Phyto-dewatering of sewage sludge using Panicum repens L.
Experiments in the field environment have been conducted to study the growth of Panicum repens L., an aquatic plant, in the sewage sludge matrix. The experiments were also carried out to investigate the ability of this plant to dewater sewage sludge to increase the capacity of conventional drying beds. In addition, the ability of Panicum repens L. to reduce the sludge contents of certain ...

Manufacturing ceramic bricks with polyaluminum chloride (PAC) sludge from a water treatment plant
The objective of this research work is to assess the viability of manufacturing ceramic bricks with sludge from a water treatment plant (WTP) for use in real-world applications. Sludge was collected from settling tanks at the Bolonha WTP, which is located in Belém, capital of the state of Pará, Brazil. After dewatering in drainage beds, sludge was added to the clay at a local ...

Pyrobustor - A Proven,Small-Scale, Biosolids-to-Energy Solution
27 municipalities in southern Germany set up a special-purpose entity called KSV GmbH for the specific purpose of disposing regional sewage sludge. The goals of this project were two-fold; eliminate the expensive cost of transporting sewage sludge over long distances and avoid incalculable costs by outsourcing sludge disposal. To achieve this, KSV GmbH installed the Pyrobustor® at the ...

Case Study | Techase 80% Sludge Feeding Application at Lingbi WWTP
This time, let me take you to Lingbi, Anhui, China to know more about Techase “80% sludge feeding directly” process. Conventional deep sludge dewatering projects generally need to control sludge MC at about 95%, and then start the final squeezing stage for deep dewatering. In this way, some sludge with 80% MC has to be diluted first which is more complex and expensive. Techase has ...

Effect of daylight on regrowth of bacteria in anaerobically digested sludge
This study investigated the regrowth of total coliform, Salmonella, and Clostridium perfringens in anaerobically digested sludge after centrifuge dewatering in the presence and absence of daylight. Sludge cake and centrate samples were collected from a treatment plant, and half of the samples was stored in daylight and the other half was stored in dark for three weeks. The bacteria levels in the ...
