摘要： An efficient method of continuously treating normally dilute aqueous solutions of cellulosic pulp which routinely flow from pulpmaking or papermaking process devices to effect separation and retrieval of small amounts of desirable fiber therefrom while letting small contaminants and undesirable fiber parts flow through to the sewer and also to effect retrieval of desirable fiber during periods of high fiber loading which result from upstream catastrophic failures by utilizing an open cell hydrophobic foam separation medium on a drum or belt filter. The foam medium has a thickness within the range of from one-eighth inch to two inches and a porosity within the range of from forty to eighty pores per lineal inch.
摘要翻译：连续处理纤维素纸浆的常规稀释水溶液的有效方法，其通常从制浆或造纸工艺装置流出，以实现从其中分离和回收少量所需的纤维，同时使小的污染物和不期望的纤维部件流入下水道，并且还通过在鼓或带式过滤器上利用开孔的疏水性泡沫分离介质，在高纤维负荷期间效果检索期望的纤维，这是由上游灾难性故障引起的。泡沫介质的厚度在八分之一英寸至两英寸的范围内，孔隙率在每英寸直线的四十至八十个孔的范围内。
