Advanced Pre-Treatment Equipment for Settlable and Floatable Contaminants
The WAU-S / WAU-SW represents high-performance equipment specifically engineered for the efficient removal of both settleable solids and floatable contaminants from diverse organic streams. It ensures optimal protection for downstream processes in critical applications across biogas plants, agricultural operations, and various industries.
The WAU-S / WAU-SW represents a state-of-the-art solution developed for the precise separation of various abrasive inorganic particles and troublesome floating materials from organic matrices. Designed to safeguard delicate downstream equipment like digesters, pumps, and heat exchangers, this unit significantly reduces wear, maintenance costs, and system downtime caused by the accumulation of unwanted contaminants. Its primary function is to deliver purified organic streams, optimizing subsequent treatment phases.
At the core of the WAU-S’s exceptional performance is an innovative multi-stage mechanism. Incoming flows are introduced into a specialized tank where a combined effect of micro and macro air bubbles creates a unique deposition phenomenon for settleable particles, such as grit and sand. These heavier inorganic components settle efficiently to the bottom. A lower horizontal conveyor auger then precisely conveys the deposited materials to an extraction area. Here, an inclined screw extracts and discharges the dewatered grit, achieving a remarkable density of up to 20% for the removed material. The WAU-S boasts an impressive separation efficiency of up to 97% for particles with a size equal to or greater than 200 microns.
For enhanced functionality, the WAU-SW variant incorporates additional scraping paddles. These paddles actively scrape the liquid surface within the tank, effectively removing floatable contaminants and suspended elements, further purifying the organic stream.
The WAU-S / WAU-SW is engineered for unwavering reliability and minimal maintenance. Constructed predominantly from high-quality AISI 304L/316L stainless steel, this equipment offers superior corrosion resistance and durability in demanding environments. Key components like the spiral, bottom, carpentry, and supports are available in various robust materials, including SS304, SS316, Duplex, Superduplex, ensuring a tailored fit for specific operational needs and extended service life. Its design prioritizes continuous operation with low energy consumption and a remarkably low noise level.
Thanks to its specialized design for robust removal of both settleable and floatable contaminants from organic streams, the WAU-S / WAU-SW finds critical application in energy production, particularly within biogas plants.
Here, it plays a vital role in purifying incoming organic feedstocks, such as food waste and manure, by effectively preventing grit accumulation in digesters and removing floating impurities.
This crucial pre-treatment maximizes biogas yield and significantly protects expensive downstream equipment.
The unit is also indispensable in general food waste processing and manure management, ensuring cleaner organic inputs before further processing or anaerobic digestion.
Furthermore, it serves as a vital initial stage for various industrial and municipal wastewater pre-treatment plants, safeguarding subsequent processes from a wide range of contaminants. Its high reliability, low energy consumption, and minimal noise ensure seamless operation.
Coupled with simple maintenance requirements and superior contaminant removal, it provides robust protection for all downstream equipment, ultimately leading to efficient and sustainable organic material pre-treatment and substantial operational savings.
The WAU-S / WAU-SW is available in models treating flow rates from 10 to 100 m³/h, with optional devices like air blowers, level sensors, and agitators to meet specific operational requirements. It stands as an indispensable tool for efficient and sustainable organic material pre-treatment.
