A study of influences of the workers' compensation and injury management regulations on aviation safety at a workplace.

As the aviation industries developed, so too did the recognition that there must be an effective regulatory framework to address issues related to the workers' compensation and rehabilitation. All employees would like to work and return home safely from their workplace. Therefore, the efficient management of workplace injury and disease reduces the cost of aviation operations and improves flight safety.

Combined BAC and MIEX pre-treatment of secondary wastewater effluent to reduce fouling of nanofiltration membranes.

Biological activated carbon (BAC) and magnetic ion exchange resin (MIEX) were used to pre-treat secondary wastewater effluent (SWWE) and assessed for their capacity to reduce fouling of a nanofiltration membrane. BAC pre-treated water facilitated a lower but a steady flux while MIEX treated water resulted in a higher but a rapidly declining flux. Their combined use increased average flux from 58 to 89%.
