This work demonstrated the potential of US for mitigating membrane fouling. However, the integration of the US transducers within the membrane system will be a major challenge for the application of US in membrane cleaning. It is more appropriate that US is used as pre-treatment to the membrane system, the transducers can be placed prior to the coagulant feed line. Further work on the determination of the detailed mechanisms associated with enhancing coagulation would enable optimisation of the system with regard to process, cost and energy efficiency.

The study provides a comprehensive picture of the animal feed sector in Vietnam (both supply and demand side) upon data collected from 2 main surveys: feed mill survey investigating the supply side and producer survey investigating the demand side. The results show that, on the supply side, SMEs appear to have less competitiveness than large ones. That is reflected in some aspects such as higher production costs per kg output, using more labor, limited quality control, limited access to capital and land, and many small enterprises have losses.

Dams and particle separation is important in the process of harvesting rice (rice; wheat) and energy intensive. There have been many studies on various parts of the dam to improve your drum beats combine harvesters were introduced in recent years. Research division beating drums beating two types of tangential to the direction tangential feed was made in 2007 with the aim of: increasing particle separation distribution of the dam, the dam reduced energy costs, reduce the impact split ...
