How to dewater a construction site? The method you pick really depends on the unique blend of geology and hydrology at your site.
The differences identified between EPS removal and dewatering can be attributed to the different sources of sludge used, from different sewage treatments and treating effluents with complex and unique compositions, to using digested and undigested sludge, which considerably affects the potential for dewatering and the EPS extraction …
This paper describes a cost-effective method for phosphorus removal from reject water of sludge dewatering process by using supernatant from sludge lime stabilization (SLS) processes, which are extensively used in China.
Alternatively phosphorus can be recovered from the liquid phase after dewatering. In the case of EMBR facilities, phosphate is taken up under aerobic conditions and released again under anoxic conditions, with a high concentration of dissolved phosphate being obtained after anaerobic digestion or in the fermented return activated …
With the weak bonding of phosphorus to aluminum or iron, the primary method of trapping P is through coagulation. Coagulation involves neutralizing charges to form a gelatinous …
Florida phosphate clays contained in phosphate slimes are electro-sensitive. Accordingly, some electro-dewatering methods have been tested for the separation of water from the phosphate slime but these methods have not proved economical. Generally, these methods were based on theories of electrophoresis or electroosmosis.
This best practice guide to dewatering excavations on construction sites will help you avoid fines and delays and keep costs to a minimum.
The advanced anaerobic digestion process enhances sludge resource utilization. However, thermal hydrolysis pretreatment of anaerobically digested sludge reduces dewatering efficiency due to excessive organic matter decomposition. This necessitates significant time and effort for sludge conditioning in wastewater treatment …
The research described includes early dewatering experiments, fundamental studies of clays and of flocculation, and minor dewatering techniques such as freeze-thaw methods, the ANDCO process, moving screens, sand wick, crust development, and overburden pumping. Some methods that are currently being evaluated are described.
There are many considerations when determining the best dewatering method for a construction project. Variables such as the ground water table, the job site's soil makeup, and the scope of the work being performed are all considered when choosing the most effective method. According to MWI Pump's Steven von Gontard, who has …

EBPR enables PAOs to release phosphorus in the anaerobic stage and uptake phosphorus in excess in the aerobic stage to achieve phosphorus removal by …
Dewatering is a term to describe the removal of groundwater or surface water from for example a construction site. In construction the water is pumped from wells or sumps to temporarily lower the groundwater levels, to allow excavation in dry and stable conditions below natural groundwater level. ... Phosphate fertilizers ... Dewatering methods ...
Developing technology for dewatering phosphatic clays also is described, including the Bureau of Mines rotary trommel method and the Gardinier process. FIPR Publication No. 02-017-022 State-of-the-Art of Phosphatic Clay Dewatering and Disposal Techniques.
A dewatering method using PEO as a flocculant has been successfully used to dewater bentonite clay waste, coal-clay waste, and phosphate clay waste. In field tests, phosphate clay waste has been dewatered from 2.5 …
