Special Issue Information

Dear Colleagues,

Clean water is one of the most important natural resources on Earth. Wastewater, which is spent water, is also a valuable natural resource in the world. However, wastewater may contain numerous contaminants and, thus, cannot be released back into the environment until these contaminants are removed. Untreated wastewater and inadequately treated wastewater may have a detrimental effects on the environment and harmful effects on human health. Water quality engineering addresses the sources, transport, and treatment of chemical and microbiological contaminants that affect water. Our objective is the treatment of wastewater such that the treated wastewater meets national effluent standards for the protection of both the environment and public health.

This Special Issue seeks contributions on advanced technologies applied to the treatment of municipal and industrial wastewater and sludge. Of specific interest are contributions that deal with recent advances in the following topics: municipal wastewater, industrial wastewater, and sludge treatment technologies; the health effects of municipal wastewater; risk management; energy-efficient wastewater treatment; water sustainability; and water reuse and resource recovery.

Local communities in many parts of the West Bank, Palestine have very limited water resources available for irrigation. In addition, since these communities are traditionally agricultural communities, water shortage and the lack of innovation in the agricultural sector led to loss of jobs in this sector. This in turn led young people to start looking for jobs in different sectors and even increased migration to urban centers. The reuse of treated wastewater can provide a viable solution to irrigation water shortage. It can help in creating jobs in the marginalized communities in the West Bank, especially in areas under full Israeli control (Area C according to the Oslo Accord). Furthermore, it is important to select crops that can resist the effects of climate change and create revenue for the farmers at the same time. In this research, we studied the impact of irrigating marigold (Tagetes erecta), which is a flower plant commonly used in the Palestinian market, with treated wastewater from the Nablus West Wastewater Treatment Plant (NWWTP). The quality of the treated wastewater, as indicated by parameters such as COD, BOD5, pH, EC, and TSS, shows its suitability for agricultural reuse. With low levels of organic matter, a near-neutral pH, and minimal suspended solids, the water poses minimal environmental risks and is ideal for irrigation, though monitoring for salinity buildup is necessary. Twenty-six marigold plants were planted, half of them were irrigated with the treated wastewater and the other half with tap water. Observations of length, number of roses, rose size, days to flower, and flowering days were recorded for both cases. The statistical analysis of the results shows that there is no significant difference between marigolds irrigated with treated wastewater and those treated with tap water, in terms of Plant Height, Rose Number and Rose Diameter.
