Dewatering Applications

Proven Separation Performance Across Every Industry
 

From municipal wastewater facilities to high-grade hygienic processing, separation demands vary radically by application. Backed by decades of hands-on engineering, HILLER centrifuge systems are field-proven across a vast range of dewatering and liquid-solid separation processes.

Whether you need high-solids capture in municipal sludges, hygienic precision in food and beverage production, or aggressive phase separation in waste oil recovery, our systems are tailored to optimize your yield and minimize operational costs.

Municipal Sludge Dewatering

The proven industry benchmark for maximum cake dryness and lower lifecycle costs. When evaluating municipal wastewater sludge dewatering—whether primary, WAS, digested, or mixed sludges—independent industry studies consistently rate high-G decanter centrifuges as the clear winner over belt presses, screw presses, and filter presses. Centrifugation provides unmatched volumetric throughput, superior solids capture, and the highest cake dryness available on the market. Why High-G Centrifugation Outperforms Other Technologies: Industry-Leading Cake Dryness: Generates high centrifugal force to extract maximum bound water—significantly cutting daily hauling, landfill tipping fees, and incineration costs. Proven Overall Lowest Lifecycle Cost: Higher initial efficiency, continuous automated operation, and reduced chemical demand make centrifuges the most cost-effective long-term investment. Compact, Fully Enclosed Design: Operates within a fraction of the floor space required by belt presses while completely containing odors, aerosols, and mess. Continuous 24/7 Automated Processing: Modern Allen-Bradley controls dynamically adjust to varying feed solids, maintaining peak performance without constant operator intervention.

DAF Sludge Dewatering

High-G Centrifuge Dewatering for DAF Sludge Turn wet DAF float into a dry, manageable cake.DAF systems are excellent for clarifying wastewater, but the resulting float contains vast amounts of trapped water. Processing DAF sludge through a high-G decanter centrifuge unlocks maximum volume reduction, turning a costly liquid disposal challenge into an efficient, dry solids handling operation. Why High-G Centrifugation Works for DAF Sludge: Superior Force for Difficult Solids: Generates thousands of Gs to easily separate low-density grease, oils, and biological flocs. Massive Volume & Cost Reduction: Drastically cuts truckloads and tipping fees by stripping out free and bound moisture. Compact Footprint: Handles high GPM throughput in a fully enclosed, compact unit compared to expansive press systems.

Food & Beverages - Juices, Purees, Concentrates

Sanitary, high-temperature performance engineered to protect product purity and flavor. From fruit juices, plant-based proteins, and brewing to edible oils and nutraceuticals, food and beverage processing demands absolute hygiene, precise phase separation, and total quality control. High-G decanter centrifuges are built to handle high-temperature CIP (Clean-in-Place) cycles while operating in fully enclosed environments that isolate delicate food products from oxygen, airborne contaminants, and microbial exposure. Why High-G Centrifugation Leads in Food & Beverage Applications: Inert & Oxygen-Controlled Options: Enclosed housing design with centripital pumping prevents oxidation, preserving product fresh color, aroma, and flavor profiles. Sanitary, CIP-Ready Construction: Crafted with high-grade, polished stainless steel and sanitary seals designed to withstand continuous, high-temperature chemical washdowns. High-Yield Phase Separation: High G-force maximizes juice clarity, protein recovery, and oil polishing—delivering maximum product yield with minimal waste. Continuous Processing Without Filter Aids: Replaces diatomaceous earth (DE) and disposable media, eliminating filtration media costs, spent-filter disposal, and batch downtime.

Rendering

Engineered to handle high-fat streams, tough solids, and aggressive liquid-phase separation. Rendering applications—such as poultry, beef, pork, and byproduct processing—present some of the most challenging dewatering conditions in the industry. High grease, fat, and oil contents tend to blind filter media and foul traditional mechanical presses. High-G decanter centrifuges thrive in these sticky environments, delivering clean, sharp phase separation without the risk of media blinding or frequent wash-downs. Why High-G Centrifugation Beats Traditional Systems in Rendering: Blinding-Proof Operation: Unlike belt presses or screw screens that rapidly clog with animal fats and grease, centrifuges use pure G-force—eliminating filter media entirely. Maximum Value Recovery: Efficiently separates valuable tallow, lard, and proteins, allowing you to maximize product yield and reclaim high-purity oils. Superior Cake Dryness & Moisture Reduction: Generates high centrifugal force to shear bound fats and water from meal, reducing downstream drying energy costs. Hygienic, Fully Enclosed Design: Heavy-duty, stainless-steel construction handles high-temperature feeds while containing harsh rendering odors and minimizing wash-down water usage.

Commercial Fryer Operation

Oil & Grease Recovery

Turn waste fry oil, brown grease, and trap grease into high-value, marketable feedstocks. Reclaiming waste fats, oils, and grease (FOG)—such as yellow grease, recycled fry oil, and heavy brown grease from grease traps—requires aggressive 3-phase separation to strip out fine solids and emulsified water. Because these feeds are heavily contaminated, thick, and highly variable, traditional settling tanks and low-G filters simply can't achieve the purity required by biofuel producers and rendering buyers. High-G decanter centrifuges generate the force needed to break tough emulsions and deliver ultra-clean, dry oil fractions in a single pass. Why High-G Centrifugation Superior for FOG Recovery: Sharp 3-Phase Phase Separation: Simultaneously isolates dry solids, clean water, and high-purity oil (down to
