removal of sand, gravel, cinders, coffee grounds, small stones, cigarette filter tips,
logs, cans, and other large-sized unwanted materials from raw wastewater),
(b) primary flotation clarification for removing mainly total suspended solids
from preliminary effluent, (c) secondary biological treatment units (such as
activated sludge aeration or equivalent plus secondary flotation clarification) for
removing dissolved organic/inorganic pollutants from primary effluent, and
(d) tertiary treatment plant units (i.e., filtration, granular activated carbon adsorption, ion exchange, oxidation, nitrification, denitrification, and/or disinfection) for
final polishing the secondary effluent in order to meet the effluent discharge
standards.
Innovative physicochemical flotation wastewater treatment system It includes
(a) preliminary treatment units (i.e., screen, comminutor, grit chamber, etc., for
removal of sand, gravel, cinders, coffee grounds, small stones, cigarette filter tips,
logs, cans, and other large-sized unwanted materials from raw wastewater),
(b) primary flotation clarification for removing mainly total suspended solids
from preliminary effluent, (c) secondary physicochemical treatment units (such as
chemical precipitation/coagulation or equivalent plus secondary flotation clarification) for removing dissolved organic/inorganic pollutants from primary effluent, and (d) tertiary treatment plant units (i.e., filtration, granular activated carbon
adsorption, ion exchange, oxidation, nitrification, denitrification, and/or disinfection) for final polishing the secondary effluent in order to meet the effluent
discharge standards. In the nitrification and denitrification steps, only tertiary
flotation clarification will be used for solid-water separation.
Innovative physicochemical flotation-membrane wastewater treatment
system It includes (a) preliminary treatment units (i.e., screen, comminutor,
grit chamber etc. for removal of sand, gravel, cinders, coffee grounds, small
stones, cigarette filter tips, logs, cans, and other large-sized unwanted materials
from raw wastewater), (b) primary flotation clarification for removing mainly
total suspended solids from preliminary effluent, (c) secondary physicochemical
treatment units (such as chemical precipitation/coagulation or equivalent plus
secondary membrane clarification) for removing dissolved organic/inorganic
pollutants from primary effluent, and (d) tertiary treatment plant units (i.e.,
filtration, granular activated carbon adsorption, ion exchange, oxidation, nitrification, denitrification, and/or disinfection) for final polishing the secondary
effluent in order to meet the effluent discharge standards. In the nitrification and
denitrification steps, only tertiary membrane clarification will be used for solidwater separation.
Insecticide It is a substance used for killing insects.
Intergovernmental Panel on climate Change (IPCC) The IPCC was established
jointly by the United Nations Environment Programme and the World Meteorological Organization in 1988. The purpose of the IPCC is to assess information in
the scientific and technical literature related to all significant components of the
issue of climate change. The IPCC draws upon hundreds of the world’s expert
scientists as authors and thousands as expert reviewers. Leading experts on
