The problem of Soil salinity and Salinization

Soil salinity is a condition in which land is contaminated with salt levels exceeding the allowable threshold, which is caused by seawater directly entering the territory when high tides occur, sea levels rise, or when freshwater sources are depleted. Accordingly, dissolved salts are brought to land by sea water, gradually agglomerate, and accumulate to form a salty soil condition.

This has caused serious difficulties for daily life and community health, while also negatively impacting the local economy. In particular, during the dry season in southern Vietnam, increased salinity also causes people to lack fresh water for daily activities.

 

How to identify salty water sources

To determine the level of salinity in water, we will measure the dissolved concentration of salt, expressed in ppt units. Normally, saline water will have a salinity ranging from 10 - 30 ppt.

This determination is necessary because using saline water sources will carry many health risks, which can lead to problems such as gastrointestinal diseases, reduced immune function, liver failure, and CKD, etc,.

Brackish water sources have a PPT greater than 10 and less than 30

 

Cooperating with Hyorim Vina to treat salty water, providing clean and safe water

Shortage of fresh water is one of the biggest challenges that salinity causes to communities. Because people cannot use salty water for daily needs such as bathing, washing, laundry, etc. because salt water is highly corrosive, causing corrosion on the skin of hands and damage to the drainage system and water containers.

Furthermore, without fresh water sources, farmers cannot irrigate crops, leading to a significant decline in agricultural production. In particular, saline soil negatively affects the growth and development of plants, leading to mass death. Along with that, the freshwater aquaculture industry also suffers heavy losses due to the impact of saltwater intrusion.

Understanding the damage that saline intrusion causes to people's lives and the local economy, Hyorim Vina has provided many solutions to treat saline water in many places across the country, which not only ensures water resources but also protects the local economy but also creates a safe living environment for everyone.

Below is one of the typical saline water treatment projects that Hyorim Vina has implemented in Giong Trom district, Ben Tre province.

 

1. Current situation of saline water in Giong Trom district, Ben Tre province

Giong Trom district, Ben Tre province is one of the places most heavily affected by saltwater intrusion. The daily lives of local people are facing difficulties due to reduced freshwater resources, causing significant damage to their economy and livelihoods.

According to Tuoi Tre newspaper, in 2021, the water price here reached 51,000 VND/M3, a price too high compared to the income of the majority of households in the area.

When water salinity increases and cannot be used, factories have to buy water by barge from elsewhere at a cost 3 to 4 times higher than the price of freshwater sold to people.

2. Solution: Install a salty tap water filtration system

Fully aware of the difficulty in transporting and treating water from other places to sell to people, Hyorim Vina has cooperated with Hoan Sinh water plant to establish a brackish water treatment system with a large capacity, achieving 8000 M3/Day. The goal of the project is to provide high-quality water to meet the daily needs of the community.

Modern water filtration systems are capable of solving almost all risks that exist in water, including dirt, bacteria, heavy metals, chemicals, viruses, etc. That is because the system uses Advanced UF / RO membrane technology stands out with its ability to treat saline water at many different levels.

3. Solution: New Korean technology "Electro-Sorption"

Among a series of current technologies, RO is highly appreciated for its ability to effectively filter and produce quality water products. However, this method requires a lot of regular operation and maintenance costs, even during the rainy season to ensure the system operates smoothly and stably.

To face these challenges, we have come up with another solution, suitable for the specific natural conditions of each locality, which is to use Electro-Sorption - advanced technology from Korea. This device not only has the ability to desalinate by absorbing ions to provide high-quality output water but also saves significant energy.

Understanding the difficulties that people in the South are facing when salinity water increases, Hyorim Vina has proactively cooperated closely with local authorities and businesses to come up with effective, approved, and adjusted solution to suit each specific area to bring clean and safe water to the community.

In the current market, there are many businesses providing domestic water filtration systems, but not all of them guarantee the quality as their advertising messages.

As a technical - trading company, Hyorim Vina has been providing many services such as consulting, specifying, installing, maintaining, supervising and selling in many saline water treatment projects in Southeast Asia and other countries. We are confident that we will bring the most reputable and quality solutions and products on the market, helping you always feel secure about clean water sources for agricultural production and daily living.
