Can a water treatment system treat anything I pour down my drains?
Definitely not!
Remember, sometimes we rely on living bacteria to reclaim the water. There are many substances that will create problems or interfere with their ability to remove contamination. Acids or caustic materials shorten the systems operational life as well as kill the important microbes. In high volumes animal and vegetable derived fat, oil, and grease (cooking oil, fat poured off cooked meat, etc.) can cause problems. It can block your drains and also take the microbes a long time to "eat" this material.
