Sentence examples for waste lubricant from inspiring English sources

The removal rate of 10 wt% waste lubricant oils using continuous air injection was given in Table 1.

This can be explained by, during injection of air flushing enhanced by surfactant solutions, the waste lubricant oils entrapped in soil pores were migrate because the interfacial tension between waste lubricant oils and the surfactant solution became low enough to force the blobs or ganglia of waste lubricant oils to move away.

The removal of poured waste lubricant oils from soil using air flushing with and without surfactant were carried out using laboratory scale model.

Furthermore, to recover the free phase of the waste lubricant oils in the treatment process it must be disposed of in accordance with applicable requirements.

Therefore, the pulsed air flushing mode was applied with coarse soil contaminated with 25 and 50 wt% waste lubricant oils in presence of 3 wt% nonionic surfactant.

Both of continuous (direct injection) and pulsed air flushing modes (on/off intervals) were applied to remediation course soil contaminated with 10 wt% waste lubricant oils in absence and presence of 3 wt% surfactant concentration.

Huge amount of wasted lubricants has become a great nuisance of environmental issues.

In addition, surfactants are capable of forming aggregates known as micelles, thus solubilizing waste-lubricant oil.

Waste-lubricant oils were collected from different factories and companies and were used as pollutant.

The increased solubility may increase the potential removal of trapped waste-lubricant oil droplets.

The ability of surfactant solutions to solubilize the waste-lubricant oil was investigated by mixing 30 ml surfactant solutions at concentrations ranging from 0.01 to 0.05 % with 0.5 ml waste-lubricant oils.
