Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

The particles surface charge is classified among the essential criteria in the coagulation and flocculation treatment. Colloidal particles in suspensions are generally dispersed, electrically charged and do not settle by the gravity due to its stability and repulsion. Good settling can be achieved by disrupting the surface charge in the suspension of unstable particles. The zeta potential (ZP) is an indicator or criterion that represents the electrostatic interactions in a particle dispersion and is a measure of particle surface charges. This paper evaluated the mechanism and the effect of pH, ZP and particle size of colloids on the reduction of colour and suspended solids (SS) in leachate by the positive charge coagulant, Tin tetrachloride (SnCl4). A range of experiments on coagulation and flocculation was undertaken using the standard jar test with ZP measurement. It was found that the addition of positively charged SnCl4 as coagulant increased the leachate surface charge. The maximum ZP before the addition of SnCl4 was -22.4 mV at pH 11, and the surface charge of leachate was closed to the point of zero charges at pH 8 with -0.4 mV after the coagulant was added. Highest colour and SS performance were observed at optimum pH 8 with reductions of 98.9% and 100%, respectively. The reduction of repulsive forces at this pH promoted the collision of particles and thus made the aggregation possible
To date, many academic studies have been conducted on the topic of Universal Design (UD). Besides, several design guidelines have been developed to inform policy and guide architects to design buildings which can accommodate people with various abilities and disabilities, and different attributes as well. Though, it is unclear whether the existing UD guidelines are able to assist architects in designing shopping malls based on UD principles. Thus, this present study systematically assessed the capability of UD guidelines to address the shopping mall design indicators. This study also determined the significance of these indicators in UD guidelines. The findings showed that the “stairs” and “architectural wayfinding” were the most significant (significance score = 2.67) and least significant (significance score = 0.33) shopping mall design indicators, respectively, in UD guidelines. In addition, the most capable and least capable UD guidelines in addressing the shopping mall design criteria were the Centre for Excellence in Universal Design (capability score = 33) and the CEN/CENELEC (capability score = 4), respectively. The findings of this study can help architects to select the best UD guideline for designing the shopping malls which follow the UD principles. In addition, more comprehensive UD guidelines can be proposed in the future based on the findings of this study
