Abrasive Water-Jet Technology Waste and Its Processing Possibilities

Popis výsledku v původním jazyce

The paper is dealing with the environmental research of waste material rising from abrasive water-jet cutting. The waste material from the overfull collector tank in the Laboratory of the Liquid jet was studied. Potential environmental hazard arising from the normal disposal of the waste material was also discussed. The analysis of dried slurry samples was carried on by electron microprobe. Twenty one samples of waste mixture from various parts and depths of the tank were analyzed and compared with samples of non-used abrasive material. It was proved that abrasive material which had undergone the process of cutting was significantly impaired. It should be recycled in some cases but careful economic calculation taking into account all additional costs connected with separation of suitable abrasive fraction and its drying should be necessary. X-rays analysis provided information about chemical composition of the waste material. Most of the sludge was from abrasives, namely almandine. Higher contents of magnesium oxide, lower contents of aluminum oxide and higher contents of iron oxide, however, was probably caused by presence of other abrasive materials, such as olivine or zirconium which had been also used for cutting during the working period of the system. No potentially harmful material was detected by the X-ray analysis. It can be therefore stated that waste material from the water-jet cutting can be disposed on a common landfill without any restrictions.
