Iranian company develops nanotech filter to eliminate 98% of toxic wastewater odors

Iranian knowledge-based company Kimiagaran Sanat Amirkabir has developed an innovative nanotechnology-based filter capable of eliminating up to 98% of foul odors and toxic gases, particularly hydrogen sulfide (H₂S), from wastewater systems.

This cost-effective solution offers a competitive and locally manufactured alternative to imported technologies.
According to Iran’s Vice Presidency for Science, Technology, and Knowledge-Based Economy, the new nanofilter is designed for use in manholes, septic tanks, wastewater treatment facilities, and industrial complexes such as petrochemical plants and refineries.

In warm seasons, the unpleasant smell of sewage and toxic gas emissions poses serious health risks to residents and workers in affected areas.
Hydrogen sulfide, known for its “rotten egg” smell, is a highly corrosive and toxic gas. Even at low concentrations, it can cause headaches, nausea, eye irritation, and neurological issues, while higher levels may be fatal. The nanofilter features a fire-resistant structure that absorbs pollutants while allowing water to pass, helping manage runoff and prevent blockages.
Benefits include low maintenance, long service life, low power consumption, and competitive pricing.
The filter casing is made from corrosion-resistant stainless steel or polyethylene, depending on environmental needs, making it a robust and scalable solution for Iran’s vast wastewater infrastructure.
