UV Water Systems Oman

Closed-loop chemical dosing — where a sensor measures the actual water parameter (pH or ORP) and the controller adjusts the dosing pump output to maintain the set-point — requires a reliable, accurate controller. The Emec ORP/pH controller (panel-mount) from UV Water Systems Muscat provides exactly this: a wall or panel-mounted controller that reads an inline pH or ORP electrode, compares the reading to the operator-set target, and energises the appropriate dosing pump relay to correct any deviation.

Why This Matters for Oman Water Quality

ORP (oxidation-reduction potential) is the primary control parameter for chlorine disinfection — rather than measuring chlorine concentration directly, ORP measures the oxidising power of the water, which correlates closely to the free chlorine residual effective for bacterial kill. At ORP values above +650 mV (measured vs Ag/AgCl reference), bacterial disinfection is reliably achieved in Oman’s treated water distribution. The Emec ORP controller automates this: the chlorine dosing pump runs until ORP reaches the set-point, then stops — preventing both under-dosing (biological risk) and over-dosing (chemical waste and taste complaints).

Applications in Muscat & Oman

Frequently Asked Questions

What is the difference between pH control and ORP control? pH measures hydrogen ion concentration — controlling acid or alkali dose to maintain a target pH value. ORP measures the oxidising/reducing power of the water — controlling chlorine or other oxidant dose to maintain effective disinfection. UV Water Systems uses pH controllers for acid/alkali dosing on RO pre-treatment and ORP controllers for chlorine disinfection on Oman water supply and cooling tower systems.

Is calibration of the pH/ORP electrode required, and how often? Yes — pH electrodes should be calibrated monthly with standard buffer solutions (pH 4.0 and 7.0 minimum) to maintain ±0.1 pH accuracy. ORP calibration uses an ORP standard solution. UV Water Systems includes electrode calibration in all AMC visits for pH and ORP dosing systems across Muscat and Oman.
