One hundred and five samples of bottled drinking water belonging to 30 different brands, collected from six different states of India have been analysed for total heterotrophic bacterial (THB) load and coliforms. Almost all bottlers used multiple treatment procedures such as microfiltration, reverse osmosis and ozonization to treat the water. Around 40% of the samples exceeded the limit of 100 ...

Ozone (O3) has been widely used for water and wastewater treatment due to its strong oxidation ability, however, the utilization efficiency of O3 is constrained by low solubility short half-life during process. Thereby, an integrated approach using novel nanobubble technology ozone method was studied in order enhance ozonization ammonia. Artificial (AW) with initial concentration 1600 mg/L ammo...

Xxomnuoehemical Studies on the Tryptophan-modified 'ýobrotoxin The two-dimensional structure of cobrotoxin has recently been established and permits a study of structure-activi~ty i-elatioziships. Preceding studies on the chemical modification of c:Dbrotoxin nuggested that either the intact Tyr-25, Lys-47, or* G'>1-2*: is essential for full activity of the toxin.
