小型系统的处理技术应具有较低的建设和运营成本、简单的操作、较低的维护和无严重残留处置问题。由于许多小型系统的员工很少或没有员工，因此该流程必须适用于兼职操作。满足部分或所有这些条件的工艺包括混凝过滤成套设备、硅藻土过滤、慢砂过滤、离子交换、颗粒活性炭和空气剥离。也可以使用反渗透、石灰软化和活性氧化铝。所有这些过程都是根据能力和成本进行评估的。 包括17个参考文献和表格。

Treatment technologies for small systems should have low construction and operating costs, simple operation, low maintenance, and an no serious residual disposal problems. Because many small systems have few or no employees, the process must be adaptable to parttime operation. Processes that meet some or all of these conditions are coagulation-filtration package plants, diatomaceous earth filtration, slow sand filtration, ion exchange, granular activated carbon, and air stripping. Reverse osmosis, lime softening, and activated alumina may also be used. All of these processes are evaluated based on capability and cost. Includes 17 references, tables.
