Pulsemate Exercise

Scenario: A water treatment plant needs to adjust the pH level of incoming water from 6.5 to 7.2. The plant uses a Pulsemate metering pump to inject a base solution (sodium hydroxide) into the water stream.

Task:

  1. Describe how the Pulsemate pump contributes to achieving the desired pH adjustment.
  2. Identify at least three factors that could influence the flow rate of the base solution needed from the Pulsemate pump.

Exercice Correction

**1. How Pulsemate pump contributes to pH adjustment:** The Pulsemate metering pump delivers a precise and controlled amount of sodium hydroxide solution into the water stream. This precise dosing allows for gradual and accurate adjustment of the pH level, ensuring it reaches the desired target of 7.2. The pump's adjustable stroke length allows for fine-tuning the flow rate of the base solution to achieve the desired pH change. **2. Factors influencing base solution flow rate:** * **Incoming water pH:** The larger the difference between the incoming water pH (6.5) and the target pH (7.2), the higher the flow rate of the base solution needed. * **Water flow rate:** A higher water flow rate will require a higher flow rate of base solution to maintain the desired pH. * **Concentration of the base solution:** A more concentrated base solution will require a lower flow rate to achieve the same pH change.
