The Smart Sponge® advantage

Meet Today’s Requirements Without Limiting Tomorrow’s Options.

As water quality requirements become more complex, you need treatment that goes beyond sediment control. Smart Sponge® targets priority contaminants while supporting high flow rates, reducing maintenance demands, and fitting into both new and existing infrastructure.

Passive operation

Treat stormwater and other water flows without pumps, power, or complex mechanical equipment.

Designed for new systems and retrofits

Specify Smart Sponge® in new infrastructure or integrate it into existing catch basins, vaults, outfalls, pressure vessels, and treatment systems.

Built to evolve

Change or combine media as contaminants, site conditions, regulations, or treatment goals change, without replacing the entire system.

No backwashing required

Eliminate the water use, equipment, and operational demands associated with backwashing.

High flow. Low maintenance.

The high-porosity structure supports high flow rates while helping reduce clogging, cleaning, and maintenance demands.

Lower disposal and lifecycle costs

Low moisture retention reduces spent-media weight and associated handling, transportation, and disposal costs compared with traditional high-moisture retaining media.

Targeted Contaminant Treatment

Match the Media to Your Water Quality Priorities.

Every site has a different mix of contaminants, flow conditions, and discharge requirements. Smart Sponge® media can be selected and combined to address multiple treatment objectives within a single system.

Sediment & TSS

Targets suspended solids and sediment through a high-porosity structure designed to capture particulates while maintaining flow and reducing maintenance demands.

Smart Sponge®

Hydrocarbons & oil

Captures oil, grease, and hydrocarbons that contribute to sheens and degraded water quality.

Smart Sponge®

Heavy metals

Targets lead, mercury, arsenic, chromium, zinc, copper, and other metals using contaminant-specific media.

Smart Sponge® HM

Nutrients

Helps reduce nutrient loading associated with harmful algal blooms and impaired waterways.

Smart Sponge® HM

Total Organic Carbon (TOC)

Adsorbs dissolved and suspended organic compounds that contribute to elevated TOC, helping improve water quality and support discharge and treatment objectives.

Smart Sponge® AC

Bacteria

Targets E. coli and coliform to support safer discharge and receiving-water quality.

Smart Sponge® Plus

PFAS

Engineered to capture per- and polyfluoroalkyl compounds from contaminated water.

Smart Sponge® Quanta™

Our Approach

Every Solution Starts with Your Site, Not Our Product.

Assess

We evaluate your site, water quality, objectives, regulatory requirements, and existing infrastructure to determine the most effective treatment approach.

Select

We identify the Smart Sponge® media or media combination best suited to the contaminants present and recommend the optimal deployment method.

Install

Smart Sponge® integrates into new or existing infrastructure with minimal disruption and peak flexibility, helping extend the life of existing assets while improving treatment performance.

Validate

We confirm performance through laboratory testing, pilot programs, and real-world operating data to ensure reliable, long-term results.

“The inserts dropped straight into our existing basins and cleared our permit targets — with far less maintenance than the media we replaced.”
