Dewatering Tubes,  also referred to as GeoTubes or Geotextile dewatering bags  are used widely in most dewatering applications. The Dewatering tube or Geotube technology is used in industries including municipal, pulp and paper and mining.  When used correctly and optimized, dewatering tubes save time, money and the environment.  Your savings are in the bag.

Uses:

Dewatering Tubes are used for both raw water and wastewater.  A BOD reduction of up to 90% coupled with high cake solids from water reduction.  Agriculture operations with livestock, dairies and piggeries have also embraced the technology which is simple, efficient and economical.

Sludge dewatering of primary and secondary waste water ponds is also ideal through dewatering tubes.

Advantages:

High flow rates along with the potential for leaving the dewatered sludge in the dewatering bag (container)  make this technology unequaled.  The dewatering tubes can sit for years before removing sludge allowing for a extended disposal budget.

We have developed specialty polymers that enhance the throughput, water clarity (TSS) and sludge compaction.  Our polymers are fast activating and formulated for the sludge  and not “off the shelf” products.

Spinpro Dewatering Tubes:

Spinpro is a factory direct source for geotextile dewatering tubes.  Our high capacity geotextile dewatering tubes are available in both polypropylene and polyester.  We stock standard and custom sizes up to 120’′ circumference X 300′ long.

We also produce hanging bags for testing, cubic yard bags and roll off dewatering bags for smaller projects.  Our support products also include liners, geo-grid, geo-membranes, silt fence, erosion control, turbidity curtains and silt screens.

Dewatering Tube Process

Dewatering Tubes:

Dewatering Tubes are filled with sediments containing sand, silt, clay or organics and or a combination all of these sediments.  These type of tubes are also used extensively in Industrial and Municipal applications.  In these applications the sludge is the end product or waste from various processes.

Some sediments like sands, silts with low organic content can be dewatered without flocculent.  This type of filling is typical of dewatering tubes used for dykes or protecting shore lines.  The solid particles are trapped inside the geotextile material and the water is forced through the fabric.

Treatment:

Other sludge’s especially those with a high organic composition or manufactured sludge’s must be pre-treated.  The treatment consists of using conditioners such as polymers or coagulents.  This conditioning  coagulates the particles together so they are too large to pass through the woven material.

How Dewatering Tubes Work

Dewatering Tubes:

The dewatering tube material is designed as a filter but most the finer filtration is done by the material (dewatered sludge) in the tube.  As the water is squeezed from the sludge it passes through the accumulated sludge to exit the tube.

The result is optimum clarification serving the purpose of both a dewatering device and a fine filter.  The dewatering tube is filled several times to maximize the compression on the dewatered sludge thereby drying the material.  Once the sludge has dried to the desired consistency the solid materials can be easily removed.

Disposal:

The residual sludge is excavated, transported and disposed of in an environmentally friendly way saving time and expense. The tube material has a degradation time of 7 -15 years depending on the application and u.v. protection in the material.  In beach erosion applications for lakes, marinas and waterways the tubes are left in place to stop shoreline erosion, build berms and dykes etc

Why SPINPRO Tubes

Dewatering Tubes:

Spinpro dewatering tubes are designed for higher capacity and efficiency.  This allows for higher pumping rates, faster dewatering, and enhanced filtration with fewer bags.  Increased elasticity in the material combined with the strongest seams available help to manipulate the filling process.

The result is more sludge in the bag.  As each project is unique we work closely with our customers.

Process:

We alter the bag design where necessary and speed up production to supply tubes for emergencies and large orders.  With our guidance you will be able to meet or exceed water discharge specifications and dewatered sludge moisture content.

This results in lower transportation and disposal costs of the dewatered sludge as well as reduced water purification costs. When used properly our dewatering tubes are designed to save time, money and our environment.
