Odour control savings not to be sniffed at
Instrumentation specialist Analytical Technology says it has developed a hydrogen sulphide monitor
that, for the first time,
enables the measurement of levels of H2S in difficult applications, while offering savings for monitoring systems of up to 90%.
With odour control changing from an afterthought to a primary design consideration for wastewater treatment plants (WwTPs), the company says its innovative odour monitoring system offers a continuous, accurate and reliable approach to on-line H2S monitoring in wet conditions at an affordable cost. The Q45S monitor for scrubbers, which has an installed cost of £2k, uses a sensor designed to operate in condensing gas streams without the water vapour blinding the sensor. This can be typical of standard sulphide monitors. The
scrubbing odour control systems start from £30,000, yet some H2S monitors cost up to £20,000, which is just not viable. Historically, sewage treatment plants have often struggled to justify the expense of installing H2S monitors that can cost up to 80% of the value of smaller plants.
Michael Strahand, ATi’s European general manager, said: “For those facilities with limited budgets, our methods of monitoring sulphides cost effectively overcome the issues associated with hydrogen sulphide measurement and odour control.
ATi’s Q45S Wet Sensor can slash the cost of H2S monitoring
relatively low cost also makes it economically viable to monitor even small scrubbers. Typically, dry media, chemical and bio-
“ATi’s Q45S Wet Sensor for Scrubbers allows true control of the dosing systems and accurate monitoring of hydrogen sulphide levels, offering a complete solution to combating odour problems.”
Pulsar reaches sludge milestone
Success for ultrasonic instrumentation manufacturer Pulsar
Pulsar Process Measurement has found success for Sludge Finder, its popular sludge interface monitor, in framework agreements and sales across the globe. July saw a significant milestone with an order placed for the 750th Sludge Finder.
Worcestershire-based Pulsar is known for its non-contacting ultrasonic range of products. As sales director Keith Flint is keen to point out, “At heart, Pulsar is
Pulsar’s Sludge Finder 2 is in demand globally
a company of acoustic engineers, and the algorithms and analysis tools that
we have developed over the last fifteen years or so are now being applied across quite a wide family of products.” Sludge Finder uses a self-cleaning transducer to bounce a sonar signal from the interface layers throughout sludge settlement plant, intelligently analysing the signal to provide a profile of the sludge levels, including return activated sludge (RAS) and floc measurement from a single transducer.
Flint said, “There is no mystery to why Sludge Finder 2 has become so widely used, it’s simply because it works so reliably.”
