Deliverables
Development of biosorption filters for industrial wastewater detoxification and heavy metal recovery
This project aimed at developing a novel technology for detoxification of industrial wastewaters from heavy metals using easy-to-collect adsorbents of biological origin and testing the new technology under real conditions. Industrial sectors expected to benefit from this technology include electroplating and surface finishing operations, tanneries, photographic laboratories, etc. Bench scale and full-scale research led to the construction of prototype filters that were tested under real conditions in electroplating plant facilities.
In bench-scale experiments, over 95% of Cu, Cd, Ni, Zn and Cr were removed from solutions by a single filter. 100% removal is possible by using additional filters. Adsorption capacity was influenced by metal solution pH. Full-scale prototypes were also tested with wastewaters from electroplating operations. Each filter (500mm height x 100mm diameter) completely removed nickel from up to 50 L of 100ppm wastewater. Additional filters can be added at will to treat higher metal loads. The metal laden filters were regenerated repeatedly without filter performance deterioration.
The new technology bears the following competitive advantages:
a) Increased efficiency, particularly when working in low metal concentration wastewaters.
b) Low initial and operational cost.
c) Uncomplicated operation and maintenance.
Further research will contribute to the development and refinement of the product.
The biosorption filters will contribute to the pollution abatement of the natural water bodies receiving industrial wastewaters. The filters will be constructed from an abundant, inexpensive raw material. The amount of energy needed for filter production and operation is minimal compared to other conventional techniques for heavy metal detoxification.
The core group SME proposers will benefit by the application of the technology in the following ways:
a) They will significantly improve the management of their own wastewaters.
b) They will promote and market the biosorption filter technology.
Substantial savings for the SMEs are expected from:
a) Metal recovery and re-utilisation (including precious metals).
b) Water recycling.
In any case, compliance with environmental regulations is mandatory for the continued operation of these SMEs. The installation of the biosorption filter system will enable the partners to apply for ISO 14001 or 9002. This is expected to increase dramatically their market share and turnover.
