in large-scale operations.
Multistage Flash Distillation
In multistage flash distillation, brackish water is passed through a number of chambers where it is heated and compressed under intense pressure. The pressure is decreased in each subsequent chamber, which causes the water to quickly boil. Each chamber’s produced vapor is then condensed, becoming fresh water, which is then collected. One of the biggest multistage flash distillation systems is found in Saudi Arabia, which generates about 200 million gallons of fresh water daily.
In solar distillation, a transparent glass or plastic dome is placed over a pool of brackish water. Water evaporates as a result of sunlight passing through the covering, condensing it on the surface. Fresh water condenses on the cover and then drips into a collection trough.
What Are Some Common Uses?
These water sources are frequently used in today’s oil and gas, mining, and other industrial sectors to provide cooling water for thermoelectric power plants. After being purified, it can be used for livestock and human drinking water as well as irrigation for farming.
Can You Drink Brackish Water?
Because brackish water is salty, you cannot drink it. Your kidneys will overproduce urine if you drink salty water in order to remove the extra salt from your body, which will cause you to become dehydrated. But brackish water can be made safe to drink by desalinating and treating it.
How to Make Brackish Water for An Aquarium?
If you enjoy keeping aquariums, you might want to try constructing a brackish water fish tank. The spotted green pufferfish is one interesting fish species that does well in brackish water.
To set up a brackish water aquarium, you will need the following:
- An aquarium
- A bucket
- A high-quality marine salt mix or aquarium salt
- a hydrometer to gauge the water’s salinity.
- a heater for an aquarium, as brackish water fish prefer warmer temperatures.
- Fresh water should be added to a bucket, leaving a small amount of room at the top for the salt that will be added later. Once the water is warm enough, use an aquarium heater. 77 degrees In addition to being the temperature that most commercial hydrometers are calibrated to, Fahrenheit is a good target temperature because brackish water fish can tolerate it.
- To the volume of water in your bucket, gradually add the right amount of salt. Generally speaking, each liter of water requires ten grams of marine salt. When all the salt has dissolved, stir the water and salt together and let the mixture sit for about 20 minutes.
- Utilize a hydrometer to quantify the liquid. The specific gravity (SG) of the water is used by a hydrometer to measure salinity. An aquarium’s brackish water should be between 1.002 and 1.022 SG and 77 degrees Fahrenheit in temperature.
- When the water is prepared, slowly add it to your aquarium while monitoring the specific gravity frequently with your hydrometer to ensure that you maintain the right conditions for your brackish water fish.

What Fish Can Live in Brackish Water?
The ten notable fish species that can survive in an aquarium filled with brackish water are listed below.
- Spotted Green Pufferfish
- Figure 8 Pufferfish
- Betta mahachaiensis (wild betta fish)
- Dragon Goby
- Molly Fish
- Reed Fish
- Green Scat
- Archer Fish
- Columbian Shark
Brackish water is water with a level of salinity between freshwater and seawater. Brackish water occurs naturally in many locations throughout the world and serves as an important habitat for a variety of rare animal species. Although it is harmful to organisms that have not adapted to it, it can still harm the environment. This becomes a problem when such water is purposefully cultivated, as is done in some areas to raise desirable food fish. Furthermore, it tastes bad and could be unhealthy.
