| Abstract | Van Diem Paper Mill is a small integrated paper mill that uses bagasse and waste
paper as raw material. The mill manufactures carton board, cover paper, pupil note-book
cover. It was found that upsets and spills occurred frequently as a result of the old
process. The production capacity was found to be 9 tons/day when the mill was running
normally.
Water balance, material balance and energy balance were drawn for the mill. The
water consumption on an overall basis was found to be 376 m
3
per ton of product. The
suspended solid (SS) in the wastewater was 431.8 kg/ton of product. The fiber loss from
the paper machines was considerable with the value of 20.8%. The total of SS and SS70
(parameter used to assess the fiber loss of a paper mill) discharged to the Red river was
369.7 kg/ton and 211.7 kg/ton respectively.
The high concentration of alkaline vapour (0 .187 mg/L) in the digester plant was a
severe source of air pollution in the mill.
The cleaner production opportunities for the mill were studied. Stream segregation
with black liquor collection could reduce pollution load and get benifits. Good-housekeeping practices was especially recommended such as repairing all leakage, keeping
taps closed when they are not in use and cleaning rolls in paper machines. |
