En el Reino Unido, se estima que un tercio de todas las quejas de los clientes relativas al agua potable est\u00e1n relacionadas con la decoloraci\u00f3n del agua (Cook et al., 2005). Estas quejas socavan en gran medida la confianza de los clientes en las empresas de agua.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text css=\u00bb.vc_custom_1593484138974{margin-bottom: 0px !important;}\u00bb]Iron and Manganese contamination of water have long been considered to only lead to aesthetic problems, in that they are secondary contaminants that have little or no adverse health effects. However, research conducted by Wasserman et al. (2006) indicated a relationship between increased Mn concentrations in drinking water and reduced intellectual functions of children. Increased levels of Iron and Manganese concentrations have been found to be the main cause of drinking water discolouration (Slaats, 2002). Furthermore, discoloured water could also lead to coloured stains on laundries and sinks, increased treatment costs, reduced treatment capacity and increased pumping costs. Water with high concentrations of Iron and Manganese has been found to give water an unpleasant metallic taste and vegetables cooked with it become dark and look unappetizing (Herman, 1996).<\/p>\n

High Iron and Manganese levels can lead to non-compliance with drinking water regulations. The drinking water standard for most jurisdictions for iron is 0.3 milligrams per liter (mg\/l), and the standard for manganese is 0.05 mg\/l respectively. The quality of water changes as it travels from source to consumers in Water Distribution Networks (\u2018WDNs\u2019). Although water companies generally set post-treatment targets of Fe and Mn to about 3% of their respective MCLs, low concentrations of Fe and Mn still enter the network and gradually accumulate on pipe walls within WDNs. Given the wrong conditions, such as high flows created by a water main burst or high diurnal consumption of drinking water, these accumulated particles may subsequently lead to water discolouration and end up in customers\u2019 taps.<\/p>\n

In order to begin the process of oxidation of the iron (and manganese) in solution DMI-65\u00ae is designed to operate in the presence of chlorine or other oxidants. In this process the oxidant removes electrons and is consumed in<\/p>\n

the process. The operator needs to ensure that there is a 0.1 \u2013 0.3 ppm free chlorine residual in the effluent water. Chlorine, fed as sodium hypochlorite or bleach (12.5% NaOCl), is the preferred oxidant since it is relatively inexpensive, readily available around the world and it is effective. It also performs the vast majority of any disinfectant process.<\/p>\n

Unlike ion exchange resins where higher regenerant dosages will increase the ion exchange capacity, NaOCl residuals or concentrations higher than required to oxidize the Iron and Manganese do not increase the oxidative properties of the media. Additionally, since the media is often used to pretreat waters prior to an RO system a higher free chlorine residual would require more extensive post treatment to reduce the residual and protect the membranes from chlorine attack.<\/p>\n

DMI-65\u00ae has been certified to the US Standard of NSF\/ANSI 61 for Drinking Water System Components<\/a> and for use in England and Wales Under Regulation 31(4)(a) of the water supply (Water Quality) regulations 2010 and has also been tested by many other water treatment authorities and laboratories<\/a>.[\/vc_column_text][vc_empty_space height=\u00bb20px\u00bb]

George Municipal Water Works, Sud\u00e1frica, utiliza m\u00e1s de 550 toneladas m\u00e9tricas de DMI-65\u00ae. El agua de George es altamente coloreada que contiene \u00e1cidos h\u00famicos y f\u00falvicos \u2013 el color de agua cruda es aprox. 800 unidades de color PtCo. Se cree que este tipo de agua es una de las m\u00e1s dif\u00edciles de filtrar. La eliminaci\u00f3n de hierro es muy eficaz independientemente del pH. El hierro residual m\u00e1s alto encontrado fue de 0,01 mg\/L. La eliminaci\u00f3n de manganeso tambi\u00e9n es muy eficiente. El manganeso restante m\u00e1s alto encontrado fue 0,06 mg\/l Mn se elimina mejor a pH 8 m\u00e1s alto. El beneficio adicional de la extracci\u00f3n de aluminio incluso en el pH m\u00e1s alto. La turbidez m\u00e1s alta registrada fue 0,06 NTU. Seg\u00fan nuestras pruebas de laboratorio, el color m\u00e1s alto fue de 4 mg\/l PtCo, pero la mayor\u00eda de las veces el color era inferior al color del agua destilada comprada en una farmacia de George. La planta funciona desde principios de enero de 2007 y sigue teniendo excelentes resultados. George Municipal Water Works, utiliza el mismo DMI-65\u00ae medios filtrantes durante m\u00e1s de 13 a\u00f1os, sin fallas ni disminuciones en el rendimiento.<\/p>\n<\/blockquote>[vc_empty_space height=\u00bb20px\u00bb]

La Planta Municipal de Tratamiento de Aguas de Witbank en Durban, Sud\u00e1frica, consta de 18 grandes filtros de arena r\u00e1pida que utilizan 1200 toneladas de medios filtrantes para eliminar el hierro y el manganeso de la fuente local de agua subterr\u00e1nea. Los especialistas locales en tratamiento de agua y DMI-65\u00ae agente, Water Technologies Cape, demostraron el rendimiento y los beneficios de costos de la actualizaci\u00f3n del sistema a DMI-65\u00ae, mediante un exitoso ensayo piloto en 2018. Las mejoras a la planta comenzaron en 2019 y se espera que est\u00e9n terminadas a finales de 2020.<\/p>\n<\/blockquote>[\/vc_column][\/vc_row][vc_row css=\u00bb.vc_custom_1593496115589{margin-top: 15px !important;}\u00bb][vc_column]
