Iranian Specialists Design Advanced Alkaline Filter for Water Purification
“The designed composite acts as an alkaline filter and adjusts the pH of water to the range of 8 to 9 by adding beneficial mineral ions like calcium, magnesium, and potassium,” said Mehdi Moeenian, a faculty member and deputy research director of the Research Center.
“This process not only improves the taste and smell of water, but also makes it more suitable for daily consumption by neutralizing the acidic properties of the water,” he underlined.
Moeenian explained that drinking water with an alkaline pH can help improve the functioning of the digestive system, increase nutrient absorption, strengthen the immune system, and reduce oxidative stress, adding that alkaline water may also be effective in preventing diseases like gastroesophageal reflux and reducing the risk of chronic diseases.
“Given the growing concerns about the quality of drinking water and its impact on public health, the development of this composite could be an effective step towards improving the health of society. The application of this filter in home water purification devices will provide families with access to water of higher quality and beneficial alkaline properties,” he noted.
In a relevant development in 2023, an Iranian female researcher designed a filter to separate oil from water using nanotechnology which can be broadly used in different industries.
Elmira Velayee, who has a PhD in chemical engineering from the Tehran-based Iran University of Science and Technology and a master's degree in chemical engineering from Sahand University in Tabriz has planned to make a water and oil separator system using filters covered with nano coatings that has special wetness.
Regarding her motivation to pursue this technological project, she stated, “In many industries, a very high volume of oily waste is produced, which has become a common pollution in the world and is now considered a serious global concern.”
In addition, oil spill which usually takes place in sea transportation or oil production is an important problem for the marine environment and ecosystem, so separating and purifying water from oil pollution has been a challenging issue in recent years that requires ideas. and new scientific techniques, according to the researcher.
“For this reason, there has been a great demand for the development of effective and inexpensive methods to remove different types of organic pollutants from the water surface and to eliminate oil and oil pollution from industrial and refinery effluents,” Velayee added.
