Abstract (sommario):

Abstract Model equations for prediction of process parameters of reverse osmosis for desalination of seawater were developed via mathematical derivation from basic equations for the reverse osmosis process. A model equation relating the interfacial solute concentration () with the process pressure difference () was developed. Taking the of reverse osmosis as the basic independent variable, further model equations relating other process parameters such as the solute concentration polarity , water flux , osmotic pressure , water output rate (q), power density (Pd) and specific energy consumption

Abstract (sommario):

The evaluation of a new air water generator (AWG) based on absorption and reverse osmosis is described. For the evaluation, an aqueous lithium bromide solution has been selected from a wide range of liquids as the absorbent. At high salt mass fractions, the aqueous lithium bromide solution has a low vapour pressure and a high osmotic pressure. The low vapour pressure ensures that the water vapour can be absorbed from the air, but the high osmotic pressure leads to high pressures over the membrane. Due to the high osmotic pressures, several reverse osmosis membrane modules are necessary and sal

Abstract (sommario):

Reverse osmosis (RO) desalination is a method of producing fresh water from seawater by a process similar to filtration, rather than by traditional evaporative distillation. A semipermeable membrane allows water molecules to pass through while blocking the passage of most other ions. The qualities of RO which make it attractive for naval and marine applications are its ability to operate on electric power alone, requiring no heat source; its comparatively low system weight to other methods of freshwater production at sea; and its ability to operate automatically, requiring minimal operator att

Abstract (sommario):

Reverse osmosis is one of the most prevalent methods of generating potable water owing to its low power usage, excellent rates of contaminant removal, simple design, large output capacity, and much cheaper initial and maintenance costs than comparable alternatives. In this review, the most important published research related to the reverse osmosis process was reviewed. It was found that the majority of reported studies were related to using the reverse osmosis process for water desalination and wastewater treatment. Research has proven that the reverse osmosis process is a very effective meth

Abstract (sommario):

With the increase in population and the scarcity of fresh water in the Middle East desalination has taken an important role in the provision of water for everyday use and for industrial purposes. Reverse osmosis water treatment process is of particular interest as it is one of the key processes in a desalination plant. The modelling of this process and the prediction of permeate flow is useful in better understanding the process. In the present study, an artificial neural network based model was developed based on plant data for the prediction of permeate flow performance. Plant data was colle

A survey performed over existing two pilot-scale and two full-scale RO desalination facilities to study the current status of boron rejection showed a highest rejection 85% leading to permeate boron concentration of 0.52 mg/L, and recent studies predicted a cost increase due to incorporation of boron reduction systems. Mathematical models were developed to study the process performance and related cost implications. The deterministic process model was verified with pilot-scale experiment performed using a single spiral wound module and was later modified to represent the full-scale design op

This thesis deals with water reclamation and water reuse in the South African water supply context. The overall objective of the study is to assess the potential role and feasibility of reverse osmosis as a water reclamation process. In order to achieve this objective a number of separate desk, laboratory and pilot plant studies were conducted. It was concluded from the first desk study that a significant potential role exists for reverse osmosis in the South African water economy, mainly for the treatment of industrial effluents and, in the longer term, for the reclamation of water from sewag

Abstract (sommario):

Thesis (MEng) -- Stellenbosch University, 2014.<br>ENGLISH ABSTRACT: When desalinating brackish water by reverse osmosis (RO) or other techniques, high overall water recoveries are essential to minimize brine production and the associated disposal costs thereof. As the overall water recovery increases, concentrations of sparingly soluble salts (e.g. barium sulphate, calcium sulphate) reach levels above saturation, especially near the membrane surface, drastically increasing the scaling propensity. Antiscalants are typically dosed into the feed water to prevent such scaling during RO desalinati

The integration of advanced technologies into existing water treatment facilities (WTFs) can improve and enhance water quality; however, these same modifications or improvements may adversely affect finished water provided to the consumer by public water systems (PWSs) that embrace these advanced technologies.

Abstract Conservation of water resources and the minimization of discharges are paramount in today’s industries. The reuse of process water effluents plays an important role in conserving water. This paper investigates the recycle of effluent process water from a metal finishing operation using reverse osmosis to provide make-up water for reuse. A case history demonstrates how membrane separation is used to produce water suitable for use and to minimize or eliminate aqueous discharges. This paper also examines the use of pretreatment chemicals to minimize membrane fouling.

Abstract The presence of silica in brackish water greatly complicates the reverse osmosis desalting process. Threshold limits of silica scale precipitation are difficult to predict as they are influenced by a large number of parameters. Another difficulty is the lack of a silica anti-scalant that can be confidently used to extend water recovery limits. Moreover, silica scales depositing on a membrane are difficult and costly to remove.

This research project introduced a novel membrane coating strategy to combat biofouling, which is a major problem for the membrane-based treatment of agricultural and municipal wastewaters. The novelty of the strategy is that the membrane coatings have the unique ability to switch reversibly between passive (antifouling) and active (antimicrobial) fouling control mechanisms. This dual-mode approach differs fundamentally from other coating strategies that rely solely on one mode of fouling control.
