Antiscalant removes need for acid in wastewater RO
Field trials of a new scale-inhibiting chemical for use with reverse-osmosis membranes in wastewater reuse plants show that, at a low dose rate, it can increase the solubility of calcium phosphate by over one hundred times, obviating the need for using dangerous and costly acid. Current design practices for large effluent reuse projects are focused on a combination of removing phosphate by precipitation prior to the RO plant and acid dosing to reduce pH to 6.0 and hence increase calcium phosphate solubility to prevent fouling. Conventional antiscalants are ineffective at high phosphate and high recovery rates, and the only other option has been to dose large quantities of acid to reduce feed pH to below 6.2. Reducing the pH from 7.5 to 6.0 on a 2,700 m /day plant would require 0.5 to 1 ton of 95% sulphuric acid per day. Handling this quantity of acid is an environmental, health, safety and logistical problem that many plant operators would like to move away from. The results from the field trials show that using a highly active threshold inhibiting antiscalant such as Genesys PHO at a low dose rate of 2 -5 mg/L can increase the solubility of calcium phosphate by over one hundred times. This article appeared in D&WR magazine's August/September 2008 issue.

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.
