MIT Jar Test of the Natural Polymer Chitosan with Fresh Pond Water from the Cambridge Water Department, November-December 1992

摘要

The purpose of the MIT (Massachusetts Institute of Technology) jar tests of chitosan using CWD (Cambridge Water Department Treatment Plant) water was to demonstrate the effectiveness of chitosan as a coagulant in drinking water applications. The approach was to compare the performance of the natural organic coagulant, chitosan, to the performance of alum and other chemical coagulants in terms of the parameters turbidity, color, pH and alkalinity. Twenty-five jar tests were conducted during November and December, 1992, at Parsons Laboratory, MIT, Cambridge, Massachusetts.
