Iranian Scientists Use Two-Stage Filtration System to Produce High-Quality Water
“In cities and areas where there is fresh water, we only need to remove microbial pollution and change the taste and smell of water. Two-stage systems remove microbial load and bad taste and odor from water,” Ali Akbar Babalou, a faculty member of Sahand University of Technology, the chairman of the board of directors and a technologist of the company, told ANA.
Noting that in the first step, the carbon filter easily removes the taste and smell of water, he added, “In the second stage, the ceramic membrane removes microbial contamination.”
Babalou underlined that the certificates that his company has obtained from Iran’s water authority and microbiological laboratories like the University of Tehran show that all these contaminants are removed by ceramic membranes.
“Membranes also have no water loss and can purify all water. After some time, they can be washed and reused. This device preserves all useful water salts like calcium, magnesium and iron, as a result, people drink high-quality water,” he said.
In a relevant development in August, researchers at a knowledge-based company in Iran had also produced solid type of polyaluminium chloride which is yellow powder for drinking or wastewater treatment.
One of the problems that industries create is a large amount of wastewater they produce and they release into the environment. Given the severity of the problem, a knowledge-based company in Iran has prevented the spread of environmental pollution by producing a purifying material called Poly Aluminum Chloride (PAC). This substance has the property of coagulating pollutants.
Polyaluminum chloride is a water purification material, an inorganic polymer coagulant, and a polymer with a relatively large molecular weight and a relatively high charge of inorganic polymer produced by the bridge action of hydroxyl ions and the polymerization of polyvalent anions.
This knowledge-based company in Iran has succeeded in producing powder and the solid type of polyaluminum chloride. Factories in Iran used to employ the liquid type of polyaluminum chloride which was imported into the country from overseas.
But nowadays, this knowledge-based company has produced a solid type of PAC through an exclusive formulation.
The material is capable of removing 80% of wastewater contaminants. Due to its compound, this material has the capablity to remove water and wastewater pollutants, including turbidity and floating materials, organic and oily matter, various colors, dangerous metal ions, as well as BOD and COD up to more than 80%.
