  • Pulp and Paper Processing

    Application of enzymes in the pulp and paper industry Waste paper-enhancing enzyme: Waste paper-enhancing enzyme is a biological protein that is genetically modified and deeply fermented. It can break the primary wall of secondary fibers and improve fiber binding capacity. Because it is a biological product, it is degradable, and the wastewater produced in the production can be completely reused ...

  • Managing livestock diets to reduce greenhouse gas emissions

    Scientists in South East Asia have been measuring greenhouse gas (GHG) emissions from goats and cattle in a series of research projects investigating the effects of different feeding regimes. In each case, the eructed, or belched, emissions from each animal were measured with a ...

  • EPA Proposes TSCA CDR Revisions and Update to Small Manufacturer Definition for TSCA Section 8(a)

    On April 12, 2019, the U.S. Environmental Protection Agency (EPA) released a proposed rule that would amend the Toxic Substances Control Act (TSCA) Section 8(a) Chemical Data Reporting (CDR) requirements and the TSCA Section 8(a) size standards for small manufacturers. The current CDR rule requires manufacturers (including importers) of certain chemical substances listed on the TSCA Chemical ...

  • Wastewater Treatment Methods Pros and Cons: Disinfection & Coagulation

    At every stage in a wastewater treatment process is important to achieve the desired treatment results. However, primary treatment and tertiary are critical to the overall process. In the primary treatment process solids are reduced to a large extent. Without this step, subesequent treatment would be less effective. In tertiary treatment, harmful microbiological matter is rendered inactive or ...

  • Pushing Water Reuse to The Extremes

    Large-scale water-reuse treatment plants have had a sustainable impact in populated areas where the volume of water to be treated and reused in a concentrated area makes them practical. Today, the flat-sheet membrane aerated biofilm reactor (MABR) technology that is delivering high-quality wastewater treatment to remote locations is poised to realize the promise of sustainable water reuse in ...

  • Taking Back the Power: How Becoming Accountable for Climate Change Will Drive Us Forward

    One thing has become clearer and clearer the longer I am in the sustainability field. To have even the remotest chance of reducing the impact of climate change, we need action across all levels of society – government, business, and local communities – and that needs to start on an individual level. Multi-stakeholder action is not a new notion by any means, yet despite its simplicity, ...

  • Micro Pulse LiDAR: A Critical Tool for Emissions Source Detection

    Micro Pulse LiDAR remote sensing data are used to calculate a highly accurate Planetary Boundary Layer (PBL) height to improve plume models that help assess emissions sources. Poor air quality is a growing health issue that has a negative impact on the quality of life for millions of people. To help alleviate this serious problem, scientists at Bubbleology Research International (BRI) have ...

  • 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. SLW droplets larger than 30 microns create the biggest hazard for aircraft because they don’t freeze immediately, allowing them ...

  • 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 ...

  • Researchers are Advancing Science Using Micro Pulse LiDAR Technology

    There are so many examples of interesting research using Micro Pulse LiDAR (MPL) technology it is difficult to decide on my favorites; however, I have chosen to highlight the following two papers because these applications for the MPL and MiniMPL address problems that are very important to global health. I’ve created a summary of each report and provided the citation in case you are ...

  • 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. To select the best tool ...

  • 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 ...

  • Acid Protease Enzyme

    Definition of Enzyme Activity1g solid enzyme powder (or 1mL liquid enzyme), at 40 C, pH 3.0 (disodium hydrogen phosphate — citric acid buffer), hydrolyzes casein and produces 1ug tyrosine within 1 minute, that is, a unit of enzyme activity, expressed as U/g (U/mL).Acid Protease Enzyme Powder AppearancePowder: Brown powder, good fluidity 40 mesh screening rate≥90%, dry weight loss ...

  • Protect Waterworks From Flooding with Wastop Access Case Study

    Problem: Rising sea levels and extreme weather conditions are becoming increasingly common. Wherever we live on the earth, climate change affects us all. One issue that has therefore become increasingly relevant and important in recent years is to protect people and communities from flooding in waste water and surface water systems – which can have disastrous ...

  • What are Core Samplers?

    A core, in marine research, is a cylindrical section taken from sediments underlying a water body. Core samplers, the instruments used to obtain cores, range from the simple to the complex. The variety of corer types reflect the breadth and variety of marine research. For example, the simplest corers are hand-operated types used in shallow waters to collect sediment cores containing fauna. ...

  • What are Kemmerer bottles?

    Based on a 1927 design by Dr. George Kemmerer, University of Wisconsin, the Kemmerer bottle has long been favored by limnologists and fishery biologists. With few moving parts and a foolproof trip, it offers a trouble-free life. Clear acrylic cylinders have the advantage of being transparent: you can see the sample before removal. You can also install thermometers inside acrylic samplers. ...

  • New requirements for safe use and storage of liquid nitrogen and dry ice

    The College of American Pathologists ("CAP")recently imposed new requirementsto address risks related to the use and storage of liquid nitrogen ("LN2") and dry ice. Background The new requirements come after a deadly incident in 2017, when liquid nitrogen leaked at a Georgia lab that was not accredited through CAP.  Emergency responders were called to the scene when an employee ...
