Abstract
Particles in sludge feeds interact strongly one with another to prevent settling and offer a significant resistance to filtration and compression. This leads to the need for dewatering forces to be compressive ones applied directly to the networked solid phase; sometimes shear forces can be an assist dewatering. Designs of filtration equipment most suitable for sludge dewatering have evolved to meet the intrinsic characteristics of sludges, the most important of which are their compressibility and fine particle sizes, which lead to cakes with extraordinarily high solids contents close to the filter medium. Hence, the membrane plate press, the belt filter and the decanter centrifuge have become most widely accepted machines for sludge dewatering. Filter presses tend to yield a drier solids discharge, but the level of dryness depends on the sludge properties. The same feed properties dictate the need for chemical pre-treatment to ensure the highest rates of

摘要颗粒饲料污泥强烈的互动与另为防止和解决提供了重大的阻力过滤 与压缩. 这导致了需要脱水势力被压缩的直接应用于网络固相; 有时剪切力是一种可以协助脱水. 图案过滤设备最适合污泥脱水已演变以满足固有的特性淤泥 其中最重要的是他们的压缩和细颗粒尺寸, 导致饼黄庭高固体含量密切的过滤介质. 因此,膜板新闻 带式过滤机和离心机已经成为最广为接受的机器进行污泥脱水. 压滤机倾向于迁就干燥固体的排放量,但#56燥取决于污泥性质. 相同的饲料特性,因此,必须进行化学前处理,以确保率最高的脱水和最佳清晰度 滤,正确选择滤布,也是很重要的,在这方面的政策.
