Features and structure
The QUILTON static screen basically consists of a chassis and a filtering grille. Its originality lies in the shape of the bars on the grille, which give it major advantages over static screens with straight bars.
In addition, the QUILTON static screen has three sloping sections. Two for filtering and the last one for draining. The first provides the main filtering of raw waters, followed by filtering on the second ramp, while the third performs the final draining of the solids retained by the static screen. The following are the advantages provided by the three different ramps:
- Filtering the highest volume of water.
- Retaining any solids larger than its spacing.
- Draining the solids prior to discharge.
- Chassis: this component is made of stainless steel. It also doubles up as a tank, which is divided into two parts:
- The first, the upper part, is in the inlet for the liquid to be screened, where it overflows and passes into the filtering grille.
- The second, the lower part, receives the filtered liquid, where gravity draws it out through the outlet flange.
- Filtering grille: it consists of triangular corrugated laminar grilles, forming a sinusoidal grille. This filtering grille consists of three ramps, with each one sloping at a different angle.
- Covers: besides providing safety and protection, the covers on the QUILTON Static screen minimise any possible odours coming from the liquids to be screened.
- System for turning the filtering screen: the filtering grille has a shaft that enables it to turn. The turning action involves releasing the upper clips and the bolts on the discharge ramp. This allows cleaning the inner face on the filtering grille, as well accessing the lower tank for maintenance purposes.
