In times of trouble, a quick checkand-compare can be carried out and the culprit can usually be identified. Apart from the obvious and the commonsense, which once again must be checked first, there are three main parameters which should be monitored regularly, namely: conductivity, COD and cationic demand. (a) Changes in conductivity can be due to (i) increased addition of inorganic salts such as alum and polyaluminium chloride, (ii) dissociation of chalk, (iii) use of gypsum as filler and (iv) use of coating additives.
3. 7 General structure of bacteria. to eliminate these. Other problems listed above associated with microbiological activity will not be addressed here. 1 Types ofmicroorganisms. Microbiological problems can be caused by any or all of three distinct groups of organisms, called bacteria, fungi and algae. These can be further subdivided in accordance with the following: Bacteria spore forming (anaerobic) non spore forming (aerobic) Fungi mould fungi yeast fungi Algae blue-green algae green algae Most problems encountered in the papermaking process are associated with bacterial activity.
