Holes may be the result of biological slime becoming incorporated into the paper. Slime can be controlled by a biocide program. The paper machine system is especially vulnerable to slime in the headbox area. Since the headbox comes after the pressure screens, any slime that gets entrained into the flow is likely to end up in the paper. Biocide.
Wet painting booths are used extensively in the painting of automobiles and auto parts. Aqueous paint, the most widely used form of paint in this process, contains a large amount of surfactants that may cause many different problems, such as environmental abnormalities and an increase in waste resulting from the formation of foam and poor coagulation. Understanding the ecology of paper mill Sphaerotilus strains is a prerequisite for the development of more efficient control strategies against slime formation. In the present investigation, we used a polyphasic approach to characterize four Sphaerotilus -like isolates of filamentous bacteria obtained from paper mill by:

Slime-producing microbes secrete extracellular polysaccharides that gum up the process machinery. The specific nature of slime and Slime Control in paper mills. book formation depend on the mill environment. Correspondingly, countermeasures vary with the type of slime deposit. Conventional slime control methods generally employ combinations of biocides.
Request PDF | Slime Control | Formation of slime deposits is a major problem facing paper industries. The current papermaking trends have a negative influence on the treatment | Find, read and Author: Pratima Bajpai. Other bacterial species detected in slime are Chlamydobacteriales, Alcaligenes, Arthrobacter, Proteus, Bacillus, Escherichia coli, Pseudomonads, and others.
Bacteria most often found in paper and board machine slime include species of Flavobacterium, Clavibacter, Sphaerotilus, and Leptothrix.
An optimized slime- and deposit control is an essential for a smooth run of every paper machine. Biodispersants gain acceptance more and more in slime control in the paper industry. The paper Author: Pratima Bajpai. • Mill Condensed Vapor Studies – agreed with Lab Studies • Corrosion Coupons in the Vapor Phase – the trend agreed with condensed vapor studies • All agreed with what we see in the “real world PaperCon 26 PaperCon Page Effective Paper Machine Slime Control and No.
Bacteria, yeast and filamentous fungi were isolated from various sites within a paper mill. Bacillus alvei and Aerobacter aerogenes were the most prevalent contaminating bacteria.
Maximum slime was produced by A. aerogenes ( mg ml−1) at pH and. CONCLUDING REMARKS Slime control in the Indian pulp and paper mills continues to be an empirical exercise that is sometimes effective and sometimes not.
Once slime is formed the automatic response usually is to increase the biocide dosage or change the biocide altogether or shut down the machines for boilouts and by: The book provides the most up-to-date information available on various biotechnological processes useful in the pulp and paper industry.
The first edition was published incovering a specific biotechnological process or technique, discussing the advantages, limitations, and prospects of the most important and popular processes used in the : Springer Singapore.
Thermotolerant fungi have been found in slimes at temperatures of 38 to 52 °C in paper mills in Eastern Canada. The growth of some of these isolates on malt agar plates maintained at temperatures of 10 to 65 °C has been by: 5. blockages and pump failures in pulp & papers mills (3).
Biocides are routinely used for slime deposit control in paper mills. They are directed against living organisms, but frequently not restricted to “target organisms”. This implies that they inevitably also can harm the health of non-target organisms such as humans or animals. Biocides. biocide costs at paper machines vary between 1 and 4 €/paper ton.
For average sized fine paper machine this means million Euros annual costs for microbial control. Responsibility for maintenance of microbial control systems has drifted to chemical suppliers, and therefore all the interactions with process, other chemicals, etc.
are seldom. Abstract. Slime control in the paper mill is a major operational problem and expense facing paper companies. At present, slimes are controlled with synthetic organic chemicals, many of which contain heavy metals or are highly halogenated and are currently the focus of regulatory scrutiny An enzyme preparation MX has been developed to:"control" slimes in pulp and paper mills.
The METHYLCHLOROISOTHIAZOLINONE and METHYLISOTHIAZOLINONE are components in biocides, for use as preservatives in oil and cooling fluids, soaps, latex emulsions, slime control in paper mills, jet fuels, milk sampling, radiography, printing inks, moist toilet paper, detergents, shampoos, hair conditioners, hair & body gels, bubble baths, skin.
Of the preparations tested at the Feldmühle Papier-und Zellstoffwerke AG for efficiency in the control of 2 [unnamed] fungi and 1 bacterium particularly resistant to chemicals, which were freshly isolated from the slime of paper mills [cf.

THE ULTIMATE SLIME RECIPE BOOK** Whether you are a child or an adult, slime is ALWAYS fun. You can learn about science, express your creativity, and create a huge collection of unique slimes.

In this study, we explored the composition of the bacterial biota in slime that developed on shower pipes from 2 machines at a Canadian paper by: 3.

Dose at regular intervals and at least once daily. Add to system where agitation is sufficient to distribute material throughout mill. Slime formation is a serious problem nowadays in the paper industry. Some enterobacteria are associated with the formation of slime deposits in paper and board mills.
Detection and characterization of slime forming bacteria, belonging to the genus Enterobacter, Raoultella, and Klebsiella have been achieved by fluorescence in situ hybridization (FISH), using one probe based on the Cited by:.
The Institute of Paper Chemistry estimates that slime-related problems cost the United States paper industry upwards of $ million per year.
The cost could be as high as ten times that without biological control systems or chemicals. Microbiological growth in a paper mill can lead to the following problems: Loss of Production.Most paper machine systems have a relatively high content of sulfate ions due to the use of such additives as sulfuric acid and aluminum sulfate.
The solubility product of barium sulfate is low, so it is common that the formation of barium sulfate is thermodynamically favored in paper mill systems.BUSAN WS PAPER MILL SLIME CONTROL: FOR THE CONTROL OF SLIME-FORMING AND/OR SPOILAGE BACTERIA: BUSAN WS is added at a point in the system (raw stock chest, beater and/or refiner chest, or machine chest-wirepit) where it will be uniformly mixed.
Add to pounds of BUSAN WS per ton of paper produced.
