  • 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.

Stephanie Lavelle will be demonstrating the CTG FastBallast Compliancy Monitor at the BWMTech Conference, 5/6 Dec, Tower Bridge Hilton, London

FastBallast Portable Ballast Water Compliance Monitor is capable of determining the phytoplankton cell density of ballast water at the IMO D2 & USCG Discharge Standards (10 to 50 um range). Its available as a portable dual function discrete & flow-through analysis system, solely as a portable discrete sampling system or as a fully integrated system for continual flow-through analysis.  slavelle@chelsea.co.uk. https://goo.gl/yXIGPT

BACTEST Ltd partners with CTG to add a test for phytoplankton to the new “Speedy Breedy SeaSure®” treated ballast water compliancy monitor.

In order to bring Speedy Breedy SeaSure® to market, BACTEST Ltd teamed up with Chelsea Technologies Group to test for Phytoplankton and with international water testing company Palintest Ltd to measure chemical contamination, meaning that SpeedyBreedy SeaSure® is a one-stop shop to determine if treated ballast water is compliant to IMO D2, VGP and other standards and the only ballast water testing solution suitable of testing for microbial, phytoplankton and chemical contamination.

“We are aa leading innovator in the field of ballast water compliancy monitoring,” said Stephanie Lavelle, CTG’s Maritime Manager. “Our portable and ultra-sensitive ballast water compliance monitor, FastBallast, is able to rapidly test phytoplankton concentrations at the D2 (10 to 50 µm) regulatory limit with the same degree of accuracy as shore based analyses. We are delighted to have partnered with BACTEST in the launch of their new Speedy Breedy SeaSure®.” https://goo.gl/wpKMoS


Speedy Breedy SeaSure® has been developed specifically as a solution to test if Ballast Water has been treated in accordance with the IMO D2, VGP and other standards. These standards set targets for ballast water treatment to reduce or completely remove certain bacteria to include E.Coli, Enterococci and Toxigenic Cholera, chemicals and phytoplankton.

CTG’s Green Ship Solutions – Interview with Stephanie Lavelle

GREEN4SEA interview highlighting our Exhaust Gas Scrubber & Ballast Water Monitoring Systems. Including an United States Coast Guard funded portable Ballast Water Compliance Device #GreenShipSolutions
We have been designing and manufacturing sensors & systems for aquatic environments for over 50 years, which includes developing maritime environmental equipment for Green Shipping Technology. With our historic expertise in fluorometers, phytoplankton and ambient environmental parameters, we have developed Sea Sentry for compliance monitoring of wash water from exhaust gas scrubber systems and FastBallast for compliance monitoring of ballast water discharge.

“Monitoring of Organics removal through Water Treatment process by use of fluorescence”

wwem2016CTG’s Senior Scientist, Dr Cathy Rushworth Curran, speaking at WWEM 2016 Seminar today on the “Monitoring of Organics removal through Water Treatment process by use of fluorescence”.

“Use of fluorescence as a method for monitoring organics within water treatment processes provides key advantages in the sensitivities that are achieved with this technique when compared with current monitoring techniques,” said Cathy. During the workshop Cathy introduced the technology, provided details of the CTG fluorescence sensors applied to these processes, and included details of monitoring of bacterial contamination within such processes.

Big congratulations to Bethany Fox – her poster won second prize in the Royal Society of Chemistry poster awards.

bfox2Big congratulations to Bethany Fox – her poster won second prize in the Royal Society of Chemistry poster awards.

Bethany Fox, PhD Student at UWE, attended the International Water Association (IWA) ‘Diffuse Pollution and Catchment Monitoring’ conference at Dublin City University, alongside CTG’s Justin Dunning, a keynote speaker at the conference. Bethany presented a poster covering her research so far, undertaken as part of the NERC CASE studentship award in association with Chelsea Technologies Group. Her poster, titled ‘Fluorescence technologies for water quality and ecosystem health monitoring’ won second prize in the Royal Society of Chemistry poster awards at this international conference. Well done Bethany!

WWEM Update: Justin Dunning will be demonstrating the CTG Wader Systems for collecting data on Algae, CDOM, Bacteria or Oil during WWEM

CTG’s Justin Dunning will be demonstrating the CTG Wader Systems for collecting data on Algae, CDOM, Bacteria or Oil on 2nd November at 3pm in the WRc demonstration area.    The CTG Wader systems have the commonality of the easy-to-use Hawk portable interface unit which allows real time display and storage of the sensor data.  Neat features include  Red, Amber Green (RAG) user set thresholds which immediately inform operators when levels are of concern.  With a built-in GPS card, all data is both time and position stamped.  The Hawk is simply connected via a USB port to the users’ PC where data can be downloaded, and any user set values such as calibration settings can be programmed in.

Sulfur Cap to Drop in 2020

The IMO’s Marine Environment Protection Committee has agreed to reduce the global sulfur emissions limit to 0.5 percent in 2020 and not wait until 2025.   “This is a landmark decision and we are very pleased that the world has bitten the bullet and is now tackling poisonous sulfuric fuel in 2020,” said Bill Hemmings of campaigner Transport & Environment.
