The aim of this research is to design a rainwater filtration system by using an activated carbon. The activated carbon had been act as one of the filter medium to filtrate the water. Three filters were design, namely Filter A, Filter B and Filter C, to determine the most effective filter that can be used in the study. To determine the effectiveness of the filter, seven parameters were measured that...
In this study, we have investigated the effect of pollutants removal of a vertical multilevel soil infiltration (VMSI) system on municipal wastewater treatment. The VMSI was of 30cm*20cm*50cm column, in which combined stuffing consisted of soil, quartz sand, active carbon and scrap irons were packed. As a result, VMSI system exhibited excellent removal efficiency with 91.7% of COD, 98.4% of NH4+--N,...
One of China largest river, Songhua River was polluted due to the explosion at a PetroChina factory in Jilin province in 2005. A full scale test was carried out to investigate the removal of nitrobenzene in the raw water from polluted Songhua River. The removal and control effects of nitrobenzene by using Powered Activated Carbon (PAC) absorption and Granular Activated Carbon (GAC) filtration as emergent...
The objective of this study is to further evaluate the relationship between removal effect of dissolved organic pollutants (DOC) and their characteristics (biodegradability, adsorbability and molecular size distribution) in different running stage of BAC filter. The experimental results showed that during early period of operation, BAC filter mainly removed adsorbable DOC (that is ADOC), but after...
Experiments on adsorption for phosphorus by activated carbon, zeolite and ceramisite were conducted. The results show that adsorption capacity order of three filter media from high to low is activated carbon, zeolite and ceramisite. Influential factors which affect the adsorption capacity were surveyed. According to the analysis, the first factor is that surface isoelectric point pH of activated carbon...
Phosphorus sludge is one kind of harmful waste from the yellow phosphorus industrial production. It can cause serious pollution to the environment. It was used to be a kind of raw material to produce sodium hypophosphite. However, phosphorus sludge is hard to decompose, so dispersing agent has to be added to increase the productive rate of sodium hypophosphite. Four kinds of dispersing agents are...
The zeolite was disposed by the means of dynamic activation with different activators. A new combined process of zeolite and Granular Activated Carbon (GAC) has been developed, which removed the organic pollutant in Drinking Water deeply. Through the static and dynamic adsorption experiment of zeolite-activated carbon, the main factors of experiment were analyzed thoroughly; the optimal proportion...
Catalytic ozonation/biological activated carbon process was applied for advanced drinking water treatment in this study. The results showed that with the ozone dosage of 2.0mg/L, the removal of CODMn, TOC and UV254 in catalytic ozonation unit was 24.6%, 15.9% and 59.8%, and increased to 40%, 16% and 68% respectively after being treated by BAC. The catalytic ozonation unit contributed to more than...
