septic tank sludge

The main issue of concern was disposal of septic tank sludge.

Studies have shown that the composting of septic tank sludge is technically feasible.

The primary metals found in septic tank sludge are as follows:

Accumulation rate and characteristics of septic tank sludge and septage.

You must not use sewage sludge and septic tank sludge:

Septic tank sludge contains very high levels of contaminants, as can be seen from the following figures:

However, if there are no other options, the disposal of septic tank sludge at sanitary landfills is acceptable.

Septic tank sludge or septage is in fact a specific type of "fecal sludge" - a term nowadays widely used in the context of developing countries.

The farmer is also director of A1 Clear Drainage & Plumbing Solutions Ltd, a firm which is licensed to treat and screen septic tank sludge.

According to the available data, septic tank sludge contains no hazardous organic compounds, such as chlorinated substances (e.g., PCBs) or PAHs.

Septage or septic tank sludge refers to the partially treated sludge stored in a septic tank or (less commonly) in a pit latrine.

Septic tank sludge also contains various parasites, such as Ascaris and Trichuris, as well as many viruses, such as rotaviruses, the Norwalk virus, and enteric adenoviruses.

Caroline Simmers, SEPA’s investigating officer, said: “Mr Watson made no attempt to screen the considerable quantity of sewage-related litter from the septic tank sludge before spreading it on agricultural land.

It is very difficult to quantify the health risks associated with the management of septic sludge because no epidemiological follow-up is carried out on persons handling septic tank sludge on a daily basis.

Wastewater and Sludge Management (cont...) 8.3 Septic Tank Sludge (On-site Treatment) 8.3.1 Background On-site treatment is used when domestic sewage is not routed to a sewage system.

Special caution must therefore be exercised in the handling and management of septic tank sludge because, like municipal sewage sludge, it can cause various gastrointestinal infections. 8.3.3 Sludge Management The reclamation of septic tank sludge is desirable.

Septic tank and drain field microorganisms have very limited capability for catabolizing petroleum products and chlorinated solvents, and cannot remove dissolved metals; although some may sorb onto septic tank sludge or drain field soils, and concentrations may be diluted by other groundwater in the vicinity of the drain field.
