Reed Beds

-

The reed bed technology or constructed wetland is an high functional efficiency eco-friendly wastewater treatment plant that has a lower cost and lower carbon footprint compare to conventional wastewater treatment methods. Reed Bed use waste to produce new resources in order to contribute to the natural environment cycle regeneration. The main principle consists of filtering and aerating waste water in different stage of sand filters basins planted with green wetland plants, in order to produce treated water.

Reed beds are natural habitats found in floodplains, waterlogged depressions, and estuaries. Reed beds are part of a succession from young reeds colonising open water or wet ground through a gradation of increasingly dry ground. As reed beds age, they build up a considerable litter layer that eventually rises above the water level and that ultimately provides opportunities for scrub or woodland invasion. Artificial reed beds are used to remove pollutants from grey water.


Reed beds vary in the species that they can support, depending upon water levels within the wetland system, climate, seasonal variations, and the nutrient status and salinity of the water. Reed swamps have 20 cm or more of surface water during the summer and often have high invertebrate and bird species use. Reed fens have water levels at or below the surface during the summer and are often more botanically complex. Reeds and similar plants do not generally grow in very acidic water; so, in these situations, reed beds are replaced by bogs and vegetation such as poor fen.

Although common reeds are characteristic of reed beds, not all vegetation dominated by this species is characteristic of reed beds. It also commonly occurs in unmanaged, damp grassland and as an understorey in certain types of damp woodland.

SLUDGE REDUCTION POTENTIAL OF METAZOA

 A way to reduce excess sludge production and enhance mineralization is to retain the sludge completely in a treatment plant, which can be achieved by a membrane separation process. There the sludge concentration is expected to stabilize at the level at which energy supplied is fully utilized for maintenance purpose. Another way to enhance mineralization and reduce the sludge production is to exploit the organism in the process that predate on bacteria (sludge), by promoting their growth in an extra “grazing stage”. During energy transfer from bacteria to higher trophic level organisms, energy is lost due to inefficient biomass conversion and thus the predator may make a large contribution to biomass replacement. A long sludge retention period in membrane bioreactors (MBR) is very suitable for the abundant growth of these higher organisms. This predatory population in the system can be exploited to enhance mineralization and reduce sludge production.  High metazoa density lead...

Pseudomonas in wastewater treatment

Pseudomonas in wastewater treatment-  Source- Céline Slekovec, Julie Plantin, and Didier Hocquet  Pseudomonas is a genus of Gram-negative, Gammaproteobacteria, belonging to the family Pseudomonadaceae and containing 191 validly described species. The members of the genus demonstrate a great deal of metabolic diversity and consequently are able to colonize a wide range of niches. Pseudomonas aeruginosa was isolated consistently from domestic and hospital sewage. In domestic sewage the numbers were usually less than 30,000 per 100 ml whereas counts above 500,000 per 100 ml were frequently obtained in hospital sewage. Correspondingly high counts of Escherichia coli were not found in hospital sewage and the ratio of E. coli to P. aeruginosa was usually less than 25 compared to ratios of over 500 often found in ordinary domestic sewage. During passage through sewage treatment plants the numbers of both bacteria were reduced by about 90% so that their ratio in the effluent remained...

ANAEROBIC FERMENTATION

  Most of the organics in the sewage sludge were transformed into useful energy by the anaerobic fermentation of microorganism. Plenty of nitrogen, phosphate, potassium could be separated from the leachate produced in this fermentation which makes the recycling of sewage sludge much easier. This method could also help stabilize and decrease the amount of sewage sludge and make it harmless.  Here is a brief account on the mechanism of this process. The sewage sludge samples are taken in conical flasks; the flasks were sealed and kept in an airtight and anaerobic condition. Then the conical flasks were kept in thermostatic water bath box, controlling the temperature at 95°C to improve the efficiency of the anaerobic fermentation of the sewage sludge. The conical flasks were taken out and put into a container with oxygen at the 2th, 7th, 10th, 14th, 17th, 21th, and 28th day after the beginning of the anaerobic fermentation, respectively. When the flasks were taken out, a little o...
