“…Another interesting result is the positive attitude of farmers towards the use of treated waste-water in Valencia, unlike the case study by Dare and Mohtar [13] where farmers are unsure about the safety of the resource. Finally, it is interesting to remark the importance of reducing fertilizer inputs in the plots, which can lead to a successful experience as in the case described in Italy by [35].…”

One of the most important challenges that agriculture faces is sustainable water management and its adaptation to climate change. This adaptation is more important in regions where recurrent draughts and overexploitation of water resources happen. However, historical irrigation systems, such as the Real Acequia de Moncada (RAM) in Valencia, have found innovative approaches to deal with this phenomenon. This paper analyzes the case of Massamagrell and Puçol, which reused the treated waste-water of the closest waste-water treatment plant (WWTP). The study focused from a circular economy perspective on the technological, agronomical, and social implications of this decision. Results show that there are clear benefits for both farmers and WWTP managers. On the one hand, additional nutrients and regularity in their water supply benefit farmers. On the other, WWTP managers can reuse the treated effluent in the system, contributing to the closure of the water cycle and avoiding pumping the treated water into the sea. However, more detailed information and coordination is needed among the different stakeholders. Questions regarding the illegal connection of waste pipes with the traditional irrigation or the payment of pumping costs for reuse have gone unanswered, and there is a need for better reflection from all stakeholders.

“…Many Mediterranean countries are suffering great periods of drought, so the reuse of industrial waters for agriculture would solve a major problem of water shortage, in addition to directly providing nutrients to the soil (Libutti et al, 2018). …”

Table Olive Wastewater: Problem, Treatments and Future Strategy. A Review

The table olive industry produces a high quantity of wastewater annually. These wastewaters are very problematic because of their characteristics of high organic matter, high phenolic content, high salinity and conductivity. The quantities in which they are produced are also a serious problem. The worldwide production of table olives reached 2,550,000 tons in the last five campaigns, with the European Union contributing to 32% of total production. The problem of these wastewaters is focused on the Mediterranean area where the highest quantity of table olives is produced and to a lesser extent on the United States and South America. Countries like Spain produce around 540,000 tons of these wastewaters. At present, there is no standard treatment for these wastewaters with acceptable results and which is applied in the industry. Currently, the most common treatment is the storage of these wastewaters in large evaporation ponds where, during the dry season, the wastewater disappears due to evaporation. This is not a solution as the evaporation ponds depend completely on the climatology and have a high number of associated problems, such as bad odors, insect proliferation and the contamination of underground aquifers. Different studies have been carried out on table olive wastewater treatment, but the reality is that at the industrial level, none has been successfully applied. New and promising treatments are needed. The current review analyzes the situation of table olive wastewater treatment and the promising technologies for the future.

“…Wastewater can be reused for potable or nonpotable purposes. Among nonpotable purposes, reuse in agriculture has gained prominence, since this sector consumes more than 50% of global fresh water (Libutti et al, 2018;Pedrero et al, 2010;Sanctis et al, 2016).…”

Reuse of wastewater is a practice that has been employed all over the world, mainly in agriculture, where the main aim is to reduce the demand for water and provide nutrients. However, these waters for reuse often have excessive amounts of pathogenic microorganisms, requiring a specific disinfection step even after being subjected to a purification process. Thus, this research aimed to evaluate the potential use of calcium hypochlorite and sodium hypochlorite as disinfectant agents for the sanitary effluent of the treatment system based on constructed wetlands for later reuse. Disinfection tests were carried out in batch, using three dosages of hypochlorite (5, 10 and 15 mg.L À1 ) and different contact. In all disinfection tests, inactivation of indicator microorganisms (total coliforms and E. coli) was considered effective for the two disinfectant agents adopted, satisfying the criteria for reuse according to the World Health Organization (WHO). There was no formation of trihalomethanes after disinfection tests. Water Environ. Res., 90, 2100Res., 90, (2018.
