When left in the field, these residues increase water-holding capacity, control erosion, and add nutrients. They can be tilled back into the same soil. Ex- stem, leaves, stalks, etc. Post-harvest residues. Post-harvest residues are the materials left after processing. These residues are used as animal feed and soil amendments.
Target corn residue harvest in fields that you'll be planting corn in next year. Rotate residue harvest among fields so you don't remove residue from the same field every year. Reduce tillage following residue harvest. To add carbon back to the soil, use manure instead of or in addition to commercial fertilizer. Consider winter cover crops.
Water treatment residues (WTR) refer to the sludge that is formed during the production of potable. Water treatment residues comprise typically 3-10% of the conventional drinking water plant throughput, with approximately 90-95% of the waste stream produced at the clarification stage of the water treatment process.
Gas treating and processing. Natural gas is a mixture of many compounds, with methane (CH 4) being the main hydrocarbon constituent. When natural gas is produced from an underground reservoir, it is saturated with water vapor and might contain heavy hydrocarbon compounds as well as nonhydrocarbon impurities. In the raw state, …

In the study of dissipation of quinalphos and the effect of processing in cauliflower Lalitha et al. concluded that residues were considerably reduced from curds roasted in oil after boiling (36.3–68.6%) followed by simple boiling (10.1–60.0%) compared to the curds soaked in 2% salt water (14.7–43.2%) and soaked in tap water (13.0–40.5%).
Results reveal a mechanism for microscale N 2 O emissions: water absorption by plant residue that creates unique micro-environmental conditions, markedly different from those of the bulk soil ...
Water Pretreatment Benefits. Here are some of the key benefits provided by water pretreatment: Extends the life of subsequent reverse osmosis (RO) plant membranes. Ensures that the water delivered to the RO or EDI (electrodeionisation) system meets the required quality standard. Supports the delivery of a continuous and dependable water …
In phytovolatilization process, plants uptake and transpire water-soluble contaminants. Contaminants present in soluble form in crops undergo several reactions and eventually volatilize along the stream of transpiration into the atmosphere. ...

The production and processing of heavy oils will be influenced by the effectiveness of available technologies. Heavy crude oils are defined as any liquid petroleum with an API gravity in the range of 10–22.3° [ 2 ]. The fundamental characteristics of heavy crude oils are high viscosity and density, chemical complexity, high acidity, high ...
In the US, the main method is by adding chloramines or chlorine-based compounds. When these chemicals are added, they kill microorganisms, but they also …
Similarly it is unclear whether extensive processing of wild starchy plants such as acorns or chestnuts would be detectable in pottery residues, although diagnostic compounds have been identified ...
Plant residue decomposition is a microbially controlled "broad process" that involves a wide range of microorganisms [ 21, 22 ]. According to the dual microbial metabolism theory, the fate of ...
These water treatment residuals (WTR), sometimes called hydrosolids, "alum sludge," or "ferric sludge," are managed in a variety of ways, including via dischage to a wastewater treatment facility, landfill disposal, or land application. They are mostly water and aluminum or iron; they also contain a variety of trace amounts of metals, suspended ...
Three federal regulations provide the bulk of requirements applicable to residuals management and disposal include: RCRA, which governs the management of "solid" and hazardous wastes (note that a RCRA "solid" waste may be liquid or gaseous) and covers land disposal and land application (42 U.S.C. §§ 321 et seq.).
Water used by mining enterprises needs to be comprehensively recovered and utilized to achieve clean production. This requires the effective treatment of mineral processing wastewater. …
Regardless of the raw water source and quality and the processes used, WTPs can produce four types of residuals: Liquids, including brines, concentrates, backwash water, …
Because of their high-water content (~80%), the residues are prone to microbial spoilage and need to be dried immediately after processing, which is an economically limiting factor. While dry citrus peels are rich in pectin, cellulose, and hemicellulose, the disposal of the fresh peels is becoming a major problem for many …
Large volumes of sludge or residues are generated during the processing of raw water to make it fit for drinking purpose. A typical water treatment plant produces about 100,000 ton/year of sludge (Bourgeois et al., 2004). India is also producing huge amount of inevitable waste everyday at their WTPs which requires proper handling and …
According to the International Desalination Association, in June 2015, 18,426 desalination plants operated worldwide, producing 86.8 million cubic meters per day, providing water for 300 million people. This number increased from 78.4 million cubic meters in 2013, a 10.71% increase in 2 years.
The Bayer Process. The Bayer Process, which is used by about 80 active plants worldwide, is the primary method of producing aluminum from bauxite. Bauxite ore is dissolved in sodium hydroxide, or lye, at a high temperature and pressure. Then, the alumina and bauxite ores are separated by washing out the waste (red muds or sands) …
