After the United Nation’s International Maritime Organization banned the use of organotins in antifouling products, organic booster biocides were introduced as alternatives to these compounds. The purpose of this study was to measure concentrations of the antifouling agent Irgarol 1051, its major metabolite M1 (aka GS26575), and other antifouling pesticides (diuron, chlorothalonil, dichlofluani...

BACKGROUND Biofouling, the colonization of artificial and natural surfaces by unwanted microorganisms, has an important economic impact on a wide range of industries. Low cost antifouling strategies are typically based on biocides which exhibit a negative environmental impact, affecting surrounding organisms related and not related to biofouling. Considering that the critical processes resultin...

This paper presents a comparative study on the antifouling properties of poly(ethylene glycol) (PEG)-based polymer coatings prepared by surface-initiated polymerization (SIP). Three types of poly(oligo(ethylene glycol) methyl ether methacrylate) (POEGMEMA) polymer thin films of approximate 100 nm thickness were grafted from a catechol initiator that was immobilized on a Ti substrate. OEGMEMA mo...

AIM The aim of this study was to determine the pressure where oral soft tissue resistance will be overcome resulting in soft tissue emphysema and to measure the safety of an antifouling device for a videoscope used during minimally invasive periodontal surgery. MATERIALS AND METHODS Resistance was measured in vitro in porcine tissue. One study arm measured palatal tissue resistance to air app...

The control of biofouling is required to improve membranes performances for water filtration. In this context, developing bioinspired approaches modify and give them antifouling properties an interesting alternative. study, we elaborated new anti-biofouling by coating with vanillin, a natural bioactive molecule acting as Quorum Sensing Inhibitor (QSI). First, the adsorption vanillin filtration ...

Membrane reusability determines the economic sustainability of separation process. However, membrane was deduced by antifouling properties, while actual reuse performance using palm oil mill effluent (POME) is rarely reported. This study investigates nano-Fe3O4/PVDF (PVDF1) for POME treatment. The chemical oxygen demand (COD), total suspended solid (TSS) permeate, molecular weight cut off (MWCO...

Abstract Lack of access to potable water and abating levels ground level demands the reuse unconventional sources after remediating it in a sustainable way. In this context, purifying brackish, land sea seems feasible solution ever-growing population. work, novel composite membrane was fabricated by 'layer-by-layer' self-assembly poly-dopamine (PDA) polystyrene sulfonate (PSS) supported on high...

High organic materials in palm oil mill effluent (POME) can result serious water pollution. To date, biological treatment has been used to reduce the environmental risks of these effluents prior their discharge into streams. However, effluents’ dark brownish colour remains as a significant issue that must be addressed, it affects overall quality water. Although membrane technology frequently ad...
