Water treatment wastewater

Chlorine is also widely used in industrial applications. In water/wastewater treatment, for example, it is used in the disinfection unit process. Large quantities of chlorine gas (stored in one-ton cylinders or railroad tank cars) used in these treatment processes is a major concern of those tasked with ensuring plant security.

Membrane contactors (MCs) are another interesting emerging membrane technology for desalination. MCs are devices that bring two phases (gas/liquid, liquid/liquid or liquid/gas/liquid) into contact at the entrance of pores (Fig. 2.1). MCs are today most commonly employed in the production of ultrapure water, wastewater treatments and water purification, as well as being used to control the concentration of several non-volatile solutes in aqueous solutions, such as salt and sugar in fruit juices and blood treatments. 

Production of ultrapure water, wastewater treatment and water purification (Boi et al, 2005 Gryta et al, 2006 Gugliuzza et al, 2010 Lawson and Lloyd, 1997 Macedonio and Drioli, 2008). 

Abstract The configurations and performance of photocatalytic membrane reactors (PMRs) assembled with membranes (also photocatalytic type) and/or suspended photocatalyst are described. Examples of the application of PMRs in water/wastewater treatment as well as in photocatalytic synthesis are shown. An outUne of the modeling of PMRs is presented with a brief economic analysis future trends in PMRs are also discussed. 

Key words photocatalytic membrane reactors, photocatolytic membrane reactor performance, water/wastewater treatment, photocatalytic synthesis.

XYZ Industries, a water-products chemical manufacturing industry, serves primarily the southeastern United States. Currendy, one Central Environmental Laboratory performs laboratory services for water/wastewater treatment plant customers. Further, the Central Environmental Laboratory (CEL) also services analytical programs including phosphorus removal, municipal storm water management, and specialized metal and organic analyses. 

General uses are in water/wastewater treatment and in the - paper and sugar industries. Starch is used in bauxite extraction (aluminum production). Guar is used in gold and uranium recovery (- mining chemicals). 

Solar-driven large-scale photoreactors are mainly used for water/wastewater treatment and disinfection.
