Bio-enhanced activated carbon filter with immobilized microorganisms for removing organic pollutants in the Songhua River
Five dominant microorganisms including four kinds of Pseudomonas and one kind of Bacillus were isolated from the Songhua River. The organic pollutants removal potential and community composition of these five dominant microorganisms immobilized on activated carbon filter, which is called the bio-enhanced activated carbon filter (BEAC), were investigated to compare with the naturally formed ...

MBR Based treatment of tractor manufacturing wastewater
Abstract Kubota corporation has recently built new tractor manufacturing plant in Jefferson Georgia. CWT and Kubota agreed to design, pilot test and build a system for full water reuse of up to 75% of produced wastewater. Wastewater is very complex and contains complexed heavy metals, fine suspended solids, emulsified oils, grease, strong degreasing agents, nutrients (nitrogen and phosphorous) ...

Activated carbon for the removal of pharmaceutical residues from treated wastewater
Pharmaceutical residues, which pass naturally through the human body into sewage, are in many cases virtually unaffected by conventional wastewater treatment. Accumulated in the environment, however, they can significantly impact aquatic life. The present study indicates that many pharmaceutical residues found in wastewater can be removed with activated carbon in a cost-efficient system that ...

The use of potassium permanganate, ozone and associated coupled processes for odor removal in drinking water: bench and pilot scale tests
Bench and pilot scale experiments were conducted to investigate and compare the preoxidation effects of potassium permanganate (KMnO4) and ozone (O3) for odor removal in drinking water. The effects of dosage, contact time, pH, as well as couple treatment with a granular activated carbon (GAC) filter were examined using bench experiments, while the effects of KMnO4 dosing points and a ...

Wichita ASR Project, KS – Bromate Control Case Study
The City of Wichita’s Aquifer Storage Recovery (ASR) Project involves seasonal operation of a UF/disinfection plant to treat storm water from the Little Arkansas River for groundwater recharge. Constituents of concern included atrazine, viruses, turbidity, total organic carbon (TOC), and bromate. Each of these constituents had a potential significant impact on possible treatment processes. ...
