At ORAIPL, we engineered the OraDredge™ Mobile Sludge Processing Units to tackle sludge challenges right at the source. These systems are modular, portable, and fully adaptable for onsite deployment, eliminating the need for costly transport and offsite treatment.
By integrating advanced Decanter Centrifuges, Screw Presses, and other dewatering technologies, OraDredge™ units enable industries to separate valuable liquids from sludge, recover oils, water, acids, and solvents, and convert waste into dry, compact cakes that are easier and cheaper to handle. Best of all, the entire process runs without disrupting plant operations, giving you a continuous, safe, and sustainable sludge management solution.
Sludge Disposal Challenges
Across industries — from refineries and petrochemicals to fertilizer plants, steel mills, power plants, and wastewater treatment facilities — sludge is a constant by-product of operations. But sludge is not just waste; it often contains valuable trapped liquids like oils, water, acids, and solvents.
The challenges of conventional sludge disposal include:
-
High transport and handling costs due to bulky, wet sludge.
-
Loss of valuable process liquids that remain trapped in sludge.
-
Environmental compliance risks with untreated sludge disposal.
-
Downtime when sludge cannot be processed onsite.
Traditional approaches often involve collecting wet sludge and transporting it offsite, which is both costly and unsustainable.
The OraDredge™ Solution: Mobile Sludge Processing
At ORAIPL, we designed the OraDredge™ Mobile Sludge Processing Units to solve these challenges directly at the source. These units are modular, portable, and built for onsite operation, allowing industries to dewater sludge, recover valuable liquids, and minimize disposal volumes — all without disrupting plant operations.
How It Works
-
Sludge is pumped from tanks, lagoons, or pits via OraDredge™ robotic systems.
-
It is fed into mobile processing units equipped with Decanter Centrifuges, Screw Presses, or Filter Presses.
-
Liquids (oil, water, acids, solvents) are separated and recovered for reuse.
-
Solids are compacted into a dry, stable cake that is easier, safer, and cheaper to transport or dispose.

Case Study: Refinery Saves Costs and Recovers Resources with OraDredge™ Mobile Units
The Challenge
A large refinery in India faced persistent sludge accumulation in its effluent treatment pits and oily lagoons. Each year, thousands of tons of sludge had to be collected and transported offsite. This caused:
-
High logistics and disposal costs.
-
Loss of valuable hydrocarbon-rich liquids trapped in sludge.
-
Compliance risks with wet sludge disposal.
-
Regular downtime during sludge collection.
The OraDredge™ Solution
The refinery partnered with ORAIPL to deploy OraDredge™ Submersible Robots for sludge removal and connected them to OraDredge™ Mobile Sludge Processing Units onsite.
The mobile units used Decanter Centrifuges and Screw Presses to dewater sludge and recover hydrocarbons, water, and solvents directly at the refinery premises.
The Results
Within just weeks of deployment, the refinery achieved:
-
70% reduction in sludge volume → drastically lower disposal and transport costs.
-
Recovery of valuable oil & water → turned waste into a revenue-saving stream.
-
Zero shutdowns → all cleaning and processing were done online.
-
Improved compliance & sustainability → safe, green disposal practices.
