Murphy Family Vestal Hog Farms Dragonfly Wastewater Treatment System - Case Study
The proliferation of large and efficient confined animal farms has created a significant problem for the processing and disposal of the water used for cleaning and cooling as well as other applications on the typical farm. The answer is Water Energy’s utilization of the technology presently known as the Dragonfly Water Treatment System. The result is the only hog farm capable of reusing ...

How to treat wastewater in livestock farm?
Livestock wastewater is the third largest source of pollution after industrial wastewater and domestic wastewater. It has the characteristics of high organic matter concentration, high ammonia nitrogen concentration, high suspended solids and pathogenic bacteria content, etc. It is a kind of high-concentration organic wastewater that is difficult to treat. Why does livestock wastewater need to ...

Why are some French farmers sludge-takers? Some agronomic and socioeconomic explanations
The continued spreading of household wastewater sludge on farmlands is a major economic and environmental issue. This practice is being challenged in France, mainly through pressure from the agrifood business. Here, by means of an agronomic analysis performed on 60 farms, we show the relevance of the following variables: proportion of arable land, technical performance of the farm, and quality ...

The transport of three emerging pollutants through an agricultural soil irrigated with untreated wastewater
The aim of this work was to determine the mobility of naproxen, carbamazepine, and triclosan through a wastewater-irrigated agricultural soil. Transport experiments were carried out using undisturbed soil columns taken at 10 and 40 cm depths. The mobilization of the pollutants was evaluated using two hydrological regimes transient flow for superficial columns and steady-state conditions for the ...

Effectiveness of recovered Magnesium Phosphates as fertilizers in neutral and slightly Alkaline soils
Magnesium phosphates such as struvite (MgNH4PO4 · 6H2O) can be recovered from municipal, industrial, and agricultural wastewaters. However, limited information is available on the beneficial reuse of these recovered products; research has focused on low pH soils. This study determined whether recovered struvite and dittmarite (MgNH4PO4 · H2O) were effective P fertilizers in neutral to slightly ...

Experience in improving fertiliser value of compost by enriching with urine
Urine contains a lot of nitrogen, phosphorus and potassium, and could act as valuable plant fertiliser. But urine is often either flushed down a toilet or enters a pit latrine, thus being lost to agriculture and increasing surface and groundwater contamination with nitrogen. Ecological sanitation concepts are closing the loop of nutrients contained in wastewater with agriculture. Besides ...

Pesticide and Pathogen Contamination of Vegetables in Ghana’s Urban Markets
Abstract The objective of the study was to determine and compare the current level of exposure of the Ghanaian urban population to hazardous pesticide and fecal coliform contamination through the consumption of fresh vegetables produced in intensive urban and periurban smallholder agriculture with informal wastewater irrigation. A total of 180 vegetable samples (lettuce, cabbage, and spring ...

Reuse of California brine olive oil processing wastewater to meet zero discharge goal
Abstract Reuse of low strength municipal wastewater is becoming quite common and many technologies are available for that purpose. However, treatment and reuse/recycling of high strength industrial wastewater is still a challenge. In this paper we present some case studies with implemented integrated systems to achieve zero discharge goal. We will concentrate on the description of a wastewater ...

New methodical way for sustainable farming systems using treated sewage water in irrigation in Jordan
Most scientific approaches in research are done under objectified, controlled conditions. Such experiments do not reflect the everyday reality of farmers. Moreover, experimental research in agriculture does not always reflect the interests of Jordanian farmers. Another type of research is therefore needed. We need research that integrates Gamma and Beta sciences, farmers and scientists and the ...

Prevalence and types of Campylobacter on poultry farms and in their direct environment
To study whether broiler and layer farms contribute to the environmental Campylobacter load, environmental matrices at or close to farms, and caecal material from chickens, were examined. Similarity between Campylobacter from poultry and environment was tested based on species identification and Multilocus Sequence Typing. Campylobacter prevalence in caecal samples was 97% at layer farms (n = ...
