Right-Sized Water Treatment Solutions for Complex Environmental Projects
Brennan provides water treatment for remediation, dredging, dewatering, industrial sites, sediment projects, and water-based construction work.
Built To Treat the Water Your Project Generates Water Treatment Services
Environmental and remediation projects often generate water that must be treated before discharge, reuse, or disposal. That water may come from dredging, dewatering, sediment processing, excavation, containment areas, contact water, stormwater, groundwater, industrial ponds, or other project activities.
Brennan designs water treatment systems around the specific needs of each project. We evaluate contaminants of concern, flow rates, site constraints, discharge requirements, redundancy needs, and production goals to develop a treatment approach that fits the work.
Our portable equipment inventory allows us to right-size each system, from compact mobile water treatment setups to larger integrated systems that support high-production remediation and dewatering projects.
Portable, Scalable Systems Designed Around Your Site Areas of Focus
Brennan provides water treatment services that can be integrated with dredging, dewatering, material separation, environmental remediation, and marine construction. We help clients manage water quality from planning through operation, monitoring, and final discharge.
Portable Systems for Temporary, Remote, and Changing Site Conditions Mobile Water Treatment
Not every project can support a fixed treatment plant. Brennan’s mobile water treatment capabilities allow us to support projects in remote areas, constrained sites, industrial facilities, temporary work zones, and locations where treatment needs may change as the project progresses.
We can mobilize, assemble, operate, and adjust portable water treatment systems based on site-specific needs, production rates, and discharge quality requirements.

Brennan designs, assembles, and operates water treatment systems with the capacity and redundancy needed to maximize production rates and maintain discharge quality.
Our experienced, licensed operators continuously monitor treatment performance and apply the appropriate treatment techniques to help maintain strict water quality standards. This hands-on operational approach allows Brennan to make informed adjustments as site conditions, contaminant concentrations, and flow rates change.
Key Capabilities
- Water treatment system design
- Treatment system assembly
- Treatment system operation
- Capacity planning
- Redundancy planning
- Production-rate support

Treatment for a Wide Range of Environmental & Industrial Constituents Contaminants of Concern
Environmental water treatment projects often involve more than one contaminant. Brennan’s systems can be designed to treat a wide range of constituents depending on project conditions, discharge standards, and site-specific water chemistry.
Contaminants We Treat
- Per- and polyfluoroalkyl substance (PFAS)
- Benzene, toluene, ethylbenzene, and xylene
- Heavy metals
- Oil and grease
- Polychlorinated biphenyls (PCBs)
- Polyaromatic hydrocarbons
- Semi-volatile organic compounds
- Total suspended solids
- Volatile organic compounds
- Additional project-specific contaminants
The Right Equipment for the Right Treatment Challenge Portable Water Treatment Equipment
Brennan maintains a large inventory of portable water treatment equipment, giving our teams flexibility to configure systems around each project’s contaminants, flow rates, solids loading, space constraints, and discharge requirements.
This equipment inventory allows Brennan to build practical treatment trains for complex project conditions instead of forcing a site into a one-size-fits-all setup.
Equipment May Include
- Bag filters
- Granular activated carbon
- Inclined plate clarifiers
- Mix tanks
- Settling tanks
- Storage tanks
- Multimedia filters
- Oil water separators
- Polymer systems
Integrated Treatment for Process Water, Decant Water, and Effluent Water Treatment for Dredging & Dewatering
Water treatment is often closely tied to dredging, dewatering, and material separation. As sediment is removed, processed, and dewatered, water must be managed carefully to protect the site, meet discharge requirements, and maintain production.
Brennan integrates water treatment with the broader project workflow. This helps clients avoid disconnects between dredging, dewatering, treatment, monitoring, and disposal.
Key Capabilities
- Industrial water treatment
- Decant water treatment
- Contact water treatment
- Effluent treatment
- Geotextile tube dewatering
- Mechanical dewatering systems
- Treatment for confined disposal facilities
- Treatment for dredged material processing
- Turbidity control
- Integration with material separation systems
Treatment Planning for Emerging Contaminants PFAS Water Treatment Support
PFAS treatment requires thoughtful planning, careful media selection, and strong system monitoring. Brennan supports projects involving per- and polyfluoroalkyl substances through water treatment systems designed around site-specific water chemistry, contaminant concentrations, discharge criteria, and operational needs.
Because PFAS treatment can be affected by co-contaminants, solids, organic matter, and flow variability, Brennan evaluates the full treatment train to help improve performance and protect downstream treatment media.
Key Capabilities
- PFAS treatment support
- Granular activated carbon treatment
- Pretreatment for solids and turbidity
- Treatment train planning
- Media performance support
- Flow and loading evaluation
- Monitoring and system adjustment
- Project-specific discharge support
Treatment for Industrial & Legacy Site Conditions Oil, Grease, and Petroleum-Related Water Treatment
Industrial and remediation projects may involve water impacted by oil, grease, fuel-related compounds, or petroleum constituents such as BTEX and VOCs. Brennan configures treatment systems to address these conditions while supporting project flow rates and discharge quality goals.
Key Capabilities
- Oil and grease treatment
- Oil water separation
- BTEX treatment support
- VOC treatment support
- Industrial water treatment
- Treatment for MGP and legacy industrial sites
- Pretreatment and filtration

Clearer Water Through Practical Solids Management Solids, TSS, and Turbidity Control
Total suspended solids and turbidity are common water quality concerns on dredging, dewatering, remediation, and construction projects. Brennan uses filtration, settling, clarification, polymer systems, and other treatment techniques to remove solids and improve discharge quality.
By managing solids early in the treatment process, Brennan helps protect downstream equipment, improve treatment performance, and support compliance with discharge requirements.
Key Capabilities
- Total suspended solids treatment
- Turbidity reduction
- Clarification
- Settling
- Filtration
- Polymer system support
- Bag filters
- Multimedia filters
- Inclined plate clarifiers

Testing That Helps Build a Better Treatment System Treatability Testing & Treatment Optimization
The most effective water treatment systems begin with a clear understanding of the water being treated. Brennan can pair water treatment planning with treatability testing to evaluate contaminants, solids, chemistry, filtration needs, chemical treatment options, and treatment media performance before full-scale implementation.
This helps project teams select the right equipment, reduce uncertainty, improve cost predictability, and build a treatment system that fits the actual conditions on site.
Key Capabilities
- Industrial wastewater treatability studies
- Chemical treatment evaluations
- Polymer optimization
- Turbidity and TSS testing
- Media selection support
- Treatment process comparison
- Full-scale system planning
- Field optimization support
