[CEST2019_00835] Phase Diagram Modeling of a Multicomponent Aqueous Solution of Katwe Salt Lake, Uganda
by Lwanyaga J.D., Kasedde H., Kirabira J.B.

A methodology is developed to compute the phase diagram of a hexary system and to determine the mineral precipitation sequence upon removal of water. The methodology is applied to construct the phase diagram and precipitation sequence of the system (〖Na〗^+,K^+)(〖Cl〗^-,〖SO〗_4^(2-),〖CO〗_3^(2-) & 〖HCO〗_3^-) in water. The thermodynamic model chosen is the Extended UNIQUAC. A 3D grid is constructed in order to solve this model in MATLAB. On the basis of this grid, a 3D phase diagram is calculated and a Jänecke projection is obtained.

[CEST2019_00286] Microbiological treatment of water by cold plasma at atmospheric pressure
by Cubas A.L.V., Machado M.M., Santos J.R., Moecke E.H.S.

Ensuring the world's population access to drinking water is one of the millennium's challenges, for although our planet is made up of 70% of water, poor distribution and water quality are problems that concern world leaders, being among the objectives of development 2030 agenda set by the ONU. The proposed work aimed at the microbiological treatment of water through cold plasma technology at atmospheric pressure, the control to confirm the efficiency of the treatment was through the analysis of thermotolerant coliforms.

[CEST2019_00706] Arsenic Removal Using Electrocoagulation Process
by Vaiyakone P.,Soriano R., Morales-Corpuz M.V.A., De Sales L.

Contamination of water resources with Arsenic poses serious health concerns because of its toxic and carcinogenic nature. Detection of Arsenic at concentrations higher than 10 parts per billion (ppb) in some Philippine water resources confirmed the need for further studies on the contamination and for the investigation of potential treatment technologies.

[CEST2019_00773] Feasibility of reuse filter backwash water as primary/aid coagulant in coagulation-sedimentation process for synthetic effluent
by Mazari L., Abdessemed D.

The purpose of this study is to evaluate the feasibility of reusing filter backwash water (FBWW) from the water treatment plant (WTP)as a substitute for the conventional coagulants (primary coagulant) in the coagulation-sedimentation process applied for synthetic effluent.The coagulation effect on the elimination of the turbidity and UV254 was investigated by treating synthetic effluent using FBWW as a substitute for conventional coagulants.

[CEST2019_00852] Biosorption of Mn(II) ions from water solutions by natural sorbent: equilibrium study
by Mustafa E., Aliu F., Atkovska K., Kuvendziev S., Dimitrovski D., Bozhinovski Z., Marinkovski M., Lisichkov K.

In the modern society, the problem of the treatment of natural and wastewater resources and their management, is becoming very important.
Of particular interest is the definition of adequate and sophisticated procedures for the treatment of natural and wastewater resources, regardless of whether the source of pollution is of geogenic or anthropogenic origin.

[CEST2019_00257] Successful use of UV light driven photocatalytic oxidation for the removal of an emergent water contaminant
by Sescu A.M., Favier L., Lutic D., Ciobanu G., Harja M.

The degradation of a new anti-epileptic drug, named levetiracetam in aqueous solution has been investigated by heterogeneous photocatalysis, under UV light irradiation. For the photocatalytic assays, the photocatalytic activity of two different commercial catalysts (TiO2 Aeroxide® P25 and TiO2 Kronos uvlp 7500) was compared. The influence of some operating conditions (catalyst dosage, UV light irradiation, initial pollutant concentration, pH and water matrix was studied) and the main kinetic parameters were determined.

[CEST2019_00270] Water resources management in education for sustainable development
by Tzaberis N., Paraskeva D., Tatarakis N.

Issues relating to water resources are included among the most serious environmental problems. Pollution and deterioration of the receiving surface water and groundwater, mainly from human activities, pose an immediate threat to natural ecosystems and the functions of biosphere reserves, the balance of which is a prerequisite for the survival of every life form on the planet. In this light, the aim of the current study is to record second grade high school Rhodes students’ knowledge of matters concerning water.
