Dewatering Filter Tubes
Aquaculture Wastewater Processing Solutions
Dewatering filter tubes provide a simple, proven, and economical solution for the treatment of aquaculture wastewater. Geotextile tubes are an effective way to filter the wastewater that aquaculture produces, containing the untreated wastewater while separating the clear effluent. Dewatering filter tubes offer a range of useful benefits in the filtration of wastewater by saving space, time, cost, and increased effectiveness.
Benefits of Dewatering Aquaculture Wastewater
Geotextile dewatering filter tubes provide a host of benefits as an effective component of your aquaculture wastewater treatment system:
- Save Space. Our Geotextile Tubes for wastewater (aquaculture) are available in lengths up to 200 feet, with choices of diameter of between 15 to 90 feet. Available in standard sizes, we can also customize the size to easily fit just about any location's unique space requirements. For projects processing a smaller volume of filtrates, consider dewatering bags.
- Cost Efficient. Geotextile dewatering filter tubes are a practical and economical component of an aquaculture wastewater processing.
- Maximize Return. Turn wastewater byproduct into an additional profit stream, or repurpose it for greater efficiency on your farm. Dewatered aquaculture effluent (clear water, separated from the solids) can be captured for reuse with the use of containment berms and liquid storage tanks. It's also gaining popularity as a fertilizer for aquaponics and land based agriculture. Waste aolids are neatly contained within the dewatering filter tube for disposal, repurposing, or incineration.
- Meet Compliance Requirements. Avoid costly fines by using dewatering tubes to filter contaminants as an important part of an aquaculture wastewater processing system.
How Dewatering Filter Tubes Work in Treating Aquaculture Wastewater
The dewatering process can be used for either fresh or salt water aquaculture farming. It simplifies the recirculation process and greatly reduces nutrient loading. The majority of the solids are contained in the dewatering process when using dewatering filter Tubes.
While the process for using a dewatering filter tube is simple, it is important that the specific requirements and needs of your project are taken into consideration. Elements that can help us in determining the right fabrics, design and geotextile tube construction for your dewatering project:
- What type of wastewater (aquaculture) will be processed?
- Are there specific requirements/regulations as part of your local permitting process?
- What is the expected output rate for the wastewater from the aquaculture process?
- Do you have an expected flow rate for the effluent (clear water)?
- What do you plan to do with the effluent? How will you capture it? Do you need a holding tank?
- What do you plan to do with the waste solids?
- Are there any space or environmental concerns in the location where you plan to place the dewatering filter tube?
Using an Aquaculture Wastewater Processing System
Step 1: Identify the best location for your dewatering filter tube. Consider the lay of the land and select a relatively flat area, as tubes placed on inclines can be unstable and risk damage to personnel and equipment. If planning to relocate the tube once filled, plan for how you'll access the geotextile tube for loading and transportation.
Step 2: Install the geotextile dewatering filter tubes, following specifications and GEI Works Installation Instructions.
Note: Should you need on-site assistance, we have a mobile team that's available world-wide to assist in the installation of our dewatering filter tubes with your aquaculture wastewater processing system.
Step 3: If using polymers or flocculants, place the appropriate type for your wastewater mix in the geotextile tube before filling it. (Polymers/flocculants help the suspended solids coagulate and more quickly separate from the water. They are designed specifically to attract the type of material that is to be separated from the aquaculture wastewater.)
Step 4: The dewatering process will start immediately once the process water enters the tube, with clear water (effluent) seeping through the pours of the geotextile tube's fabric. The type of contaminants in the water will determine what (if any) additional processing is needed for discharge (or reuse) of the dewatered aquaculture effluent.
Note: If planning to reuse the aquaculture wastewater processing effluent, we recommend using a secondary containment berm by GEI Works to conveniently and cleanly capture the clear water.
Step 5: Monitor the tube periodically to prevent overfilling. Once the dewatering filter tube has reached capacity, it should be disconnected, with the piping reconnected with the next geotextile tube.
