Résumé partiel
During the mid-1980s, a series of national surveys was conducted by the Water Research Commission (WRC). These surveys (also known as NATSURV reports) investigated water and wastewater management within the industrial environment of South Africa. These original NATSURVs have, however, become outdated. The WRC has, therefore, commissioned updates for these reports. The aim of this study is to gather relevant information, pertaining to water and wastewater management in the fruit and vegetable processing industry, by means of a national survey. The quality and scope of the knowledge acquired should be suitable to be included in the second edition NATSURV 19 (Water and Wastewater Management in the Fruit and Vegetable Processing Industry). As a means of comparison, an in-depth literature review was conducted before commencing with the surveying process. The literature review focussed on the various production processes found in the fruit and vegetable processing industry. Another key component of the literature review was detailing the various wastewater treatment methods available to the fruit and vegetable processing industry. An industry database was built using a combination of internet sources, industry databases and referrals. Thereafter, all 78 facilities included in the database were telephonically contacted in order to verify their operational status. An internet-based survey was then made available to persons with executive authority within each facility. Site-visits of selected facilities were being conducted simultaneously. Each site visit included an interview with a person possessing in-depth knowledge of the processes involved. A walk-through audit of the facility was also conducted during these site- visits.
