Waste water treating method for irrigation purpose in house, involves separating waste water into fraction of water with contaminant of specific level and another fraction of water with contaminant that exceeds specified level

摘要

The method involves separating waste water into a fraction of water with a contaminant of a specific level and another fraction of water with a contaminant that exceeds the specified level. The destination of the waste water is determined based on the level of contaminant in the waste water, and the level of pollution is determined by the extent of chemical contamination of the waste water. The former fraction of water is drained through a special water collection system, and the latter fraction of water is drained through a regular sewerage system. An independent claim is also included for a device for treating waste water.
