Perforated sheets - Import export

The best solution for tertiary filtration: high solid removal yields, minimum water and energy consumption. In the TF – TV VM (VM = metal tank) series the cloth support is made of a perforated metal sheet drum. This model is used for wastewater treatment plants of small working capacity (up to 2.000 PE) or as a secondary treatment downstream from immobilized biomass systems. It is available for installation in concrete tanks or metal tanks versions. The equipment is supplied with an electrical switchboard. - Gravity filtration with limited head loss. - Continuous filtration without standby units for the backwash phases. - Cloth filter in polstoff free fibre provided with high mechanical strength. - High filtration rate (concentrations of TSS < 5 mg/l at discharge).

The paper hand towels are available in different versions. Center feed rolls, perfect to be inserted in the special dispensers, kitchen towels or traditional rolls with perforated sheets. The two-ply cellulose of the center feed rolls is microembossed, it's soft and fluffy, perfect for drying your hands. The paper of the wiping rolls can be either embossed or smooth, in both cases, they are also available with the recycled paper. This wide range is designed to meet all needs, not only to dry hands, but for all uses as well.

The noise reducer is a barrier devices that enhances the performances by virtue of sound wave propagation at the point of "diffraction". With the installation of the noise reducer it is possible, the acoustic result being equal, to reduce the barrier height thus obtaining a benefit in terms of visual impact. The elliptical noise reducer, thanks to its special geometrical configuration, can be installed on any type of barrier, reducing the sound pressure field behind the screen. The installation of the elliptical noise reducer guarantees an increase in the Insertion Loss value ranging between 1.7 and 4.4 dB(A) depending on the chosen reception in the barrier acoustic shadow area, and the testing method, the height being equal or adding the reducer, as certified by free field testing, in compliance with standard ISO 10847. The elliptical noise reducer consists of a shell of aluminium sheet, or hot-galvanized painted perforated sheet with circular holes with six different diameters, to o
