What would I use to dewater storm drain or lift-station waste?

The Debis Mate® is a ready-made solution to dewatering large amounts of large solids such as rags, sticks, branches, rags, and flushable wipes before they enter the headworks of the plant.

What would I use to dewater grit or sand?

A round-bottom, roll-off container filter dewaters grit, sand, and other fines without blinding off. It is a straight-forward solution to removing excessive grit from wastewater before entering the headworks of a plant.

What does TDS mean?

Total Dissolved Solids— this is a combination of all of the colloidal or charged solids in a volume of water. Essentially it is all of the solids that are emulsified/molecularly bonded to the water.

What does TSS mean?

Total Suspended Solids—these are the solids in water that can be trapped by a filter.

What is the difference between a Sludge Mate® Dewatering Container Filter and a regular Roll-Off Dewatering Container Filter?

A Sludge Mate® Dewatering Container Filter has filters on the walls and on the double-walled center panel, but not on the floors. The smooth floor allows for rapid draining through its additional drainage ports. These solid steel floors also allow the sludge cake to slide out easily when dumping.

What kind of container filter is right for fine solids or inorganic/non-emulsified wastewater?

In small quantities a Self-Dumping Hopper will suffice. When larger quantities are being dewatered, a round-bottom roll-off container filter is necessary.

What style of container filter is right for bio solids?

The Sludge Mate® is the only dewatering container filter designed specifically for bio solids. With its additional drainage ports, smooth floors, and side walls that form a right angle with the floor, it is the easiest dumping container filter available. Sludge cake slides out readily in a solid chunk, making maintenance as simple as hose and go.

What kinds of sludge can be processed with a container filter?

With a round-bottomed roll-off container, all inorganic solids can be settled and dewatered.

With the addition of a Poly Mate® or Insta-Mix® Polymer Injection Unit and dewatering polymer you can readily dewater aerated bio solids.

With an additional mixing tank and dewatering chemicals such as ferric, alum, or lime you can readily dewater grease trap waste and nearly any other kind of wastewater.

How much material can be processed at a time through a Sludge Mate® or container filter?

Based on 1 to 1 ½% solids, you can process 1,000 gallons per cu yd. For example, a 15 cu yd will process 15,000 gallons, a 20 cu yd will process 20,000 gallons of 1 to 1 ½% solids sludge.

How dry will the sludge get in the box?

After letting it sit for around 24 to 48 hours in the box (depending on the nature of the sludge), it will get up to around 12 to 15% solids, which passes the paint filter test and coffee filter test at the landfill. The longer you let it sit in the box, the dryer it will get.

Why do I need polymer for digested sludge, alum, septic and other bio-solids waste?

Polymer helps the solids flock and release the clean, free water. Polymer is the constant required addition for all dewatering; including dewatering containers, belt press, centrifuge, to ensure the quick release of free water.

What if I need a custom size dewatering box to fit a certain footprint at the job site?

We can help with that! Flo Trend® custom builds all equipment matching any required data. After receipt of purchase order, we will prepare a drawing that will be sent out to you for approval. We do not begin building until you have signed and sent back the drawing.

Do you make dewatering containers designed for sludge that does not need polymer, such as vac truck waster, grit/sand, Stormwater, etc?

Yes we do! For this type of sludge, you need a container with filter media on the bottom, sides and back wall. We have disposable liners available that are custom sewn to fit on top of the permanent filter media, which allows for more versatility with dewatering. The liner is biodegradable and will dump out at the landfill or disposal site with the sludge.

Can the effluent be dumped on the ground for disposal?

No. Even though the filtrate appears very clear, it is still non processed water and still needs to be returned to treatment.

Do you provide start up assistance?

Yes, we do! For an additional cost, we can provide an FTS technician for (2) 8 hour days of startup assistance. He will walk you through the steps necessary to ensure you have a proper floc with the polymer and end with an optimum dewatering result. *Please wait until sludge is available on site to process before scheduling.

Is there a warranty on the equipment?

Yes! We provide a one-year warranty on the dewatering container and 5-year warranty on the filter media with normal use. Please ask a sales associate for further details.

Around how much polymer is needed?

Polymer is around $35 per gallon. (It will cost around $140 to treat 30,000 gallons of sludge). Contact us here for exact pricing or to place an order.

How much does polymer cost?

Polymer is around $35 per gallon. (It will cost around $140 to treat 30,000 gallons of sludge)

What size plant will make it efficient to use a Sludge Mate®?

The Sludge Mate® is a perfect fit for a 1 ½ mgd and less plant.

What is the minimum % solids that you can process through a Sludge Mate®?

The sludge needs to be at least .9% solids to dewater well. If it is less than .9%, you will want to thicken it up before processing. Please ask a sales representative for more details by calling 1.800.762.9893 or filling out our contact form.
