1344/F56E 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/F56E: 13×44″ housing, manual Runxin F56E valve, up to 2 m³/h, 3/4″ connection, top mounting. The valve is rated for filtration — backwash of the media without reagent. Weight 13.63 kg.

The smallest unit in the line by valve capacity: up to 2 m³/h against up to 4 m³/h on 0844/F67G. Weight 13.63 kg — the same as on 1044/F71Q1.

One step up by valve capacity — 0844/F67G: vessel size 0844 (8×44″) instead of 1344 (13×44″), connection 1" instead of 3/4", control valve Runxin F67G, automatic instead of Runxin F56E, manual.
