Nowadays‚ water pollution is a big problem in Vietnam and many researchers have been studying it. Accordingly‚ there are two main reasons of water pollution in Vietnam. The weakness in industrial wastewater management is the main cause of water pollution in Vietnam. Many industrial facilities use freshwater to carry away waste from their plants into canals‚ rivers‚ and lakes. Most of the enterprises don’t have any wastewater treatment system and many industrial zones don’t have a central wastewater

CHAPTER 6 PRETREATMENT AND CLEANING Pretreatment and cleaning are two independent processes that could also be related to each other at the same time. Such methods are crucial for seawater reverse osmosis for what they bring from cost and residence time reductions to the increase in the production quality. 6.1. Pretreatment Various pretreatment methods are used and they include: biofilter‚ subsurface intake systems‚ conventional treatment‚ biological activated carbon‚ and chlorine injection.

Field Trip Report in KFBG Background Information In order to learn more about the conservation of natural resources‚ a field trip was held on 30th October‚ 2013. It took place in Kadoorie Farm and Botanic Garden (KFBG). The field trip enables us to experience how to implement the conservation of natural resources‚ such as water and farming and helps explain what we have learnt in class. After going the fantastic field trip‚ I have learnt a lot from KFBG. That impressive knowledge is not only something

The increasing amount of inadequately treated industrial wastewater and non treatment of municipal wastewater has created huge demand for superior and cost effective equipments and technologies. The feeble treatment efficiencies of wastewater‚ rising awareness about environmental dilapidation‚ and greater water requirements represent abundant growth potential for the wastewater treatment equipment. The Indian wastewater treatment equipment observes increasing adoption of Membrane Bioreactors (MBRs)

Reverse Osmosis For Wastewater Recycling Reusing treated wastewater for beneficial purposes‚ such as agricultural and landscape irrigation‚ industrial processes‚ toilet flushing‚ or groundwater basin replenishment‚ is growing in response to environmental and economic concerns. One of the key factors involved in recycling wastewater treatment plant (WWTP) effluent for another use is the need to reduce total dissolved solids (TDS). This is often done by using a reverse osmosis (RO) system‚ which

I. INTRODUCTION This report aims to discuss and to enrich the reader ’s knowledge on the proper desludging and disposal of waste accumulated from septic tanks. The information gathered here is vital as it provides a culture of awareness to everyone on how wastewater is disposed of. Wastewater comes from everywhere; from our residences to our workplaces‚ even public places. Filipinos as we are‚ have been known to be hygienic yet we know little of what happens when our used water is flushed to the
