In the current climate change scenario, Mediterranean cities face heatwaves and reduced availability of freshwater alternated with intense precipitation events in short periods. The demand for water, especially urban tourism purposes, is rising, particularly coastal cities. importance integrating nature into cities, trees, has been studied its benefits adapting to improving quality life. However, water scarcity remains a limiting factor ensuring needs trees and, consequently, ecosystem services they provide. this study, we quantified (CO 2 sequestration storage, O production, air pollutants removal, hydrological effects as transpiration, intercepted avoided runoff) provided by vegetation Faro (Algarve, Portugal), detailed analysis three green spaces.

Since 2020 wastewater-based surveillance has quickly been established as an effective and cost-efficient tool for monitoring public health. In this Making Waves article, we argue that these programs must be grounded in principles of justice to achieve global water health equity. Ethics initiatives date have focused primarily on privacy, legality, institutionalised research reviews, often, if not exclusively, North America Western Europe. We draw from our interdisciplinary, multisectoral, international expertise experience develop a justice-centred framework surveillance. First, identify common concerns across diverse including: defining community, transparency accountability, uneven geographies. Second, political theorist Nancy Fraser's evaluate site-specific practices identifying maldistribution, misrecognition, exclusion. suggest offers approach evaluating just outcomes rather than specific regulations governing wastewater different unequal contexts.

In today’s ongoing rapid urban expansion, deforestation and climate changes can be observed mainly as unbalanced rain occurrence during the year, long seasons without any at all unordinary high temperatures. These adverse affect underground water levels availability of surface water. addition, quite a significant proportion drinking is used for non-drinking purposes. With several EU countries increasingly suffering from droughts, reusing quaternary treated wastewater help address scarcity. At European level, Regulation 2020/741 Parliament Council 25 May 2020 on minimum requirements reuse was adopted. This regulation foresees use recycled agricultural irrigation. article provides an overview various processes, such filtration, coagulation, adsorption, ozonation, advanced oxidation processes disinfection, treatment in order to remove micropollutants achieve reuse. According literature, most effective method with acceptable financial costs combination membrane filtration (UF or NF) UV disinfection. are relatively well known commercially available. also helps researchers identify key themes concepts, evaluate strengths weaknesses previous studies determine areas where further research needed.

The current treatment of wastewater has unintended negative environmental impacts. Conventional methods frequently involve the use harmful chemicals, generate disinfectant by-products, consume significant amounts energy, and produce wastes requiring additional efforts for safe disposal. Water stress exacerbated by contaminants emerging concern (CECs) climate change, is further straining aging systems. A slow sand filter (SSF), with ligno-cellulosic layers, offers a novel, promising, economic alternative reclamation. This review examines key SSF characteristics, obtained from recent studies, explores sustainable materials such as ligno-cellulose, companion. optimal design includes bed depth >0.6 m, particle effective size (D10) between 0.15 mm 0.40 mm, uniformity coefficient (CU grain ratio) ≤2.0. It established that SSF’s characteristic biolayer microorganisms enhances contaminant removal via biodegradation. While biofilm-based micropollutants proven mechanism, research needed to address CEC challenges. For example, inclusion sawdust in layers can reduce energy consumption compared conventional be recycled through thermal conversion, aligning circular economy principles. approach potential improve economies, contributing achievement UN Sustainability Goals.

The treatment and reuse of industrial water is a matter great interest, given the severe shortage resources. It widely acknowledged that power plants, particularly wet-cooled consume significant amount water. Therefore, research on circulating cooling system (CCS) return utmost importance. This study examined data CCS inlet (water body), makeup, parameters, calculated balance, predicted hydrochemical quality tower blowdown (CTBD). was conducted for an operating plant to propose effective scheme CTBD process cycle. Additionally, it evaluated possibility recycling in clarifier through laboratory modeling. cycle ensure environmental sustainability. Recycled used as supply tower, lime softening applied clean CTBD. According results, possible recover indicators from portion after treatment. values total hardness (TH) alkalinity (TA) play critical role limiting scale formation determining appropriate concentration cycles. model's implementation could potentially lead reduction up 25% plant's intake drainage requirements.
