Organic Industrial Sludge such as slaughterhouse waste, chicken rendering, food processing waste, restaurant and grease trap waste, agricultural waste is what is known as emulsified waste/sludge. This is treated differently than inorganic waste.
- Scientific Solution
Flo Trend’s Laboratory and Operations Specialists can assist with identifying key features such as Total Suspended Solids (TSS), Total Dissolved Solids (TDS), pH, volume, what other chemicals and flocculants may be in the sludge, as well as the sludge’s location in the waste stream. From there, a lab tested polymer will be matched.
- Equipment: Dewatering Container Filters
When it comes to Industrial Organics which are emulsified in the waste stream, Sludge Mate® Dewatering Container Filters are an excellent solution. In situations with a small footprint or where a pilot plant is in place smaller dewatering container filters that can be moved by forklift, such as Self Dumping Hoppers and Front, Rear, and Side Loading container filters fit nicely.
- Static Mixing and Dewatering Polymer
It is important to note that the Polymer and the Sludge must be thoroughly mixed as it is injected. This can be achieved using a Mix Mate® Static Mixer to thoroughly combine two or more streams. The Mix Mate® is also a component part of the Poly Mate® Polymer Injection Unit and the Insta-Mix® Polymer Injection Unit.
As the flocculated sludge enters the Sludge Mate® Dewatering Container Filter the suspended solids clump into cauliflower-like lumps, separating from the water. The water passes through the permanent filter media inside the container filter and exits through the drains at the bottom. The unique center panel inside allows for quicker dewatering and the permanent filter media is a year over year value when compared to repeatedly purchasing disposable filter media.
- Settling and Dewatering
After 32-48 hours the sludge will have settled and dewatered to a cake that meets or exceeds the paint filter test or coffee filter test used at landfills. Using this process, the box can dewater multiple batches before it is nearly full and needs to be dumped, land applied, or composted. The savings from dry hauling dried sludge vs liquid hauling for disposal is significant and will usually pay for the dewatering box within a year.
ORGANIC INDUSTRIAL OPTIONS & APPLICATIONS
- Grease Trap Waste
- Liquid Waste Haulers
- Food Processing
- Agricultural Wastewater
- Septic & Portable Toilet Wastewater-Municipal
Biosolid waste can be easily flocculated using a Poly Mate® Polymer Injection System to mix and inject polymer into sludges and slurries as they enter a Sludge Mate® Container Filter. The free and clear water will then run out of the drains at the bottom with a reduced biological oxygen demand and chemical oxygen demand (BOD and COD), ready to return to circulation at the headworks of the plant for treatment.
When the dewatering sludge is allowed to set in the dewatering equipment for 36-48 hours you are left with a solids cake that will easily meet or exceed the paint filter test required for dry hauling to the landfill or land applying.
Grease Trap Waste is typically lipid heavy and must be treated in a holding tank– in many cases a frac tank– using lime to raise the ph to a level where polymer will be able to bind to it. An alternative is to mix (dilute) it with biosolid sludge.
After this has occurred, and the appropriate polymer has been matched to it, the sludge can be pumped through a Insta-Mix®, Poly Mate® or Lime Mate® Polymer Injection Unit and into a Sludge Mate Container Filter for dewatering.
A Sludge Mate® Dewatering Container Filter is a great part of any liquid hauler’s business model. By dewatering the liquid waste being hauled, both the volume and frequency of trips to dispose of the sludge are greatly reduced. This in turn increases the amount that can be hauled with a set number of vacuum trucks.
The Sludge Mate® Dewatering Container Filter and Poly Mate® Polymer Injection Unit are both excellent components for the wastewater management of dairy wastewater, chicken rendering, fish and squid waste processing, and slaughterhouse wastewater.
Poultry, livestock, and grain runoff in agricultural settings each provide their own unique challenges, but can be dewatered using a Poly Mate® Polymer Injection Unit and a Sludge Mate® Container Filter.
Once matched with the proper polymer and/or other coagulants, the wastewater from Concentrated Animal Feeding Operations (CAFO) can be stored and gradually dewatered for land application in compliance with federal regulations such as National Pollutant Discharge Elimination System (NPDES) Permit, or those set forth by the Environmental Protection Agency.
When using vacuum trucks to haul septic wastewater it can quickly become necessary to remove any sort of potential clogs or jams (inorganics/debris) from the effluent before entering it into any kind of facility.
The Large Debris Strainer® is excellent for removing just these sorts of flushable wipes, rags, rocks, sticks, or stones. It simply connects to the hose coming out of the truck, and filters the effluent through a retractable bar screen contained within its chamber.
The Debris Mate® is the only dewatering container filter with a built-in bar screen. This makes it the perfect solution to a large volume of effluent containing inorganic materials (flushable wipes, sticks, rocks, etc.).
The Self Dumping Hopper® can also deal with inorganic materials, grit, and large debris on a much smaller scale.
