Application of waterworks sludge in wastewater treatment plants

Application of waterworks sludge in wastewater treatment plants

The potential for reuse of iron-rich sludge from waterworks as a replacement for commercial iron salts in wastewater treatment was investigated using acidic and anaerobic dissolution. The acidic dissolution of waterworks sludge both in sulphuric acid and acidic products such as flue gas washing water and commercial iron solution was successful in dissolving the iron from waterworks sludge. The ...

Co-treatment of Faecal Sludge in Municipal Wastewater Treatment Plants

Tetracycline resistance genes in activated sludge wastewater treatment plants.

The development and proliferation of antibiotic resistance in pathogenic, commensal, and environmental microorganisms is a major public health concern. The extent to which human activities contribute to the maintenance of environmental reservoirs of antibiotic resistance is poorly understood. In the current study, wastewater treatment plants (WWTPs) were investigated as possible sources of tetr...

Pollution potential and ecological risk of heavy metals in municipal wastewater treatment plants sludge

Background and Objective: Application of sewage sludge contaminated with heavy metals may cause health and ecological concern. Ecological risk and heavy metals content of sewage sludge from wastewater treatment plants of East Azerbaijan province were evaluated in the present study. Materials and Methods: Nine composite samples were taken and analyzed for heavy metals. The geo-accumulation inde...

Application of sludge from urban wastewater treatment plants in road's embankments.

While different kinds of compost have been tested for highway revegetation, sewage sludge has only been used for agricultural purposes. In this work, its application for helping vegetation establishment on roads embankments is studied. Testing areas measuring 4x5m were constructed on a new highway embankment in an arid location. Several variables are analyzed: side slope (2); sludge dosage (4);...
