Addressing Human Waste Fertilizer Dangers Due To Pharmaceutical Residues

Advances in medicine have made maintaining health and curing diseases possible with the use of pharmaceuticals such as antibiotics. However, the increasing use of these drugs have brought about concerns on the negative impact of pharmaceutical residues on the environment. Pharmaceutical residues mainly enter the environment through excretion, either as the original pharmaceutical compound, or…

New Study May Provide Possible Solution to Estrogen in Biosolids Run-off

A new study conducted by Penn State’s College of Agricultural Sciences showed that shallow disk injection compared to the surface broadcast of manure into the soil considerably lowered estrogen in biosolids runoff. The former biosolids application method may be an effective strategy in controlling the mobilization of estrogen thereby significantly improving downstream water quality. The…

Upcycling Nitrogen to Convert Sewage Sludge to Animal Feed

Nitrogen exists in many forms in the environment and can enter aquatic systems from fertilizer run-off and wastewater discharges. Treated domestic sewage sludge will have varying levels of nitrogen, depending on the method of treatment used. Most treatment plants decrease the level of total nitrogen in sewage sludge via cell synthesis and solids removal. However,…

Fatbergs: A Waste Management Problem

Fatbergs: A Waste Management Problem

February 21, 2018 | Under News | Posted by | No Comments

One of the more difficult challenges facing waste management in water treatment is the removal of fat aggregations or fatbergs. Fatbergs are congealed lumps of fat that come from a variety of sources which then bind to other wastes that do not degrade in water such as sanitary napkins, wet wipes, condoms, and diapers to…
