Abstract |
Raw waste loads from the hardboard industry are characterized. Factors that affect the raw waste load are studied. The raw waste load is most strongly affected by the wood cooking conditions. More of the wood is dissolved at the higher pressures and temperatures found in production of smooth on one side (S1S) board, which results in higher raw waste loads for smooth on two sides (S2S) production. Additional wood is dissolved in the hot press in the production of S1S board. Refining of the wood results not only in production of solids, but also in production of wood fines that add to the raw waste load. Recycling of whitewater and press pit waters reduces the quantity of discharge from a hardboard mill. Raw waste loads are also decreased. Dissolved solids, suspended solids, and the temperature in the whitewater increase with increased recycling. The change in the raw waste load and whitewater characteristics are most dramatic when nearly all the process waters are being recycled. |
