Trade effluent treatment turns sweet for Munitech Munitech has been appointed to design and construct a trade effluent treatment plant at the Candy Tops sweet manufacturing plant in East London.The appointment calls for treatment process design, plant design, construction and plant commissioning and the project is scheduled for completion by June 2009. Expansion plans for the Maragra and Ubombo Sugar Mills Bosch Projects was commissioned by Illovo Sugar to undertake a front end package study for both Maragra (Mozambique) and Ubombo (Swaziland) Sugar Mills at the end of 2007. andy Tops discharges effluent, with an organic loading equivalent to that generated by a population of 18 000 people, to the municipal sewerage system. The effluent constitutes a significant portion of the treatment load on the Buffalo City Municipality wastewater treatment plant and it was decided that the Candy Tops effluent should be pre-treated before discharge to the City. C “One of the main challenges in the development of a cost effective treatment process is the degradation of the carbohydrate rich effluent without generating excessive sludge” says Project Manager Cindy Wells. “Laboratory trials were conducted to understand the effluent characteristics and how the effluent would behave under biological treatment. The trials indicated that an aerated lagoon with an optimised retention time would effectively meet this goal. The aerated lagoon also gives a degree of process flexibility in accepting slugs of very high strength effluent.” Munitech has drawn on its many years of operations and maintenance experience to provide a low maintenance, operator friendly design that will meet the client’s objectives for years to come.

T he purpose of the study was to perform preliminary engineering and costing for the expansion of the factory from 167 tch to 230 tch. This study is now complete and the Illovo Sugar Board has approved the expansion programme and Bosch Projects has been appointed as the preferred consultant for the engineering, procurement and construction and management of this project. The project, headed by Nico Wentzel, is planned for two phases, with the second phase due for completion in time for season start-up in April 2010. The Ubombo project requires detailed engineering and costing for the expansion of the factory from 410 tch to 580 tch and the building of cogeneration plant. Vivian Gough is leading the project team and the front-end package will be completed early in 2009. Candy Tops factory with the site for the effluent treatment plant in the foreground.

A further social spin-off of the project was the transfer of plumbing repair skills to 10 local residents of Tembisa, in the form of intensive training as well as on-site experience. O The ceremony was attended by SBA’s Managing Director – Max Stemele and Project Manager - Ramona Reddy. The residents of Tembisa treated their audience to a colourful array of entertainment with gum boot dancers, other traditional and modern dancing and singing. This event evoked a true sense of “Ubuntu” among all those present. n 8th August 2008, SBA had the privilege to be part of an auspicious EMM project hand-over ceremony. This occasion saw the successful culmination of the first phase of a pilot programme in Tembisa, which was aimed at reducing the water consumption of indigent households by repairing / replacing leaking plumbing fixtures as well as imparting water conservation awareness education to the household residents. The approach was based on the 80/20 principle, where the highest 4 Contact: Ramona Reddy: [email protected]
