Treatment of shrimp hatchery effluents
Sedimentation can be an excellent solution as long as the hatchery has enough area to build and operate sedimentation ponds with adequate dimensions for the separation of suspended solids typical of shrimp hatcheries. Biofiltration. Biofiltration is an example of a technology which, although very simple, is very efficient in the remediation of ...
Could beavers help deal with climate change?
"That's the big question concerning bogs and mires, which have accumulated carbon for a long time." The results indicated that globally, carbon sedimentation in beaver ponds totaled to 3.8 teragrams per year, with 100 times as much carbon already stored for millennia in these rodents' habitats. Overall, beavers annually sequester an ...

Types of peatlands
Countries classify their peatlands differently, but most agree on two main classes: bogs and fens (with some swamps being a third). Most commonly known special peatland types are e.g. aapa mires, blanket bogs, palsa mires, spring fens, and tropical peat swamp forest. Many languages have special peatland expressions with even regional differences.

Sedimentation/ Thickening Ponds | SSWM
Allowing the sludge to degrade anaerobically in sedimentation / thickening ponds can do this. The same type of pond can be used to thicken sludge which is already partially stabilised (e.g., originating from Septic Tanks, etc.), although it undergoes less degradation and requires more time to settle. The degradation process may actually hinder ...

A temporal increase in the natural SSC of the Tajuelo stream does not imply that the sedimentation pond system fails, since the average pond retention efficiency is high, 98.2% (Table 4). It means that obtaining those high retention figures involves changing the hydrologic and sedimentary dynamics of the hillslope where the mine is settled, and ...

Sedimentation in Pond or Lake
Question: How can sedimentation affect a pond or lake? Answer: "Excess sedimentation is a storage point and a creator of phosphorous. Phosphorous is a main element for undesirable algae growth. Sediment can also limit capacity of retention ponds, which defeat the purpose of their design." Right-Click Here to Save Audio. Back to the Video Library
An Introduction to Floating Wetlands for Stormwater Ponds
Floating Wetlands in Stormwater Ponds.
