AGF Sand Media Filter
The AGF sand media filter system comprises multiple standard high-speed sand media filter tanks. With an inner water distributor and collector and a two-way automated three-way flush valve; this allows the backwashing of each tank in the system during normal operations. All are regulated by a completely automated system.
Depending on user needs, two vertical and horizontal configurations are available to treat water quality in circulating water systems for industrial or civil agricultural irrigation.
This product boasts a compact, automated design that can guarantee quality effluents of 0.5 NTU turbidity, with a filtration precision of 5 micron. The system is self-regulating and backwashing, providing users an efficient, cost-effective solution.
Filter media and flow
AGF utilizes a variety of standard filter media, but chiefly relies on natural sea sand and quartz sand. Both quartz sands are suggested to meet the desired filtration requirements.
| Filtration | Sand at bottom (mushroom-shaped collectors are covered) | Upper sand layer (12-38cm thick) | Recommended flow rate | Backwash flow rate |
| Coarse filter | 1.5-2.0 mm | 0.8-1.5mm | 30-50 m³/h | 30-40m³/h |
| Fine filter | 1.5-2.0 mm | 0.5-0.8mm | 15-25 m³/h | 25-30m³/h |
