Palin Sludge Consolidator

ALSI Palin Sludge Consolidation System

Also known in the industry as a Vertical DAF (Vertical Dissolved Air Flotation) system, the ALSI Palin Sludge Consolidator is an automated and continuous industrial sludge collection, consolidation, and removal system used in industrial processing plants that produce wastewater containing various contaminants like paints, oils, greases, and proteins/fats.

Specifically engineered for challenging industrial sludges, this vertical DAF-style solution reduces disposal and operational costs by removing water from sludge and returning clean water back to the process. Simple by design, the Palin provides a reliable, process liquid clean-up for floating suspended solid separation applications.

ALSI Palin Sludge Consolidator Benefits:

  • Reduces cost of chemistry programs
  • Minimize down time due to system interruptions
  • Minimal utility consumption
  • Smaller footprint compared to competing technologies , including traditional horizontal DAF units
  • Increased efficiency compared to standard centrifuge equipment
  • Higher rates of water reuse

The Palin—recognized by some in the wastewater industry as a vertical DAF system—is one piece of the total sludge solution offered by Air Liquid Systems (ALSI). It works best when paired with the Checkmark Sludge Dryer to round out the complete sludge processing workflow.

How Does a Palin Consolidator Work?

Sludge-laden water collected from a recirculation tank is continuously sent to the Palin Sludge Consolidator, which performs the core function of a vertical DAF system—consolidating and removing floating industrial sludge.

The Palin system utilizes a MASCon (micro-aeration system) to introduce fine air bubbles that enhance solids flotation—similar to the dissolved air flotation principle. These bubbles attach to rising paint particles, aiding in their separation and removal. As these particles coagulate into a sludge mat, they are scraped from the surface and directed into a dewatering system like a bag or sludge dryer.

Why Choose a Palin (Vertical DAF System) for Sludge Removal?

Whether you refer to it as a Palin or a Vertical DAF system, this solution offers one of the most efficient and cost-effective methods for industrial sludge consolidation and water reuse. Its compact vertical design allows for smaller installation footprints compared to traditional DAFs, making it ideal for facilities with space limitations.

Compared to traditional centrifuge or horizontal DAF systems, the Palin’s vertical orientation and micro-aeration approach lead to enhanced sludge removal with minimal water loss. This positions it as a standout option for companies seeking a modern vertical dissolved air flotation solution.

Frequently Asked Questions (FAQ's)

Answer:

The Palin Sludge Consolidator offers numerous advantages over competing centrifuge technologies. A few key differences in design and performance are listed below:

  • Palin: Zero maintenance or downtime required.
  • Centrifuge: System bearings need to be rebuilt frequently and a rotating assembly maintenance.
  • Palin: Custom controls can communicate with a wide variety of plant PLCs (Programmable Logic Controllers).
  • Centrifuge: Standardized equipment where one size tries to fit all applications
  • Palin: Less than 50 PPM of solids returned to the process.
  • Centrifuge: Returns several thousand (2,000 – 10,000 PPM) solids back to the process water.
  • Palin: Can handle significantly larger volumes at a higher rate.
  • Centrifuge: Limited effectiveness when handling large volumes.
  • Palin: Adds retention time to the system, creating a larger hydraulic footprint, facilitating easier management of de-tack chemicals.
  • Centrifuge: Does not contribute to retention time or hydraulic footprint in the same way.
  • Palin: Designed specifically for each individual system, considering both hydraulic and solid loading characteristics.
  • Centrifuge: Standardized equipment where one size tries to fit all applications
