ABSTRACT:
An apparatus for purifying waste water in an indoor environment is a container for holding the waste water to be treated together with at least one liner for receiving and holding an individual removable pot in which grows a house plant in a planting medium, typically expanded clay particles. The design of the container sets a constant interior water level. The support for the pots and the design of the pots then established the depth into this water level to which the growing medium and root structure of the chosen purification plants is immersed. INterlocking lips between the pot and the apparatus seal against the escape of odor producing gasses. The apparatus thus permits a wide variety of chosen house or office plants to be used for biological water purification, providing optimum growth conditions for any chosen plant.
