With their increasing use, nanoparticles will become concentrated in urban effluents in the future. Both adequate monitoring methods and water treatment technologies will be necessary to assess and avoid consumer exposure. This paper reports results in these two challenging areas for both organic and inorganic nanoparticles. Treatment experiments indicate that lamellar settling is better adapted ...
Odors are very distinct air contaminants as they generate nuisances (see note at the end). The factors playing a role in the determination of odor annoyance are : odor concentration and intensity, frequency, appreciation, duration, synergy and location. Chromatotec proposes an automated solution to well identify the origin and the level of odors. Technology Description We offer a ...
The wireless vibration network of Wi-care system consists of the communication between three components; the transmitter, the range extender and the receiver. The transmitter is fixed on the machine and transmits the vibration and the temperature data at the measurement point. The second element of the Wi-care wireless network is the range extender, its function is to transmit vibration and ...
Phragmites australis for sludge dewatering and stabilization processes have been widely proved. The presence of reeds, indeed, efficiently allows solids dewatering and organic matter stabilization in order to obtain a stabilised product that can be suitable for land application, even if its environmental impact has to be considered. The actual revision of the European Union's Working Document on ...
Clean drinking water is an essential need of mankind. Often surface water like rivers or lakes is used as drinking water source. To prevent these resources from pollution the effective treatment of waste water is a must. For example in China 75% of discharged waste water is coming from pulp and paper, textile and dyeing industries. To run a waste water treatment plant in the most efficient way ...
A 4-month sampling campaign has been conducted for the monitoring of three drinking water treatment plants using flow cytometry and culture-based methods to provide information related to changes in bacterial concentration according to treatments. Flow cytometry is a fast and user-friendly technique enabling bacteria quantification and viability assessment in less than 1 hour. Specific profiles ...
A pilot-scale plant was employed to validate the performance of a proposed full-scale advanced water treatment plant (AWTP) in Sydney, Australia. The primary aim of this study was to develop a chemical monitoring program that can demonstrate proper plant operation resulting in the removal of priority chemical constituents in the product water. The feed water quality to the pilot plant was ...
Equipment, Context: Surface aerator:Vertical equipment, gearbox associated very high cost for wired solution, aggressive environment, very few visual and periodical inspections. Centrifugal pump: Located underground in concrete basement, busy area, pipes and metal structure all around. Effluent pump: Vertical equipment, ...
Due to the increasing number of requests for the monitoring of waste water treatment plant atmosphere, Chromatotec® has designed a specific analytical solution for sulfur and nitrogen compounds analysis. For more than 25 years, Chromatotec® has proven its value and expertise in measuring and recording sulfur concentrations in waste water treatment plant. Chromatotec® has completed its ...
Southern Water operates 370 wastewater treatment plants (WWTP), many of which are unmanned for most of the time and most have numeric environmental permits, so a network of online monitors has been established to improve treatment and protect discharge compliance. This has involved the installation of final effluent monitors at over 300 sites in a programme that has lasted for more than ten ...
Drinking water treatment in North America has stringent requirements for effluent water quality, with a great amount of attention being drawn to the presence of hazardous disinfection by-products (DBPs) persisting through water distribution systems. The operation of water treatment plants involves addition of various mixing agents to help with coagulation and settling of organics in the raw water ...
Globally, little attention is paid to gaseous emissions from wastewater treatment processes. This contrasts greatly with the regulatory monitoring that is applied to the quality of water emissions from such facilities. However, in Helsinki, Finland, a large municipal wastewater treatment facility continuously monitors its emissions of greenhouse gases (GHGs) to help in the city’s efforts to ...
Six SmartScan50 were connected via a RS485 ModBus network in order to monitor the level in hospital water treatment tanks. The Challenges The customer needed to measure the level and determine when to fill or to empty each tank after or during the treatment. Light foam was present A communication network was required Before choosing SolidAT’s ...
Rand Water is one of the largest waterworks worldwide with a capacity of 4,8 Mio m³ per day for the water supply of 10 millions of people in a radius of 18.000 km2. The two principal works are situated in the industrial centre of South Africa. 8 different Grundfos Alldos chlorine stations with a capacity of up to 120 kg disinfect the water using chlorine gas. More than 100 dosing pumps provide ...
We can help improve health and safety and increase energy reduction. At the moment you probably keep water temperatures above 60°C and you probably undertake regular chemical or thermal water system treatments and shower head treatments, all to prevent the growth of Legionella in your water system. There are several reasons to do this including legal, safety, ...
Customer: Rainbow Group and T95C Application: Portable water sampling Background: Established in 1985, Rainbow Group are environmental demolition and civil engineering contractors based in Padstow, NSW. Their services include construction, excavation, demolition, remediation and water treatment. Rainbow Group has a renowned ...
The biological treatment of drinking water is undertaken using both organic and inorganic contaminants, and can be used to treat groundwater and surface water. These contaminants, contrary to what the name implies, are applied to strip away the factors that make the water unsafe for drinking until it is potable—meaning drinkable. If you would like to learn more about the benefits of ...
Experimental measurements conducted in the laboratory, involving hyperspectral analysis of water samples taken from public water resources, have motivated a re-evaluation of issues concerning the potential application of this type of analysis for water monitoring, treatment and evaluation prior to filtration. One issue concerns hyperspectral monitoring of contaminants with respect to types and ...
Industrial Wastewater Treatment Batch Treatment Systems (BTS) are intended for lower daily volumes of wastewater typically less than 10,000 gallons per day and designed to “batch” treat wastewater from start to finish at one time. In a batch treatment system, a volume of wastewater is gathered, treated by chemical / physical / biological means, and discharged. Storage ...
Lake Edku, one of the northern Nile Delta Lakes, subjected to huge inputs of nutrients (especially phosphorous and nitrogen). These nutritional conditions create rich resource spectrum for algal growth and make the lake suffer from high level of eutrophication. Lake Edku does not have numeric water quality criteria for nutrients. The main objective of this research is to develop a model which can ...
