Cost-effective solution for dewatering

In general, sludge is pumped into Chengmei dewatering tubes with or without flocculants depending on the sludge particle sizes. During and after the filling process, the water dissipates through the fabric while the solid particles are retained within the geotextile tubes with low moisture contents. Afterwards, the volume of sludge reduces significantly, and a great deal of removal and disposal works are saved. Moreover, the installation and usage of Chengmei are very cost and time effective.

High sludge treatment capacity

Chengmei, which are made of polypropylene (PP) woven geotextiles with high tensile and seam strength, can contain a large volume of sludge. What’s more, the geotextiles have outstanding permeability and optimal aperture sizes to ensure high solid retention rate and dewatering efficiency simultaneously. In view of the types of treated sludge and flocculants added in, Chengmei dewatering tube series offer various woven structures of composing fabrics to achieve specific filtration properties.

Excellent durability with high quality

Chengmei dewatering tubes have excellent durability including high resistances to abrasion, ultraviolet light, oxidation, acid, alkali and bio-decomposition proven by numerous indoor and outdoor tests performed by accredited laboratories. The quality of Chengmei is ensured by the quality control and assurance process certified with ISO 9001.

Based on more than 15 years’ experience on geotextile manufacturing and fabrication, Chengmei dewatering tubes are available in customized design with high quality and cost effectiveness. Furthermore, Chengmei Geosynthetics provides technical support, including dewatering system design, facility and product selection, installation and treatment processing to offer optimized solutions to diverse dewatering needs.The benefits of using Chengmei are summarized as below:

• Excellent filtration characteristics to enhance processing efficiency

• Highly customized solutions provided for best cost-effectiveness

• Easy installationand few additional facilities needed to save time and costs

• Environmentally friendly with less carbon emission
