[CEST2019_00938] Performance evaluation of a flat sheet self-forming dynamic membrane (SFDM) for municipal wastewater treatment containing organic micropollutants
by Millanar-Marfa J.M.J., Borea L., Castrogiovanni F., Napodano P., Hasan S.W., De Luna M.D.G., Belgiorno V., Naddeo V.

Membrane bioreactors gained increasing interest due to its small footprint and high efficiency. Nonetheless, high capital and operational cost of MBR remains a challenge. With the aim to reduce MBR cost, this study used Dacron mesh to form a dynamic membrane that serves as a substitute to conventional membranes to treat municipal wastewater containing organic micropollutants (OMPs). The SFDM system obtained COD, NH4-N and PO4-P removal of 95%, 47% and 14%, respectively.

[CEST2019_00937] Novel Polyethersulfone (PES) Alpha-Zirconium Phosphate (α-ZrP) Ion Exchange Mixed Matrix Membranes for Effective Removal of Heavy Metals from Wastewater
by Abdulkarim E., Ibrahim Y., Hasan S., Naddeo V., Banat F.

In this study, novel polyethersulfone (PES) alpha-zirconium (α-ZrP) ion exchange mixed matrix membranes were fabricated via phase inversion method using nano-sized alpha-zirconium phosphate (α-ZrP-n) and polyvinylpyrrolidone (PVP) as dispersant nano-additives in the dope solution preparation. The impact of α-ZrP-n loading on the removal of Cu(II), Zn(II), and Ni(II) from wastewater effluent was studied by varying the α-ZrP-n concentrations from 0.1 up to 1 wt.% while fixing the PES concentration at 10 wt.%.

[CEST2019_00904] 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
by Maceda Ma., Cleofas O.

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.

[CEST2019_00806] Treatment of High Strength Industrial Wastewater utilizing Canna X generalis in a Simulated Vertical Flow Constructed Wetland Set-up
by Heidi A., Ballesteros F., Esguerra G.

In the Philippines, DENR has mandated the regulation of oil and grease, COD, and TSS for automotive parts manufacturers. Wastewaters from industries have varying pollution strength that requires efficient treatment systems of combined physical, biological, and chemical processes. However, these methods tend to be labor intensive and costly. Constructed wetlands have become a popular treatment method for industrial wastewater because of its simplicity requiring less technical expertise compared to other technologies.

[CEST2019_00712] Nitrification inhibition test of salty wastewater containing Tetrakishydroxymethyl phosphonium sulphate (THPS), formaldehyde and methanol using salt-adapted nitrifying bacteria, an alternative test method to ISO method
by Chhetri R.K., Kokkoli A., Karvelas S., Andersen H.R.

Nitrification inhibition test is a standard method to test if the chemicals or samples received by wastewater treatment plants (WWTPs) are toxic to nitrifying bacteria in the wastewater treatment plant. Nitrification inhibition test based on ISO method ISO9509 or modified ISO9509 method (REFLAB method) cannot differentiate the toxicity between salt and toxicant in the sample, which is unrealistic for regulation of salty wastewaters that are treated in WWTPs with sufficient volume to dilute salts to harmless levels.

[CEST2019_00405] Quality Improvement of collected rain water by elimination of micropollutants to sea site settlements with the use of new technologies
by Kollias P.S., Kollias V.P., Kollias S.

The continuous increase of water needs in sea site settlements, created the need to collect rain waters in order to use them, after their treatment to achieve the necessary quality improvement. To realize that we need at first to mark the water sources in the neighboring area of the serviced district, in order to collect the necessary water quantities, for the covering of the existing necessities. One part of the sustained pollution is removed from the water treatment installations but the rest remains in the natural medium.
