Water purification: What are the most efficient methods?

Ensuring high quality drinking water: the key role of purification

The main objective of drinking water treatment is to ensure that the water is safe for human consumption and meets specific requirements defined by national regulations and competent authorities. In Italy, D.Lgs. 31/2001 is the Italian legislative reference that regulates the drinking water sector by transposing the European Directive 98/83/EC and also defines the criteria and analytical parameters that water must meet to be defined as potable. These standards include microbiological potability, chemical potability, proper taste, odor and appearance, balanced pH, and adequate levels of essential minerals such as calcium, magnesium, potassium and sodium, without exceeding limits. Drinking water treatment plants therefore play a key role in achieving these standards and ensuring high quality drinking water. 

In this article, we will explore different ways to purify water, focusing on state-of-the-art solutions and technologies such as reverse osmosis systems. We will discover the benefits of these approaches to achieving safe, pure, and contaminant-free water.

Reverse osmosis for total purification

Reverse osmosis is a highly efficient method of purifying water: it is a natural process in which a less concentrated solution spontaneously moves to a more concentrated solution through a special membrane. By applying pressure to the concentrated solution that is greater than the osmotic pressure, the natural flow of water can be reversed and dissolved salts in the concentrated solution can be removed. This results in a solution with a low concentration of salts on the other side of the membrane. Reverse osmosis purification systems find application not only for potabilization of water for human consumption, but also for purification of water for industrial plants (such as for cooling) and the agricultural sector.


Customized water treatment plants

Each situation requires a unique solution, which is why it is essential to offer water treatment plants tailored to the specific needs of the customer. Idro's experts assess the quality of the source water and design customized water treatment plants, which may include a combination of different purification technologies, such as filtration, reverse osmosis and other advanced processes. Some examples are:

  • Water softeners, which are used in circuits where it is essential to remove the encrusting salts of calcium and magnesium, thereby reducing the hardness of the water and preventing the formation of scale deposits in pipes and appliances. 
  • UV sterilizers, which are devices for the sterilization of water containing bacteria and chemicals that may be harmful to health or the production cycle.
  • Rapid water filtering systems, filters that work under pressure to speed up the process of water filtration and can be of various types (clarifiers, neutralizers, deferrizers, etc.).
  • The complete system Acquanow, a compact and pre-assembled system for accumulation, lifting, pressurization, filtration and debacterialization, also suitable for cases of low water supply.

In addition, IDRO can provide compact and mobile drinking water plants to produce safe drinking water from conventional and unconventional water sources in areas with limited or contaminated water, such as freshwater, brackish water and seawater sources.
