Solids Separations

Solids Separations

Veolia North America has extensive experience in processing, separating and reducing all types of waste streams to help your company minimize waste volume, recover usable materials, reduce disposal costs and lower long-term liabilities. We can offer you the right solution for your project’s size and material processing requirements, and perform the work in accordance with the most stringent safety protocols.
 

CUSTOMIZED SOLIDS SEPARATIONS SERVICES

Veolia approaches each project with a customized process and technical recommendations to address your specific sludge stream with maximum efficiency and cost-effectiveness. This includes an initial analysis of all relevant factors, such as sludge properties, chemical interactions, logistics, objectives and regulatory compliance.

We offer a broad range of solids separation services, including dredging and pumping, dewatering, and tank cleaning and processing. We can help your enterprise:
  • Minimize hazardous and non-hazardous waste volumes
  • Meet paint filter test disposal requirements
  • Recover valuable products such as oil, water and metals
  • Enable beneficial reuse and recycling 
  • Restore storage and settling capacity

INNOVATIVE AND INDUSTRY-LEADING SOLIDS SEPARATION TECHNOLOGIES

We’ve found the key to success in solids separation is to evaluate all chemical and mechanical options based on cost-effectiveness and their compatibility with your goals. We use advanced technologies to create a process and equipment line-up that matches your requirements.
 

PROCESS UNITS/DEWATERING

Choosing the right mechanical technology and combination of equipment is vital to solids separation success. Our experts will help you design the right process for your specific sludge stream situation.

Centrifuge
Veolia owns a fleet of skid-mounted centrifuges in a variety of sizes, “G-force ratings” and flow capacities, with a number of adjustments to maximize results for specific sludge streams.
  • High centrifugal forces of up 2,500 rpm, or about 2.8 Gs, separates sludge streams.
  • Advantages include light labor requirements and highly effective solids separation.
  • This technology is best suited for oil-water-solid and latex sludge streams.

Belt Press
Veolia owns a fleet of trailer- and skid-mounted belt press units in various sizes.
  • Treated sludge is rolled and spread across a special belt that initially separates liquids, and then the material is squeezed in a series of belts and rollers for further separation.
  • Advantages include light labor needs, high capacity and a durable, reliable operation.
  • Belt presses are ideally suited for bio-solids and primary and secondary digested sludge.

Filter Press
This technology is capable of dewatering a wide variety of sludge streams.
  • This high-pressure technology uses a series of recessed chambers, plates and frame presses to get the driest filter cakes (solids) possible.
  • Advantages include waste volume reduction, reduced costs (compared to other methods) and dependable and durable operation.
  • This technology is best suited for metal hydroxide, metal oxide, carbon or coal, fly ash, lime and mill scale streams.

Woven Fabric Dewatering
This low-tech and basic method may be suitable for some applications.
  • Tubes are filled to consolidate materials and refilled, with this cycle continuing until the capacity has been reached with consolidated solids.
  • Advantages include very low costs (compared to other methods) and light labor needs.
  • This technique is best suited for a variety of applications, such as sediment and lagoon sludge streams.

OTHER SOLUTIONS

Sludge Dredging and Pumping
Manned and remotely-operated dredge platforms and a variety of submersible pumping equipment are available for dredging sludge from ponds and lagoons. A variety of booms and other equipment can help meet virtually any dredging need.

Tank Cleaning
Our experienced crews and proprietary technology are capable of safely cleaning almost any type of tank to extract sludge material for separation or disposal. These include crude, fuel and slop oil, asphalt, wastewater, gasoline, sour water and benzene tanks.

Dryer Technology
This equipment is used to remove additional water and organic constituents from centrifuge or filter press cakes to maximize the volume reduction of hazardous and other waste streams. The addition of a thermal dryer can reduce overall waste volume by up to 98%.

Full-Service Treatability Lab
Our lab experts and resources can help evaluate the cost-effectiveness and likely results of using different types of separation technology. This includes the use of certain types of chemical and their effectiveness.

Long-Term, On-site Processing
We can help plan, design and build a long-term processing facility at your site in order to maximize the beneficial reuse of waste stream. Each process is designed specifically for your sludge stream and waste management or product recovery objectives.

COMPLIANCE

Veolia maintains a proven record of compliance with health, safety, and environmental regulations. We can help:
  • Ensure that the handling, transport, recycling, reuse and disposal of all waste products meets state and federal regulations
  • Protect against liability

Veolia's solids separation services:
  • Meet or exceed the standards set by the Federal Resource Conservation and Recovery Act (RCRA)
  • Comply with NPDES/POTW Discharge Permits
