Treatment of MSW fly ashes using the electrodialytic remediation technique

In the present work the electrodialytic remediation technique is applied for the treatment of fly ash, a hazardous by-product resulting from the incineration of municipal solid waste. Results are presented for an experiment conducted for 40 days at 38 mA, with a continuously stirred cell. Experimental parameters monitored include voltage drop, pH and electrolyte’s volumes. Evolution of heavy me...

ELECTRODIALYTIC REMEDIATION OF CCA-TREATED WOOD IN LARGER SCALE _____________ *Iben

A pilot plant for electrodialytic remediation of CCA-treated wood in larger scale has been designed and tested at DTU. Several process parameters were investigated, and it was found that the use of collecting units and soaking of the wood prior to the electrodialytic process had a positive influence on the remediation process. There is a tendency towards easier remediation of wood chips < 2cm, ...

Ultrasonic washing of textiles.

We present the results of experimental investigation of ultrasonic washing of textiles. The results demonstrate that cavitation bubbles oscillating in acoustic fields are capable of removing soils from textiles. Since the washing performance is mitigated in a large washing bath when using an ultrasonic transducer, we propose a novel washing scheme by combining the ultrasonic vibration with a co...

Electrodialytic removal of Cd from biomass combustion fly ash suspensions.

Due to relatively high concentrations of Cd, biomass combustion fly ashes often fail to meet Danish legislative requirements for recycling as fertilizer. In this study, the potential of using electrodialytic remediation for removal of Cd from four different biomass combustion fly ashes was investigated with the aim of enabling reuse of the ashes. The ashes originated from combustion of straw (t...
