A mathematical model describing continuous microbial culture and harvest in a chemostat,
incorporating a control strategy and defined by impulsive differential equations, is presented …

An integrated unit to purify and reuse domestic laundry wastewater consisting of
coagulation, sand filtration, carbon adsorption, and ultrafiltration process is developed …

Research findings of the past few decades on the cultivation of microalgae for biodiesel
production from laboratory to pilot scale microalgal cultivation have translated into empirical …

In this study, an organic dye sensitizer derived from blackberry fruits was employed, and the
influence of aluminium sulphate, Al 2 (SO 4) 3· H 2 O (alum) as a bi-functional (acidification …

The removal of dye by flocculation was investigated for two types of sludge (mixture of
organic and inorganic components) and for “pure” dyes with polycations in comparison with …

Adsorption of anionic dyes on the cross-linked with epichlorohydrin starches containing
quaternary ammonium groups (CCS) was investigated and compared with that of modified …

To improve the dispersion capacity of poly (carboxylate ether)(PCE) in clay-containing
cement paste, lignosulfonate (LS) was quaternized with 3-chloro-2-hydroxypropyl …

Polycarboxylate superplasticizer (PCE) is widely used in concrete, but the clay content in the
aggregate is increasing at present, which seriously weakens the dispersing function of PCE …

For weak polyelectrolytes, the interplay between pH, solvent properties, and polymer
structure affects the amount of charges, their distribution, and hence their conformations via …

Epichlorohydrin-dimethylamine polymers with different intrinsic viscosity (η) and cationicity
(τ) were synthesized. The flocculation performance and mechanism of these polymers in the …
