An aerobic treatment system ( ATS ), often called an aerobic septic system, is a small scale sewage treatment system similar to a septic tank system, but which uses an aerobic process for digestion rather than just the anaerobic process used in septic systems. These systems are commonly found in rural areas where public sewers are not available ...
Aerobic digestion. Aerobic digestion is a process in sewage treatment designed to reduce the volume of sewage sludge and make it suitable [ 1] for subsequent use. [ 2] More recently, technology has been developed that allows the treatment and reduction of other [ 3] organic waste, such as food, cardboard and horticultural waste.
Trickling filter. A trickling filter is a type of wastewater treatment system. It consists of a fixed bed of rocks, coke, gravel, slag, polyurethane foam, sphagnum peat moss, ceramic, or plastic media over which sewage or other wastewater flows downward and causes a layer of microbial slime ( biofilm) to grow, covering the bed of media.
The aerobic granules form excellent settling properties allowing for higher biomass concentrations (8g/L), the non-use of secondary clarifiers and the exclusion of major sludge recycle pumping in the Nereda system – the result is a compact (reduced plant footprints), simple system that requires significantly less chemicals and energy when ...
There are many other aerobic biological processes for treatment of wastewaters, for example activated sludge, trickling filters, rotating biological contactors and biofilters. They all have in common the use of oxygen (or air ) and microbial action to reduce the pollutants in wastewaters.
Vermifilter. A vermifilter (also vermi-digester or lumbrifilter) is an aerobic treatment system, consisting of a biological reactor containing media that filters organic material from wastewater. The media also provides a habitat for aerobic bacteria and composting earthworms that purify the wastewater by removing pathogens and oxygen demand ...
Powdered Activated Carbon Treatment (PACT) is a wastewater technology in which powdered activated carbon [1] [2] is added to an anaerobic or aerobic treatment system. [3] The carbon in the biological treatment process adsorbs recalcitrant compounds that are not readily biodegradable, thereby reducing the chemical oxygen demand of the wastewater and removing toxins.
