Impact of hydraulic pressure and pH on organic fouling in pressure retarded osmosis (PRO) process
Desalination and Water Treatment, 2016 AbstractPressure retarded osmosis (PRO) is a promising membrane-based process for producing clean and renewable energy. Since the major driving force is the salinity gradient between the feed and draw solutions, PRO can operate without a large environmental footprint.

Desalination and Water Treatment, 2014 The pressure-retarded osmosis system with the spiral wound module for power generation has been studied numerically. The system includes draw channel, membrane, and feed-channel. The water flux and the solute flux across membrane were calculated. In addition, changes in concentration, flow rate, and pressure of channel-fluids were obtained.

Effect of fouling on performance of pressure retarded osmosis (PRO) and forward osmosis (FO) [PDF]
Journal of Membrane Science, 2018 Abstract A layered model is developed to describe mass transport through fouled membranes in pressure retarded osmosis (PRO) and forward osmosis (FO) processes. This resistance-in-series model accounts for salt and water transport through the active layer, support layer, external boundary layers, and the cake layer formed by foulants.

Supra and subgingival application of antiseptics or antibiotics during periodontal therapy
Periodontology 2000, EarlyView., 2023 Abstract Periodontal diseases (gingivitis and periodontitis) are characterized by inflammatory processes which arise as a result of disruption of the balance in the oral ecosystem. According to the current S3 level clinical practice guidelines, therapy of patients with periodontitis involves a stepwise approach that includes the control of the patient ...
