How do pool sand filters work?

The pool sand filter is your easiest and simplest option to install and maintain if you want to keep your pool water clean and crystal clear.

It is an economic and ecological method, and you only need to change the sand when it stops performing its function.

In this post, we describe in detail how these filters work to help you decide if it is the best option for you. Keep reading!

 

Main characteristics of pool sand filters

This type of filter uses sand as a filtering agent inside its tank.to retain the impurities present in the pool’s water.

At GRE, we offer you a range of compact, easy to install and use pool sand filters. They do not require special care and can be fitted to any removable pool.

The sand filter monobloc holds a complete filtration set that includes:

– Pump.

– Filter (with a capacity of 4,000 liters per hour at 180 W power).

– 5-Way selector valve.

– Manometer (pressure gauge).

It is mounted on a plastic bench with all the necessary pipe fittings. Our pool sand filters are also certified under the European standard, guaranteeing compliance with the safety regulations in force.

 

Pool sand filter operation

This type of pool filter has a selector valve that enables it to perform several functions. They are:

  1. Backwash

In this position, the water inside the filter flows in the opposite direction of the filter and into the drain. This function removes any impurities from the sand filter. The process will be completed when the water being drained becomes clear (approximately 2 minutes). We recommend you use the backwash function at least once a week.

 

  1. Rinse

Upon completing the backwash process above, place the valve in the “Rinse” position for 30 seconds to completely rid the piping of any dirt/impurities. Once that is done, place the valve lever in the “Filter” position.

 

  1. Filter

In this mode, the water is filtered and returned clean through the return valve into the pool. This is the function/position the filter unit will remain in most of the time.

 

  1. Drain

In this position, the water goes directly into the drain without passing through the filter.

This option is ideal:

– If you notice a lot of dirt accumulated at the bottom of the pool.

– To lower the water level when (for any reason) it is above the skimmer.

– To drain the pool completely.

 

  1. Shut

In this mode, the water is shut off from the filter unit. It is recommended for winter or prolonged periods without use of the pool.

  1. Hola quería saber cuanto cuesta la depuradora de arena, gracias

  2. Buenas tardes,

    El precio varía en función de los m3 que soporte la depuradora por lo que necesita conocer la capacidad de su piscina para elegir la más adecuada. Le facilito el enlace donde podrá encontrar nuestros modelos en función del tamaño de la piscina: https://www.grepool.com/depuradoras/depuradoras-de-arena/cuba-o320-mm-4-m3-h

    Muchas gracias.

  3. Hola, me gustaría saber porque en modo filtración también se sale el agua por el desagüe, y cuando lo ponemos en modo cerrado tenemos que poner la manguera de desagüe por encima del nivel de agua de la piscina para que no se salga

  4. Buenas tardes Vicente,

    Esto puede ser por varias razones, dependiendo del tipo de piscina. Si es una desmontable con filtración GRE, no es normal, ya que si la válvula está en modo filtración, la parte de desagüe debería estar cerrada y sin salidas de agua. Si es una piscina enterrada, hay que mirar si el agua se llena automáticamente y por lo tanto puede que el nivel de agua esté demasiado alto y por eso el agua se vacía automáticamente. Le recomendamos que contacte con un especialista para que le de una respuesta más concreta.

    Muchas gracias.
    Saludos.
