“…H 2 O 2 is an unstable oxidizing agent most commonly used as an inexpensive, household disinfectant and bleaching agent [18]. Additionally, at low concentrations, H 2 O 2 is an endogenous reactive oxygen species (ROS) which serves as an important signaling molecule in several plant functions, such as plant response to pathogens, abiotic stress, as a growth regulator and in low concentrations, can positively influence plant growth and yield [19,20].…”

Hydroponic production typically uses conventional fertilizers, but information is lacking on the use of organic hydroponic fertilizers. Development of microbial communities and biofilm that can reduce dissolved oxygen availability is a difficulty with organic hydroponics. One potential solution is the use of hydrogen peroxide (H2O2) which can reduce microbial populations and decompose to form oxygen. However, information is lacking on the impact of hydrogen peroxide on hydroponic crop performance. The aim of this study was to determine the effects of H2O2 concentrations in deep water culture hydroponics by assessing how it affects plant size and yield in lettuce (Lactuca sativa L.) “Rouxai”. In this experiment, three H2O2 treatments, namely the application of 0, 37.5 or 75 mg/L H2O2 to 4 L aerated hydroponic containers with either conventional or organic fertilizer, were compared. The containers had either fish-based organic fertilizer (4-4-1, N-P2O5-K2O) or inorganic mineral based conventional nutrient solution (21-5-20, N-P2O5-K2O), both applied at 150 mg/L N. Three replicates of each H2O2 treatment–fertilizer combination were prepared resulting in a total of eighteen mini hydroponic containers each with one head of lettuce. There were two growth cycles: fall 2018 and spring 2019. When added to conventional fertilizers, both 37.5 mg/L and 75 mg/L of H2O2 led to stunted growth or death of lettuce plants. However, when 37.5 mg/L of H2O2 was applied to organic fertilizers, the lettuce yield nearly matched that of the conventionally fertilized control, demonstrating that the application of H2O2 has the potential to make organic hydroponic fertilization a more viable method in the future.

“…Current research and usages of ozonated/H 2 O 2 water in recirculating hydroponic systems involve continuous injection of low concentrations rather than periodic influx of higher concentrations. Furthermore, the research primarily explores its impact on microbial levels with less information on crop yield [19][20][21][22][23][24].…”

“…Desalination plants are also used in water reuse context as discussed by FAO [8]. In addition, water applied for irrigation inside greenhouses [9] and hydroponics [10] can be reused in the same context as long as this water is considered polluted by the fertilizers' remains. This technique requires a mini plant for water purification.…”

Water plays a crucial role in the agricultural field for food production and raising livestock. Given the current trends in world population growth, the urgent food demand that must be answered by agriculture highly depends on our ability to efficiently exploit the available water resources. Among critical issues, there is water management. Recently, innovative technologies have improved water management and monitoring in agriculture. Internet of Things, Wireless Sensor Networks and Cloud Computing, have been used in diverse contexts in agriculture. By focusing on the water management challenge in general, existing approaches are aiming at optimizing water usage, and improving the quality and quantity of agricultural crops, while minimizing the need for direct human intervention. This is achieved by smoothing the water monitoring process, by applying the right automation level, and allowing farmers getting connected anywhere and anytime to their farms. There are plenty of challenges in agriculture involving water: water pollution monitoring, water reuse, monitoring water pipeline distribution network for irrigation, drinking water for livestock, etc. Several studies have been devoted to these questions in the recent decade. Therefore, this paper presents a survey on recent works dealing with water management and monitoring in agriculture, supported by advanced technologies. It also discusses some open challenges based on which relevant research directions can be drawn in the future, regarding the use of modern smart concepts and tools for water management and monitoring in the agriculture domain. INDEX TERMS Data analytics, internet of things, smart agriculture, water management, water monitoring, wireless sensor networks. II. FOUR CHALLENGES RELATED TO WATER MANAGEMENT IN AGRICULTURE We discuss four important challenges in water use in the agriculture domain (see Fig. 1). Each challenge motivates a significant shift from traditional water management solutions to smarter ones for higher efficiency, via the integration of modern technologies, e.g., WSN and IoT.

“…In many cases, lower-cost water sources are already being used, so the cost of water reuse should be compared with the cost of any available new water sources. The costs of water reuse vary greatly from place to place depending on location, water quality requirements, treatment methods, distribution system needs, energy costs [54], subsidies, and many other factors [11,28,50].…”

All around the world, water supplies are coming under increasing pressure as population growth, climate change, pollution, and changes in land use affect water quantity and quality. To address existing and anticipated water shortages, many communities are working to increase water conservation and are seeking alternative sources of water. Water reuse-the use of treated wastewater, or "reclaimed" water, for beneficial purposes such as drinking, irrigation, or industrial uses-is one option that has helped some communities significantly expand their water supplies. This review summarizes the main findings of the literature. The paper provides an overview of the options and outlook for water reuse in the world, discusses water treatment technologies and potential uses of reclaimed water, and presents a new analysis that compares the risks of drinking reclaimed water to those of drinking water from traditional sources. Involved technologies in wastewater treatment plant for drinking water purpose should be furnished with highly performant methods such as membrane processes (nanofiltration, reverse osmosis) and advanced oxidation processes (H 2 O 2 , O 3 , etc.). Treating efficiently wastewater at its source is the best "barrage" against pollutants diffusion through the nature as chemicals of emerging concern are detected in tap water.
