  • Optidose polymer

    Maintaining a minimum concentration of an effective dispersant polymer is crucial in an alkaline cooling water treatment program. The problem is knowing exactly how much polymer is available in the cooling water to combat fouling and corrosion of heat transfer equipment. Many years of research and effort have gone into the development of a method for tracing the concentration of polymers. Rohm ...

  • Success with water-soluble polymers

    An industrial waste treatment system in Texas used AQUACLEAN / ACF-32 in their plant to reduce BOD, Ammonia, TOC, and TSS. This industrial site was processing water-soluble polymers that were proving to be difficult for their activated sludge system. In the existing system design, the influent stream is first treated by a pH adjustment to a level of 12 or higher, and then is later anaerobically ...

  • Polymer nanocomposites reinforced with polysaccharide nanocrystals

    Aqueous suspensions of polysaccharide nanocrystals can be prepared by acid hydrolysis of natural resources, such as cellulose, chitin and starch. The object of this treatment is to dissolve away regions of low lateral order so that the water–insoluble, highly crystalline residue may be converted into a stable suspensoid by subsequent vigorous mechanical shearing action. When using cellulose or ...

  • Hydro Polymers: Searching for a More Sustainable PVC

    Over the last five years, the European PVC industry has been forced to reassess the environmental impact of its products in the face of continuing pressure from environmental groups, governments and end users. Hydro Polymers, one of two PVC manufacturers in the UK, is forging ahead of its competitors through a partnership with sustainability consultancy The Natural Step. The company is launching ...

  • Influence of nanoparticles on the polymer-conditioned dewatering of wastewater sludges

    The effect of using small-scale, high surface area, nanoparticles to supplement polymer-conditioned wastewater sludge dewatering was investigated. Aerobically digested sludge and waste activated sludge sourced from the Hunter Valley, NSW, Australia, were tested with titanium dioxide nanoparticles. The sludge samples were dosed with the nanoparticles in an attempt to adsorb a component of the ...

  • Biological denitrification of drinking water using biodegradable polymer

    The application of Biodegradable Polymer (BDPs), which can serve as biofilm carrier and simultaneously as water insoluble carbon source for heterotrophic denitrification. The external dosing of soluble organic substrate can be therefore avoided and process can be simplified as normal bio-filter. In this paper, the lab-scale experiment was carried out by using the cheap material of PBS, a new kind ...

  • Hybrid materials of conducting polymers with natural fibres and silicates

    The preparation, characterisation and properties of new hybrid materials of the conducting polymers polypyrrole and polyaniline with cellulose substrates in the form of paper fibres, paper sheets and wood; merino wool fibres; and kaolinite particles are presented. The conducting polymers form as spheres of about 50-150 nm that are fused together as a continuous coating which fully encapsulates ...

  • PEDOT–PSS/MWCNT coatings on PET for conducting polymer actuators

    The electrochemical deposition of a conducting polymer on a non–conductive polymer requires a conductive layer, which can be achieved by sputtering or vaporisation of precious metals such as gold or platinum. In this investigation we coated poly(styrenesulphonate) doped poly(3,4–ethylenedioxythiophene)/multi–walled carbon nanotubes (PEDOT–PSS/MWCNT), in a ratio of 2.4 : 1 on a poly(ethylene ...

  • Diafiltration of polymers with VSEP provides unprecedented performance and product quality with no pretreatment

    Recent technological advances in membrane architecture and system design have created a new opportunity for efficient diafiltration or desalting of various organic polymers and inorganic chemicals. V✧SEP, (Vibratory Shear Enhanced Process), developed by New Logic makes it possible to wash larger solutes and remove smaller contaminant solutes without the fouling problems exhibited by ...

  • Synthetic organic polymer fouling in municipal wastewater reuse reverse osmosis

    A full scale waste water reuse plant suffered from irreversible fouling of the reverse osmosis (RO) membranes. The major suspect of fouling is cationic organic polymers applied in the wastewater sludge treatment. Thus, the purpose of this research is to study the effect of six cationic polymers, applied in the plant, on RO membrane performance. The filtration and adsorption experiments with 4 mg ...

  • The design of static mixer heat transfer equipment for adhesives, sealants, resins and polymers.

    The fluids handled within the adhesives and sealant industries are amongst the most difficult to handle of any in the main process industries globally. The characteristics which make them particularly difficult to handle include: High viscosities (typically 1-2000 Pa.s, or 1000 to 2 million cP). Often non-Newtonian (viscosity is not constant and varies with shear rate). Some ...

  • Physical properties of magnetic metallic nanowires and conjugated polymer nanowires and nanotubes

    The unique physical properties of nanowires and nanotubes originate from either the small dimensions of the objects, or structural modifications induced by the confined synthesis and surface effects. These features make them very promising for applications in nanoelectronics and nanosensors in particular. In this paper, we review our results on magnetic metallic nanowires and conjugated polymer ...

  • Imprinted polymers for the removal of heavy metal ions from water

    In wastewater treatment, the removal of heavy metals is difficult due to the limited affinity of heavy metal ions to ion exchange resins. Here imprinting polymerization is used to develop resins with high capacity and selectivity for heavy metal ions for water treatment. A random copolymer of methacrylate and methacrylamide was found to be most effective for the removal of hydrophilic metal ...
