Acids for Municipal & Industrial Water Treatment in Namibia

Check pH before blaming the chlorine: above pH 8 — common in Namibian borehole supplies — most of your dose sits as the near-inactive hypochlorite ion. Correcting to pH 7.2–7.6 with a small acid dose can double effective disinfection without adding a gram of chlorine. It is the cheapest fix in water treatment and the most overlooked.

For membranes, follow the manufacturer’s CIP chemistry — typically citric or specific phosphoric-based cleaners we can supply; never put hydrochloric through thin-film membranes. For pipework, tanks and exchangers, inhibited HCl (acid plus Armohib) dissolves scale while sparing the steel. Rinse to neutral and verify before return to service.

Bunded storage out of the sun, dedicated decanting PPE (face shield, gauntlets, apron), an emergency water source, and the one unbreakable rule painted on the wall: acid into water, never the reverse. We supply acids in 25 L polycans a two-person team can handle safely, plus SDS and a one-page handling sheet for the operator board.

Scale it to the job: the packaged Scale Remover handles kettles, urinals, small heat exchangers and dosing-line flushes at ready-to-use strength with far less handling risk. Once you are circulating volumes through plant equipment, drum HCl with inhibitor is the economical route. Many works keep both — packaged for maintenance rounds, drums for shutdowns.
