The nutrient-rich organic materials resulting from the treatment of sewage sludge and wastewater.
The solids in waste water that can be removed by filters.
Wastewater solids that have been treated for safe use as a fertilizer or soil amendment.
Nutrient-rich organic material produced from the stabilization of sewage sludge and residential septage that meet specific criteria and are suitable for land application.
Organic waste by-products from ag production and municipal sewage treatment plants that are spread on farm fields as a natural fertilizer or soil amendment.
Processed sludges from industrial activities (excluding agricultural effluents) that may be suitable for reuse as soil conditioners or fertiliser substitutes.
Means sewage sludge, including exceptional quality biosolids, placed on or applied to land as a soil amendment, conditioner, or fertilizer.
Organic fertilizer or soil amendments produced by the treatment of domestic wastewater. Biosolids consist primarily of dead microbes and other organic matter. Untreated sludge or sludge that does not conform to regulated pollutants and pathogen treatment requirements are not considered biosolids.
solid by-products of waste water treatment processes.
Biosolids are complex mixtures that can contain pollutants from household, commercial and industrial wastewaters with organic contaminants (such as pharmaceuticals), inorganic contaminants (metals and trace elements) and pathogens (bacteria, viruses and parasites). Depending upon the extent of treatment, biosolids are often applied such areas as farms, parks, golf courses, lawns and home gardens.
A term used to describe the primarily organic solid product, produced by wastewater treatment processes, that can be beneficially recycled. Beneficial recycling includes land application to improve soil characteristics, heat and energy recovery, and production of useful products. Biosolids must meet certain government specified criteria depending on its use (e.g., fertilizer or soil amendment).
Stabilised organic solids derived from sewage treatment processes that can be managed and used safely for nutrient, soil conditioning, energy or other value.
sludge that is intended for beneficial use. Biosolids must meet certain government-specified standards depending on use as a fertilizer or as a soil additive.
The solid portion of wastewater that is separated from the liquid in the treatment plant's clarifiers. After meeting State and Federal regulations it may be used as a soil amendment.
the organic product that results from sewage treatment processes (alternatively known as sewage slugde) and food processing waste.
Waste that is predominantly organic that has been treated by aerobic or anaerobic digestion or other means of stabilization. Biosolids include residue from sewage works.
Solid organic matter recovered from municipal wastewater treatment that can be beneficially used, especially as a fertilizer. “Biosolids” are solids that have been stabilized within the treatment process, whereas “sludge” has not.
Nutrient-rich, organic material generated from household waste, removed during the treatment process. Once digested and dewatered, the material, called Biosolids, can be beneficially recycled.
A nutrient-rich organic material resulting from the treatment of wastewater. Unprocessed wastewater treatment sludge must at least be digested before being referred to as biosolids. Biosolids contain nitrogen and phosphorus along with other supplementary nutrients in smaller doses, such as potassium, sulfur, magnesium, calcium, copper and zinc.
wastewater sludge that has been treated to be safe for land application. Here, safety refers to the reduction or elimination of disease-causing organisms.
a nutrient-rich organic material resulting from the treatment of wastewater. Biosolids contain nitrogen and phosphorus along with other supplementary nutrients in smaller doses, such as potassium, sulfur, magnesium, calcium, copper and zinc. Soil that is lacking in these substances can be reclaimed with biosolids use. The application of biosolids to land improves soil properties and plant productivity, and reduces dependence on inorganic fertilizers.
Solids from wastewater treatment that have been processed into products suitable for beneficial use for purposes such as agriculture or forestry.
Sewage sludge that is stabilised and suitable for beneficial reuse
The treated and stabilised solids in sewage.
Treated and dried sewage sludge
are organic solids derived from biological wastewater treatment processes that are in a state where they can be used as nutrients and soil conditioning agents, a source of energy or some other use.
The organic product that results from sewage treatment processes (ie material referred to alternatively as sewage sludge). Solids become biosolids when they come out of a digester or other treatment process and can be beneficially used. Until such solids are suitable for beneficial use, they are defined as wastewater solids. The solids content in biosolids should be equal to or greater than 0.5% (w/v).
The organic by-product of wastewater treatment (also called "sludge").Biosolids contain essential plant nutrient and organic matter and are recycled as a fertilizer and soil amendment.
Digested solids removed from wastewater.
A primarily organic solid product, produced by wastewater treatment processes, that can be beneficially recycled. The word biosolids is replacing the word sludge. Back to the Top
Primarily organic solid product produced by the wastewater treatment process that can be benefically recycled.
The solids, or sludge, that remain after wastewater treatment. This material is separated from the cleaned water, treated and composted into fertilizer. Biosolids are often referred to as sludge.
Biosolids are nutrient-rich solid materials that are produced from the organic residuals that are a byproduct of the treatment of domestic wastewater in a wastewater treatment plant. To create biosolids, these residuals are further treated to reduce pathogens and vector attraction by any of a number of approved methods.
