pH
pH affects chlorine disinfection chemistry and the water environment. A dedicated pH channel supports controlled correction. Select a sensor and sample arrangement that operators can inspect, clean and calibrate.

Commercial swimming pool water treatment
Changing demand needs a controlled response.
Bather load, sunlight, make-up water and operating schedules change a pool’s treatment demand. A fixed chemical feed setting may not follow those changes. Delayed adjustments can leave operators correcting swings instead of maintaining a stable process.
A commercial pool dosing system connects representative measurements to metering pumps. Automatic control supports consistent operation, but still needs independent water tests, sensor maintenance and clear operator procedures.
Where the system fits
Hotels and resorts need visibility across guest pools with different schedules. Water parks may have multiple independent circuits and rapidly changing loads. Clubs and schools need controls aligned with supervised operating hours.
For other commercial pools, identify each separate circulation circuit before selecting shared or dedicated monitoring. One reading should not be assumed to represent pools with different water conditions.
Automatic chlorine dosing system
Measure. Compare. Dose. Verify.
A feedback loop links the measured water condition to a controlled chemical response.

- Pool Circulation
A sampling panel delivers water to the sensors under suitable flow conditions. The controller compares valid measurements with agreed setpoints and sends dosing commands to compatible pumps. Chemicals travel from separate tanks through their pumps to the designed injection points.
Water then circulates and mixes before the effect is measured again. Sampling delay and mixing time matter: excessive dosing before a representative response returns can cause overshoot. Loss of circulation, loss of sample flow or an instrument fault should trigger the agreed inhibition and alarm logic.
Choose the measurement deliberately
pH, ORP, free chlorine & temperature
ORP
A pool pH ORP controller can track oxidation-reduction conditions alongside pH. ORP is measured in millivolts, not chlorine concentration. Its relationship to chlorine changes with water chemistry; there is no universal conversion to a free chlorine reading.
Free chlorine & temperature
Direct free chlorine measurement supports residual-based control where specified. Temperature provides operating context and compensation where supported by the selected instrument. Confirm measurement range, sample conditions and verification method before selection.
System components
Select equipment as a connected system.
APURE instruments, HAOSH metering pumps and KUOSI dosing equipment can form part of an application-selected arrangement.
Sampling & instruments
Provide representative sampling, suitable flow regulation and access for sensor maintenance. Confirm instrument inputs and the flow conditions required for reliable readings.
Controller & safeguards
Match outputs to pump inputs. Define dosing limits, delays, high/low alarms and permissives. Agree how operators acknowledge faults and return the system to service.
Pumps, tanks & injection
Review chemical compatibility, discharge pressure, suction conditions and tank level signals. Keep incompatible chemicals separated and have injection spacing, backflow protection and containment designed for the installation.
Optional remote monitoring can expose readings and alarms to the facility team. Confirm supported protocols and network access before specifying BMS integration. An on-site sodium hypochlorite generator can also be evaluated as the disinfectant supply source.
System sizing parameters
What We Need to Select Your System
Send values for each circulation circuit, with drawings or equipment photos where available. Include units with chlorine targets and identify the chemical concentration. Unknown values can be marked for review.
Pool volume alone cannot determine a pump size. Selection also considers peak demand, injection pressure, chemical strength, operating hours and the pump’s controllable dosing range.

Dubai project planning
Coordinate dosing with the pool approval process.
Automatic chemical feeding is one part of the overall pool design. The contractor should coordinate circulation, monitoring, chemical handling and equipment documentation with the project consultant.
Read the Dubai commercial pool dosing requirements guide ↗ Equipment example / project planning
A cabinet, pumps and separate tanks.
The supplied photograph shows a physical dosing arrangement. It illustrates equipment layout; the customer, location, operating measurements and project results have not been verified.
For a proposed hotel-pool retrofit, review the existing circulation line, sampling access and injection points first. Then identify which measurements, pump interfaces and interlocks can be retained and which require replacement. Confirm maintenance access before selecting the final cabinet or skid arrangement.
This is an illustrative planning example, not a completed customer case or a performance claim.
Project case documentation ↗Practical questions
Before you specify a system.
Is ORP enough to measure free chlorine?
ORP is not a direct chlorine concentration measurement. If your specification requires residual chlorine control, review a suitable chlorine instrument, sample conditions and an independent verification method alongside pH.
What determines the dosing pump size?
Required chemical delivery at operating pressure, chemical concentration, peak treatment demand and the controllable dosing range all matter. Pool volume alone is insufficient; circulation flow and the operating profile are also reviewed.
What information is needed to propose a pool dosing system?
Share the pool type, approximate volume, number of pools, circulation arrangement and current dosing method. Existing equipment photos, water quality information and control requirements help with selection.
Can you support pool contractors and MEP companies?
Yes. Our scope includes equipment supply, system selection, technical support and project coordination for contractors, facility managers and system integrators.
Can automatic dosing be added to an existing pool?
An upgrade may be possible after reviewing circulation, sampling, dosing points, existing controls and site conditions. Compatibility is confirmed before proposing equipment.
Do you provide local installation in Dubai?
Our stated scope is equipment supply and technical or project coordination. Installation responsibilities and any local project partners must be agreed separately.
Can the solution include a sodium hypochlorite generator?
Yes, on-site generation can be considered as an optional part of the disinfection arrangement, subject to treatment demand, available utilities and site requirements.
Start with your pool
Request a pool dosing solution.
Share your pool parameters, current treatment method and the issue you want to solve. We will review equipment selection and interfaces before proposing the supply scope.
For an existing site, photographs of the control panel, pump nameplates and circulation layout help identify integration questions. Installation and commissioning responsibilities are agreed with your project team.

Automatic chlorine control
A residual-based channel compares a valid free chlorine measurement with the agreed operating target and adjusts a compatible metering pump. If ORP is selected as the control input, document the site-specific control basis instead of treating millivolts as chlorine concentration. Define maximum feed limits, sampling delay and loss-of-flow inhibition.
Review pump delivery at the injection pressure, its controllable range and chemical compatibility. A pump sized only for the highest possible demand may be difficult to regulate during quiet periods.
Automatic pH control
A separate pH channel evaluates its own sensor and correction requirement. The selected chemical, materials, injection arrangement and controller action must match the engineering design. Coordinate pH correction and disinfectant dosing without allowing incompatible chemicals to mix in storage or feed lines.
Confirm stable sample flow, sensor calibration and representative mixing before tuning the loop. Read the ORP versus free chlorine guide for the role of pH in interpreting monitoring data.
Selection tool
Estimate your rectangular pool volume
Volume = length × width × average water depth. Use water dimensions in metres. For slopes, steps, irregular shapes or separate balance tanks, provide drawings for a more accurate assessment.
This estimates water volume only. It does not calculate chemical dosage or select a dosing pump. Circulation flow and treatment demand must be reviewed separately.
