Pile Cloth Media Filters - Disc series (PEC – PEC VM)

The best solution for tertiary filtration: high solid removal yields, minimum water and energy consumption. The tertiary filtration is strongly influenced by the hydraulic profile of the plant, which often cannot be changed. In the PECV VM (VM = metal tank) disc filters series the collection shaft is placed vertically. The goal is to feed equipment completely submerged even with very low hydraulic profiles. Even for this series, cloth washing is done with pumps, each of which is served by two or more discs. The pumps are actuated in sequence in order not to disrupt the functionality of the system. The PECV VM solution is ideal for small-medium unattended systems with heavy and extremely variable loads. The largest model of this series can process a load equal to a community of approximately 10.000 PE. The various models can be installed in parallel to obtain various working capacities. - Gravity filtration with limited head loss.

The best solution for tertiary filtration: high solid removal yields, minimum water and energy consumption. The PPC – PPC VM (VM = metal tank) series was developed for plants with medium-large potential. For filters in this range, cloth washing is done with two pumps only (of which one backup pump) which serveall the discs. The selection of discs on which to conduct the backwash (in sequence) is carried out by using double-acting valves with pneumatic control. The largest standard model in this series has a filtering surface of 160 m2 that can process a load equal to a community of approximately 50.000 PE. A singular feature of this series is the low energy consumption, even more noticeable with the increasing plant potential. - 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.

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 standard model is made with wetted parts manufactured in AISI 304, the support legs in treated and painted carbon steel, filter element of quartz sand of suitable grain size. Special executions and alternative materials are available on request. Typical applications: tertiary treatment of civil and industrial waste water, surface water clarification, treatment of drinking water, primary filtration of civil and industrial waste water, clarification of metallurgical industry cooling water, algae removal, pre-treatment for ultra-filtration membrane installations, pre-treatment for ozonisation plants, finishing treatment with active carbon. - Low first costs and plant management costs - High efficiency and reliability for the removal of suspended solids, even colloidal - Exclusive backwash system which uses raw water rather then filtered water - External sand recirculation system - Ease of installation Possibility of gravity feed, thanks to its low pressure drops
