  • It’s Time To Choose An Environmentally Friendly Absorbent Product

    With media headlines constantly reminding the public about pollution and dwindling resources, no business should put off making the strategic decision to go green. Still not convinced? Consider this: going green as a business is good for two reasons. As we already touched on, in this day and age the public image of a business is more important than ever; one wrong move and you’ll come under ...

  • A pump-less discrete opto-fluidic chemical spectrophotometry system (DOCSS) for online in situ monitoring of dissolved contaminants in aqueous media

    This paper presents the fabrication of a discrete chemical analyzer system for online monitoring of dissolved ions in water using UV-VIS absorption spectrophotometry. The device is composed of three main components: fluidic, optical, and control. The test cell was designed to also function as a non-invasive volume sensor, and the volume sensing principle was based on light scattering by ...

  • The Power of the Moon

    The influence the moon has on life on earth is disputed. However, during an assignment in Southeast Asia, vibration experts from Sulzer were able to clearly confirm that the moon can even affect pumps. With its broad expertise, the Sulzer team was able to solve an unusual case of vibration. Southeast Asia is a key exporter of LNG (liquefied natural gas) to global markets, and it is ...

  • A Laplace transform exponential method for monoenergetic three-dimensional fixed source discrete ordinates problems in Cartesian geometry

    We describe a Laplace transform exponential method applied to x-y-z geometry heterogeneous neutron transport problems in the discrete ordinates (SN) formulation that we refer to as the LTSN – Exp method. This numerical method uses the space Laplace transform technique to solve the one-dimensional transverse-integrated SN exponential equations within one of the homogeneous regions of the ...

  • LiquiSorb 200 saves time and money before the rubber hits the road

    Problem In tire manufacturing there is much more to the finished product than just rubber. Tire chords, a by-product of the manufacturing process, are coated with a proprietary dip solution that acts as a flexible adhesive/bond in tires. This dip solution has an extremely high concentration of solids in water, making traditional wastewater treatment techniques less effective, extremely slow, and ...

  • From Wastewater Treatment to Sweet Pineapples

    In wastewater treatment, ammonia that is removed from sewage used to be discharged directly to the atmosphere. Nowadays, studies have identified that ammonia emissions are of major concern to air quality. This has led to a new way of thinking. Sulzer offers modern closed-air-loop systems for wastewater treatment that transform ammonia into a common soil fertilizer. This reuse of a waste product ...

  • Ecotoxicity of multiwalled carbon nanotubes: Standardization of the dispersion methods and concentration measurements

    There is currently a variety of applications for multiwalled carbon nanotubes (MWCNTs), but considerable concerns exist regarding their release into the environment. Their potential accumulation by aquatic organisms could lead to a transfer throughout food chains. Considering the divergences in experimental data published on ecotoxicity of carbon nanotubes, further research is required. The ...

  • SnowPure Tip: Effective CO2 Removal

    CO2 is difficult for both RO and EDI to remove since it has no charge or is weakly ionized. It is important to remove CO2 in the electrodeionization pretreatment because CO2 lowers EDI product water quality, competes with silica for removal, and may lead to scaling ...

  • Spectrophotometric monitoring of nitrite in seawater after liquid microextraction of its derivative with 2,3-diaminonaphthalene

    A simple dispersive liquid–liquid microextraction based on solidification of floating organic droplets coupled with spectrophotometric detection was developed for the determination of nitrite in Chabahar Bay seawater. In the preparation procedure, 2,3-diaminonaphthalene as derivatization reagent reacts with nitrite in acidic medium to form a photometric center of 1-[H]-naphthotriazole (NAT). ...

  • Effective Co2 Removal

    CO2 is difficult for both RO and EDI to remove since it has no charge, or is weakly ionized. It is important to remove CO2 in the EDI pretreatment because it will lower the EDI product water quality, will compete with silica for removal, and may lead to scaling of the EDI. Here are 3 ways to remove CO2 effectively in a system: Corosex II absorbant media, prior to the RO Benefits: ...

  • The no. 1 choice for improving the performance of soil and groundwater remediation

    Adsorption of Contamination The number one challenge associated with most site remediation designs and methodologies is that 90% to 95% of all environmental contaminants; including hydrocarbons (LNAPL), chlorinates (DNAPL), and heavy metals; are present in a sorbed (i.e., absorbed or adsorbed) phase onto soil and bedrock surfaces within both saturated and unsaturated zones. As such, the absorbed ...

  • Mastering the Chaos

    Random packing consists of single pieces that are poured into separation columns and form a chaotic structure. Now, Sulzer has developed a new generation of high-performance random packing that offers more uniformity of surface distribution within the packing volume. The example of a CO2 absorber shows the benefits. Columns with random packing are well established ...

  • Feasibility Study of Using Brine for Carbon Dioxide Capture

    ABSTRACT A laboratory-scale reactor was developed to evaluate the capture of carbon dioxide (CO2) from a gas into a liquid as an approach to control greenhouse gases emitted from fixed sources. CO2 at 5–50% concentrations was passed through a gas-exchange membrane and transferred ...

  • Cost reduction of solvent recovery in pharmaceutical plants – Case Study

    Use of Solvents The pharmaceutical industry relies on the use of large quantities of organic solvents in a great number of manufacturing steps including chemical synthesis, fermentation, extraction, formulation and finishing of products. Solvents such as acetone, methyl ethyl ketone and tetrahydrofuran are commonly used as reaction media and for extracting products in the ...

  • Liberating contaminants for easy recovery

    The number one challenge associated with most site remediation designs and methodologies is that 90-95 per cent of all environmental contaminants are present in an adsorbed phase onto soil and bedrock surfaces within both saturated and unsaturated zones. Contaminants, including hydrocarbons (LNAPL), chlorinates (DNAPL) and heavy metals, are sorbed onto the substrates and so have reduced mobility ...

  • How to Choose the Right Biological Water Filtration System

    There are many different biological treatments of water available. They’re all similar in a number of ways, but share key differences in the specific ways the water is filtered. This article is an informative breakdown of all the different biological water treatment systems that are available and how they ...

  • It’s Time to Rethink Cooling Tower Filtration

    ABSTRACTThe dissipation of ambient or process heat in large HVAC systems, manufacturing facilities, power generation plants, refineries, metal mills and forges, chemical plants and food processors is most often accomplished by cooling towers. These simple structures facilitate the transfer of unwanted energy (heat) from a transport liquid (usually water) to the atmosphere. The bane of cooling ...

  • The Different Kinds of Dust Collection Booths

    Factories that produce heavy dust particles require a dust collector system in place, so employees can breathe in clean and pure air at all times. Also, with one of these systems in place, machinery functions well and lasts longer. Dust collection booths also help limit dust into a closed area and safely trap it inside a closed space for ...
