The ability of green algal biomass of Ulva sp. to biosorb Cr(III) and Mn(II) from single‐ and binary‐ solute systems was investigated. Experimental results showed that pH 4.5 resulted in highest metal uptake by Ulva sp. biomass. Determined levels of maximum biosorption capacities were 2.89 and 1.07 mmol g−1 for Cr(III) and Mn(II), respectively, during single‐solute systems. Isotherms were modeled...
Growing population and rapid economic development lead to increasing pollution loading and lowering water quality. Protection of water environments is our glory target; The key strategy is: combining management of the land-water system in catchment and realizing the quasi-non-pollution release in an as small as possible catchment area.”; developing the high technology for realizing this target in...
Improper management of sanitary landfill will become a huge problem to the environment. The main pollution occur by sanitary landfill is the generation of leachate which will affect groundwater, ecosystem and also human health because of the highly content of heavy metal. The removal of heavy metal in leachate has become important to maintain water quality standard before it will discharge to environment...
A new process of enhanced dissolved air floatation (DAF) by pulsed high voltage discharge was studied in this paper. With high voltage discharges, removal rate of some normal water quality indexes were better improved, such as UV254 and CODMn from 0.145 to 0.142 and from 6.2 mg/L to 5.8 mg/L. The turbidity of water after treated with pulsed high voltage discharges was larger than that without discharges...
