Mechanical Pulp - an overview | ScienceDirect Topics

Mechanical pulp mills using the chemithermomechanical pulping (CTMP) process produce effluents with much higher levels of BOD and COD and that are much more toxic to aquatic organisms. Effluents from CTMP mills are also much higher in BOD, COD, and toxicity than those from mechanical pulp mills using older mechanical pulping processes such as

Comparison of Chemical Pulping and Mechanical Pulping

The pulping process is an important link in the papermaking industry. To learn why it is important, we have to start from the pulp. Paper pulp can be classified mainly into two types by the pulping methods: chemical pulp and mechanical pulp. The chemical pulp is produced through the chemical pulping process, while the mechanical pulp is produced through mechanical pulping.

Mechanical pulping - Wikipedia

Mechanical pulping is the process in which wood is separated or defibrated mechanically into pulp for the paper industry. The mechanical pulping processes use wood in the form of logs or chips that are mechanically processes, by grinding stones (from logs) or in refiners (from chips), to separate the fibers. Mechanical pulp can also be bleached to increase the brightness, but retaining the lignin in the

MECHANICAL PULPING – TMP / CTMP 1 Thermo-mechanical

MECHANICAL PULPING – TMP / CTMP 1 Thermo-mechanical Pulp (TMP) Mechanical pulping consumes a great deal of electrical energy. Much effort has been spent over the years to reduce this. A major early approach was the use of higher temperatures to “soften the lignin”. This occurs in RMP by the steam generation in the process.
