4872/F96B1 reagent-free filtration unit

The industrial-size reagent-free filtration unit removes dissolved iron, manganese and hydrogen sulfide from water, along with turbidity and color. The housing is made of fiberglass with an internal polyethylene lining; inside are granular filter media, a supporting gravel layer and a drainage-distribution system, and on the outside is an automatic control valve.

Oxidation takes place on the media itself: iron, manganese and hydrogen sulfide convert to an insoluble form, are retained in the bed and flushed to drain during backwash, so no reagents are required. Housings from 24 inches are fitted with larger Runxin valves with 2″ and 3″ connections and capacity from 10 to 50 m³/h; some models are side-mounted, tapped into the housing wall. Backwashing such a filter requires a corresponding water reserve and drain throughput.

Design 4872/F96B1: 48×72″ housing, automatic Runxin F96B1 side-mount valve, up to 50 m³/h, 3" connection, side mounting. The valve is designed for filtration — reagent-free backwash of the load. Weight 233.3 kg.

By weight it sits between 4872/F112B1 (226.3 kg) and 6367/F112B1 (376.3 kg): 233.3 kg. Valve capacity up to 50 m³/h — the same as on 6386/F96B1 and 6367/F96B1.

One step down by weight — 4872/F112B1: control valve Runxin F112B1, automatic instead of Runxin F96B1, automatic. One step up — 6367/F112B1: vessel size 6367 (63×67″) instead of 4872 (48×72″), control valve Runxin F112B1, automatic instead of Runxin F96B1, automatic.
