1252/F67Q1 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 1252/F67Q1: 12×52″ housing, automatic Runxin F67Q1 valve, up to 4.5 m³/h, 1″ connection, top mounting. The valve is rated for filtration — backwash of the media without reagent. Weight 16.06 kg.

Configuration within the line: vessel size 1252 (12×52″) with control valve Runxin F67Q1. On the same vessel size 1252 (12×52″) the line also offers Runxin F71B, Runxin F67G, Runxin F67C3, Runxin F71P and others. The same control valve Runxin F67Q1 is fitted on 0844, 1035, 1044, 1054 and others.

On vessel size 1252 the closest alternatives to Runxin F67Q1 are Runxin F71B (valve capacity up to 2.0 m³/h instead of up to 4.5 m³/h, connection 3/4" instead of 1", weight 12.39 kg instead of 16.06 kg), Runxin F67G (valve capacity up to 4 m³/h instead of up to 4.5 m³/h, weight 13.22 kg instead of 16.06 kg) and Runxin F67C3 (weight 12.89 kg instead of 16.06 kg).
