The latest precision respirometer for rapidly measuring actual Activated Sludge bacterial performance in-situ. Self Cleaning – Self Calibrating: ASP-CON can be installed permanently into several different areas in the Secondary Wastewater Treatment Plant to provide feed-forward or feed-back control for plant operation and optimisation.

Precision respirometer for rapidly measuring 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), Respirometry, Process Optimisation (Calculates Critical Dissolved Oxygen Concentrations).

Ever wished you could find out what the bacteria in your Wastewater Treatment Plant were up to right now? Well now you can, and what’s more your hand-held portable AS sampling analyser can: Show you how healthy your bacteria really are, and how this compares with the last 10 times you tested your bacteria at a particular point in your plant. Determine the respiration of your AS at your selected sampling points under prevailing load conditions.

Self Cleaning – Self Calibrating: ASP-CON can be installed permanently into several different areas in the Secondary Wastewater Treatment Plant to provide feed-forward or feed-back control for plant operation and optimisation. The ASP-Con carries out several continuous measurements, and also analyses discrete batch samples of the product to give the following parameters on a frequency which the plant operator can set.

The ASP-Con can be installed in a number of positions within the activated sludge part of the secondary treatment process, depending upon the desired control and monitoring strategy of the WWTP, be that. In the inlet or anoxic zone it can measure influent loading and act as a feed forward control sensor. In the lane itself, it can act as a very accurate controller to ensure control parameter target set points such as DO are being met correctly. If far enough down the lane you can complete SVI measures. In the outlet sections it can measure compliance performance.

Activated Sludge Plant - Suspended Volume Index: Strathkelvin Instruments Ltd are pleased to offer the ASP-SVI – an online device which will automatically complete %Settlement, MLSS and SVI testing. The test frequency can be programmed by the operator. The system is fully compatible with PLC, SCADA and DCS systems and has local alarm trending and test interrogation capability as standard. Remote access, alarm and I/O capability are also provided as optional extras.

The SI929 is a complete system for replicate measurements of dissolved oxygen, together with data recording and analysis by computer. Use of this system will result in considerable time saving in both respiration experiments and in dissolved oxygen monitoring situations. The system comprises a microprocessor-based interface which accepts up to six 1302 microcathode oxygen electrodes, and dedicated software which runs in Windows on a PC.

The model SI782 is a new concept in precision dissolved oxygen measurement. It acts as either a stand-alone oxygen meter or it can be connected to the Strathkelvin respirometry/monitoring software (supplied) on your PC. Either one or two 1302 electrodes can be connected to the meter. The digital display can be set to read in units of PO2 (torr, mm Hg, kPa) or concentration (% saturation, ppm, mg/l, or µmol/l).

The Mitocell S200 micro respirometry system comprises a 782 oxygen meter, 1302 oxygen electrode, MT200 or MT200A respirometer, together with electrode service kit, respirometry software and an easy-to-follow manual. The software includes a dedicated program for mitochondrial research that calculates State 3 and State 4 respiration rates, P/O ratios and RCR. The alternative program records and automatically calculates respiration rates and specific oxygen uptake rates.
