Wash And Mother Liquors: The discharge procedure, which may be assisted by air blow-back, leaves no heel of cake and thus in situ Filter medium cleaning is readily performed. As all liquors are kept separate, there is little unwanted mixing of mother and wash liquors and countercurrent washing can be very good. Tilting pan filters are available with total Filter cloth areas up to 200 m2, however, many of their inherent advantages are offset by their mechanical complexity and high capital cost.
Dependent on the properties of the solids forming the cake, the presence of the heel can have undesirable consequences for future cycles and necessitates the use of more open Filter media with the potential for cloudier filtrates. As the filtration surface is not physically divided into individual sectors some short-circuiting of the feed may occur as well as unwanted mixing of the wash and mother liquors. Cloth washing is difficult and must be performed off the filter. Although cloth area can be up to -200 m2, alignment difficulties usually restrict machine size and the available Filter area to less than 20 m2.
FOOD: When first taken from mother give warm milk in clean saucer 4-5 times daily. After a few days, add stale bread to warm milk. In week or so, give a little cooked cereal with milk. Occasion-ajly give small amount of finely chopped, cooked meat; never give raw meat to a kitten. Place all food in containers used only for pet; wash containers daily; keep food containers separate from household's dishes and wash separately. Water—Essential; must be clean, fresh, and available at all times. |
