The characteristics of the pH regulator.

What are the characteristics of a pool pH regulator?

Water can be too basic or too acidic because the pH fluctuates depending on multiple environmental factors. In this case, water quality deteriorates, and pool equipment can be degraded. That's why it is necessary to frequently check the pH level either manually or with a pool pH regulator. The latter allows maintaining an optimal level for the proper functioning of the pool. It is an automated device that manages the ideal pH level automatically and regularly on your behalf.

What are the peculiarities of a pH regulator?

The pH regulator is a device with a relatively simple design, consisting of a casing, a probe, a regulator, and a dosing pump. However, each machine has its own characteristics, especially regarding the regulation mode or the dosing pump.

Dosing Regulation

Several types of dosing are possible for pH regulators. The pool filtration pump must operate for the regulator to perform measurements and inject the corrective product. The filtration time should be sufficient and proportional to the water temperature.

• Manual dosing dispenses the corrective product over a given time.
• Predictive or cyclic dosing is calculated based on the pool's water volume.
• Proportional dosing injects pH, taking into account the measurement taken in the pool and the setpoint. It adjusts and doses according to the difference between the observed value and the target value. The regulator increases or decreases the injection frequency based on deviations.
• Sequential dosing is a proportional dosing that considers the pool's volume and the regular diffusion of the product.

Proportional and sequential dosing are the most efficient.

The Dosing Pump

The peristaltic pump consists of a rotor with a certain number of rollers and a flexible tube. It draws the liquid pH from the bottle and injects it into the pipeline towards the pool. When the rollers rotate in the rotor, they compress the tube at 2 points, allowing a certain amount of fluid to move.
The peristaltic pump can operate at various speeds, even continuously.
It is ideal for family pools.
Maintenance is simple, and the only wear part is the tube, which loses its elasticity over time.

The electromagnetic pump consists of a set: solenoid electromagnets and springs, a membrane, and two check valves.
Electrical impulses activate and deactivate the solenoid. When the solenoid is activated, an electromagnet moves the magnetic axis and pushes the membrane. When the solenoid is deactivated, springs return the membrane to its place. The back-and-forth movement of the membrane moves the pH in the transparent tube. Check valves prevent the liquid from flowing back. The dosage is determined by programming.
The regulation can be managed by a solenoid valve; there is no dosing pump, and the solenoid valve injects the pH. Failures are thus largely avoided. The dosage is created by a venturi effect and is adjusted with a dial. This system is not or very rarely used in the pool industry.

The Casing

The casing is a body that protects the mechanism and contains an indispensable microprocessor for the device's programming and operation.
Programming can be automatic, semi-automatic, or manual and is done through a keyboard, buttons, or a potentiometer.
The pH value at a specific moment can be read through an analog or LCD screen.
Various visual and/or audible alarms can be integrated: low liquid level in the can, pH level outside the recorded values, overdosing, too low pump flow, etc.

The pH regulator for pools is a reliable and robust tool that frees you from pH control constraints. However, don't forget to change the corrective product canister!
