Ft. Pierce WWTF - Case study
EXECUTIVE SUMMARY In September of 2014, a CleanB® system was installed at the Ft. Pierce WWTF. Before the CleanB® installation, the plant wasted to a DAF unit for thickening and held sludge in an aerobic holding tank prior to contract dewatering and landfill disposition. After installation of the CleanB® system, the plant started wasting directly from the clarifier to the CleanB® ...

Pulp & Paper Sludge Dewatering - Stora Enso, Niagara Mill, Wisconsin - Case Study
The Stora Enso, Niagara Mill, was established in 1889. Niagara Mill uses 7,500,000 gallons per day of water from the river to make pulp & paper. The removal of the solids is accomplished by treating it with alum, then a flocculent, allowing the solids to settle out in a 2,000,000 gallon setting tank system. This tank requires yearly cleaning to ensure quality water for the paper making ...

Biosolids Dewatering - A Hygienic, Cost-Efficient Waste Disposal Method
The proper disposal of liquid waste is a very important. Liquid waste is made by every business and household, and it can be produced in very large amounts. Because liquid waste often contains a lot of toxins and chemicals, it is highly important that it is not allowed to leak out into local lakes, streams, or aquafers. With the process of biosolids dewatering, liquid sludge can be greatly ...

Sludge dewatering in Circular Economy
The change of mentality to a circular economy has revealed the importance of reusing and energy recovery from sludge as secondary raw material Circular economy and re-use of waste materials Nowadays, the rise of the circular economy and the progressive abandon of the linear economy (throwaway culture), the secondary raw materials receive a special importance. Theenergy recovery and the re-use of ...

Sustainable sludge handling for the 21st Century
Purification of municipal and industrial waste waters leads to the generation of a residue-called “excess sludge”. This material when mechanically dewatered is typically 75-90% water. The balance of the dewatered sludge consists of organic compounds (solid waste, biomass) and inert materials (sand, salts, and metals). These sludges have been to date dehydrated to reduce the aqueous fraction ...

What is Sludge Dewatering?
What Is Sludge vs. Sludge Cake? Sludge dewatering is a process in which a sludge slurry (sludge) is made more solid by removing water from its contents to form a sludge cake. A wide variety of municipal and industrial processes will create sludge cake after it is dewatered using various presses to form higher solids content versus a watery sludge slurry. While dewatering does not in itself treat ...

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 ...
