pH Booster Alkaline Liquid – 25 kg Drum | UV Water Systems Oman

Water pH control is critical at two points in any RO system: pre-treatment, where feed water pH must be maintained within the membrane manufacturer’s operating window (typically 6.5–8.5), and post-treatment, where RO permeate water at pH 5.5–6.5 must be raised to a neutral or slightly alkaline range before distribution for drinking water applications. Permeate from an RO system is naturally slightly acidic because carbon dioxide passes through the membrane while carbonate and bicarbonate ions are rejected. UV Water Systems supplies alkaline pH booster liquid in 25 kg drum quantities for both pre-treatment pH correction and post-treatment remineralisation programmes across Muscat and Oman.

How pH Correction Works

The alkaline pH booster is a sodium hydroxide (NaOH) or potassium hydroxide (KOH) based formulation with buffering agents to prevent pH overshoot. It is dosed via a chemical dosing pump into the water stream with closed-loop pH control — a pH sensor downstream of the injection point feeds back to the dosing pump controller to maintain the target setpoint. For post-treatment RO permeate, the target pH is typically 7.0–7.5 to ensure water is neither corrosive to distribution pipework nor over-alkaline for the end user. UV Water Systems engineers size the dosing pump and day tank based on your system flow rate and the pH correction required.

Key Features and Benefits

Pre-treatment pH adjustment: Raises acidic feed water pH before it contacts RO membranes, protecting membranes from low-pH feed damage and optimising antiscalant performance at the correct pH range.
Post-treatment permeate conditioning: Corrects the naturally acidic pH of RO permeate to neutral, preventing corrosion of stainless steel and copper distribution pipework in Oman’s commercial water systems.
Controlled dosing: Liquid form integrates directly with automated pH control systems using standard dosing pumps — no manual mixing or batch preparation required during steady-state operation.
Improves water palatability: Slightly alkaline water (pH 7.0–7.5) is preferred by most consumers. Correcting RO permeate pH improves taste acceptability for drinking water applications.
Versatile application: Used in RO pre-treatment for membranes, post-treatment for drinking water, and wastewater neutralisation before discharge — one chemical for multiple process steps.

Applications Across Oman

pH boosters are used in Oman’s industrial RO systems treating acidic well water from limestone formations, in commercial drinking water systems where RO permeate pH must meet Oman Ministry of Health standards, and in wastewater treatment plants where effluent pH must be neutralised before discharge to Oman’s municipal sewer network.

Frequently Asked Questions

What is the target pH for RO permeate used as drinking water in Oman? Oman’s drinking water standards (OS 8/2: Drinking Water Standard) specify a pH of 6.5–8.5 for potable water. UV Water Systems recommends targeting pH 7.0–7.5 for RO permeate distributed for drinking, providing a stable neutral range with a margin on both limits.

Can I use caustic soda (NaOH) flakes instead of liquid pH booster? NaOH flakes must be dissolved in water before dosing, which requires additional preparation steps and creates an exothermic dissolution hazard. UV Water Systems recommends pre-diluted liquid pH booster for dosing systems to eliminate preparation risk and ensure consistent concentration.
