A device (prototype) with a working volume of 200 L was used to deplete olive mill wastewater (OMW) of polyphenols. The OMW transformed into feedstock by means of the device was then used for feeding a lab-scale photobioreactor, just for testing the production of bioH2. The main novelty of this prototype consists in the combination of several adsorbent matrices and the exploitation of their syn...

Dissolving pulp mill wastewater called prehydrolysis liquor (PHL) obtained from steam (at 150-170C) treatment of wood had a total chemical oxygen demand (COD) of approximately 100 g/L contains mainly sugars, furfural, lignin, and acetic acid, poses a considerable wastewater disposal problem. Replacement of the current energy intensive disposal method (evaporation and use of recovery boiler) is ...

The separation of reactive, sulfur, and vat dyes from cotton dyeing effluent was investigated by a coagulation process using a cationic polymer electrolyte (PE). The coagulation of dyes was found to be considerably influenced by the amount of added PE and pH of the effluent. High degree of separation, (i.e.-90-99%) could be achieved for all the dyes. The secondary treatment of the PE treated (p...
