Continuous Pyrolysis Facility for Sewage Sludge Treatment
The amount of sewage sludge is catastrophically increased in the latest few decades due to functioning of the municipal sewage treatment facilities. Dry sewage sludge contains 70-90% of the organic substances and 10-30% of the inorganic substances, which are dangerous for human health in case of inappropriate utilization. The continuous pyrolysis technology presents the unique sewage sludge ...

JSTOR: A History of Human Waste As Fertilizers
In eighteenth-century Japan, human waste served a critical role in local agricultural production says JSTOR Daily. Their question in the recent article on sanitation history: can similar solutions help manage waste today? In the 1700s, Japanese community members saw human waste as a valuable substance for their crops and a viable tool for soil restoration and food security. It was so esteemed ...

Investigating psychological factors of behavioural intention of urban residents in South Australia to use treated stormwater for non-potable purposes
This paper reports on the intentions of urban residents in two South Australian Local Government Areas (LGAs) (council areas) to use stormwater treated through a managed aquifer recharge process for various potential non-potable uses. Data were collected through an online survey of the residents in these LGAs. The key finding is that, in common with recycled sewage water, the intention to use ...

Recycling of Urban Sewage through cladoceran culture system
The feasibility of using Urban Sewage (US) was tested in static water holdings for the culture of Daphnia, a cladoceran that is used as a live fish food. US was diluted to 60% (D40), 50% (D50), 40% (D60) and 30% (D70) by adding normal freshwater to constitute a total volume of 15 litres. Each culture medium (in triplicate) was inoculated with four units of Daphnia sps. per litre. The population ...

Use of sewage sludge ash (SSA) in the production of cement and concrete - a review
The use of recycled sewage sludge ash (SSA) in Portland cement and concrete has attracted a lot of global interest due the increase in sludge production and the limitation of land availability where it is used as a soil conditioner. These are in addition to rising environmental concerns. The major components of SSA are SiO2, CaO, Al2O3, Fe2O3, MgO and P2O5. These compounds, in theory, make SSA a ...

Earthships: sustainable housing alternative
This paper critiques an obscure form of sustainable architecture that addresses many of the environmental, social and economic challenges facing humanity. It focuses on the work of architect, Michael Reynolds, who has been experimenting with radical house designs and construction techniques over the past three and half decades. He addresses pollution, climate change and resource depletion by the ...

Sewage Sludge Recycling to Land and Disposal
The Problem: Sewage treatment is the process of removing contaminants from wastewater, primarily from household sewage. It includes physical, chemical, and biological processes to remove these contaminants and produce environmentally safe treated wastewater (or treated effluent). A by-product of sewage treatment is usually a semi-solid waste or slurry, called sewage sludge, that has to undergo ...

Acid dye removal from industrial wastewater by adsorption on treated sewage sludge
This study investigated the suitability of sewage sludge for the removal of Acid Blue 93 industrial wastewater. Washed sewage sludge (WS) and sludge activated carbon (AS) were used as adsorbents. The effect of pH, contact time, adsorbent dose and adsorption temperature was studied. Equilibrium isotherms for the adsorption were analysed by Freundlich and Langmuir isotherm models. The ...

Fate of phosphorus during anaerobic digestion of sludge from an EBPR plant
As part of their ongoing commitment to produce safe sewage sludge for recycling to agricultural land, Anglian Water are expanding their enhanced sludge treatment operations at four key sites across the Eastern region. The project at Whitlingham STW uses thermal hydrolysis as a pre-treatment to anaerobic digestion as the main sludge treatment process. As well as producing an enhanced treated ...

Food industry needs to step up on responsible groundwater use
Californians are all too familiar with what happens when water is not treated as the precious resource it is. But most of us are unaware of the enormous power we have through our day-to-day purchases, social media campaigns and petition drives to push food companies to take more responsibility in protecting global water supplies. Food production, the world’s biggest water user, is a major ...

A short guide to industrial wastewater treatment
While the sources of wastewater are kept on creating issues for human society, the shortage of drinking water also lagged on behind it. The scarcity of drinkable water is the most severe issue that is the society is confronting today. Though we love in a society whose 1/3rd% lands are acquired by water, yet the sources of drinkable water are limited. But thanks to the modern technology that has ...

Heavy metal accumulation in different parts of trees grown on sewage sludge
Sewage sludge is a rest product deriving from the wastewater treatment plants. It is rich in nutrients and essential elements. Therefore sludge on-land utilisation can create an added value by recovering energy from biomass produced on marginal lands. However, widespread on-land recycling of sewage sludge might be limited due to high heavy metal content. Health organisations show an increasing ...

Arizona Removing Obstacles to Wastewater Recycling
Starting in 2018, new rules will allow direct potable reuse of wastewater Existing technology can efficiently treat water to any desired level of purity, but no municipal water system in the United States has yet adopted direct potable reuse, or the use of recycled sewage for drinking water, mostly because popular psychological and political barriers have been difficult to overcome. Even in ...

Future-oriented further developments: wastewater heat utilization plants with a return on investment (ROI) of 2 - 6 years
Sewage is dirty and stinks. Out of sniffing distance – out of mind. Up until the 1980s sewage was taboo and not given the attention it deserves. One cold winter morning in 1988, 23 years ago, Urs Studer stopped beside a steaming manhole cover and wondered how such a source of heat could go untapped. Ever since he has been dedicating himself intensively to the recycling of sewage heat. At ...
