An alternative CO 2 sequestration method is carbonation of cement-based materials. The fundamentals of this concept is that cement and its hydration products are reactive with CO 2.The CO2 sequestration is realized by intentionally supplying CO 2 to the cement-based composite during the manufacturing process, which includes (as is …
A comparatively optimization of dosages of oxidation agents based on volatile solids and dry solids content in dewatering of sewage sludge Article Full-text available
Reasonable dewatering rates continue for some time, then the rate is very low with little gained in percent moisture reduction over long periods of time. When the slower dewatering rate period is reached, the filtration is stopped at an acceptable level to discharge the cake and allow another cycle to begin. 5.

The main objectives of this paper are: (1) to calculate hydrogeologic parameters of aquifer based on the pumping tests; (2) to simulate groundwater level at different depths of underground continuous concrete wall during dewatering; (3) to calculate the maximum land subsidence at different distances away from the foundation …
Mine dewatering is a production critical function; inflow of waters needs to be removed to maintain a safe production environment. In order to ensure redundancy, the pumping system must include spare pumps and parts. In a three-unit system, any two pumps need to be able to provide the maximum inflow.
A paste backfill system facilitates the use of a mechanized undercut-and-fill mining system which increases safety, reduces dilution, and can be used with nearly any orebody shape. A paste backfill …

Dewatering is the process of removing water from solid material or soil by wet classification, centrifugation, filtration, or similar solid-liquid separation processes. This process is often used in the construction industry to remove water from hardened concrete, soil, or other materials and enable the reuse of construction materials.

The operation of dewatering is performed in two stages. First, the bulk of the water is removed in a thickener, from which the concentrate is discharged as a thick pulp ; as a rule the underflow contains 55 to 65% of solids, while 70 to 80% of the original water is recovered in the overflow as a clear liquid. The thickened pulp is then sent to ...
