Paulus Johannes Maria Maas from Netherlands [5] and Nobuyuki Tanaka from Japan, both experts in the taxonomy of genus Canna, assign different classifications for this species. Dr Maas considers C. coccinea to be a synonym of C. indica L., however, Dr Tanaka's DNA-based approach shows that species in the Canna indica complex can be clearly ...
Rhizofiltration is a contamination treatment method that may be conducted in situ, with plants being grown directly in the contaminated water body or ex situ, where plants are grown off-site and later introduced to the contaminated water body. [8]
The following list is based on the Taxonomic revision of the family Cannaceae in the New World and Asia, by Tanaka [4] and the proposal to conserve the name Canna tuerckheimii over C. latifolia.
Sewage treatment plants mix these organisms as activated sludge or circulate water past organisms living on trickling filters or rotating biological contactors. [ 5 ] Aquatic vegetation may provide similar surface habitat for purifying bacteria, protozoa, and rotifers in a pond or marsh setting; although water circulation is often less effective.
The RBC process allows the wastewater to come in contact with a biological film in order to remove pollutants in the wastewater before discharge of the treated wastewater to the environment, usually a body of water (river, lake or ocean). A rotating biological contactor is a type of secondary (biological) treatment process.

This contaminated water can be disposed of, along with the sludge from the sedimentation basin, or it can be recycled by mixing with the raw water entering the plant although this is often considered poor practice since it re-introduces an elevated concentration of bacteria into the raw water. Some water treatment plants employ pressure filters.
