Learn about Sludge Dewatering Geotube.
Dec 08, 2018


The geotube is a tubular geotextile with a filter structure woven from high-tough polypropylene yarn. The geotube dehydration curing method is to put the high-molecular flocculant into the sludge slurry in a certain proportion of the solution during the dredging process in the underwater dredging, fully mixed and filled into the Shigong pipe bag, and the equivalent hole diameter of the geotube is used. The filter structure and the liquid pressure in the bag have two dynamic factors, so that the water seeps out of the tube bag, and the sludge remains in the tube bag, thereby achieving the effect of reducing the volume of the sludge.


The geotube bag dehydration curing method has the following advantages:

①The diameter of the geotube bag can be changed according to the needs, and the length can reach up to 200m;

② geotube bag strength, filtration performance and long-term UV resistance;

③sergeant bags can be stacked in multiple layers to maximize the use of land;

④good volume reduction effect: 99% of the mud solids in the bag will remain, the volume is reduced by more than 80%, and the bag can be repeatedly filled;

⑤ curing effect is good: after 30 days of bagging, the moisture content of the sludge is reduced to 60%, and the moisture content of the sludge after 60 days is only 46%;

⑥The water filtered from the  geotube bag is reduced by 92%-96% compared with the harmful element index in the sludge mixture, and the filtered water completely meets the corresponding discharge standard;

⑦Construction is convenient and fast, and the construction period is short; for fully enclosed construction, it is not easy to cause secondary pollution.


 Geotube bag dehydration curing method application range:

①Municipal sludge treatment (water plant and sewage plant sludge), industrial sludge treatment (chemical, pharmaceutical, printing and dyeing sludge treatment);

②Ecological restoration: dewatering and subsequent disposal of sediments from rivers, lakes, reservoirs, seaports, docks, etc.

③Agriculture, animal husbandry and fishery farms wash manure sewage treatment, plantation wastewater treatment, aquaculture bed waste treatment, etc.;

④power plant fly ash and low ash treatment, steel plant desulfurization and dedusting sludge, aluminum plant, ceramics plant sludge treatment;

⑤Wastewater treatment and waste recycling of mining and washing, mining and dewatering of slurry in engineering construction.
