pH Neutralization Dosing System

Description

046 | UV Water Systems Oman

Maintaining correct pH is critical in RO systems (feed water pH 6.5–7.5 protects membranes), boiler feed water (pH 8.5–9.5 prevents corrosion), and industrial effluent before discharge (Oman environmental standards require pH 6–9). The dual-pump pH neutralisation dosing system from UV Water Systems Muscat provides automatic, closed-loop pH control — dosing acid or alkali as required to maintain the set-point pH, with automatic switching between the two pumps depending on whether the stream needs pH up or pH down correction.

Why This Matters for Oman Water Quality

Manual pH adjustment — adding acid or alkali periodically and measuring pH with a handheld meter — is labour-intensive and produces large pH swings. Automatic pH dosing systems use an inline pH electrode connected to a controller that activates the appropriate dosing pump (acid or alkali) in proportion to the pH deviation from the set-point. UV Water Systems designs these systems for Oman’s RO pre-treatment (where pH must be held in range for optimal membrane rejection and antiscalant effectiveness) and industrial effluent neutralisation before discharge.

Applications in Muscat & Oman

RO system feed pH correction in Oman (where feed pH is outside the 6.5–7.5 optimum), industrial effluent neutralisation before discharge, boiler condensate pH correction, swimming pool pH control, and any Oman water treatment application requiring closed-loop automatic pH management.

Frequently Asked Questions

What chemicals are used for pH adjustment? For pH reduction (acid dosing): hydrochloric acid (HCl) or sulphuric acid (H₂SO₄) are most common in Oman water treatment. For pH increase (alkali dosing): sodium hydroxide (NaOH) or sodium carbonate (Na₂CO₃). UV Water Systems advises on the safest and most economical chemical for your specific application and recommends appropriate safety equipment for chemical handling.

Does UV Water Systems supply pH calibration buffers and electrode maintenance chemicals? Yes — UV Water Systems supplies pH calibration buffer solutions (pH 4, 7, and 10 standard), electrode cleaning solution, and electrode storage solution for all pH dosing systems in Oman. Regular electrode calibration (monthly minimum) is essential for dosing accuracy. Our AMC service includes pH electrode calibration at each scheduled maintenance visit.
