  • Do you need sensors for sewage and slurry outflow monitoring?

    The CTG UviLux Effluent fluorimeter enables in-situ real-time reporting of levels of sewage and BOD within both natural water systems and water processing plants. By use of UV fluorescence, the UviLux Sewage Monitor detects protein which is inherent within sewage and slurry and provides a means of assessing concentrations of sewage and slurry in solution with unparalleled accuracy and resolution. The principle behind the measurement is based on fluorescence excitation of Tryptophan-like fluorescence, within the UV wavelength band. Use of such fluorescence provides signal detection far superior to absorption methods currently in use. Studies have shown that use of such fluorescence provides robust and repeatable measurements of sewage and slurry solutions, and correlates with both BOD and Bacterial Contamination.

CTG Algae Monitoring System for United Utilities

1 cathyBushyParkUnited Utilities has chosen the Chelsea Technologies Group (CTG) ALGAE-Wader Pro and ALGAE-Station Pro systems to assist them in real time assessment of algae levels in their water sources feeding into a number of their Water Treatment Works. 

The CTG Algae monitoring systems were chosen after an extended trial period which successfully demonstrated the use of the TriLux fluorometer, from which these systems are based, in detecting chl-a, Phycocyanin and Phycoerythrin levels.

The CTG ALGAE-Wader Pro is a portable system which includes the Hawk handheld display and logger.  The Hawk provides simple and robust interaction with the field operator, displays all data in either numerical or graphical form, provides RAG thresholds and logs all data with both time and position stamps.

The CTG ALGAE-Station Pro is a robust wall mounted system which includes the Watchkeeper display and logger.  The Watchkeeper displays and logs all data, provides Alarm thresholds and outputs 4-20 mA for connection to SCADA type networks.

CTG Sea Sentry Exhaust Gas Scrubber Water Monitoring System has achieved DNV GL Statement of Compliance

Sea Sentry on shipWe are pleased to announce that our Sea Sentry Exhaust Gas Scrubber Water Monitoring System has achieved DNV GL Statement of Compliance for MEPC.259(68). Vigilant testing by DNV GL ensured that Sea Sentry met the requirements for calibration range, drift, accuracy, precision and noise; as well as satisfactorily mitigating for the influence of turbidity, UV absorbance, temperature and salinity. The effectiveness of Sea Sentry’s de-bubbler and the use of the test kit supplied to validate the optical sensors was also demonstrated to meet the requirements of DNV GL.

“We would like to give special thanks to our technical team for the hard work invested in developing such a refined system,” said CTG’s Maritime Sales Manager, Stephanie Lavelle. “We are extremely pleased to be successfully installing our systems on vessels around the world, so that ship owners can confidently monitor the efficacy of their scrubber systems and ensure they operate within regulations.”

CTG to present work on the “Application of portable in situ UV fluorescence sensors in natural & engineered aquatic systems” at next week’s European Geosciences Union Conference in Vienna

BethanyFoxCTG represented by Bethany Fox (shown left), will present a poster at the European Geosciences Union (EGU) Annual Conference in Vienna on April 19th.

It is a great honour to be invited to present work in a session titled ‘Natural organic matter in aquatic systems: methods, fractions and interactions in natural and engineered systems’ as this is the first time the session has specifically invited contributions from industry to this traditionally academic conference, enforcing how the work undertaken is at the forefront of both academia and industrial development.

A poster of the recent R&D efforts surrounding the use of CTG’s UviLux fluorometers will be presented in the ‘Sensor technology for NOM measurements’ section of the conference session.

FastBallast generated lots of interest at 3rd Ballast Water Management Summit today in Long Beach

Ballast Water Conference Stephanie LavelleCTG’s new Maritime Sales Manager, Stephanie Lavelle demonstrating the FastBallast Compliance Monitor at the 3rd Ballast Water Management Summit in Long Beach today showing just how quick and easy it to monitor ballast water at the levels required by the IMO D2 standard.

Why is the FastBallast Compliance Monitor causing so much excitement?

advert image_Rev

FastBallast is unique in that it can operate in both flow-through and static modes. Assessing treated water discharge in flow-through mode allows the user to gain a more representative sample, by analyzing a larger volume of water. Static sampling mode allows for an instantaneous result from a single sample allowing the user to make rapid assessment of compliance.

The FastBallast Compliance Monitor goes on display at 3rd Ballast Water Management Summit, Long Beach, USA, from tomorrow. Read more http://goo.gl/h4JVf7
