Iranian Knowledge-Based Company Produces Fresh Water with Solar Power
“Our knowledge-based company has succeeded in designing and building a portable solar water purifier which can float on seawater, salt water, or even collected rainwater and it effectively absorbs sunlight and converts it into heat,” Farzaneh Heshmati, one of the company's researchers from Tarbiat Modarres University, told ANA.
Noting that the device maximizes the rate of water evaporation and condenses and collects the purified water by using a special technology, he said, “The final output of the device is fresh and germ-free water that is completely disinfected and suitable for drinking.”
“This device is completely solar and does not require electrical energy or moving parts like a pump to operate,” Heshmati said.
In a relevant development last year, another knowledge-based company in Iran had also succeeded in manufacturing a portable water purification device that can separate 99.5% of pathogenic agents from water.
“We succeeded in producing a water purification device with the capability to remove pathogenic agents which can be used for surface water purification,”Reyhaneh Zaker Alhosseini, a senior expert in material engineering and material protection of the knowledge-based company, told ANA.
Noting that the new device separates all airborne particles, bacteria, viruses and pathogenic agents from contaminated surface water, she said, “These pathogens are removed from surface water like lakes, rivers, ponds or hot springs with a single purification step by filters mounted on the purification device.”
Zaker Alhosseini said that the water purification device does not need any electricity, adding, “This device weighs approximately 20 kg and can provide drinking water for 2,000 people with a flow rate of 500 liters per hour. The filters used in this device can be re-washed by using 5% of the purified water.”
She underlined that the device is very efficient and economical and produces high quality water, adding, “Also, it can remove and purify all pathogens from water at a rate of 99.5% by using physical methods without adding any chemicals.”
