3072/F75Q1 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 3072/F75Q1: 30×72″ housing, automatic Runxin F75Q1 valve, up to 10.0 m³/h, 2" connection, top mounting. The valve is designed for filtration — reagent-free backwash of the load. Weight 91.2 kg.

Configuration within the line: vessel size 3072 (30×72″) with control valve Runxin F75Q1. On the same vessel size 3072 (30×72″) the line also offers Runxin F75A1 and Runxin F77B1. The same control valve Runxin F75Q1 is fitted on 1465, 1665, 1865, 2472 and others.

On vessel size 3072 the closest alternatives to Runxin F75Q1 are Runxin F75A1 (weight 91.7 kg instead of 91.2 kg) and Runxin F77B1 (valve capacity up to 18.0 m³/h instead of up to 10.0 m³/h, weight 97.7 kg instead of 91.2 kg).
