Organic load is one of the most important parameters for discharge control of municipal and industrial wastewater. Permissible limits are guided through regulations and must be monitored accordingly. However, further opportunity to optimize plant performance exists by monitoring organic loading in upstream treatment processes. The use of on-line controls allows limit values to be adhered to, products to be saved, and plants to be protected against unforeseen events. Total Organic Carbon (T...

Non-Revenue water is more a management issue than an infrastructure and Engineering challenge in Africa. Poor management and decision are the result of 65% of total non-revenue water. While the cost of reducing non-revenue water is very little compared to the economic and political cost of loss, very little has been done to address it. Nairobi City water and Sewerage company has in the last five years been proactive in managing the loss of water related to management and decision (Referred to...

In addition to being the largest water and wastewater utility in England with nearly 1,900 DMAs, Anglian Water's drive for innovation spurred an ambitious vision for leveraging Big Data to streamline operations to better service its 6.4M customers today and for future years to come. This vision dubbed the IRIS programme is a five-year project that came to fruition in 2015 with the completion of the cornerstone project, the replacement of one of the UK's oldest telemetry systems. This system c...

Conventional biological wastewater treatment plants (WWTPs) include one or more secondary settling tanks. Their primary function is to clarify wastewater and prevent solids to exit the WWTP and enter the receiving water body. In addition, settling tanks help to thicken sludge that is returned to the biological reactors, which ultimately helps to maintain a high biomass concentration. Thickening also increases the concentration of the excess sludge, thereby reducing excess sludge treatment cos...

This work evaluates UV-Vis spectrometry as a tool to estimate nitrite in a continuously operated urine nitrification reactor. The need for such a tool originates from the sensitive urine nitrification systems which need control for stable operation. At this time, the LASSO model identification method which selects a small number of UV-vis absorbance wavelengths proves sufficient to capture the most important dynamics of the nitrite concentration. This is likely sufficient for stabilizing cont...

Some years ago it was impossible thinking about having real data about the most important parameters in rivers, lakes, the sea or the environement Nowadays, is a reality. Water and Environment markets are growing not only as independent solutions for water areas or environment projets but also for Smart Cities deployments or Smart Agriculture ones. Libelium designs and manufactures hardware for wireless sensor networks and a complete software development kit (SDK) so that system integrators,...

Jar testing is used extensively in the drinking water purification industry to simulate performance of various chemical coagulants and process conditions without altering full-scale treatment process. This testing has become even more critical in recent years due to climate changes and security threats. For many plants, optimization of treatment processes to increase removal of total organic carbon (TOC) can help reduce formation of undesirable and highly regulated disinfection by-products (t...

UV/Vis spectrophotometers have been used to monitor water quality since the early 2000s. Calibration of these devices requires sampling campaigns to elaborate relations between recorded spectra and measured concentrations. Recent sensor improvements allow recordings of a spectrum in as little as 15 seconds, making it possible to record several spectra for the same sample. Spectrum repetitions provide new opportunities to detect outliers – a task that is difficult in non-repetitive spectra r...

The emerging availably of 'Big Data' or large datasets represents a challenge for the water industry in terms of assimilating this data with the existing operational data. Existing IT systems and structures are not designed to cope with both the volume and velocity of these datasets. More importantly they do not have the data processing and analytics capabilities to process the data into a form that can readily be integrated into these IT systems and then used for real world applications and...
