  • Mixing of Drying Air: Increasing the Absorbency

    High-quality tissue paper is today produced using TAD (through-air-drying) technology, which is widely established as the most efficient drying method to increase bulk and softness in commercial tissue production. In the TAD process, it is essential to ensure uniform temperature distribution in the stream of drying air in order to achieve superior quality in terms of the softness and absorption ...


  • History of super absorbent polymer chemistry

    Until the 1980’s, water absorbing materials were cellulosic or fiber-based products. Choices were tissue paper, cotton, sponge, and fluff pulp. The water retention capacity of these types of materials is only 20 times their weight – at most. In the early 1960s, the United States Department of Agriculture (USDA) was conducting work on materials to improve water conservation in soils. They ...

  • Comparison between ultrafiltration and nanofiltration hollow-fiber membranes for removal of natural organic matter: a pilot study

    Increasing trends of natural organic matter (NOM) in surface water in Nordic countries may cause future problems for drinking water producers. Emerging membrane technology, such as ultrafiltration (UF) and nanofiltration (NF), has the potential to produce safe drinking water of good quality from sources with high organic concentrations. In the present pilot study, surface water from three ...

  • An Unmatched Combination of Carpet Cleaning Machines and Green Chemicals

    A nice carpet can perk up the appeal of your room. But, as carpet fibers are highly absorbent, they quickly accumulate dust, dirt, oil, and stains. The traditional technique of vacuuming is effective only for removing particles on the surface. Constant scrubbing with harsh brushes can actually do more harm than good to your carpets because delicate fibers can be damaged by excess water and ...

  • Using Coir Geotextiles for soil erosion control

    One of the most effective and yet natural soil erosion prevention techniques is the use of Coir Geotextiles fabrics ( Woven Geotextiles). Used extensively to prevent environmental degradation Geotextiles have no synthetic material but is instead made out of an organic fiber, coir, which is extracted from the husk of a coconut. It is strong, durable, water proof and is one of the few natural ...

  • Confirmation of the correlation between membrane fouling in microfiltration and biopolymer concentrations in various Japanese surface waters

    A variety of surface waters used for drinking water sources were collected from different parts of Japan to investigate a correlation between the concentration of hydrophilic biopolymer (e.g. proteins and polysaccharides) in the feed water and membrane fouling in microfiltration. Hollow-fiber membranes made from polyvinylidene fluoride with a nominal pore size of 0.1 μm were used in the ...

  • Carpet Cleaner That You Need for Restaurant Maintenance

    Maintaining carpets is not an easy job. Due to their porous nature, carpets absorb dirt, oil, and stains really fast. When it comes to high-traffic areas such as malls, schools, retail stores, or restaurants, the tough cleaning job gets tougher. As more people walk into these places, the more dust, dirt, and stains the carpets collect. To get exceptional cleaning results, it is best to ignore ...

  • Analysis of TNT and RDX in groundwater

    MATRIX: Water ANALYTE: TNT and RDX LIMIT OF DETECTION: TNT 1 ppb (mg/L), RDX: 5 ppb (mg/L) BACKGROUND: This application describes a field screening method for determining TNT and RDX concentrations in water. The method uses solid phase extraction to remove and preconcentrate the analytes from water. In the method, a 2 ...


  • 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 ...

  • What is a Spectrometer?

    The characteristics of a white LED light differs greatly, when compared to a yellow CFL. Without any special tools, one can see that the LED emits a clear white color, while the CFL generates yellow light. Going one step further, using a spectrometer, one will be able to “dissect” the light sources and see that they are composed of other colors in the visible light spectrum, such as ...

  • Application of a Medium Pressure UV System for the Treatment of N-Nitrosodimethylamine (NDMA)

    N-nitrosodimethylamine (NDMA) was first detected in 1990 as a problem pollutant in drinking water wells at levels as high as 3,000 ppt in Elmira, Ontario, Canada. The waste from a large chemical plant over many years had led to the contamination of the drinking water wells for the community. After extensive evaluation and testing, it was determined that UV photolysis was the most effective ...

  • Measuring IR Light and Near-IR Light

    Infrared (IR) light emits a broad range of non-visible wavelengths in the electromagnetic spectrum. Applications for infrared, including near-infrared, are defined by the respective IR bands during output. For example, LIDAR (Light Detection and Ranging) equipment uses 1,000 nm and 1,550 nm IR bands while surveying an area. In the military sector, 850 nm, 1,060 nm and 1,500 nm (and up) are used ...
