Correlation of wood-based components and dewatering properties of waste activated sludge from pulp and paper industry
Large amounts of wet sludge are produced annually in municipal and industrial wastewater treatment. Already in pulp and paper industry, more than ten million tons of primary sludge, waste activated sludge, and de-inking sludge is generated. Waste activated sludge contains large quantities of bound water, which is difficult to dewater. Low water content would be a matter of high calorific value in ...

Speciation of heavy metals in electroplating industry sludge and wastewater residue using inductively coupled plasma
Abstract: The speciation of metals in environmental samples is a critical factor in assessing the potential environmental impacts, before their disposal. The distribution and speciation of toxic heavy metals in plating wastewater residues and sludge was investigated for four samples using sequential extraction method. Tessier method was used to fractionate the metal content into exchangeable, ...

Acid Mine Drain (AMD) treatment to achieve very low residual heavy metal concentrations
Abstract Mount Emmons mine wastewater treatment plant currently treats on average around 450,000 gallons per day of acid mine drain (AMD) water collected into several collection ponds. The plant uses standard lime hydroxide precipitation process at pH 10.7 to precipitate heavy metals and remove AMD contaminants with the subsequent flocculation - dissolved air flotation (DAF) and sand filtration. ...

Processing Wastewater Sludge Using Dewatering Containers
The relative cost of dewatering equipment varies widely and is directly related to the processing rate. For smaller utilities that need to dewater sludge in batches, dewatering containers are an alternative that can be relatively inexpensive and simple when compared to other technologies on the market. The most common type of dewatering container is based on a roll-off box design, although any ...

The development and application of centrifugal flotation systems in wastewater treatment
Abstract: Flotation as a wastewater treatment technique is designed to remove all particles generally encountered as very fine emulsions, suspended solids, and colloids from wastewater. Historically, Dissolved Air Flotation (DAF) has been used to achieve this removal. More recently, other flotation techniques such as induced air, electro, cavitational, and Centrifugal Flotation Systems (CFS) have ...

Agrior Project, Chaudière-Appalaches, Quebec, Canada
Compost Drying Application Agrior makes high value organic fertilizers by composting a mixture of animal manure and organic municipal and industrial wastewater treatment sludge. A DRY-REX low-temperature drying system was designed and installed at Agrior’s facility to dry the mixture into high-quality compost. The low-temperature process results in the drying of the manure with minimal ...

Towards a complete recycling of phosphorus in wastewater treatment – options in Germany
Global reserves of mineral phosphorus are finite and the recycling of phosphorus from wastewater, a significant sink for phosphorus, can contribute to a more sustainable use. In Germany, Switzerland, and the Netherlands, an increasing percentage of municipal sewage sludge is incinerated and the contained phosphorus is lost. This paper reviews current technologies and shows that a complete ...

NSW Tannery benefits from highly efficient chrome removal process and a very dry sludge - Case study
NCMC (Northern Cooperative Meat Company) engaged Hydroflux Industrial to design and install a new treatment plant to remove Chrome from wastewater originating from the on site tannery in Casino, NSW. Located on the same site as the abattoir all hides are received immediately after slaughter and put directly into the chrome tanning process. The raw wastewater from the factory contains up to 300 ...
