In Project WASTEC, an experimental Reverse Osmosis (RO) desalination system was developed. It serves as a platform for testing new technologies. For this system, we solved two problems, which are described in paper. Firstly, developed and investigated strategies scheduling chemical enhanced backwashing cleaning secondly, due to the nature of project, several technological developments with resp...

Abstract The quality of raw water in Surabaya is decreasing, and conventional treatment units are no longer efficient treating to become drinking water. Microfiltration membranes applied sedimentation can produce better results on limited land that uses a small number chemicals. material will be deposited the membrane’s surface throughout filtration process. deposition these materials cause fou...

Cell mechanical phenotype or 'mechanotype' is emerging as a valuable label-free biomarker. For example, marked changes in the viscoelastic characteristics of cells occur during malignant transformation and cancer progression. Here we describe a simple and scalable technique to measure cell mechanotype: this parallel microfiltration assay enables multiple samples to be simultaneously measured by...

Schistosomiasis is a parasitic disease affecting over 200 million people worldwide. This study reports the design and development of a microfiltration device for isolating schistosome eggs in urine for rapid diagnostics of urogenital schistosomiasis. The design of the device comprises a linear array of microfluidic traps to immobilize and separate schistosome eggs. Sequential loading of individ...

A laboratory-scale membrane filtration cell was constructed to enable direct microscopic observation of microbial cell deposition and release in cross-flow microfiltration. Initial deposition rates determined from microscopic images were interpreted through an interaction force model. Experimentally derived deposition rates and model calculations confirmed that initial cell and particle deposit...
