  • The Best Water Treatment Systems of 2017

    To be properly hydrated, most people need to drink around two liters of water a day. Because we drink so much water, trace amounts of impurities, chemicals, and hard metals can build up in our bodies over time. Water has become the focus of many health-interested individuals in recent years. For businesses that need clean water, like labs or manufacturing companies, keeping water as clean as ...

  • Guide to Removing Arsenic from Drinking Water

    It’s said that the human body is made up of almost 60 percent water. Is the water you’re putting into your body pure? Many people are unaware of the chemicals and compounds that are seeping into their drinking water and wreaking havoc on their internal systems. Arsenic, for example, can be found in many different areas. In the Northeast especially, well water is more likely to be ...

  • The Benefits of Biological Treatment for Drinking Water

    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 ...

  • 10 Uses of Rainwater

    Collecting your own rainwater is an excellent way to conserve this precious resource. A basic rainwater collection system catches rainwater from your roof or other surface and channels it into a container for storage. Rainwater itself is generally clean, but it can pick up microorganisms, pollutants and debris when it hits your roof. This is why systems for rainwater use inside your home often ...

  • Separating micro pollutants by an innovative membrane process.

    Combined adsorption of micro pollutants on activated carbon and membrane filtration of MICRODYN-NADIR has proven an alternative to the established activated carbon/precipitation/sand filtration process. Contamination of the environment by micro pollutants has clearly been proved by now. Due to the high concentration of microorganisms and the contamination by antibiotics coming from animal ...

  • Water Security – A Growing Issue with No Easy Fixes

    The issue of water security – access to enough quality water to make it possible to live safely – is a growing concern for many, just ask the communities of Flint and Corpus Christie. The problem is exacerbated when communities and companies come face-to-face over access to water supplies. Wouldn’t the nice idea be to share?  That’s met with disagreements as ...

  • Case study - Tarmac - Shireoak

    Tarmac is a leading supplier of aggregates, mortar, concrete blocks, asphalt and ready mixed concrete. The Tarmac Shireoak site north of Birmingham is a bunter sand deposit. Raw Material Analysis The material is spilt 50/50 between sand and gravel but the sand is very fine- typically 30% passes the 300mm sieve, 7% of the raw material is silt. Tonnage: 200,000 ...

  • High-Resolution Ultrahigh-Pressure Long Column Reversed-Phase Liquid Chromatography for Top-down Proteomics

    Separation of proteoforms for global intact protein analysis (i.e. top-down proteomics) has lagged well behind what is achievable for peptides in traditional bottom-up proteomic approach and is becoming a true bottle neck for top-down proteomics. Herein, we report use of long (≥1 M) columns containing short alkyl (C1-C4) bonded phases to achieve high-resolution RPLC for separation of ...

  • Case study - Filtralite in London

    World best filter material for purification of drinking When algal blooms put the sand filters under pressure, Thames Water started its own in-house research into new filter materials. Not only did the effort cure the constraint, the use of new filter materials has saved millions in investments. Fast Cleaning To purify water with sand takes a long ...

  • Oil Sampling Best Practices (Part 2)

    Understanding Dynamic Particle Equilibrium in Closed Loop Systems Dynamic Equilibrium Condition (DEC) is defined as a steady state condition where the normal wear rate in a machine results in no net gain or loss of particles. ...

  • Novel mixed-mode stationary phases for chromatographic separation of complex mixtures of decomposed lignin

    Abstract Electrochemical degradation of lignin results in a large number of unknown products, formed by both oxidative and reductive decomposition pathways, which have previously been studied by direct mass spectrometry experiments without prior liquid chromatography separation, revealing the presence of many isobaric molecules. In this study, novel phosphonium-based ionic liquid stationary ...

  • Emulsified Oil Injection: Is smaller always better?

    Many professionals assume that the smallest oil droplets will transport the farthest during subsurface substrate injection.  However, this is not always true.  Water treatment engineers have studied particle (and droplet) removal in sand filters for decades.  They have learned that particle removal is a function of the frequency of particle-sand grain collisions and the probability ...

  • Effects of C/N ratio on nitrous oxide production from nitrification in a laboratory-scale biological aerated filter reactor

    Emission of nitrous oxide (N2O) during biological wastewater treatment is of growing concern. This paper reports findings of the effects of carbon/nitrogen (C/N) ratio on N2O production rates in a laboratory-scale biological aerated filter (BAF) reactor, focusing on the biofilm during nitrification. Polymerase chain reaction–denaturing gradient gel electrophoresis (PCR-DGGE) and ...
