Background

Besides being a component of many industrial products, it also serves several other important purposes in upstream operations such as transport medium and washing agent.  As is the case with all situations where water is used, microbial growth is ever present if not adequately monitored and controlled.  For example, in the papermaking industry, microbial growth in make-up water streams, process waters, slurries, and on the paper sheet itself can all lead to significant product quality issues such as odors, discoloration, and breaks.  It is therefore critical to assess all entry points where water is used, assess its tendency to support growth, and monitor growth trends in order to keep proliferation in check at all times.

Additional Information:

The QGA method is similar in design to ASTM Standard D4012 for the measurement of ATP in water. The full standard can be obtained here: http://www.astm.org/Standards/D4012.htm.

How can ATP monitoring help?

LuminUltra is the first and only ATP monitoring supplier with products designed for microorganism quantification in any industrial water and wastewater application. The control of microbial growth is an important aspect of nearly every water operation of a manufacturing facility, and we have a product specifically designed for each one!

The following benefits can be realized through a routine ATP monitoring program at applicable process locations:

  • Routinely assessing biocide effectiveness in paper process waters
  • Protection of product quality by preventing deposit formation, discoloration, and product integrity issues.
  • Managing foul odours and explosive gas formation.
  • Evaluate raw water quality and prevent raw water treatment equipment fouling or corrosion.
  • Monitor and control microbiological re-growth in treated water distribution.

Types of Papermaking

  • Chemical Pulping – this involves the addition of aggressive chemicals to wood chips to break up pulp fibers into a slurry.  Depending on the chemical treatments used, chemical pulping can be subdivided into two types:  
    • Kraft/Sulfate Pulping – involves treatment of chips with a sodium hydroxide/sodium sulfide mixture, which is also known as “white liquor”.  Kraft pulp generally produces strong paper.

    • Sulfite Pulping – rather than using highly alkaline liquors, sulfite pulping uses acidic chemical treatment (e.g. sulfurous acid) together with various buffering compounds.  It results in a lighter pulp that is easier to bleach and refine, but may not be as strong as kraft pulp.

  • Thermo-mechanical Pulping (TMP) – rather than using chemical treatments, TMP is done by heating chips with steam and mechanically breaking apart the pulp fibers.  This process often occurs in multiple stages.

Types of Insulation

  • Fiberglass – One of the most common types of insulation due to its excellent resistance to heat transfer, dampening effects to sound, and overall ratio of energy investment to energy savings.

  • Mineral (Rock) Wool – This product is made through steam-treating or pulverizing rock to produce a fiber mass, with binders added to hold the fibers in place.

  • Asbestos – Due to its carcinogenic tendencies, asbestos insulation has been banned for use as a building material in most jurisdictions.  When used in the past, asbestos had shown to provide good sound absorption and resistance to heat.

Automotive Manufacturing

  • Electrophoretic deposition (EPD) - a term for a broad range of industrial processes which includes electrocoating, e-coating, cathodic electrodeposition, and electrophoretic coating, or electrophoretic painting. A characteristic feature of this process is that colloidal particles suspended in a liquid medium migrate under the influence of an electric field (electrophoresis) and are deposited onto an electrode. All colloidal particles that can be used to form stable suspensions and that can carry a charge can be used in electrophoretic deposition. This includes materials such as polymers, pigments, dyes, ceramics and metals.

Types of Textile Manufacturing

  • Animal Textiles (e.g. wool, furs, silk) – originates from animal hair.
  • Plant Textiles (e.g. cotton, hemp, straw) – originates from plant material that is grown and harvested for the purpose of industrial processing.
  • Mineral Textiles (e.g. Asbestos, glass fiber) – Rather than clothing, mineral textiles are more commonly used for building materials.
  • Synthetic Textiles (e.g. Polyester, nylon, polyurethane) – These products are chemically prepared and are used most commonly in clothing.
