BIOSOLIDS
Biosolids treatment is a critical component of every wastewater treatment process, transforming the solids generated during treatment into a stabilized material that can be safely managed, disposed of, or beneficially reused. Proper handling of biosolids ensures environmental protection, regulatory compliance, and operational efficiency.
Our biosolids systems are designed to meet the unique needs of each facility, integrating proven technologies for thickening, stabilization, dewatering, and conveyance. Whether your goal is to reduce hauling costs, recover energy, or prepare biosolids for land application, we provide flexible and reliable solutions tailored to your process.
TECHNOLOGIES
The ThickTech™ RDT is a high-performance sludge thickener that reduces volume by up to 90% with a 98% capture rate, using minimal polymer, power, and water. Its compact, stainless steel design provides reliable, low-maintenance operation for municipal, industrial, and pulp & paper applications. Ideal for increasing digester capacity, reducing hauling costs, or pre-thickening ahead of dewatering, the ThickTech™ combines a low-shear floc tank with a high-efficiency rotary drum screen, backed by over 25 years of proven performance.

Fluence specializes in anaerobic wastewater treatment, or anaerobic digestion, a biological treatment process that uses microbes to biodegrade organic matter (feedstock) in an oxygen-free tank, treating challenging, high-organic-load wastewater streams and generating valuable products in the process.
Unison Solutions has developed systems that economically produce renewable natural gas (RNG) for injection into natural gas pipelines around the country. By using multiple-stage membranes to remove carbon dioxide and customizing the system to the designated pipeline’s unique specifications, we can produce RNG that meets or exceeds pipeline requirements.
Advanced thermophilic biosolids treatment offers efficient solids reduction and compact design. It achieves over 50% TS reduction and 60–70% VS destruction, while boosting cake solids from mechanical dewatering. The system features process flexibility, low odor, minimal maintenance, and automated control—making it a reliable, high-performance solution for wastewater treatment.
H2Flow Permastore Glass-Fused-to-Steel tanks offer a durable, corrosion-resistant solution ideal for digester applications. Combining the strength of steel with the chemical resistance of glass, these tanks ensure long service life, fast installation, and minimal maintenance—making them a reliable choice for demanding wastewater treatment environments.
The FKC Screw Press is a robust, low-maintenance dewatering solution for municipal and industrial sludge. With heavy-duty construction and stainless steel wetted parts, it delivers high outlet consistency with minimal operator attention. Fully enclosed covers, automated wash-down, and no wearing brushes or squeegees ensure low operating and maintenance costs. Proven, reliable, and efficient, the FKC sets the standard in screw press dewatering.
Anaerobic digester covers are a vital component in the operation of the digester. They not only provide a seal to maintain the anaerobic environment within the tank, but also offer thermal shielding and odour control. In addition, digester covers provide high volume gas storage for recovery and reuse.
Ovivo LM™ Mixers use a unique oscillating motion to efficiently mix over 90% of digester volume with low energy use up to 70% less than traditional mixers. Their ragless design, quick installation, and minimal maintenance make them a cost-effective choice for optimizing anaerobic digestion.
