Ingeobras has developed a patented nitrate removal system with the name PUREMUST-SN ®
PUREMUST-SN ® is based on the elimination of nitrates that water contains, by a heterotrophic biological procedure, transforming nitrates into nitrogen gas.
PUREMUST-SN ® can also be used for the elimination of sulfates that water contains by transforming them into gas sulfhydric acid.
It is an economical, easy to use and environmentally friendly solution.
The presence of nitrates constitutes one of the greatest threats to water quality in aquifers, both in Spain and in most developed countries.
Most of the nitrate pollution comes from inorganic fertilisers and animal manure, substances that continue to be incorporated into groundwater.
This has serious consequences for human and environmental health, due to the use of groundwater as a drinking water resource.
In addition, nitrate can persist in groundwater for decades and accumulate at high levels in soil. This is why the EU has updated regulatory frameworks to reduce pollution with increasingly stringent regulations.
Puremust-sn ® is an innovative technology that is already in the commercial phase. It is the most competitive solution on the market from both a technical and economic point of view. It is also environmentally friendly.
With Puremust-Sn the initial investment cost is medium, but the maintenance cost and energy consumption is very low.
It is a proven innovative technology that is already being used by numerous customers around the world and continues to expand.
We have a pilot plant at the disposal of our customers to test its efficiency in a practical and real way.
Reverse osmosis separates nitrates for the initial water supply it is treating, but does not remove them. It creates another, more polluted discharge.
The initial investment cost is high and the maintenance cost and energy consumption is medium.
A problem with this system is that highly polluted water rejects are generated.
This system consists of the contaminated water passing through a material that traps the nitrates, but does not eliminate them. For this reason, a maintenance process is required from time to time to remove the nitrates from the material.
To implement these systems a large investment is needed with a high cost of constant maintenance, being less effective than PUREMUST-SN.
This table provides a visual comparison of the three nitrate removal options available on the market today.
With Filtralite we have developed a technology that removes iron in the most effective and competitive way on the market.
A technology that removes Arsenic in a single step, without the need for maintenance or water conditioning or the use of chemicals.
With the HMR filters we are able to remove heavy metals such as Chrome, Zinc Cadmium, Iron, Manganese, Arsenic, Copper or Nickel.
With Filtralite we have developed a technology that completely removes the Manganese present in the water at the most competitive cost on the market.
A technology that removes Uranium in a single step, without the need for maintenance or water conditioning or the use of chemicals.
Our chemical team is currently working to optimize the results obtained in advanced oxidation processes to gain efficiency and flexibility.
Anaergy is a disruptive technology for water treatment in the agri-food industry, extremely efficient, small and innovative, which also generates energy.
Innovative technology that significantly increases the retention capacity of fluoride contaminants in drinking water.
Innovative technology to recover between 90 and 97% of the total phosphorus present in wastewater for subsequent use as fertilizer.
Innovative technology capable of removing high concentrations of ammonium from drinking water at 99% efficiency.
