Introduction of Solar Drying Technology to Trinidad and Tobago

Malabar Wastewater Treatment Plant
Trinidad and Tobago

Sustainable wastewater solids management constitutes a serious challenge to the overall initiative of improvement of the wastewater systems by the local authorities in Trinidad and Tobago. The solids treatment approaches must be focused on the effectiveness of the processes and its durability. The selected approach must also integrate local and regional settings, as well as current and future environmental limiting conditions. It is concluded that the proposed process of solar drying will allow measurable scientific, environmental and economic benefits. Based on the analysis of the local weather conditions and estimated solids production rate of 17,600 tonnes per year, a total of 6 solar dryer cells covering an area of 7,450 m2 are required. The biosolids produced from the process is expected to have a minimum solids content of 70% and to have a significant vector attraction reduction. This fully automated and simple technology will enable minimum operator’s attention. Source: WEFTEC 2009 Proceedings
