Product catalog summary

Operating Principle
The continuous sand filter operates by continuously removing dirty sand from the active sand bed using an air-lift pump. This pump draws contaminated sand from the bottom of the filter and transports it to the washing chamber at the top. Impurities are separated from the sand using a patented washing system that employs a counter-current stream of raw water. The cleaned sand is returned by gravity to the top of the sand bed.

Key Characteristics
- Unique continuous back-washing system using raw water.
- High efficiency and reliability in removing suspended solids, including colloidal particles.
- Simple and reliable external sand air-lift system for easy maintenance.
- Low pressure drops allow for gravity feed.
- Low capital and operating costs.

Construction Materials
All wetted parts are made of 304 stainless steel, with special materials available upon request.

Sectors of Application
- Surface water clarification.
- Drinking water treatment.
- Primary and tertiary filtration in municipal/industrial wastewater treatment plants.
- Cooling water treatment in the metallurgical industry.
- Algae removal.
- Pre-treatment for membrane ultra-filtration and ozonisation plants.
- Final treatment upstream of active carbon systems.

Technical Data
The document provides technical specifications for various models of filters, detailing filter height, diameter, net filtration area, and sand bed height.

filtrasand Principio di funzionamento Operating principle La sabbia sporca viene rimossa in continuo dal letto ﬁltrante attivo grazie all’azione di una pompa ad aria, che la preleva dal fondo del ﬁltro, sollevandola ﬁno alla camera di lavaggio (lavatore) posta alla sommità del ﬁltro stesso. La separazione delle impurità dalla sabbia avviene nell’esclusivo sistema di lavaggio brevettato. La sabbia viene ripulita grazie all’azione di un ﬂusso di acqua grezza che si muove in controcorrente rispetto al moto gravitazionale di ricaduta della sabbia verso la sommità del letto ﬁltrante. L’acqua grezza...
