Ahlstrom MC Ozone Bleach Technology

Ozone pre-oxidation to the degradation technology research of MC-LR

Ozone pre-oxidation can effectively degrade MC-LR, 2mg / L ozone for MC-LR removal efficiency of 65.28%. 2mg / L ozone for MC-LR removal efficiency reach to 65.28%. Ozone also has a better removal effect for turbidity and UV254 , 4mg / L ozone for UV254 and turbidity removal efficiency are 50% and 59.38%. But ozone removal efficiency of TOC and CODMn was poor, 3mg / L ozone for TOC and CODMn re...

Don't bleach chaotic data.

A common first step in time series signal analysis involves digitally filtering the data to remove linear correlations. The residual data is spectrally white (it is "bleached"), but in principle retains the nonlinear structure of the original time series. It is well known that simple linear autocorrelation can give rise to spurious results in algorithms for estimating nonlinear invariants, such...

Ozone in the Advancement of Drinking Water Treatment Technology

Water and air ozone treatment as an alternative sanitizing technology

AIMS We investigated the effectiveness of ozone (aqueous and gaseous) treatment as an alternative sanitizing technology to common conventional disinfectants in reducing the microbial contamination of both water and air. METHODS Ozone was added for 20 minutes to a well-defined volume of water and air by the system named "Ozonomatic®". The effectiveness of ozonation was determined by counting C...
