You can use lime to stabilize industrial residual sludge, for sludge dredging and to treat urban biosolids before agricultural re-use or incineration. Helping coagulation, lime makes sludge easier to handle, prevents fermentation, limits odors, eliminates pathogens and holds metallic ions in an insoluble form.

The unwritten rule when evaluating the suitability of water for use in concrete has typically been, "If you can drink it, you can make concrete with it." Many within the industry still have this perception and it is the reason why some customers may not allow the use of process water for batching, even though industry evaluations led to a ...

The first step is to dry the wet sludge cake before grinding and sieving it to produce domestic waste sludge powder. This powder is then mixed with cement. The researchers have experimented with 3, 5, 7, 10 and 15% sludge powder proportions in a cement to produce normal strength and two higher strength grades of concrete.

Each riser pipe is situated at the intersection of a v-plow and receives a continuous feed of sludge that returns to a sludge collection box near the center of the clarifier. This design is intended for secondary, biological, or flocculated solids which are more fluidized and have lower densities than primary wastewater and heavy industrial sludge.

Sludge is a residual, semi-solid by-product left from industrial or refining processes. It is a separated solid suspended in a liquid, typically containing major quantities of interstitial water between its solid particles. This material can be dried to cut its volume and reduce most of the moisture content of the biosolids present in the sludge.

Activated sludge (AS) is a process dealing with the treatment of sewage and industrial wastewaters and developed around 1912-1914. There is a large varity of design, however, in principle all AS consist of three main components: an aeration tank, which serves as bio reactor; a settling tank ("final clarifier") for seperation of AS solids and treated waste water; a return

Sludge is an unavoidable side-effect coming about because of wastewater treatment. Dewatered sludge is ordinarily arranged off by spreading on the land or via landfilling. For urbanized zones, sludge removal via landfilling isn't exceptionally functional because of land constraints and the ecological concerns included. Accordingly, severe natural control guidelines and the expanded sludge ...
