Spectrum Wastewater Equipment Solutions

Rent it, buy it, or have it built to spec

Spectrum provides a full suite of field proven equipment — available for short term rental, standard off the shelf sale, or custom build to spec fabrication — so industrial, municipal and environmental operators can keep projects on schedule and plants in compliance.

Every unit is supported by Spectrum's onsite technicians and process chemists, giving clients the expertise they need to achieve maximum uptime and lowest total cost of ownership.

Rental Fleet

Rental Fleet

When the duty is temporary, the equipment should be too.

Blue Turbo Phase Separator dewatering box with its rear door open, showing the internal stainless screen wall

Turbo Phase Separator

Patented roll off container with an internal stainless steel screen; boosts drainage area by 33% and roughly doubles the dry tons per haul, on gravity alone.

Where it fits

Emergency bypass, surge-tank dewatering and pipeline pigging projects that demand drier cake and fewer landfill trips.

Turbo Phase Separator
Two fast-flow end dump trailers rigged with drain hoses, dewatering on site

End Dump & Fast Flow Trailers

Fast-flow end dump trailers that keep draining all the way to the gate. Paired with Turbo Phase Separators, each load carries roughly twice the dry tons of typical dewatering.

Where it fits

Hauling campaigns where disposal is billed by weight, so every gallon drained on site comes off the invoice.

Sludge dewatering
Blue skid-mounted mobile clarifier with cone bottoms and elevated catwalk in the fabrication shop

Mobile Clarifiers

Trailer and skid mounted clarifiers that settle solids ahead of downstream polishing, delivered with drive and skimmer installed.

Where it fits

Temporary settling capacity during outages, upgrades or seasonal peaks.

Clarifiers
Stainless mobile DAF unit loaded on a lowboy trailer in the fabrication shop

Mobile DAFs

Trailer and skid mounted DAF units from 50 to 1,000 gpm for FOG and TSS removal, delivered plug-and-play with chemical feed integrated.

Where it fits

Bypass and pretreatment duties that need flotation capacity without a capital project.

DAF units
Pontoon dredge working across the surface of an industrial lagoon

Dredging Packages

Skid or trailer mounted pumps, screens and hydro cyclones for removing accumulated solids from lagoons, ponds and basins.

Where it fits

Rapid, temporary sludge removal ahead of plant upgrades or capacity restorations.

Dredging services
Two dark green Spectrum activated carbon pressure vessels standing in the yard

Carbon Vessels

Rental pressure vessels pre charged with virgin or reactivated GAC for polishing organics, PFAS or trace hydrocarbons.

Where it fits

Temporary treatment while permanent GAC trains are changed out or when unexpected contaminants appear.

Wheel loader carrying timber mats across a composite mat roadway

Mats

Heavy duty composite or hardwood mats rated for cranes and dredge traffic.

Where it fits

Protects wetlands and liner covered cells during dredging or tank cleanout work.

Standard OEM Sales

OEM Sales (Standard Models)

Pre-engineered models ship faster than field-erected equipment and arrive substantially complete.

End Dump / Fast Flow Trailers

Open top trailers with recessed drainage screens that keep dewatering the load in transit, so water is still leaving the material on the way to the gate.

Spectrum advantage

The other half of the pair nobody else runs. Matched to Turbo Phase Separators, the trailer is what turns a drier cake into roughly twice the dry tons per haul — and it does it on gravity, with no energy input and no extra truck.

Compact DAF Units

Remove FOG and TSS in food, pulp & paper, or refinery wastewater; trailer or skid options for 50–1,000 gpm.

Spectrum advantage

Delivered plug and play with chemical feed integration for rapid commissioning.

DAF units

Circular Clarifiers

Gravity settling of primary or secondary sludge; steel or FRP construction.

Spectrum advantage

Pre engineered sizes ship faster than field erected units and arrive with drive, scum skimmer and walkway installed.

Clarifiers

Carbon Trailers

Tandem axle mobile GAC contactors for rapid deployment to remote well fields or remediation sites.

Spectrum advantage

Built in flow splitting manifolds eliminate external piping and reduce set up time.

Polymer Blending Skids

Fully automated dry and liquid polymer activation systems that deliver consistent, hydrated solution to DAFs and presses.

Spectrum advantage

Factory wet tested, skid mounted and sized for your target solids load.

Ancillary Items

Industrial hoses, diaphragm transfer pumps, inline mixers, scrubbers and cartridge or bag filters can be packaged with any main line equipment for a true one call solution.

Turbo Phase Separators® — Custom

Added dryer decks, specialty screen cloth and integral polymer injection give even lower cake moisture, extending box duty cycles and cutting landfill trips. Clients also gain direct access to Spectrum’s process chemists for bench testing and start up support.

Turbo Phase Separator

Dewatering Boxes & Roll Off Filters

From 15 yd³ to 40 yd³, with optional heating coils, corrosion resistant liners and vacuum assist. Each box is modeled in SolidWorks® to confirm payload, axle loading and drainage performance before steel is cut.

The shop

Our own shop, our own steel

Custom units are engineered and fabricated in Spectrum's own bays, which is what makes build-to-spec routine rather than exceptional. Each box is modeled in SolidWorks to confirm payload, axle loading and drainage performance before steel is cut — and the process chemists who specify the chemistry work in the same building as the welders.

Site Ready Modules & Spares

Site Ready Modules & Spares

The connections, mixers and filters that turn separate units into one working train.

Hoses & Pumps

Chemical resistant, 1–4 in.

Mats

Crane, excavator and pipeline crossings.

Mixers (Static Mixers)

316 SS, low pressure loss for flash neutralization.

Scrubbers

Packed bed or mist eliminator designs for H₂S and acid gases.

Filters

Cartridge, bag or deep bed media housings in poly, FRP or steel.

Oil–Water Separators

Coalescing and gravity separators that pull free and dispersed oil off the stream before it reaches carbon or biology.

Dewatering fleet

The largest fleet of dewatering boxes in the world

From 1–5 cu. yd. fixed filter hoppers to 30 cu. yd. Permanators with a permanent reusable filter system, the fleet covers routine gravity dewatering and the difficult streams that defeat a standard box — material with lumps, chunks, trash or debris that cannot easily be pumped.

Who Spectrum works for

Refineries, chemical plants, terminals and mills run Spectrum equipment — most of them on recurring site contracts rather than one-off jobs.

FAQs

Can I rent rather than buy?

Yes — the same equipment is available for short-term rental, off-the-shelf sale or custom build-to-spec fabrication. Which one makes sense usually comes down to how long the duty lasts and whether the stream is going to change.

How long does a build-to-spec unit take?

Every box is modeled in SolidWorks to confirm payload, axle loading and drainage performance before steel is cut, which is what keeps the schedule honest. Pre-engineered sizes ship considerably faster than field-erected units. Send the duty and we will give you a real date.

Is there support after the equipment arrives?

Every unit is backed by Spectrum technicians and process chemists. Clients building to spec also get direct access to the process chemists for bench testing and start-up support — the point of the model is that the hardware and the chemistry come from the same people.

What sizes do the dewatering boxes come in?

From 1–5 cu. yd. fixed filter hoppers up to 40 cu. yd. roll-off boxes, with optional heating coils, corrosion-resistant liners and vacuum assist. The 20 cu. yd. Turbo Phase Separator and the 30 cu. yd. Permanator are the two most requested.
