AbstractDuring the modern history the ability of plant roots to consolidate and strengthen the soil was exploited twice in France: once in1867 by Joseph Monier who created the reinforced concrete, and then in 1962 by Henry Vidal who created structured soils.The paper presents the some results obtained on the ecological protection of floodplain in major riverbeds. The aerodynamic modeling represents an efficient, economic and easy way to work with. The main condition of successful experiments is ...

AbstractHollow fiber polyacrylonitrile membranes with three different MWCOs (i.e. 6, 13, 50 kDa) have been tested for dead-end ultrafiltration of a combined refinery and petrochemical secondary effluent. The effluent treatment envisaged further recycling as cooling water make-up following an ultrafiltration/reverse osmosis advanced treatment scheme. Criteria for ultrafiltration evaluation included flux restoration by backwashing, turbidity removal efficiency and water recovery. The membranes cou...

AbstractA new environmentally friendly lignosulfonate-based glue (LSG), which represents the lignin-containing interpolymer complex, has been developed for structuring sandy soils. It has been found that the changes in the LSG composition result in a change in its rheological properties, which are associated with the LSG binding ability and, thereby, have to influence the fractional composition and properties of the created soil aggregates. ...

This paper describes the preparation and use of a low cost biosorbent made of castor leaves for the extraction of Cu(II) from an aqueous medium. The biosorbent was characterized by Fourier transform infrared spectroscopy (FTIR), surface area and pore diameter measurements. The results showed absorption bands of carboxylic and amide groups at 1738 and 1540 cm-1, respectively, and the measured surface area was 1.3728 ± 0.0160 m2 g-1, with predominance of microporous < 10.51 Å. ...
