VP Series Carbon Filter
GENERAL SYSTEM DESCRIPTION
General Description
The carbon filter designed and manufactured for industrial applications. They are rugged, preengineered, pre-assembled catalog units that minimize expensive installation and start-up costs.
They require simple utility connections and media loading for immediate online service. Their
simple design maximizes the efficiency and repeatability of the unit during the service and
regeneration modes in order to provide a truly reliable water treatment unit.
Mechanical Description
The carbon filters consist of steel pressure vessel that contains granular activated carbon media. The
pressure vessels are sandblasted, lined and painted with a durable epoxy material. The piping is
constructed of Schedule 80 PVC or Schedule 40 galvanized steel. Complete piping from the inlet to
the outlet of the filter vessel is provided. All automatic valves are hydraulically actuated using
feedwater pressure. Four structural steel legs designed for seismic zone 4 support each vessel.
Duplex units are supplied with a structural steel beam frame under the vessel legs and manual
isolation valves for the feedwater and product water.
Electrical Description
A highly reliable solid-state controller is used to control the operational sequences and monitor
the performance of the carbon filter. Opening and closing of the process valves is accomplished
using feedwater as the motive fluid and a stager pilot valve located in the control enclosure. All
electrical components are contained within a NEMA 4X FRP enclosure. The day and time of
backwash are easily set.
Operational Description
The carbon filter has two modes of operation, Service and Backwash. When the day and time of
the pre-set backwash is reached, the filter controller will automatically begin the backwash
sequence. Afterwards, the filter will return to the Service mode. The backwash mode has two
steps, Backwash and Rinse. Step times for the Backwash and Rinse are easily adjustable on the
controller.
Duplex systems will operate in parallel fashion. In the parallel fashion, both filters will be in the
Service mode. At the pre-determined time or event, each filter will backwash independently,
maintaining at least one filter in the Service mode providing a continuous, uninterrupted supply
of filtered water.
