Biogas Plant Grit Removal System Extracts
The capability to extract grit and silt also extends to root crops, food waste, slurry from cattle bedded on ash, sand and other high grit inputs. In short, there is never a need to stop the digester to empty it. No downtime. No loss of the heat or power for use on the farm and export to the grid. And, importantly, no health and safety risks associated with the opening of the tank.

Water impacts of oil sands Energy Education
One major environmental impact that comes from extraction in the oil sands is the water water used in oil sands development is used in surface mining to separate the extracted oil sand into sand and bitumen components. Then, water is converted to steam in SAGD operations to separate the bitumen from the sand before it is extracted. The water used in the oil sands

Water Management in oil sands | Natural
If the oil sand is deep, underground methods are used to extract the bitumen while leaving the sand in place (in situ extraction). The most common in situ technique is steamassisted gravity drainage (SAGD). In SAGD, steam is pumped into a horizontal well to heat the bitumen which then flows to a second well that was drilled below the first well, from which the bitumen is pumped to the surface
