Thailand's Environmental Challenges and Water Resources

Thailand struggles with several environmental issues, including air pollution from vehicle emissions, water pollution from organic and factory wastes, deforestation, soil erosion, and wildlife populations threatened by illegal hunting, accordingly.

Water resources in Thailand are extensive, with renewable water resources measuring 409.9 cu km as of 1999. So, the freshwater withdrawal is divided into 2% domestic, 2% industrial, and 95% agricultural. Despite these figures, Thailand faces water shortages, like many other countries, with large urban areas like Bangkok being more susceptible, accordingly.

The Role of Dams in Water Management

Dams play a crucial role in managing water resources in Thailand. The country’s dam capacity is estimated at 85 km3, which accounts for about 43 percent of the annual runoff. So, the dams fall under four categories:

  • Large dams with a hydropower component
  • Large dams without a hydropower component, primarily for irrigation
  • Small dams for irrigation, livestock, and domestic purposes
  • Small dams used for agricultural and domestic purposes

Despite their benefits, the dams have also been associated with several issues such as overdesigning compared to the annual recharge obtainable.

The State of Wastewater Treatment in Thailand

Wastewater treatment in Thailand is not commonplace. Hence, industrial wastewater is often discharged into rivers and canals, causing significant pollution. However, several wastewater treatment projects are being developed, primarily in the Bangkok metropolitan area.

The Emergence of Reverse Osmosis Systems in Thailand

One of the strategies employed to address water treatment in Thailand is the use of Reverse Osmosis (RO) systems. So, an RO system is a device that removes dissolved solids from water using a filtration membrane. Meanwhile, it works by pushing water through the system using a pump, with a permeate pump reducing wastewater from the system.

How does Reverse Osmosis Work?

Reverse Osmosis is a process that purifies water by forcing it through a semi-permeable membrane. It removes particles, organics, bacteria, and salts, thus making it an effective method for treating surface water, accordingly. So, the membranes used in this process are designed to withstand high pressures, and the system’s capacity depends on the total dissolved solids in the feed water.

The Benefits of Reverse Osmosis Systems

Reverse Osmosis systems offer several benefits. First, they are reliable, efficient, and can last for 10 to 15 years with proper care. The systems can remove not only dissolved solids but also bacteria and many other contaminants. Additionally, the use of a permeate pump can reduce the wastewater by 75 to 80%, saving money and improving the environment.

The Role of Permeate Pumps in Reverse Osmosis Systems

Permeate pumps increase the efficiency of reverse osmosis systems. An RO system equipped with a permeate pump can reduce the wastewater produced by up to 80%, prolong the system’s life, and boost the quality of the clean water produced.

Seawater Desalination in Thailand

Seawater desalination is another method employed in water treatment in Thailand. So, this process uses a reverse osmosis membrane to separate dissolved substances from seawater and purify wastewater before it is released into the environment.

The global reverse osmosis membrane market’s expected growth over the forecast period, coupled with the increasing demand for clean drinking water, is anticipated to drive the Thailand market of Reverse Osmosis Systems, accordingly.

Industries and Applications

The RO technology has numerous applications across various sectors, including:
