Hybrid Photocatalysis - Ultrafiltration oxidation process for a broad range of water treatment applications

A hybrid photocatalysis-ultrafiltration membrane system offers an integrated solution for simultaneous oxidation of organic substances and separation of suspended photo-catalyst nano-particles. This novel technology is implemented in a continuous, once-through, mode of operation with automatically c...

Sonozone Treatment On Wastewater To Be Reused

In our R&D project we studied the application of an hybrid disinfection-oxidation process, based on the synergism of two different technologies (sonication and ozonation), on wastewater to be reused. We put our attention on the treatment of complex municipal wastewater, as primary effluents, charac...

Hellenic Evaluation System for the ecological quality of rivers

The investigation of water quality is conducted widely through the use of biological indicators based on benthic macroinvertebrates. The developed Helenic Evaluation System (Artemiadou & Lazaridou, 2005) uses the biological characteristics of the composition of the community of invertebrates that li...

Preparation and study of coagulation properties of innovative reagents and their applications in environmental protection

These new flocculants are mostly inorganic compounds of polymerized ferrum (polyferric sulfate, PFS) and composite modified flocculants ferrum silicates (PFSiS), or organic polyelectrolytes (PFS-PAA). The action research project was divided into the following main sub-phases:

Pre-experiments of improved coagulation reagents

The objective of this research is to study the effectiveness of the new flocculation, coagulation reagents compound for the treatment of liquid waste with relatively low organic matter content (i.e. < 5 mg/L). The new reagents are derived from a combination of simple pre-polymerised salts of alumini...

Bromate Determination in Water Using Chlorpromazine after Correction of Chlorinating Agents and Humic Substances Interference

The research team tried to apply the method to natural water samples, but found that the presence of soluble humic substances resulted in positive interference giving high pseudobromate values, thus rendering the method unsuitable for bromate determination in natural water and restricting its use in...

Preparation, study of the properties and application of innovative coagulation reagents, based on aluminum, for water and wastewater treatment.

The aim of the project is the preparation, characterisation and evaluation of the coagulation performance of novel coagulation reagents based on aluminium for the treatment of water or wastewater. The new coagulants resulted after the combination of polyaluminium chloride (PACl) and various additive...
