Remove arsenic
Nowadays , pollution of groundwater resources by pollutants, particularly heavy metals, has decreased the quality and inability to utilize these resources. Groundwater contamination with arsenic is often regarded to the proximity of water to soil substrates containing arsenic or the entry of industrial wastewater with high levels of arsenic into surface or groundwater. lately, the World Health Organization has identified arsenic as a carcinogen, and for this reason, sensitivities about its removal from drinking water have risen markedly.
In Iran, regarding to the reduction of groundwater resources, the concentration of arsenic has increased, especially in the area of the Zagros Mountains. This problem will be increased every year because lack of precipitation and declining groundwater levels.
Payame Avaran fardanegar Nanotechnology Company has offered an effective solution by using surface adsorption according to the country's requirements to eliminate arsenic from drinking water. This method uses Nano-based adsorbents.
features :
• No need for electricity and chemicals
• One hundred percent efficiency and no wastewater production
• High adsorption capacity of the adsorbent used
• Very low operating costs
• High arsenic removal capacity (99%)
• No need to set the pH
• Can be used in urban and rural treatment systems
• Equipped with intelligent water withdrawal system
PNF provides arsenic-contaminated water treatment systems in different capacities by obtaining the technical knowledge to manufacture Nano-iron adsorbents. So far, more than 100 arsenic removal units in various rural and urban scales have been installed in provinces such as Kerman, Ardabil, West Azerbaijan, Qazvin, etc.
