  • Mining Emissions Effectively Monitored with Micro Pulse LiDAR Technology

    Mining operations include blasting, excavating, scraping, and sifting large amounts of dirt. These activities create dust and other emissions that are transported by air currents to surrounding areas. It is easy to say that dangerous particulate matter (PM) generated by mining should be monitored and kept to a minimum; however, it is very challenging to measure the levels of contaminants in the ...

  • Supercooled Liquid Water is Hazardous to our Health!

    What is Supercooled Liquid Water? Supercooled Liquid Water (SLW) refers to water droplets in a cloud that can stay in a liquid state at below freezing temperatures. If an airplane flies into these SLW droplets, icing on the wings and airframe can occur. ...

  • Top 5 Differences between Micro Pulse LiDAR and Ceilometer Technology

    If you are evaluating backscatter LiDAR sensors for measuring aerosols, cloud vertical structure, and planetary boundary layer (PBL) heights, what factors should you consider in your comparison? It really comes down to a choice between the traditional analog technology used in ceilometers and the more recent advanced technology found in Micro Pulse LiDAR (MPL) sensors. ...

  • Micro Pulse Lidar: Perfect Tool for Atmospheric Research

    Micro pulse style lidars are active remote sensing tools proven to be highly useful in atmospheric research. This style of backscatter lidar has been around for decades; however, incremental improvements in photon counting, sensitivity, polarization, optical filters, coatings, and precision machining of each element support increasingly accurate analysis. Each iteration of the ...

  • Multiple Instruments Work Together for a Better View of Air Quality

    Accurately identifying and quantifying particulate matter (PM) in the atmosphere is key to determining air quality. Researchers are particularly interested in PM that have a diameter of less than 2.5 micrometers because they are believed to contribute to heart and lung disease in humans and animals. These tiny particles are invisible to the naked eye and originate from power plants, fires, and ...

  • ENHANCING THE PERFORMANCE OF OXIDATION DITCHES

    Oxidation ditches are very popular wastewater treatment processes for small to mediumsized municipalities that have to meet stringent water quality standards. Oxidation ditches provide cost-effective treatment while requiring relatively simple operational skills. Because carbonaceous BOD removal, nitrification, and de-nitrification can be accomplished within a single reactor, the process can ...

  • TOC analysis at airports

    As other industrial devices airports have to control their run-off weter for TOC and/or COD. The amount of waste water produced at airports is not negligible: The Frankfurt airport (one of the biggest airports in Europe) has produced 1.63 million cubic meters in 2006, the same amount as a medium-sized city. The sewer system of this airport consists of a 200km tubing system with a low quantity of ...

  • Meeting regulations and improving quality case study

    A UK-based waste oil collector was using emulsifiers and heat to drop water out of waste lube oils and fuels. The processed oil with 0.5-1.0% water was being filtered in a centrifuge. The company installed Sequoia’s efficient water evaporation equipment which produces oil with less than 0.1% water. As a result, the centrifuge works more efficiently. Ultimately, the company makes a recycled ...

  • Longterm experience in the use of polymeric coagulants at Umgeni Water

    Umgeni Water, the bulk treatment authority for the cities of Durban and Pietermaritzburg changed from inorganic coagulants to synthetic polymeric coagulants at its various works in the mid 1980s. The advantages and disadvantages experienced with the new chemicals are discussed in detail in the paper and the changes to test procedures necessary are highlighted. The polymeric coagulants were found ...

  • Who will be more active in sustainable consumption? Evidence from China

    Economic growth in China improves the quality of life and income-driven levels of consumption. However, environmental behaviours with regard to water and energy consumption, as well as wastes produced, which have significant impacts on sustainable cities, have scarcely been studied. A survey is conducted to interview about 300 residents in Nanjing, capital of Jiangsu Province, China. Analysis of ...

  • Innovations in the inhibition of reverse osmosis membrane scaling and fouling

    Abstract: Scaling and fouling of membranes is an on-going performance issue for most plants. There are continual improvements in membrane technology and plant design which increase efficiency, water quality and utilise different raw water supplies to produce clean pure water. This presentation outlines innovations in laboratory services and speciality chemicals designed to inhibit membrane ...

  • Water reclamation with hybrid coagulation–ceramic microfiltration: first part of a long-term pilot study in Portugal

    Sustainable water management must nowadays consider alternative water sources and the use of reclaimed water is a good candidate. Low-pressure ceramic membrane filtration is an emerging option for safe water reclamation given its high mechanical and chemical robustness with safety and operational advantages. One-year pilot studies of hybrid coagulation–ceramic filtration were developed in ...

  • Algae Control in Lakes and Reservoirs

    There are plenty of harmful algal bloom related cases worldwide but what is evident is that their number elevates with each year. Excessive cyanobacteria (blue-green algae) and green algae growth in a water reservoir can have negative consequences for the water quality. The water turns green, sand filters can clog, and some algae can produce geosmins and MIB, giving the water an ...
