Scraper Bridges

SOLIDS DRAG MECHANISMS  > Scraper Bridges

INTRODUCTION:

The scraper bridges for circular decanters manufactured by FILTRAMAS, S.A. have been designed to effectively extract the sludge and floats in primary or secondary decanters. The bridge is supported by a civil engineering column located in the centre of the tank and by the drive unit on the periphery of the tank. Its particular design allows a good adaptability of the equipment to the various irregularities of civil works.

DESCRIPTION:

Sweeping bridges mainly consist of the following elements

  • Drive group: Consisting on a fully enclosed carriage with driven wheel and drive wheel, in compliance with EC machine safety regulations, on which all the mechanisms are installed. The trolley is fixed to the mobile walkway by means of screws to minimize possible differences in the civil works.

  • Rotation table: This consists mainly of a large-diameter axial ball bearing capable of supporting high axial and tilting moment loads. Perpendicular to the bridge gangway, two oscillating ball bearing supports are provided to absorb any deficiencies in the peripheral running of the wheels.

  • Bridge Walkway: Constructed with UPN support beams, with latticework or with drawer-beam depending on the dimensions or according to the customer’s preferences. It is provided with protection railings built in tube of 1 ¼” ST-37 and access ladder, if the installation requires it. The surface of the platform is designed with a removable galvanised TRAMEX type flooring. All metal parts are treated with anti-corrosion treatment.

  • Surface/bottom sweeping scrapers: The structure of the sludge sweeping scrapers is fixed to the central turning gangway by means of tubular joints. The assembly system is simple and allows the scrapers to be adapted to any deviation in civil works. The support structure of the scrapers is made of tubular profiles. Standard production is hot-dip galvanized unless AISI-304, AISI-316 or other treatment is specified… The scrapers develop a profile that is close to that of a logarithmic spiral for tanks with a diameter of less than 20 m, so that the sludge is dragged in a complete rotation.

  • Feeding cylinder or central bell: Suspended from the bridge, it surrounds the central column of the civil works and is designed to stabilize the flow of the liquid inlet. It is built in two or more halves and is fixed to the walkway by supports.

  • Perimeter spillway and deflector: They are manufactured in stainless steel AISI-304, AISI-316 or aluminium, 3 mm thick. The spillway and spillway are fixed to the perimeter channel by means of special clamps fixed by means of anchor bolts, which makes it very easy to level them both.

OPCIONALS:

  • A set of rotating brushes can be supplied for cleaning channels and spillways driven by a gear motor.
  • We can build mobile suction bridges.

The accumulation of solid waste in water treatment requires effective mechanized solutions for its extraction. FILTRAMAS, S.A. has a wide variety of equipment for the dragging of solid waste.

Band screens are those equipments, installed in a channel or , which has a series of filtering surfaces in continuous movement. Its mission is to extract the suspended solids of a certain size that accompany the effluent. There are several types of band screens, depending on the characteristics of the effluent and the installation:

The objective of this equipment is to protect the WWTP or pumping well from the possible arrival of large objects capable of causing obstructions in the different units of the installation. This operation consists of passing the waste water through a screen that separates and evacuates the bulky materials dragged along. They will retain large-sized solids such as branches, leaves, paper, tree roots, plastics, wipes, rags, etc., preventing damage and blockages to pumps, valves, pipes and other elements present in subsequent treatment processes of the purification plant.

These devices allow to continue filtering while performing self-cleaning, being especially suitable for those applications where continuous filtering is an important parameter of the process. Filtramas recommends the installation of its FB or FW in-line filters according to the flow and filtration needs.

Filter sieves offer high performance in the solid-liquid separation process. Our range of equipment responds to the different possible needs for each case.

FILTRAMAS, S.A. has a wide range of solutions for the transport and compacting of the waste extracted by its machines, in a clean and discreet. The conveying and compacting systems can be with screws with final draining zone or hydraulic presses.

The conveyor-compactor screws supplied by FILTRAMAS, S.A., coupled together with its equipment, allow us to obtain a totally clean and fair-faced installation. The screw loading openings are designed for coupling to the discharge opening of the extraction equipment (bars movable grilles or screens), and the intermediate spaces are covered by a fairing.

In any water treatment or purification plant, there is a continuous need to isolate or regulate the flow of water in the channels and manholes or holes in walls (wall gates). This function is carried out by means of the placement of gates and cofferdams.

The result of our experience is the establishment of a standardization that determines a satisfactory result with a simple construction. For this reason, Filtramas has been developing the manufacture of penstocks and flashboards.

Filtramas manufactures channel hatches, wall hatches and cofferdams for different applications and uses.

The accumulation of solid waste in water treatment requires effective mechanized solutions for its extraction. FILTRAMAS, S.A. has a wide variety of equipment for the dragging of solid waste.

In the biological treatment of wastewater, a series of processes are generated based on the cultivation of bacterial microorganisms for the elimination of organic matter, nitrogen and phosphorus. It is one of the most common treatments for its simplicity and low cost.

FILTRAMAS, S.A. has a wide variety of equipment for bacterial culture applied to the treatment of urban and industrial wastewater.

The dewatering of sludge is an essential process in the management of solid waste generated in water treatment. FILTRAMAS, S.A. offers different mechanized solutions to the problem according to the different possible needs.

FILTRAMAS S.A. has a wide variety of solutions for all kinds of problems associated with the treatment and cleaning of water, mud and sand. We develop our specialisation on the basis of the experience accumulated by our professionals, constant effort and close collaboration with our clients. FILTRAMAS S.A. perfects new products, looking for economic and effective solutions. Any problem that arises in the handling of fluids is carefully analyzed in order to find an economically balanced solution.
