分形是对高度不规则的几何形状的数学描述。研究表明，水和废水处理过程中产生的颗粒团聚体具有分形特征。在这项工作中确定的聚集体的结构的分形维数，范围从1.4到2.8。分形维数的概念被发现适用于聚集体的几何特征，在基板转移到生物聚集体，并在聚集过程中。
A fractal is a mathematical description of highly irregular geometric shapes. It is demonstrated that particle aggregates generated in water and wastewater treatment processes possess fractal features. The fractal dimension for the structure of the aggregates, determined in this work, ranged from 1.4 to 2.8. The concept of the fractal dimension is found applicable in the characterization of the aggregates'' geometry, in substrate transfer to biological aggregates, and in the process of aggregation.
