[CEST2019_00889] Impact of reuse of the purified wastewater on some properties of soil. Case study of Ain Defla station (Northwestern Algeria)
by Touil S., Richa A.

Purified wastewater (PWW) is a major source of water and nutrients for many farmers in arid and semi-arid climates. The aim objective of this study is to follow the change of soil characteristics i.e permeability porosity, total calcium, electrical conductivity (extract diluted) and pH before and after an irrigation event. Two plots were selected near wastewater treatment plant of Ain Defla, the first one irrigated by fresh well water and the second one by PWW.

[CEST2019_00792] Mine water management in abandoned mine sites: from waste to resource
by Loredo J.

Text Mine water usually supposes one of the most important environmental problems of the extractive industry, where water quality is dependent of a great number of factors relatives to the ore deposit characteristics and to the exploitation method typology. But if water quality by nature or after convenient treatments stays inside the acceptable limits, according to the legislative quality standards, mine waters could be used for different uses.

[CEST2019_00801] Grey Water and Rain Water as Alternative Sources of Flush Water and Irrigational Water in and around Households: A Case Study from Istanbul Atakoy District
by Beler Baykal B., Gursoy O., Aksoy Y., Samsunlu A.

Grey water and rain water are two options as alternative sources to alleviate water stress/scarcity across the world. This paper aims to investigate possible use of reclaimed grey water and harvested rain water from on-site premises as sources of flush water and irrigational water in and around households in the popular settlement district Atakoy of the water-stressed Turkish megacity Istanbul.

[CEST2019_00760] Installation of a sewer mining unit in the Athens Urban Tree Nursery
by Plevri A., Samios S., Lytras E., Papadopoulos K., Lioumis C., Lazari A., Tazes N., Monokrousou K., Makropoulos C.

Within the framework of the Horizon 2020, a European project called NextGen evaluates and champions transformational circular economy solutions and systems around resource use in the water sector. The Athens demo site is located in the Athens Urban Tree Nursery which is part of the Goudi Park, an area in the process of redevelopment and regeneration to become the key metropolitan park of the capital. The innovations that are being implemented within the project are the installation of a sewer mining modular unit for urban green irrigation at the point of demand with a capacity of 25m3/d.

[CEST2019_00633] Water microbiota in a recirculating aquaculture system for environmental sustainability and fish welfare
by Almeida D., Sousa Z., Magalhães C., Silva E., Blanquet I., Mucha A.P.

Recirculating aquaculture systems (RAS) are a promising technology of fish production to reduce aquaculture environmental impact. Water recirculation relies on the stability of physical, chemical and biological processes to increase biosecurity. Although, disruptions in RAS systems can cause fish disease outbreaks by opportunistic pathogenic bacteria with an economic impact. The aim of this study was to characterize the water microbiota across the different sectors of a flatfish (Solea senegalensis) RAS unit, and understand its relation with the water quality parameters.

[CEST2019_00657] Water reuse integration in the holistic water cycle
by Adin A.

Wastewater reclamation and reuse (WRR) is an emerging water generation tool for combating water stress. The objective of this paper is to develop a conceptual approach which will pave the way to WRR sustainable integration in a multi-resources regional or local system. For that purpose, a holistic Water Cycle Concept has been developed.

[CEST2019_00436] Advanced approaches to treat contaminants of emerging concern for water reuse
by Dionysiou D.

Contaminants of emerging concern (CECs) are frequently detected in treated wastewater effluent, because the traditional treatment train is not designed to eliminate them. The removal of CECs by conventional activated sludge is highly variable for different compounds depending on their biodegradability.

[CEST2019_00355] Technical optimization of a treatment process on ABE effluent by membrane technologies
by Stoller M., Bravi M., Russo P., Bubbico R., Mazzarotta B., Sed G., Moroni M.

In the last decades, the interest in biofuel production is sensibly growing as a good source of sustainable energy and a valid alternative to fossil ones. One of the most promising biofuel is butanol and might be produced by starting from different substrates, such as second generation ones, that have the advantage to be in the future more cost effective, as soon as the relevant production processes will be fully developed and optimized.

[CEST2019_00318] Greening walls for treatment and reuse of domestic greywater
by Boano F., Caruso A., Costamagna E., Fiore S., Demichelis F.,Ridolfi L., Galvao A., Pisoeiro J., Rizzo A., Masi F.

In this study, we describe a sustainable system for treatment and reuse of grey wastewater in urban areas through vertical green walls constructed on unused surfaces of buildings. The system integrates the benefits linked to the introduction of green spaces in urban areas with the advantages connected with the reuse of purified greywater (non-potable reuse) and the reduction of potable water use, allowing a sustainable use of water resources. We constructed a vertical green wall composed of modular panels with 12 vegetated pots per panel.

[CEST2019_00320] Recovery and separation of valuable metals (copper and zinc) from acidic mine waters by ion-exchange resins
by Vecino X., Reig M., López J., Valderrama C., Gibert O., Cortina J.l.

Mining wastewaters, containing heavy metals such as copper (Cu) and zinc (Zn), have a huge impact on the environment due to they are not biodegradable and tend to bioaccumulate in plants or living organisms. Therefore, in this work the performance of ion-exchange and solvent-impregnated resins were compared for the separation and recovery of valuable metals (Cu, Zn) from acidic mine waters (AMW). Lewatit 207 as an ion-exchange resin, and an impregnated resin containing Di-2-ethylhexylphosphate, named Lewatit 1026, were evaluated for extract both metal ions.

[CEST2019_00321] Recovery of sulphuric acid and valuable metals (Zn, Cu and REE) from acidic mine waters using nanofiltration
by López J., Reig M., Vecino X., Valderrama C., Gibert O., Cortina J.L.

Acidic mine waters (AMWs) contains moderate concentrations of sulphuric acid, relatively high concentrations of metals (Al, Fe, Cu and Zn) and minor amounts or rare earth elements (REE). The established management routes for AMW treatment include a neutralization-precipitation step, which implies a high cost due to the reagents consumption. Nanofiltration (NF) membranes are emerging as an alternative to conventional methods to treat AMW due to a good passage of mono-charged ions (e.g.
