water is subjected to two different purification processes, namely separation by means of at least one selective permeability membrane followed by deionizationdoi:US20040178146 A1It also relates to a tangential filtration module suitable for the above kind of system.Yves Gaignet...
8. Reverse Osmosis. This is a system of water purification which allowspre-filtered water to be forced through a semi-permeable membrane to separateimpurities from our drinking water. However, this membrane allows only certainmolecules to pass through providing the water pressure is exactly constant....
There are a number of detailed processes completed when purifying water. With each treatment contaminants in the water are further reduced and the level of purity increased. The duration of this process depends on the level of impurity before beginning the purification process. Once all unwanted con...
Four wetland plant species(Acorus calamus,Typha orientalis,Lemna minor,Ceratophyllum demersum) were grown to compare the purification efficiency of wetland plant species alone and in combination on two eutrophic water bodies,high concentration sewage(influent) and low concentration sewage(effluent) in a...
Polymeric membranes are currently adopted in water purification processes, such as reverse osmosis (RO) and membrane distillation (MD). This latter techniq... GA Mannella,VL Carrubba,V Brucato - 《Journal of Applied Polymer Science》 被引量: 13发表: 2011年 Characterization and performance of na...
The efficiency of water purification by two different mollusks was determined under same algae biomass in 24 hours.The results indicated that there were twice higher elimination efficiency of suspended substances in Cristaria plicata than that in Bithynia fuchsiana,but Bithynia fuchsiana had as twice...

The design of experiment is a very useful method in finding the optimal purification conditions. This method also can be used to analyse the influence of different parameters involved in the purification process and to evaluate the interactions between the parameters (Rosa et al.2010). Furthermore...

The kinetics of biogas purification by the KOH solution has a fast and complete removal of CO 2 with a large increase in the calorific value of the purified biogas of order 2.7kWh/m 3 compared other types of purification substrate. But this type of purification has a low speed of disappeara...
