The pH measurement plays a vital role in the industrial process irrespective of the type of industry. The pH value is an important attribute that has major effect on the quality of product being produced. The pH value ranges between 1to14, in which 7 indicates neutral, pH more than 7 indicates basic, and pH less than 7 indicates the acidic solution. It can be measured using a pH meter which is made up of three components, such as an internal electrode, a reference and a high input impedance meter. This is used generally by Water Treatment Plant Managers, Scientists and Researchers.

pH decides whether the water is consumable or not. There is a need to keep pH levels at some level so that humans can consume directly or indirectly.pH is also controlled in some chemical processes for proper reactions to occur & avoid plant corrosion. How are various industries using a pH meter attain product quality in their production process?

Wastewater & Effluent treatment Industry

In wastewater & effluent treatment, hazardous substances, organic waste, and heavy metal compounds are removed from the water with the help of chemicals added to adjust the pH level of the water and separating the dissolved waste from the liquid. The waste discharge should be monitored for pH level to avoid unnecessary environmental issues when dumped into the environment. During the step-by-step wastewater treatment process, the pH level should be monitored between each phase of the process to ensure safe water at the end. The pH meter is an important instrument in this industry to ensure the quality of treated wastewater.

 Aquaculture Industry

Aquaculture is the fastest growing with a multibillion-dollar business in the food animal industry which is responsible for supplying seafood to half of the world. The industry is yet to overcome some technological challenges. In order to keep aquatic creatures alive companies need to monitor the pH level changes on a regular interval to ensure they are healthy enough to be consumed. The safest best range of pH levels for fish to grow is between 6.5 and 9.0. Thus the pH meter used to monitor the acidity or alkalinity of water storage facilities ,like ponds , in which fishes are grown & control the same.pH is an important consideration in aquaculture industry.

 Food and Beverage Industry

The food & beverage industry deals with water more than any other industry as water is basic ingredient and used in all phases of food processing. Thus pH level plays an important role in maintaining the quality, taste, and safety of the products produced. Meters that measure pH level are used to insure that food products have an adequate acidity level that will prevent growth of food borne pathogens. To assure both consumer safety and product quality, beverages in particular use a final pH measurement at the bottling machine to confirm that the product is safe for consumption.

Pool and spa water Industry

In the swimming pool(especially community pools), there is a necessity to measure the pH level in order to determine how much sterilizing agents are needed to put in water to maintain a safe swimming environment. Sometimes water gets cloudier, it is due to pH levels being too high swimmers can get skin and eye irritation. The safest pH level for the pool or spa is between 7.2 and 7.8. Measuring and controlling Ph makes the Swimming Pools and Spa’s user friendly and safe !

Agricultural Industry

pH in Soil

In agriculture, soil pH plays an important role in the development of crops including root development, microbial activity, nitrogen fixation influenced by the balance of acid-forming nutrients and alkaline-forming nutrients. So it is important to monitor the pH level of the soil.

pH in Hydroponics

Hydroponics is the process of growing plants in a nutrient-enriched water-based solution instead of soil. The plant will die quickly when the pH level of the water swings too much in one direction. To avoid this kind of issue specialists monitor the pH level continuously with the use of a pH meter.
