APPLICATION (Shore Protection) Erosion and sedimentation are the two fundamental problems that coastal and river management is fighting with. However, natural disasters and the raise of man-made ® structures sometimes make the problems worst. The application of ACETube is an easier way to prevent shoreline erosion, protect coastal infrastructure, and enable dredging of river channels to reduce the possibility of flooding.

ACETube® can be applied in the following constructions and engineering purposes: Shoreline Remediation

River / Wetland Remediation

Dune Reinforcement

River Bank Protection

Groin

Wetland Remediation

Detached Breakwater

River channel Dredging

Submerged Breakwater

Coastal Infrastructure Protection Reclamation Works Cofferdam Construction Pipeline Protection

APPLICATION (Environmental Remediation) Dredging and dewatering work are one of the main tasks in environmental remediation. ® However, these tasks can be challenging in both budget and operation. ACETube is to provide an effective way of dewatering treatment to waste/sludge/deposit from industrial, municipal, mining, agricultural, waterway areas and etc. It could reduce the cost and time in dewatering process, and improve the effectiveness of the dewatering treatment (compare with the drying bed method).

ACETube® can provide dewatering treatment in the following areas: Industrial Sludge

Agricultural Waste

To dewater industrial waste and sludge from

To collect and treat the soil and waste from livestock and

factories (such as paper mill, sawmill, chemical

farming.

related and etc.) for disposal.

Mining Waste To filter ash, tailings, and other solid materials from the mining

Sewage Sludge To substitute for random discharge and exposed ®

waste lagoons, ACETube provides one low impact treatment for the environment.

water.

Sediments in Water To dredge sediments in river, reservoir, lagoon, lake, and pond and keep these systems in proper function.

Real Case ®

ACETube is applied in fish port building project as the breakwater structure. The breakwater constructed is about 671 meters. In-situ sand ® is filled into ACETube to form the perimeter barrier structure of the breakwater. Sand is filled and compacted layer-by-layer inside the enclosure of the perimeter barrier structure as the core of the breakwater. Cost-effectiveness and short construction period are achieved with this ® innovative application of ACETube .

WHY ACETube® Key Features:

Key Benefits:

• High grade fabric with satisfactory strength

• Cost-efficient

• Excellent resistance to UV, alkaline, and acid

• High efficiency of construction

• Outstanding permeability

• Environmentally-friendly with less carbon emission and odor

• Customized design available

Real Case ®

ACETube system is used in municipal sludge treatment for dewatering and disposal purposes. Sludge with polymeric additive is pumped into ® ® ACETube firstly; the size of ACETube is 21 meters in circumference and 30 meters in length. The dewatering and sedimentation process automatically start with gravity. Sludge is consolidated to solid in ® ACETube and is ready for disposal. More than 600,000 cubic meters of sludge are dewatered in this case. This process is relatively cost-effective for a dewatering treatment.
