Stop Shipping Water: Revolutionize Lagoon Dredging with SLUSORB
Turn Liquid Sludge into Haulable Solids in Minutes—Not MonthsDrastically reduce disposal costs, protect your lagoon liners, and pass the EPA Paint Filter Test instantly.
Save on Transportation Costs
Since the treatment does not increase volume or weight, you can use standard dump trucks instead of costly vacuum tankers, significantly improving hauling efficiency.
Compliance & Environmental Safety
The solidified material does not leach and passes the Paint Filter Test, meeting landfill acceptance standards.
Protect Your Assets
Cleaning can be performed without draining the entire lagoon, and the polymer is non-corrosive, ensuring no damage to valuable clay or synthetic liners.
Overview
SLUSORB Polymer technology locks moisture and solidifies lagoon dredging sludge, converting high-water-content slurry into stackable solids within minutes. Rapid absorption and chemical cross-linking minimize free liquids while protecting liners and reducing transport volume and cost.


The Challenges
You Are Paying to Haul 90% Water.
Whether its a municipal wastewater plant, an industrial settling pond, or an agricultural lagoon, sediment removal is a logistical questions.
-Exorbitant Hauling Costs: Vacuum trucks are expensive. hauling liquid sludge means you are paying to transport water.
-Landfill Rejection: Most landfills reject liquid waste that fails the Paint Filter Test.
-Inefficient Bulking Agents: Traditional methods like sawdust or wood chips increase waste volume by 100-200%, doubling your truckloads.
-Risk to Infrastructure: Lime and cement are heavy, alter pH, and generate heat (exothermic reaction) that can melt or damage expensive HDPE liners.


Key claims

Absorption capacity: 200–300× water by weight (dependent on sludge composition)

Dosage: typically 0.5%–1.5% by weight

Solidification: minutes to hours; often shovel‑ready in 15–30 minutes

Volume increase: negligible (< 1%)

Weight: does not add significant weight

Liner compatibility: non‑exothermic, non‑corrosive; safe for HDPE and clay liners

Regulatory: engineered to pass EPA Paint Filter Liquids Test (PFLT); TCLP performance where indicated

How it works

Pumping/Dredge: transfer sediment to the mixing zone or mix in situ

Mixing: add SLUSORB at a low ratio (typically 0.5%–1.5% by weight); simple mixing equipment is sufficient

Solidify: polymer cross‑linking locks in moisture; treated material shows no free liquid and passes the Paint Filter Test

Features comparison

Volume increase: SLUSORB — negligible (< 1%); Sawdust/Corn cobs — massive (> 100%); Lime/Cement — moderate (20–50%)

Curing speed: SLUSORB — minutes; Sawdust/Corn cobs — slow; Lime/Cement — days/weeks

Liner safety: SLUSORB — safe (no heat); Sawdust/Corn cobs — generally safe; Lime/Cement — high risk (exothermic)

Weight added: SLUSORB — none; Sawdust/Corn cobs — adds weight; Lime/Cement — significant weight

EPA compliance: SLUSORB — passes PFLT/TCLP where indicated; alternatives — variable

Applications

Mechanical dredging sludge management (excavation and suction operations)

Hydraulic dredging slurry treatment (high-water-content pipeline/pump systems)

Dewatering bag and flocculation integration to accelerate solid capture and drainage

Emergency response: immobilization of spills to prevent runoff and simplify cleanup

Ecosystem restoration and beneficial reuse: wetland restoration, island construction, slope stabilization, structural backfill

FAQs (selected)

Suitable range: effective on a wide range of water‑based dredging materials; performance varies with solids content and ionic strength

Advantages vs traditional dewatering: faster solidification, reduced free water and leachate, lower hauling/disposal costs, contaminant stabilization

Typical dosage: 0.5%–1.5% by weight depending on sludge composition

Solidification time: reaction begins immediately; material often transportable within 15–30 minutes

Liner safety: reaction is non‑exothermic and non‑corrosive; does not damage HDPE or clay liners

Landfill acceptance: formulated to meet EPA Paint Filter Liquids Test (PFLT) requirements
