1344/F67G reagent-free filtration unit

The reagent-free filtration unit removes dissolved iron, manganese and hydrogen sulfide from water, along with turbidity and color, bringing the water to the required standards. Inside: a fiberglass housing laminated with polyethylene on the inside, an automatic control valve, granular filter media, a supporting gravel layer, and a drainage-distribution system.

The media oxidizes dissolved iron and manganese directly: passing through it, they convert to an insoluble form and precipitate as sediment, which is retained within the media bed. No reagents are needed for this — the accumulated sediment is flushed to drain by backwash, which also restores the filtering capacity of the media. The frequency of backwashing depends on the combined content of iron, manganese and hydrogen sulfide in the source water. Housings from 8 to 13 inches are fitted with 3/4″ and 1″ Runxin valves rated up to 4.5 m³/h, all top-mounted.

Design 1344/F67G: 13×44″ housing, automatic Runxin F67G valve, up to 4 m³/h, 1″ connection, top mounting. The valve is rated for filtration — backwash of the media without reagent. Weight 15.72 kg.

Configuration within the line: vessel size 1344 (13×44″) with control valve Runxin F67G. On the same vessel size 1344 (13×44″) the line also offers Runxin F56E, Runxin F67C3, Runxin F67C and Runxin F67P. The same control valve Runxin F67G is fitted on 0844, 1054, 1044, 1252 and others.

On vessel size 1344 the closest alternatives to Runxin F67G are Runxin F56E (valve capacity up to 2 m³/h instead of up to 4 m³/h, connection 3/4" instead of 1", weight 13.63 kg instead of 15.72 kg), Runxin F67C3 (valve capacity up to 4.5 m³/h instead of up to 4 m³/h, weight 15.39 kg instead of 15.72 kg) and Runxin F67C (weight 15.39 kg instead of 15.72 kg).
