PESU membranes in municipal water treatment applications

Here he looks at applications for municipal water treatment and claims improved virus removal and twice the permeability of PVDF membranes. This article first appeared in the November/December 2009 issue of Desalination & Water Reuse magazine.

Advantages of Polyethersulfone (PESU) membranes for pretreatment for SWRO applications

Membrane pretreatment for large-scale seawater desalination has grown rapidly in the last few years. Existing examples seem to show that the additional cost can be more than recouped in reduced chemical costs alone, but there are also environmental advantages. This article is the first of two discussing the advantages of polyethersulfone (PESU) membranes for filtration duties in water treatment. This article will start by considering general advantages of membrane use together with the reference and experience position, and then examine the particular benefits of PESU in terms of treated water quality. The final sections include a review of membrane pretreatment costs and environmental impact in comparison with conventional pretreatment technology. The second article, to be published at the beginning of 2010, will consider the advantages in using PESU membranes in municipal water applications.

High-flow cartridges provide safety filter solution for RO

In recent years, considerable progress has been achieved in membrane technology in China. It has been widely used in many fields, including seawater desalination, power plants, metallurgic, petrochemical, and municipal and wastewater reuse. This article looks at the use of safety filters for RO systems and how a high-flow filter can avoid build-up of microorganisms and consequent frequent filter change. A paper factory project provides a case study. Significant advantages including high flow-rate and long service-time help Horizon's RZ filter cartridge to occupy an important position in safety filtration for the membrane water-treatment market in China. It displays superior applicability to those large-scale and super large-scale plants operated in recent years. At the same time, RZ filter cartridges have shown fine performance when handling raw water with complicated quality or large fluctuations. Compared with regular cartridges, RZ filter cartridges provide an excellent solution to safety filtration of membrane water treatment because of their longer service life, smaller investment and lower change-out cost. This article appeared in the May/June issue of D&WR magazine.
