La operaci\u00f3n de KLPP ha comenzado desde 1996 utilizando turbina de gas de ciclo combinado y la planta est\u00e1 contribuyendo actualmente con 675MW de capacidad de generaci\u00f3n de electricidad a la red. La capacidad de la planta para suministrar electricidad a la red de acuerdo con su obligaci\u00f3n en virtud del Acuerdo de Compra de Energ\u00eda depende de una serie de factores, incluido el suministro fiable de agua limpia con el fin de enfriar. En promedio, KLPP extrae 20.000 metros c\u00fabicos de agua tratada para su funcionamiento diario. Para un funcionamiento \u00f3ptimo y la vida \u00fatil de la planta, el agua debe estar lo m\u00e1s limpia posible con bajo contenido de sustancia org\u00e1nica o inorg\u00e1nica que afectar\u00eda el funcionamiento de la planta.<\/p>\n

Hay cuatro \u00e1reas principales de la planta donde se identific\u00f3 el potencial de mejoras considerables.
\n\u2022 La posibilidad de a\u00f1adir agua de perforaci\u00f3n al suministro de agua cruda
\n\u2022 Aclaraci\u00f3n del agua cruda antes de entrar en la planta
\n\u2022 Optimizaci\u00f3n del programa de dosificaci\u00f3n de floculantes\/pol\u00edmeros (tipo inc. y tasa de dosificaci\u00f3n)
\n\u2022 Cambio de los medios en los filtros de arena r\u00e1pidos a DMI65\u00ae[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text css=\u00bb.vc_custom_1593503610377{margin-bottom: 0px !important;}\u00bb]BORE WATER ADDITION<\/strong><\/p>\n

It was suggested that the area surrounding the plant be assessed for suitability and potential quality and quantity of several bores to add to the plant raw water supply. The addition of bores would not only provide greater flexibility in terms of seasonal blending with river water to ensure sufficient quantities of water in the dry season, could also be used to lower suspended solids and turbidity loadings on the plant during the wet season.<\/p>\n

There is a likelihood that there will be traces of iron and manganese in the bore water, but the use of DMI65 filtration media will remove this and provide an improvement to the usual mechanical filtration duties.<\/p>\n

CLARIFICATION<\/strong><\/p>\n

The high turbidity and suspended solids levels in the raw water could be greatly reduced by clarification prior to entering the water treatment plant. The existing plant is fixed in size and capacity, however a pre-clarification stage will dramatically reduce the load on the current plant.<\/p>\n

A traditional clarifier and upstream floc\/polymer dosing system to handle 1ML\/hr would cost well over USD $1M and take up a considerable land area to install and was therefore not practical in this case. With a very low retention time this type of system would also require very high chemical usage.<\/p>\n

POLYMER OPTIMISATION<\/strong><\/p>\n

A range of polymer samples were supplied during the site visit. Jar testing has been carried out using the range of samples and highlighted a particular polymer most suited to this raw water. A local polymer supply company is able to supply a very similar product in powdered form and at a very reasonable price that would suit the mixing\/batching system mentioned above.<\/p>\n

MEDIA CHANGE-OUT IN RAPID SAND FILTERS<\/strong><\/p>\n

During our visit one of the rapid sand filters was drained for inspection. The sand in the filters has never been changed and is now very hard-packed and is in need of replacement. The filter was filled whilst we were watching and the infiltration rate of the incoming water was very poor with most of the water just flowing across over the top of the sand and down through cracks in the hard packed sand rather than down through it. We proposed to replace the media with DMI65\u00ae filtration media<\/a>.<\/p>\n

The DMI65 will remove the existing and cope with any rise in iron or manganese levels that can be encountered in raw water sources with varying quality. The DMI65 requires a low level of free chlorine (0.2-0.3mg\/L) to activate the media. This is easily achieved as it only requires moving of the existing chlorine dosing point to just prior to the media filters. The chlorine residual will remain and still act as disinfection for the treated water lagoon.<\/p>\n

The DMI65\u00ae also provides the perfect filtration coefficient resulting in excellent mechanical filtration lowering suspended solids and turbidity levels.<\/p>\n

The addition of the DMI media and replacement of the filtration nozzles improved not only the quality of water from the media filters, but also the quantity of water through the filters.<\/p>\n

Sample Results<\/p>\n

\"\"<\/p>\n

With a peak NTU of 1000 and an average inlet TSS of 286 you can see that the outlet of lagoon B has been maintained generally around 80 NTU with an average of 86 NTU.<\/p>\n

OVERALL PLANT OUTPUT<\/strong><\/p>\n

The results from the plant post media filters after the replacement of the old sand media with the new DMI65 media have been consistently excellent.<\/p>\n

The expected results from the media filters after the upgrade were:<\/p>\n
