New residual waters treatment for the removal of heavy metals as chrome (VI), cadmium, nickel or lead using natural biosorbents agribusiness. It is a low-cost, sustainable technology that requires an abundance of raw materials and it can be interesting for companies that are working in water treatment.

TECHNOLOGY DESCRIPTION

This technology allows removing heavy metals from residual water through the use of natural adsorbents as cork, coffee or olive stone.

This result is achieved by the adsorption of metals ion on the surface of sorbent materials.

Sorbent materials are derivatives from food industries (such as grape stalk, coffe rests, cork or olive stone) which are really abundant are waste materials, easy to store and redistribute. The removing process of heavy metals have been carried out on synthetic waters that simulate real water. The result of test show that sorvents are effective in continuous systems- as columns- and in discontinuous systems (reactor 5L). Nowadays the proces is being tested in a pilot plant with good results.

BUSINESS OPPORTUNITY

To illustrate it with an example, the chemical industry meant global sales of 2.2 billion Euros in 2006, which represents an increase of 69% respect 1996, with the corresponding generation of waste water contaminated with metals and other compounds. The recovery of heavy metals improves the industrial competitiveness and minimizes the risk of contamination.

The removal of heavy metals from waste water in certain industrial processes is an expensive process for companies, who have to use reagents and non-biodegradable materials.

The innovative aspects of this technology are:
- Low acquisition cost of sorbent materials, due to its abundance and low utilization for other uses.
- It valorizes the waste materials of agribusiness in new uses.
- New way of residual water treatment
- Sustainable technology and respectful with the environment.

License. Looking for industrial partners in order to start bigger pilot tests that works in the water treatment sector.

APPLICATION

The application of the technology is the contamined water (heavy metals) treatment .

Heavy metals are toxic (even with low concentratiosn) and non-biodegradable. This technology is applicable to chemical sector, metallurgic sector and subsectors, as well as many others- electrolytic coating, leather tanning, mining operations, coal-fired power plants, etc.

Advanced materials

Energy efficiency. Renewable energy.

STATE OF MATURITY
Research
Development
Exploitation

In the tests carried out the adsorbents have proved to be affective in continuous systems, such as columns, and in discontinuous systems, 5L reactors. Currently the process is being carried out in pilot plants obtaining good results.
