Preliminary Assessment on Water Quality of Different Wastewater Using Solar Water Distillation Technique

Abstract

In rural and isolated areas, there are limited clean and fresh water sources, which could be an issue for the people living in those areas. The use of solar distillation is used to treat the wastewater as an alternative to the fresh water sources. Thus, this study will determine the water quality of two different wastewater using solar water distiller and evaluates whether the treated water comply to the standard limit of drinking water from the Ministry of Health, Malaysia (MOH). The stormwater and greywater were used as water samples for the study. The physical properties investigated were temperature, colour, and odour while the chemical properties were total dissolved solids (TDS), ammonia, chlorine, hardness and pH value. The performance of solar water distiller was examined by considering the quality as well as the quantity of treated water. The relationship between the surrounding temperature, humidity and the volume of water collected was observed and recorded. The physicochemical parameters of the water after the treatment lies within the standard of MOH. Thus, the results demonstrated that the solar water distiller has potential as an alternative sustainable water treatment method.

Assessment of river water quality improvement due to riverbank filtration (RBF) mechanism

“…There are several parameters that need to be examined and quantified for the WQI and the selection of the parameters are varied according to standard used in different countries. Most of the common parameters such as biochemical oxygen demand (BOD), chemical oxygen demand (COD), suspended solids, ammoniacal nitrogen were evaluated based on the nature of catchment or surrounding area [3]. Results from agriculture catchments could present higher nitrogen-based values due to excess of fertilizers and pesticides [4].…”
