Solar Evaporation System Using Spray Pipe Method

EasyChair Preprint no. 8708

Abstract

Evaporation of water using a spray pipe is required to expand the contact between hot air and water surface so that the rate of evaporation of water becomes faster. Salt production in the case of solar evaporation may take weeks to obtain salt. This study aims to observe the correlation of flow rate and evaporation time on salinity by considering several potential factors. The experiment was carried out in two stages, the first stage on a small scale where spray evaporation was carried out in an evaporation pond with an area of ​​1x2 m², seawater rate 0.8 – 2.0 L/min, seawater volume 100 L. The second stage of spray evaporation is carried out on an evaporation pond of ​​3x15 m, a flow rate of 0.3-0.6 L/s, and a seawater volume of 220 L. Observation of the evaporation time for 30 h at an evaporation rate of 0.6 L/s obtained a salinity of 22.6 Be while at a rate of 2L/min it could reach a degree of salinity 23.8Be within 90 h.
