Boron

Reverse osmosis (RO) has been proved to be an effective technology in the treatment of low level radioactive wastewaters (LLRWs) in nuclear power plants (NPPs). However, particular attention must be paid to any possible negative influence of excessive boron on the performance of membrane units. In th

Despite appearing at relatively low concentrations, weak acids of various types have a significant impact on the design, operation and the quality of the product water in many RO (reverse osmosis) applications. During the RO process, weak acid species are simultaneously involved in interconnected tra

Based on experimental data, a simulation and optimisation of the adsorption Á microfiltration (AMF) process for boron removal from reverse osmosis (RO) permeate was done. An impressively low flow rate of the dry boron adsorbent of about only 54.3 kg h(1 is needed in the adsorbent recirculation loop

This study is focused on the application of the ion exchange Á submerged microfiltration hybrid process for boron removal from geothermal water containing high level of boron (8 Á 9 mg B/L). The goal of this study is to determine the optimum parameters such as feed flow rate, resin concentration and

The paper deals with evaluation of adsorption-membrane filtration (AMF) hybrid process in removal of trace amounts of boron from the first stage RO permeate. Finely ground boron selective resin, Dowex XUS 43594.00, was used as sorbent while polypropylene capillaries with pore dimension of 0.4 mm as

The main objective of this work was to investigate and compare the removals of boron from model solutions (boron as single solute in distilled and deionized water) and seawater using two commercial high rejection SWRO membranes. The impacts of dissolved solids in seawater and pH on boron rejection a

In the last years, boron and arsenic are gaining wide attention in the water treatment community due to their adverse effects both on human/animal health and on agriculture. As a consequence, nowadays, the number of water treatment plants equipped with boron and arsenic removal facilities is growing

Boron removal from aqueous solution by electrodialysis was studied as a function of solution pH, applied voltage, flow rate and initial boron concentration. TS-l-l0 electrodialysis equipment (Tokuyama) modified with rotameters was employed for experimental studies. It was obtained that the highest b

The main objective of this work was to investigate boron removal from seawater using two commercial high rejection SWRO membranes. The impact of solution pH, feed concentration, pressure, and cross-flow velocity on boron rejection and permeate flux was determined. The membranes used were the TorayTM

In this study, boron removal from aqueous solutions was examined using Dowex 2×8 anion exchange resin. The sorption behaviour of resin was investigated as a function of pH, contact-time and temperature, initial boron concentration of solution, resin dosage and effect of other ions. The maximum sorpt
