Nanocellulose membranes could efficiently separate oily wastewater because of their super-hydrophilic and underwater super-oleophobic property nano-porous structure. However, the practical application storage nanocellulose is limited by low water permeation flux easy corrosion bacteria, respectively. Herein, with high permeate antibacterial were fabricated grafting tetrakis(hydroxymethyl) phosp...

INTRODUCTION Developed using focus groups, the Oily Skin Self Assessment Scale (OSSAS) and Oily Skin Impact Scale (OSIS) are patient-reported outcome measures of oily facial skin. OBJECTIVE The aim of this study was to finalize the item-scale structure of the instruments and perform psychometric validation in adults with self-reported oily facial skin. METHODS The OSSAS and OSIS were admini...

OBJECTIVE To develop the content for two new patient reported outcome (PRO) measures to: a) assess the severity of symptoms; and b) the impact of facial skin oiliness on emotional wellbeing using qualitative data from face to face, and internet focus groups in Germany and the US. METHODS Using input from initial treatment satisfaction focus groups (n = 42), a review of relevant literature and...

BACKGROUND A novel implementation of a hybrid membrane bioreactor (HMBR) has been studied in this paper. It is utilized as combination of rotating biological contractor (RBC) and an external membrane, as a new biological system for oily wastewater treatment. METHODS Chemical oxygen demand (COD) and total petroleum hydrocarbon (TPH) as factors of Biodegradability has been evaluated. They are b...

Two types of adsorbents were used to treat oily wastewater, activated carbon and zeolite. The removal efficiencies of these materials were compared to each other. The results showed that activated carbon performed some better properties in removal of oil. The experimental methods which were employed in this investigation included batch and column studies. The former was used to evaluate the rat...

Due to the frequent oil spill accidents and pollution of industrial oily wastewater, fouling has become a great challenge polymeric membrane ion-selective electrodes (ISEs) for applications in oil-contaminated areas. Herein, simple approach is proposed enhance oil-fouling resistance ISEs by surface modification zwitterionic polymer-based underwater oleophobic coating. As proof-of-concept, class...
