Sludge Blanket Level Articles on Environmental XPRT

Technical Focus: Sludge Blanket

Regardless of treatment process, sludge blanket control is an important aspect of any wastewater treatment plant, and correct monitoring and treatment of sludge is paramount for efficiency and cost control. Manual monitoring of sludge blanket levels is an occasional and often rushed method of control and can lead to inaccuracies being compounded over time, potentially leading to overspill into ...

Novel method for sludge blanket measurements

The most widely used methods for sludge blanket measurements are based on acoustic or optic principles. In operation, both methods are expensive and often maintenance-intensive. Therefore a novel, reliable and simple method for sludge blanket measurement is proposed. It is based on the differential pressure measurement in the sludge zone compared with the differential pressure in the clear water ...

Treatment of domestic wastewater using upflow anaerobic sludge blanket reactor

This paper presents the findings of the study on treatment of domestic wastewater using a laboratory scale Hybrid Upflow Anaerobic Sludge Blanket (HUASB) reactor. The reactor with a working volume of 5.9 L and plastic cut rings as packing media was operated at varying Hydraulic Retention Time (HRT) for a period of 110 days. While the COD removal varied from 75-86%, the BOD removal was in the ...

Full Scale Magnetic Ion Exchange Process Tested by Historically High DOC Levels

The Aireys Inlet Water Treatment Plant (WTP) is located about 150 kilometres from Melbourne on the Great Ocean Road. The WTP utilises a conventional upflow sludge blanket clarification process. The raw water source for this plant is characterised by high DOC levels. Despite operating in an enhanced coagulation mode sufficient DOC removal was not able to be achieved. This resulted in high ...

Flotation outperforms sedimentation and ultrafiltration for turbidity and NOM removal at the drinking water treatment plant of Kluizen

The drinking water plant of Kluizen treats surface water with high levels of organics and alkalinity. In the original plant, built in 1974, sludge blanket clarification followed by filtration was applied for floc removal. In 2008, the plant was extended with two additional treatment lines where flotation is used instead of sludge blanket clarification. Flotation-filtration proved to be very ...

Acid resistance of methanogenic bacteria in a two-stage anaerobic process treating high concentration methanol wastewater

In this study, the two-stage upflow anaerobic sludge blanket (UASB) system and batch experiments were employed to evaluate the performance of anaerobic digestion for the treatment of high concentration methanol wastewater. The acid resistance of granular sludge and methanogenic bacteria and their metabolizing activity were investigated. The results show that the pH of the first UASB changed from ...
