Iranian Scientists Produce Nano-Based Granules to Remove Unpleasant Odor of Urban Swage
The research and development (R&D) department of the knowledge-based company has conducted numerous researches and experiments regarding the behavioral mechanisms of various gaseous and solid phase pollutants, including metal fume dust and various chemical gases.
These researches have led to the design of filtration systems with higher efficiency and lower energy consumption, which can effectively solve the problem of pollutants for various industries.
Production of nano granules to remove the unpleasant odor from the urban sewage network is one of the achievements of the knowledge-based company.
“This product was made based on the needs of Iran’s water and sewage company and with the necessary research and development, and it was tested in both the urban and industrial sewage sector and the necessary licenses were received for it. After the pilot production, the industrial production of these granules has been carried out and used in several refineries in the country,” said Seyed Mohsen Hosseini Rawandi, the managing director of the company.
Vapor phase or liquid phase, that is the question wastewater utilities ask when faced with finding a solution to noxious odors.
At some point, every wastewater treatment plant or water resource recovery facility has been subject to comments, concerns or questions about wastewater odor. Through the process of collecting and treating the wastewater from sewers and collection systems, nuisance odors are emitted and often become a point of concern for treatment or mitigation.
Wastewater odor is predominantly expressed through the chemical compound of hydrogen sulfide or H2S, a colorless gas. H2S is a natural by-product of septic environments and/or anaerobic digestion processes. Anaerobic digestion is commonly used to treat liquid wastes at wastewater treatment plants as it creates an environment devoid of oxygen.
