Presently boron-rich chemical landfill leachate originating from Tarnowskie Góry is being treated by boronselective ion-exchange resin. Since the boron concentration in this feed water type is relatively high (approx. 70 mg of B/L), the IE column post-regeneration lyes, that are strongly acidic and... 70 mg of B/L), the IE column post-regeneration lyes, that are strongly acidic and contain up to 2.5 g of B/L, utilization cost increases the boron removal cost to a large extent. Thus, based on the authors’ previous research, an attempt was made to propose a low-cost method for utilization of th ...

... Boron is biologically an essential nutrient for many plants but high boron concentrations in irrigation water cause toxic effects whereas low abundances require boron addition to maximize crop yields. High boron levels in... require boron addition to maximize crop yields. High boron levels in drinking water can be also toxic to humans. There is no easy method for the removal of boron from waters and wastewaters. One or more method may be applied according to boron cocentration in medium. For boron removal, mai ...
Desalination 223 (2008)

In this study removal of boron from aqueous solutions by adsorption was investigated and experimental design was applied. Cerium oxide was used as adsorbent. In the first part o ...

Orthoboric acid dissociation, which affects boron rejection in RO membranes, depends on salinity, temperature and pH. Lately, increasing demand of permeate low boron concentration raises questions... temperature and pH. Lately, increasing demand of permeate low boron concentration raises questions regarding the optimal method for boron removal in both technical and economical aspects. Several methods were presented in previous papers for boron removal, using RO membranes (SW & BW RO), a ...
Desalination 223 (2008)

Both pressure driven and electro-membrane processes show better boron removal efficiency when carried under alkaline conditions when the boric acid is ionized to a large extent. Even under such conditions th ...

... design options, provide recommendations based on permeate quality and process design, and improve the quality of information for the selection of boron removal treatment. The tool provides appropriate design guidelines for the impact of post-treatment on design and operation of SWRO plants prior t ...
