GLASS FILTER MEDIA & SILICA SAND LOSS PRESSURE IN WATER FILTERING

The concepts of pressure loss and pump pressure are not always as clear as we think.

Glass filter media generates less pressure  than silica sand inside the filter and this is the main reason for saving energy.

Water column and weight

Pressure: It is the weight of the column of water existing per surface unit.

Manometers: (pressure measures) usually show you the pressure inside the filter in Kg/cm2.

Manometers –

If we have a one square centimetre column 10 meters high, this will weigh 1 kilogram.  1kg/cm2 = 10 meter water column.

 

 

As an example:

If we place a manometer on a pump, that must pump water up ten meters, it will show 1kg/cm2 (=10 meters water column). Now if we placed the manometer at the outlet at the bottom of a pool at two meters deep, it will show 0,2kg/cm2 (=2 meters water column)

It´s important to distinguish between inlet and outlet pressure .

The difference between the inlet and outlet pressure is the pressure loss given by the filtering material.

The average pressure loss is 0,6kg/cm2 using silica sand, and 0,05kg/cm2 using Glass Filter Media.

This small pressure loss difference between medias, is where the energy saving capacity lies.

The relation between the hight of the water column (pump pressure) with silica sand and glass filter media in swimming pools. Also known as glass filtering in pressure filters.

Energy consumption with silica sand & glass filter media

The pump manufacturer gives you a consumption curve, with a constant pressure. For example 0,5kg/cm2.

So if the pump performs within this range, it will consume the amount stated by the manufacturer. But if the pressure generated by the filter doubles the pump pressure, the electric consumption of the pump will be double also

A good example would be: A vehicle that consumes 7 liters every 100 kilometers. If you measure it for 100 kilometers downhill and then another 100kmts uphill. The consumption of the vehicle will vary depending on the power that is required to move it.

Meanwhile during downhill the consumption would be almost zero, during uphill the consumption will rise notoriously, even if the manufacturer indicates that the vehicle consumes 7 liters every 100 kilometers at a certain speed.

Nature Works en Smagua 2012

Smagua
Stand de Nature Works en la feria Smagua de Zaragoza

Aprovechamos la participación de Nature Works en Smagua  para hacer un pequeño resumen de las características de este medio filtrante de alta tecnología desarrollado por el Departamento de I+D+i del Grupo Camacho.

 

Optima
calidad
de filtración

Disponemos de  productos específicos desarrollados para cada aplicación industrial: aguas potables, desalinizadoras, acuacultura, aguas residuales, arcillas…

Nature Works en ZaragozaDurabilidad extrema: la tecnología de calibración proporciona una partícula poliédrica libre de poros, grietas y aristas lo que la hace muy resistente. Además evita la compactación y el apelmazamiento. Se utiliza un solo tipo de grano con lo que ante eventuales reparaciones de filtro se retira y se vuelve a colocar fácilmente.

Máxima higiene:

es un producto aséptico

donde no prolifera el biofilm.
