The effect of adsorbent dose, stirring speed, contact time, pH, initial Cu II) concentration and temperature was investigated.
The influences from test parameters such as scratch speed, contact geometry and load on the deformation response were examined.
The size of the samples was determined considering comparable speed, contact pressure, temperature and geometrical proportions to full-scale systems.
The effect of pH, temperature, agitation speed, contact time and initial metal ion concentration on the removal of Cr (VI) was determined.
The amount of biosorbent was varied from 0.50 to 5.00 g in 100 mL dye solution, while all the other variables such as pH, agitation speed, contact time, and temperature were kept constant.
Numerical factors (dispense volume, doctor blade speed, contact time between doctor blade, and coating materials) and categorical factors (doctor blade movement, pattern of drops, and number of drops for each patch) were used as input variables.
A detailed sensitivity analysis (involving viscosity, impeller speed, contact angle and liquid spray rate) has also been conducted in order to study the influence of the process parameters on the final granule properties.
Various operating variables (pH, adsorbent dose, initial fluoride concentration, agitation speed, contact time and temperature) and their combined effect on removal of fluoride was assessed by using computerise software model known as Response Surface Methodology (RSM) based on Box-Behnken design (BBD).
Cell speed, contact time and repolarisation were analysed as previously described (Kadir et al., 2011).
As a validation of the experimental method, a measure of the wear occurring during high-speed contacts have been performed.
