The Strathtox provides precision respirometry to rapidly measure actual Activated Sludge bacterial performance.

• Advanced 6-cell precision OUR measurement system
• Easy and rapid test procedures
• User friendly software providing a real time display of bacterial respiration
• Automatic Report generation and calculation of EC10,20,50 values for carbonaceous and nitrifying bacteria
• Efficient procedures gives test times of between approximately 10 and 30 minutes
• Tests provided are: Carbonaceous and Nitrifying Sludge Health, Critical Oxygen Point Analysis, Respiration Inhibition, Nitrification Inhibition, BOD(ST), and Respirometry.T

Applications in: 

• Toxicity Management
• Nitrification Management
• Aeration Efficiency
• Nutrient Control
• Sludge HealthS
• System Trouble-shooting
• Short-term BOD
• Plant capacity
• Respiration tests

Strathtox is an integrated desktop respirometer comprising the following sub-systems:

• Temperature controlled Circulating Waterbath This is used to maintain the activated sludge at constant temperature during a respirometry run. A six position magnetic stirrer is located beneath the bath. The six 20ml respirometer cells are located in a rack, for easy removal at the end of a run. 
• Activated Sludge Temperature Controlled Containment A flask provides aeration and containment of approximately 600ml of AS that can also be spilt for Nitrification testing.
• Oxygen Electrodes These high precision electrodes are housed in electrode holders for easy insertion into the respirometer cells. They require little maintenance, other than occasional membrane changes.
• Oxygen Interface The six oxygen electrodes are connected to this unit, which transmits the digital signals to the computer software.

Software

• The easy-to-use Windows software comprises 5 different tests. Each test program has a similar basic structure compromising four stages: Setup; Recording; Analysis; Report. To illustrate this, sample screens from a Respiration Inhibition Test are shown below. 
• Setup - This is the first screen and is used to input the data about the test. This information is transferred to the final Report.
• Recording - Clicking a 'Start' button on the toolbar of the Setup screen, commences the recording. Six traces scroll across the screen, providing a visual check on the rate and linearity of the decline in the oxygen content of the cells as respiration proceeds. At the end of the run, a file is created to save the data.
• Report - The report window provides information on the respiration rates, inhibition or (Toxicity) values, an inhibition v concentration graph and a respiration v concentration plot, together with a full audit trail. The report is in the form of a locked spreadsheet, so data cannot be altered. The data can however, be exported to Excel, or a database for further processing, if required. The report and associated Analysis screen can be printed or saved to an archive folder.
