Appropriate Technology for Wastewater Treatment in Coastal Tourist Areas

Abstract

The composition of wastewater from tourist areas is discussed. Since such a significant part of the contaminants in wastewater is associated with particles, a good particle removal should be the first step in the treatment of wastewater. In coastal areas it is recommended that coagulation with lime should be used. Special attention is drawn to the lime/seawater process where 2-5 vol-% of seawater is added to the influent resulting in several process improvements. For low-cost treatment the use of the lime/seawater process in a pond system is discussed.
