“…Desalination technologies include several processes that may be classified based on the type of energy used, namely thermal and none-thermal desalination (e.g., reverse osmosis, crystallization, and electrodialysis), as shown in Figure 6a [51], and the desalination technologies themselves are classified into two categories: water separation and salt separation (Figure 6b) [51]. Wastewater treatment may be classified into primary, secondary, and tertiary schemes, as shown in Figure 7 [52,53].…”

Global climatic change intensifies the water crisis, particularly in arid and semi-arid regions. In this regard, the provision of enough water for irrigation is a serious dilemma because the agricultural sector consumes the largest amount of water (70% withdrawal and 90% consumption). In this review, we have summarized recent innovations that have emerged as unconventional techniques to supply adequate water for irrigation purposes. We present the principles and basics of seven approaches: the Sahara Forest Project (SFP), water extraction from the air (WEA), aquifer recharge, the treatment of marginal water using a magnetic field, desalination and wastewater treatment (DWT), electro-agric technology (E-AT), and the Toshka Project. The SFP is currently being utilized in Aqaba, Jordan, and DWT is considered a common practice worldwide, whereas some of these innovations are still under investigation to ensure their feasibility for large-scale applications, such as E-AT. The Toshka Project is considered a wonderful idea that utilizes the water stored behind the High Dam in Lake Nasser, Egypt. Several approaches have been adopted to reduce the amount of water being used for irrigation, as the current amount of freshwater is insufficient for the requirements of increased agricultural consumption, particularly in hot, arid, and semi-arid regions.

Water pollution is a global problem that can be a threat to the environment and human health, which is why efficient technologies are required for the treatment and comprehensive management of residues from wastewater treatment. In this sense, the present study used different filtration media such as zeolite, pumicite, tezontle, dolomite, ground corn straw, coconut fiber and biocalcium to analyze the physical-chemical interaction of these materials and the components of graywater from laundry in a simple filtering process. Four filter columns with different bed layers, same graywater and a filtration rate established by each filter were installed and operated at laboratory scale and in parallel. The pollution reduction was from 70.2% - 98% for selected parameters (COD, TSS, TDS, PO4 and NO3) in filter columns. Thus, filters with different arrangement of unconventional filtration media are efficient in purifying greywater.

“…India, which accounts for 18% of the world's population, only has access to 4% of the global freshwater resources, and an overwhelming 80% of the available supply is used for agriculture [1]. In the 21st century, one of the most pressing global challenges is the unequal access to abundant, clean water [2]. According to estimates, around forty percent of the world's population will be affected by water scarcity during the subsequent five decade [3].…”

The study investigated the potential of sand and activated charcoal filtration systems to enhance water quality for irrigation by treating aerated sewage effluent from. Setup involved a 60 cm deep sand filter connected as the inlet to another 30 cm deep sand filter and this filter linked as the inlet to a 30 cm deep charcoal filter. These filters were operated in series at hydraulic loading rates (HLR) of 60 m/h and 10 m/h. Notably, operating the filters in series at an HLR of 10 m/h yielded superior effluent water quality compared to an HLR of 60 m/h. System achieved significant removal efficiencies for turbidity, BOD5, COD, Total Nitrogen (Total-N), Total Phosphorous (Total-P) with 71.9%, 54.4%, 71.9%, 44.4%, 39.1%, and 42.9% with a 90 cm deep sand filter at an HLR of 10 m/h, and also with a combination of sand and charcoal filters at an HLR of 25 m/h system achieved 81.6%, 80.3%, 63.5%, 47.5%, and 64.3% respectively. We also examined the chemical characteristics of both untreated and treated sewage water samples, revealing a hierarchy of cation and anion prevalence as follows: Na+ > Ca2+ > Mg2+ > K+ for cations, and Cl- > HCO3- > SO42- > CO32- for anions. Our study demonstrates that the combination of aeration and sand filtration effectively ensures safety by preventing water body pollution and unpleasant odours with high-quality treated wastewater suitable for sustainable agricultural use.
