With the rapid development of urbanization in China, eutrophication or black stink urban rivers has become a critical environmental problem. As research hotspot wastewater purification, biofilm technology shortcomings, such as insufficient carbon sources for denitrification. This study used Biofilm Denitrification Batch Reactor (BDBR) system constructed using reed biochar source required denitr...

The active substances in the drug can cause various negative effects by accumulating ecosystem. Many of medications are resistant to biodegradation, which given recipient media conventional wastewater treatment plants, partially or no purification. In this study, 13 different pharmaceutical compounds belonging classes anti-depressants, antiepileptics, anti-inflammatories, beta-blockers, licodai...

The increase in population demands for industrialization and urbanization which led to the introduction of novel hazardous chemicals our environment. most significant parts these harmful substances found water bodies remain background, causing a health risk humans animals. It is critical remove toxic from wastewater keep cleaner greener Hence, treatment challenging area days manage liquid waste...

The article presents the features of cascade phyto-treatment facilities, bio plateau with an open water mirror. Such structures are similar to natural wetland objects. plant species on cascades and their effect in post-treatment wastewater considered. Natural biological treatment algae roots is one most effective methods treatment. This method allows you clean polluted without harming environme...

The purification of terephthalic acid recovered from an alkali-reduction wastewater by reactive crystallization was investigated. crude reacted with sodium hydroxide solution to form a salt disodium terephthalate, then acidified sulfuric get the higher purity. Effects time, pH, concentration, and flow rate secondary feed solutions, temperature, stirring on Crystal Size Distribution (CSD) precip...

Abstract The canteen and laboratory of every academic organization need a lot clean water, it generates equivalent amount wastewater hour which is neither purified nor reused. Due to water scarcity, the recycling reusing become very essential. present study describes simple cost-effective method for design small-scale treatment plant purification generated by household, an institute. current ex...
