    Sludge scraper

    Product Review:

    Portal type sludge scraper is widely used for removing sludge and floating contaminants from continuous flow-through tanks and sand catchers. It consists of a drive, overhead crane, lift unit, scraper system and electronic control system. Sediment and floating substance collection gutters can be installed at one end or both ends of the settling tank, as required.

    Operating principle of the portal sludge scraper is as follows:

    The unit starts running from the settling tank outlet end towards the inlet end, pushing the scraped sludge until the scraper reaches the opposite end.

    Then the unit reverses the travel direction and returns to its original position for a new cycle to start. The equipment is driven on steel rails by a drive unit, with the scraper pushing the sediment at the bottom of the settling tank into the sludge collection gutter.

    Application Sphere: Portable sludge scrapers are widely used in petrochemical, textile, food, paper, printing, brewing, pharmaceutical, leather industries, as well as in industrial and municipal wastewater treatment plants.

    Product Advantages

    Custom-designed scrapers eliminate dead zones in the settling tank. High manufacturing precision ensures the durability of the drive mechanisms. The company’s technological solutions are adapted to the climate of Uzbekistan, guaranteeing uninterrupted circulation of activated sludge.

    FAQ

    How does a sludge scraper help prevent activated sludge from floating in secondary clarifiers?

    When left on the bottom for long periods, activated sludge begins to rot and float due to gas release, which degrades the quality of the treated water. The ASMEX PETROCHEM sludge scraper ensures continuous movement of sludge toward the central sump for rapid pumping. This maintains the freshness of the sludge mixture and the stability of biological treatment.

    What materials are used for bottom scrapers to prevent wear on the concrete bottom?

    The scraper's working edge is made of wear-resistant rubber or special polymers. This allows it to adhere tightly to the bottom surface for complete sludge collection without damaging the concrete base of the clarifier. This design minimizes the cost of tank bowl restoration during long-term operation.

    Is special site preparation required for sludge scraper installation?

    The equipment is mounted on standard radial settling tanks. Before installation, our engineers check the geometry of the bottom and sides. Precise adjustment of the support rollers and guides compensates for minor imperfections in the concrete structure, ensuring smooth operation without jerking or jamming.
