Abstract

A mobile fine spray unit, utilising a spill-return atomiser has been developed for the purpose of decontamination within healthcare environments. The unit must be able to spray uniformly onto any given surface, providing ‘mist like’ coverage. Any streaking patterns on the surface during or after spray application would jeopardise the efficiency of delivering the decontaminant. Thus it is pertinent to understand the behaviour of droplets impacting on various surfaces, and particularly the conditions that cause streaking. Within this investigation four sample surfaces; steel, acrylic, glass and laminated wood have been sprayed separately using the spill return device with a substitute MRSA disinfectant liquid. Through experimentation the optimum spray input conditions for the atomiser: distance, time and pressure required to uniformly coat various surfaces without the occurrence of streaking have been obtained.
