Geotube® technology was the solution implemented in an urban Wastewater Treatment Plant to respond to the significant increase in the sludge volume that inflew in the wastewater treatment process during the hottest months in Portugal. Geosin supplies and supervises the implementation of the global solution, from materials dedicated to soil sealing to the sludge dewatering technique. This technique allows the sludge confinemnet and storage at the same time.
The material TenCate Polyfelt TS was applied as a separator in the rehabilitation of urban roads in the north of the country. The wide variety of widths on roll availabillty minimizes material waste in this type of works.
As an immediate solution to the problem of heavy vehicles access to a WWTP (Waste Water Treatment Plant), needed for the transport of dewatered sludge, TenCate Geotube® sludge dewatering technology was the solution! Beside dewatering function, confinement and temporary storage simultaneously can be also assured by Geotube® system. It allows continuity of the current dewatering operation until the moment that ideal access conditions of these vehicles to the WWTP have been restored.
Geosin followed the application of TenCate Polyfelt P in a railway maintenance work, carried out at night in the center of the country. The replacement of the ballast and the placement of a non-woven geotextile separator made of high performance polypropylene are fundamental to guarantee the service level of the line.
Geotube® MDS® solution is designed for smaller applications and/or small areas. A Geotube® MDS® unit of 9.8m3 capacity, dimensioned for standard containers, allowed the dewatering of 200 m3 of sludge produced in the wastewater treatment process of a textile dyeing industry. Geotube® solution assures an high reduction of the sludge volume (95%) to be managed and allows the WWTP to carry out this operation only once an year.
The TenCate polypropylene geotextile was applied as protection to the fuel tanks of a new commercial area in the north of Portugal. Also in this type of applications, our material, certified in environmental and chemical terms, is a guarantee of durability.
The TenCate Geotube® technology was used for treatment and dewatering of the sludge accumulated in a lagoon dedicated to urban effluent treatment. The first lagoon had high levels of solids so a fast and effective action was required! Geotube® technology allows high levels of dry matter, providing a significant reduction of the sludge volume to be managed, a considerable reduction in economic costs as well as a reduced footprint, thus contributing positively to this kind operation: cleaning and removal sludge from ponds in public WWTP.
Our non-woven polypropylene geotextile TenCate Polyfelt TS was applied to a mining environmental remediation project in the south of Portugal. The advantages of polypropylene over polyester in mechanical, hydraulic and chemical terms make this material the most suitable for this type of applications.
TenCate Geotube® technology was the solution adopted for collection and dewatering the retained sludge in a biogas reactor. The Geotube® MDS (Mobile Dewatering System) units applied adapt to the dimensions of standard metal containers, thereby facilitating the control of filtered water and the routing of sludge to its final destination.
TenCate Polyfelt TS was applied as a geotechnical solution to filter and separate distinct soil layers in the execution of a new commercial surface in the North of Portugal. The use of this geotextile ensures high long-term performance under rigorous mechanical and hydraulic demands.
