| Abstract |
One of the methods for on-site disposal of wastewater from individual homes is by evaporation. Two types of evaporative disposal systems have been investigated in this study; evapo-transpiration (ET) beds and mechanical evaporation units. Twenty nine test lysimeters of 0.22 cubic meters volume each were utilized to evaluate the effect of design and operational parameters for ET beds. The variables studies were wastewater loading rate, effect of the weather variables of evaporation and rainfall, ET sand size, evaporation rate as a function of the water saturation depth, and the transpiration contribution of surface vegetation. A design method is presented along with cost data and an analysis of the national application potential of this type of system. The evaporation of wastewater using mechanical systems was studied using a pilot scale unit. Two types of evaporation designs were evaluated. Design equations were established for both units. Cost data and analysis of national application potential is also presented. |
