Applications of pH Controller in Kolkata | ph Controller Manufacturers in Kolkata

Water Treatment Plants

pH controllers are used in water treatment plants to control acidic and alkaline conditions. The controller can operate dosing pumps to maintain the required pH value.

ETP and STP Plants

Effluent treatment plants and sewage treatment plants require pH control before discharge. A digital pH controller helps maintain process quality and supports better neutralisation control.

RO Plants

In RO plants, pH control is important for feed water conditioning and chemical dosing. Online pH controllers help maintain stable process conditions.

Chemical Dosing Systems

Digital pH controllers are used in chemical dosing systems where acid or alkali dosing is required automatically according to the measured pH value.

Leather and Tannery Industries

Kolkata and nearby industrial areas have leather and tannery applications where pH control is important for process water, chemical treatment and effluent treatment.

Textile and Dyeing Industries

Textile processing and dyeing units use pH controllers for dye bath control, washing process, chemical treatment and ETP applications.

Pharmaceutical and Chemical Industries

Pharma and chemical industries require pH monitoring and control for process liquids, utility water, dosing systems and wastewater treatment.

Food, Dairy and Beverage Plants

Food, dairy and beverage plants use pH monitoring and control for process consistency, water treatment and quality management.

Calibration Process for pH Controller

Calibration with 7 pH Buffer Solution

1. Clean the pH electrode with clean water.
2. Dip the electrode in standard 7 pH buffer solution.
3. Wait until the reading becomes stable.
4. Rotate the 7 pH calibration screw slowly.
5. Set the display value to 7.00 pH.

Calibration with 4 pH Buffer Solution

1. Wash the electrode again with clean water.
2. Dip the electrode in standard 4 pH buffer solution.
3. Wait until the display reading becomes stable.
4. Rotate the 4 pH calibration screw slowly.
5. Set the display value to 4.00 pH.

For accurate pH control, always use fresh buffer solution and clean the pH electrode before calibration. Do not rub the glass bulb harshly because it can damage the sensitive surface of the electrode.

Work Instructions and User Precautions

• Install the pH controller in a clean and dry electrical panel.
• Use a suitable pH electrode according to the process liquid.
• Do not keep the pH electrode dry for a long time.
• Clean the electrode regularly in dirty water, chemical solution or effluent.
• Keep pH signal cable away from high voltage wiring, VFD cable and motor cables.
• Use standard 4 pH and 7 pH buffer solution for calibration.
• Use relay output through contactor or interposing relay for higher pump load.
• Protect the controller from water splash, acid fumes and high humidity.
• Replace the electrode if readings become slow, unstable or incorrect.
