Sludge Thickening for Primary and Waste Activated Sludge (WAS)

THK Series sludge thickener is specifically engineered to achieve high-performance biosolids thickening. The THK uses 50% less power than standard dewatering centrifuges, is simple to operate with minimal operator attention, and has the industry's lowest total cost of ownership. 

• Proven no polymer performance

• Enclosed system reduces odors and gases

• Hygienic operation and safety for operators

• Doubles the solids retention time in the digester or doubles the digester capacity

• Reduces digester heat requirements by 50%

• Provides the greatest G-volume from the all cylindrical/no conical design, compared to other decanter centrifuges of similar bowl diameter

• Optimization is simple with basic tuning (independent control of liquids weir and solids weir) and fine-tuning (patented hydro-pneumatic control maintains solids to digester

• Smallest footprint efficiently utilizes available plant space

• Reduce installation costs by 35-50% ($/gpm)

Hydrolysis Process: PONDUS™ (THP) Improves Digester Performance 

PONDUS is a low-grade heat (140 °F to 160 °F) process that significantly helps your plant generate biogas, increases digester space, and reduces disposal costs. Easy to maintain, your operators can operate PONDUS without additional training certifications and perform all required maintenance.

• Increase solids loading rates to the digester

• No steam or pressure vessel required

• Improve thermal energy balance

• Increase biogas production up to 30%

• Reduce biosolids disposal costs up to 30%

• No polymer is required for sludge thickening prior to hydrolization

Dewatering for Cost-Effective Biosolids Disposal

CS Series Dewatering Centrifuge is the most efficient decanter centrifuge in the industry. It’s designed and built from what was learned in the field by servicing competitors' dewatering equipment in both municipal and industrial applications. The CS can provide an ROI in as little as 1.5 years and reduce maintenance and operating costs.

• Rotodiff^® hydraulic backdrive—the most efficient in the industry

• Lowest measured energy consumption*

• Highest torque to weight ratio with 100% torque at all speeds

• Increase solids loading capacity

• Reduce polymer consumption

• Continuous operation

• Lowest installed horsepower compared to a gearbox of similar torque

• Reduce disposal costs with the driest cake

• Advanced wear protection prolongs centrifuge life, increases uptime, optimizes performance and reduces service and maintenance costs

• Customizable for unique application requirements

High-Efficiency Phosphorus Recovery and Removal as Brushite

CalPrex^® minimizes digester and sidestream phosphorus loading by over 50%, greatly reduces tedious plant maintenance, and removes or recovers phosphorous as a brushite crystal.

• Reduce disposal costs up to 50%

• Divert over 70% of the soluble P from the digester

• Reduce up to 50% of the total P in biosolids

• Reduce struvite buildup in the digester

• No ammonium required

• Recover brushite as a valuable fertilizer

Phosphorus Recovery and Removal for Struvite Management 

MagPrex™ is the most cost-effective solution for struvite treatment. The MagPrex™ phosphorous management process gives all-sized plants an affordable option to reduce phosphorus recycle loads and eliminate struvite precipitation and formation.

• Improve sludge dewaterability

• Reduce polymer consumption up to 30%

• Reduce disposal costs up to 20%

• Reduce phosphate recycle load up to 90%

• Reduce maintenance costs up to 50%

• No sodium hydroxide required

• Reduce struvite precipitation by harvesting (struvite recovery for reuse) or sequestration (struvite removal through the sludge)
