Industry: paper & pulp

Tends equipment to causticize sodium compounds recovered from paper manufacturing processes: Observes dial indicators, charts, flowmeters, and signal lights on panel to determine level and temperature of solution in reactor tank, rate that chemicals flow into reactor tank, level of lime sludge in settling tanks, and amount of sludge in washers. Starts pumps to control flow of slaked lime and recovered chemicals into reactor tank, causticized solution to storage tanks, and lime sludge through washers to lime kiln, according to specifications. Tests alkalinity of causticized solution by titration, records test results, and computes percentage of caustic in solution, using slide rule.
