Towards a Holistic Approach for Small Island Tourism Analysis: The case of Camiguin, Philippines
(Corresponding) Reyes E.
Topic:
Environmental impacts of tourism and sustainable tourism development
Tropical small islands are perceived paradise destinations for most tourists, however, small islands are critical biosystems with finite, fragile and vulnerable yet unique set of resources. These features are not highlighted as a defining character that captures small islands spatial challenges and...Read more

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
(Corresponding) Chhetri R., Kokkoli A., Karvelas S., Andersen H.
Topic:
Wastewater treatment
Nitrification inhibition test is a standard method to test if the chemicals or samples received by wastewater treatment plant are toxic to the nitrifying bacteria in the wastewater treatment plant. Nitrification inhibition test based on ISO method ISO9509 or modified ISO9509 method (REFLAB method)...Read more

Peracetic acid disinfection: An effective way to reduce antibiotics resistant bacteria from raw hospital wastewater
(Corresponding) Chhetri R., Sanchez Urbina D., Lindholst S., Rickers C., Elkær T., Gade H., Skaarup J., Andersen H.
Topic:
Wastewater treatment
Risk of infection from antibiotic resistant bacteria from wastewater to the workers in the plant can be reduced by disinfecting wastewater. Peracetic acid (PAA) was used to disinfect the raw wastewater from hospital in pilot scale experiment. Batch experiment was conducted in parallel to confirm...Read more
Innovative methods of ground improvement for problematic transport earthwork materials
(Corresponding) Mavroulidou M., Safdar M., Gunn M., Gray C., Payne I., Garelick J., Purchase D.
Topic:
Environmental management and policies
The paper focuses on emerging (bio-) chemical techniques used to improve engineering properties of two problematic earthwork materials of the UK rail network to address transport earthwork infrastructure resilience in view of climate change. Studied techniques include novel cementing agents (e.g...Read more
A study of alkali-activated concrete mixes in seawater environments
Mengasini L., (Corresponding) Mavroulidou M., Gunn M.
Topic:
Marine environment and coastal management
This paper assesses the performance in seawater environment of concrete mixes based on alkali-activated (AA) cements; these are proposed as an alternative to Ordinary Portland Cement (OPC) to address environmental footprint of cement production and to find new uses for waste materials. The proposed...Read more

alkali activated cement concrete, seawater environment, durability, green construction materials, solid waste management
A comparative study of alkali activated slag cement concretes with carbonate and silicate activators.
Sanam I., (Corresponding) Mavroulidou M.
Topic:
Environmental management and policies
Alkali-activated cements are increasingly gaining interest as viable alternatives to Portland cement, because they are considerably reducing CO2 emissions compared to traditional Portland cements while maintaining or exceeding performance requirements commonly specified for construction...Read more
A comparative assessment of alkali-activated stabilisers including waste materials, for the treatment of swelling-shrinking soils
(Corresponding) Mavroulidou M., Gray C., Gunn M.
Topic:
Solid waste management
Swelling-shrinking soils (also known as expansive soils) experience very considerable volume changes upon changes in moisture content, thus causing major damages to lightweight structures, pavements, slopes and utilities. To counteract this problem chemical stabilisation of this type of soil with...Read more

(Corresponding) Shalaby M., Abdallah H., Alanezi A., shaban A.
Topic:
Water treatment
Nanofiltration membranes (NF) are considered and used extensively in seawater softening, food, textile, and mining industries for the removal of di-and multi-valents to increase RO lifetime by decreasing fouling rates, and chemical cleaning intervals. In this work, blend membranes of...Read more
Mixed Nanostructures/PES/ RO Membrane for Water Desalination
(Corresponding) Shalaby M., Abdallah H., Shaban A., Chetty R., Kumar M.
Topic:
Desalination
Different nanomaterials graphene, zinc nanorode and zinc nanosephere were used in membrane preparation. Polyethersulphone as a main polymer was blended with nanosoultions of these nanomaterials, then coated by composite coating layer consists of polyvinylacohol and titanium dioxide nanotubes to...Read more
Managing the risk of cyanobacteria through water quality characteristics analysis: A case study of two warm Mediterranean reservoirs
(Corresponding) Antoniou M., Kagalou I., Hadjiouraniou G., Daskalakis E., Tsiarta N., Chamoglou M., Polykarpou P.
Topic:
Lakes, rivers, estuaries and ecosystem health
This study correlated the trophic condition of two Mediterranean water bodies with different typology with their water quality characteristics. The two studied cases included Polemidia Dam, a reservoir enriched with tertiary treated wastewater in Cyprus and Lake Karla, a re-established reservoir in...Read more
