Wastewater disinfection applying solar energy
(Corresponding) ZKERI E., Vourdoubas I., Katsivela E.
Topic:
Wastewater treatment
Solar Water Disinfection Process (SODIS) is a simple technology using solar UV-A radiation (wavelength 320-400 nm) and elevated water temperature to inactivate pathogens. In the present survey, the effect of solar radiation on the disinfection of domestic secondary treated wastewater from the...Read more

Coal fly ash zeolites as adsorbents for effective removal of heavy metals and dyes from contaminated waters
Zgureva D., (Corresponding) Boycheva S., Behunová D., Václavíková M.
Topic:
Wastewater treatment
Recently, the purification of enormous amounts contaminated industrial, agricultural and municipal waters increases the demands of low-cost and technologically feasible techniques. The application of natural zeolites in wastewater treatment is known from many years. A feasible approach for...Read more

Magnetite nanoparticles activated coal fly ash zeolites with application in waste water remediation
(Corresponding) Boycheva S., Miteva S., Trendafilova I., Zgureva D., Václavíková M., Popova M.
Topic:
Wastewater treatment
The application of zeolites in wastewater treatment is studied long ago but still many unexploited opportunities exist. Recent investigations on natural and synthetic zeolites in water decontamination are focused on the improvement of their adsorption and ion-exchange properties modifying them by...Read more

Systems improvement and energy savings program for the existing conventional extended aerobic treatment of domestic wastewater in compliance of DAO 2016-08 new general effluent regulations
Maceda M.
Topic:
Wastewater treatment
This is a system improvement and energy savings program for a Sewage Treatment Plant treating wastewater coming from a shopping mall operation. Wastewater from shopping mall is considered domestic wastewater, which needs a big volume of water, and produced big amount of wastewater. Generators of...Read more

Gravity-driven oil/water separation using PVDF-HFP electrospun nanofiber membranes
Mavukkandy M., Ibrahim Y., Almarzooqi F., Naddeo V., Alhseinat E., Karanikolos G., Banat F., (Corresponding) Hasan S.
Topic:
Wastewater treatment
With increasing industrialization and lenient waste disposal practices, oil-contaminated wastewater has become a significant environmental concern. Oil spills associated with oil exploration and transportation will continue to pose an ecological threat as long as we depend on oil for energy needs...Read more

Investigating the effect of different NaCl concentrations as draw solution used to concentrate synthetic municipal wastewater in a Forward Osmosis system
(Corresponding) Kappa S., Themeli E., Noutsopoulos C., Malamis S.
Topic:
Wastewater treatment
The main bottleneck towards resource and energy valorization of municipal wastewater is the low strength of sewage; characterized by low organic matter and nutrient concentrations. In this study, a bench scale Forward Osmosis (FO) system with a cellulose triacetate membrane (CTA) was used as a pre-...Read more

Evaluation of real bilge water toxic effects on methanogenic activity
(Corresponding) Gatidou G., Samanides C., Vyrides I.
Topic:
Wastewater treatment
Bilge water (BW), an oily residue that is accumulated at the bottom of vessels, is mainly generated from pipes’ and engines’ leakage and consisted of lubricating and diesel oil, cleaning solvents, oily sludge and other hydraulic/engine spills from seawater filtrations as well as fresh and seawater...Read more
Practical impediments to the effective utilization of Ballast Water Management Plan from Port facilities and Shipping practice
(Corresponding) BOVIATSIS M., Polemis D., Tselentis V.
Topic:
Wastewater treatment
Since the new Ballast Water Management Convention entered into force in 2017, the ballast water should be cleansed of any harmful aquatic organisms, pathogens, wastes or even bacteria, before being released into a new aquatic environment. For this purpose, the ships are required to carry i) a...Read more

Treatment and Reuse of Industrial Wastewater Using Reverse Osmosis System
(Corresponding) Ahmadzadeh-Kaleybar F., Emamifar M., Bagheri M.
Topic:
Wastewater treatment
From a few years ago, using reverse osmosis in water refinery and desalination, in order to provide clean water for necessary requirements has been considered as a common method. In the current study, the reverse osmosis, in the water refinery process of Miyaneh steel factory (northwest of Iran)...Read more
Investigative Study on the Effectivity of Plant-Based Coagulants for the Siltation Pond of an Aggregate Crushing Plant in Southern Luzon, Philippines
Angus F., (Corresponding) Clemente E., Ballesteros Jr. F.
Topic:
Wastewater treatment
Water quality and treatment are becoming of increasing concern. It is important to develop renewable bio-coagulants to treat turbid water. This study suggests plant-based coagulants as substitute for chemical coagulants. The plants used were Moringa oleifera (MO), Carica papaya (CP) seeds, and...Read more
