SAFE DRINKING WATER

We produce the best certified filtering material for the removal of arsenic from water.

PVRA® Technology is a new generation granular adsorbent material based on iron oxyhydroxide, specifically designed for the treatment of drinking and industrial water.
Designed, patented and entirely produced in Italy, it represents a reliable, high-performance solution for the selective removal of contaminants. Thanks to its granular structure and chemical-physical properties, PVRA® Technology is mainly used inside pressure filters, ensuring operational efficiency, long service life and compliance with the most stringent quality and safety standards.

Removes

Arsenic, Phosphates, Vanadium, Antimony, Selenium, Molybdenum, Uranium, Lead, Chromium.

Max Adsorption

It has the highest filtration capacity among materials of this type available on the market.

High Efficiency Systems

Allows the design of plants that do not require high doses of chemical products.

Simple and Economical

Quick and easy management for systems with zero or near-zero energy consumption.

HOW DOES THE FILTERING MATERIAL WORK?

Contaminated water: spring or wastewater containing a variable combination of pollutants at different concentrations, compromising its quality and safety.
Filtering material: granular ferric hydroxide PVRA^® with the best adsorption capacity among materials of this kind on the market.
Drinking water: treated and safe water for human consumption, obtained through efficient processes ensuring quality and purity, significantly reducing energy consumption and optimizing resources used in treatment.

FIELDS OF APPLICATION

PVRA^® is designed for industrial fixed-bed or fluid-bed filtration systems in highly complex operational contexts. Its versatility makes it ideal for integration into existing plants or new engineering projects.

Industrial and municipal wastewater treatment plants

Water treatment for the food industry

Treatment of spring and thermal waters

REGENERABLE FOR PROLONGED USE

PVRA^® is regenerable, does not produce polluting waste when saturated and is therefore suitable for regeneration.
Regeneration occurs through an innovative Zero Liquid Discharge process that produces no wastewater and allows complete material reuse.
This makes PVRA^® not only effective in removing contaminants but also sustainable environmentally and economically in the long term.

TECHNICAL DATA AND PERFORMANCE

PVRA^® is an advanced material specifically developed for applications requiring extreme performance in precision, efficiency and reliability.
It was created to meet the needs of those operating in complex sectors such as water treatment and high-intensity industrial processes, where performance requirements are combined with safety and operational continuity.

BROAD-SPECTRUM ARSENIC FILTRATION

PVRA ^REG removes arsenic, phosphates, vanadium, antimony, selenium, molybdenum, uranium, lead, chromium. It fully complies with the quality requirements established by the DIN EN 15029:2012 standard for use in drinking water treatment, with particular attention to the strict limits concerning heavy metal content.
