Dewatering Solutions
Spectrum Has The Dewatering Equipment You Need.
Spectrum Dewatering Boxes
Spectrum Water provides dewatering boxes and solids-separation equipment for industrial, municipal, environmental, wastewater, and dredging applications.
Standard dewatering boxes rely on basic gravity drainage through filter media or screens. Spectrum's Turbo Phase Separator is engineered to improve that process with greater internal filter surface area, shorter water travel distance, and better handling of difficult wet solids.
The fleet
Volume, solids type and how often the job repeats decide which one you want.
Large-capacity sludge dewatering container designed with a permanent, reusable filter system instead of disposable filter media. A practical option for wastewater, dredging, and industrial sludge applications where reduced filter replacement, lower disposal costs, and simple solids handling are priorities.
High-performance dewatering unit engineered to improve solids separation and support efficient sludge handling in wastewater, industrial, and environmental applications. Ideal for projects where improved drainage and operational flexibility are important.
Turbo Phase SeparatorThe Spectrum Turbo Phase Separator with dump stand is a gravity-based sludge dewatering system designed to separate liquids from solids efficiently while simplifying material handling and unloading.
Where it fits
The Turbo Phase Separator provides a large internal filter surface area, helping reduce dewatering time and improve drainage performance.
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.
Where it fits
Run with Turbo Phase Separators, this is the pairing that produces roughly 2X the dry tons per haul — on gravity alone, with no energy input and fewer trips down the road.
A compact dewatering hopper designed for smaller sludge, slurry, and wet-solids applications. Liquid drains through the filter system while solids remain in the hopper for easier handling, transport, dumping, or reuse.
Where it fits
A practical option for wastewater, dredging, process solids recovery, and other applications where simple gravity dewatering is needed without using a larger roll-off container.
From 15 yd³ to 40 yd³, with optional heating coils, corrosion resistant liners and vacuum assist.
Where it fits
Each box is modeled in SolidWorks® to confirm payload, axle loading and drainage performance before steel is cut.
Standard versus engineered
A standard dewatering box is a practical choice for many sludge, slurry, sediment, and wet-solids applications. Material is loaded into the container, liquid drains through filter media or a screen, and solids remain in the box for handling, transport, or disposal.
This approach is simple and effective, but performance can be limited by available drainage area, filter loading, debris, solids characteristics, and how far liquid must travel before exiting the box.
Built to spec
Custom boxes are engineered in Spectrum's own shop, with each unit modeled in SolidWorks to confirm payload, axle loading and drainage performance before fabrication starts. Optional heating coils, corrosion-resistant liners and vacuum assist cover the streams a standard unit will not handle.
Inside the fabrication shopYes — the fleet is available for short-term rental, outright sale, or build-to-spec fabrication. Rental is the usual answer for a one-off cleanout or a dredging project; purchase makes sense once a stream runs continuously.
From 1–5 cu. yd. fixed filter hoppers up to 40 cu. yd. roll-off filters. The 20 cu. yd. Turbo Phase Separator and the 30 cu. yd. Permanator are the two most requested units.
The filter system. A Permanator uses a permanent, reusable filter rather than disposable filter media, which on a high-volume repeat duty removes what would otherwise be the dominant consumable cost.
Yes, in Spectrum’s own shop. Options include heating coils, corrosion-resistant liners, vacuum assist, dryer decks, specialty screen cloth and integral polymer injection. Each box is modeled in SolidWorks to confirm payload, axle loading and drainage performance before steel is cut.
If you want them. Spectrum can supply boxes alone, or run the whole dewatering operation as a service — crews, polymer chemistry from the in-house lab, boxes and haul-off — under a single contract.
Four buckets, one call
Water, Environmental, Carbon, and Equipment run as one team under one contract — so you brief a single crew and get an answer, not a referral.
