Dewatering and Thickening of Municipal Sewage Sludge using the Decanter. Flottweg has more than 50 years of experience in dewatering and thickening sewage slurry. We know the special requirements of sewage treatment plants and the water industry. As a result, we have developed a special decanter series especially for sewage treatment plants: the Flottweg C series.
The waste-sludge generated by primary and secondary (biological) treatment of municipal & industrial wastewater needs to be managed at every plant big or small. In the larger sewage treatment facilities waste sludge thickening and dewatering has always been assumed a necessity without the planners and designers thinking twice about the cost requirements.
In the smaller and decentralized STP’s where available investment is always lower, the on-site waste-sludge management (thickening & dewatering) maybe compromis...
AQQA is used in industrial wastewater treatment to: separate the sludge from the clear water in membrane bio reactors. constitute the final filtration of the effluent of standard sewage treatment plants (tertiary treatment). keep specialized bacteria in the system, that can biologically degrade organic matter. enable Zero Liquid Discharge: prefiltration for reverse osmosis systems.
For industrial and municipal treatment plants; Chemical scrubbers, biological towers and adsorption systems to remove hydrogen sulfide, mercaptans, other organic sulfur compounds and ammonia from digesters, pump stations, ponds, grit and screening works, sludge filter presses and dryers. Special Wet Electrostatic Precipitator for sewage sludge incinerators. Stripping ammonia and other volatile compounds. Decarbonization removal of carbon dioxide from wastewater.
VITONE ECO decanters, together with all auxiliary machinery such as polypreparers, removal dewatered sludge screws, pumps, etcetera, are meant for the following uses: dehydration and thickening of sewage from civil and industrial purification plants; dehydration of vegetable biomasses and zootechnical sludge; waste water treatment for distilleries and fellmongering waste.
LWT`s dredging systems are used for aeration lagoon / pond dredging applications. A dredging system for removal and disposal of raw sewage solids, decayed algae and microorganisms, and algae-laden sludge results in a long term solution for treatment plants. Aeration lagoon / pond dredging increases lagoon storage volume, provides improved detention time, and accommodates increased plant flow.
If toxicity is identified in a mixed sewage entering a treatment works, the problem for the plant manager is to track and identify the source of the toxicity. This can be done by sampling the effluent stream at various points in its length. By working in a logical sequence back up the sewer network the number of samples can be minimised. This type of testing should be rigorously enforced for new product introduction by a waste producer, as well as sampling the effluents directly at source. The samples would be...
