cofferdams

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:

• Band Screens
• SCM Channel SCREEN
• Micro- Screen

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.

• Model ER
• Model PR
• Model RC/FC

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.

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.
