A large-scale pilot distribution study was conducted to investigate the impacts of blending different source waters on distribution water qualities, with an emphasis on metal release (i.e. corrosion). The principal source waters investigated were conventionally treated ground water (G1), surface water processed by enhanced treatment (S1), and desalted seawater by reverse osmosis membranes (RO)....

As more and more structural materials are used in marine and offshore service, studies on the effects of fouling organisms on corrosion and cathodic protection phenomena have gained renewed importance. This communication describes the common fouling organisms of Tuticorin harbour and their possible association in corrosion processes. Earlier studies on fouling in Tuticorin waters are restricted...

The definition of coastal forest shelterbelts in urban landscapes is highly complex. Growing of Casuarina equisetifolia as a small shelterbelt on the beach in Hambantotota City was implemented to protect the beautiful natural sand dunes, preserve visual amenity and be a barrier to seawater salt spay. The casuarina shelterbelt has become popular because it was the only undamaged area in Hambanto...

A new method for dehalogenation of trihalomethanes (THMs) by a low-cost and highly effective micro-alloyed aluminium composite (MAlC) in a semi-flow system (SFS) was studied. Addition of micro-alloyed elements significantly accelerated the rate of Al corrosion and enhanced reduction activity by destabilising the oxide film. THM dehalogenation by the MAlC followed pseudo first-order kinetics wit...

Abstract The corrosion of aluminum alloys (AA) caused by fungi has been considered as the typical reason causing failure aviation materials, but its mechanism is still unclear. In this work, AA 7075 induced Fungus Aspergillus terreus with continued organic carbon starvation was investigated in artificial seawater. Results indicate that A. can survive and form a biofilm on surface, then accelera...

The effect of temperature (from 288 to 308 K) and concentration sulfide ions (up 40 ppm) on the corrosion behavior AISI 304L 316L stainless steels in seawater was studied with measurements open-circuit potential, linear potentiodynamic polarization, electrochemical impedance spectroscopy. An increase pollutant negatively affects stability at open circuit (the resistance, compactness, thickness ...
