TRAVELING SCREENS > Band Screens
INTRODUCTION:
The band Screen built by FILTRAMAS, S.A. are specifically designed for continuous operation in fresh water intakes of rivers, dams or sea. They are of robust and durable design and in the double flow model guarantee an optimal filtration without the possibility of larger size solids of larger size than the installed light passing through.
DESCRIPTION:
The band screen are installed in channels (single flow or direct flow model), or in pitchers (double flow model). The band screen is composed by the following elements:
STRUCTURE: The structure of the band screen is composed by two sets of guides for the panel support chains. Each set is made up of a lower curve and one or more intermediate sections, bracing the uphill and downhill rails of the same section together to keep the correct measurement and alignment between them.
FILTERING PANELS: The support frames of the filtering mesh are of mechanically welded construction, guaranteeing a distance between them never superior to the one allowed by the mesh size. A frame crossbar is designed and dimensioned to act as a bucket, thus allowing more effective removal of the brush to the collection channel provided on the working grounds.
PANEL CHAIN: The main chain carries the filter frames and is provided with steel bolts and bushings, with synthetic resin sliding rollers. The chain is tensioned from the upper head by a tensioning system and is equipped with special locks to ensure a proper seal between the moving parts and the static structure.
UPPER HEAD: The upper head connects the sliding guides of the main chain and supports the band grille drive assembly as well as the internal washing tube. The drive unit, consisting of a shaft, geared motor and drive gears, is installed on top of it.
COVER: For machine protection.
WASHING TUBE: The grille is equipped with a washing collector with spray nozzles.

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.
