The Boltac Jar Stirrer

Introduction

The Boltac Coagulation & Flocculation Simulator is a device used to simulate the process by which water is cleaned. The addition of both primary and secondary coagulants and coagulant aids can be simulated in this machine (otherwise known as a Jar Stirrer or Jar Tester, or alternatively as a Floc Tester). Knowing how to relate the results of a jar test back to the plant operation is the key to success.

The process being simulated is normally taking place in a vast settling tank, in which up to five million litres can be in process at one time. Once proficient, an operator can gain accurate results using 4 or 6 litres per test. Depending on the design of the process being simulated, the jar test can show results in as little as 30 minutes, compared to up to a number of hours when monitoring the actual process.

If a change is to be made without first ascertaining the amount or direction of the change, costly, (sometimes dangerous), and embarrassing errors can be made. The practised and frequent use of the machine can lead to chemical savings, adherence to performance criteria, and a definite aid to Quality Assurance auditing.

This machine is designed to give many years service, and will do so, given the proper care. We enjoy receiving feedback re our equipment, good we take with pride, and we like to call constructive criticism, please feel free to offer yours
