Water treatment methodology have come a long way in meeting the growing demand for clean and safe drinking water. Two prominent methods, distilled water and reverse osmosis (RO), have played significant roles in this journey. This article explores the history of these treatment technologies and highlights how the industry has progressed to offer quality point-of-use systems that can address various types of water.
Distillation, the process of heating water to create steam and then condensing it back into liquid form, has been used for centuries to purify water. The ancient Greeks and Romans used distillation to obtain pure water for medicinal and other purposes. However, large-scale distillation for public water supply became popular in the 19th century.
The process involves boiling water, collecting the steam, and then condensing it to produce distilled water. This method effectively removes impurities, including minerals, bacteria, and viruses. Distilled water gained popularity due to its purity, but its energy-intensive nature and the removal of beneficial minerals have raised concerns over time.
Reverse osmosis, on the other hand, is a more recent development in water treatment technology. It emerged in the 1960s as a practical method for desalinating seawater, allowing it to become a viable source of drinking water. Reverse osmosis uses a semi-permeable membrane that allows water molecules to pass through while blocking impurities.
Initially, reverse osmosis systems were large and expensive, primarily used for industrial purposes. However, advancements in membrane technology and manufacturing processes made it more affordable and accessible for residential and commercial use. With that said it is important to understand that all reverse osmosis systems are not equal. Third party testing and time in use are the parameters that Water Specialists use to determine which equipment’s they use in their designs. Today, RO systems are commonly employed to remove various contaminants, including dissolved solids, heavy metals, and chemicals.
As the water treatment industry has evolved, the focus has shifted towards providing tailored solutions to address specific water chemistry and contamination removal requirements. Water specialists now play a crucial role in evaluating a client's water source and recommending the most suitable treatment system.
RO systems have become a popular choice due to their effectiveness in removing a wide range of contaminants. Water specialists analyze the client's water chemistry and determine the optimal configuration and membrane type for the RO system. This customized approach ensures maximum efficiency and performance, taking into account factors such as water hardness, pH levels, and specific contaminants present.
The history of water treatment technologies has witnessed the rise of distilled water and reverse osmosis as prominent methods for producing clean and safe drinking water. While distilled water has a long-standing tradition, reverse osmosis has emerged as a modern solution, offering efficient and cost-effective treatment. The industry has progressed to provide quality point-of-use systems, with water specialists playing a vital role in fitting and installing RO systems based on individual water chemistry and contamination removal requirements. With ongoing advancements, the future holds even more promising technologies to ensure access to high-quality water for all.
