Introduction

General Description

• The FILTOMAT MG110 is a sophisticated, yet easy-to-operate automatic filter, with a self-cleaning mechanism driven by a hydraulic turbine. It is designed to work with various types of screens in filtration degrees from 500 to 80 microns, and is available in 10″
  inlet/outlet diameter.
• The FILTOMAT MG110 filter is configured to meet your specific needs according to flow rates and water quality. The filter can be installed as a stand-alone unit for low flow rates or assembled in a group on a manifold when high flow rates and/or a large screen area are required. The filters are delivered fully assembled, requiring simple connections to the inlet and outlet, and the drain.

Basic Filter Operation
Water enters the filter from the inlet pipe, and passes through a coarse screen, which protects the automatic cleaning mechanism from any large particles or debris. The coarse screen is not cleaned automatically and should not accumulate large quantities of solids. The water then flows through a fine screen which filters out the smaller particles. Water that has passed through the fine screen is clean and passes into the outlet pipe. Particles of dirt accumulate on the fine screen and form a “filtration cake,” which starts to restrict water flow. As the restriction, or clogging, increases, the pressure in the outlet pipe becomes lower than in the inlet pipe. When the pressure differential reaches a pre-set value, a self-cleaning cycle is initiated. The self-cleaning cycle takes approximately 45 seconds and does not interrupt the flow of water through the filter.

Self-Cleaning Cycle

• At a preset pressure differential (0.5 bar —7 psi), which is detected by a pressure differential switch, the flushing controller operates pulse solenoids which allow water to flow to the relay valves, which then activate the hydraulic pistons and open a valve to the rotor chamber (See Figures 2 below). The water from the rotor chamber flows out the drain. The pressure in the rotor chamber drops, releasing a strong flushing stream that flows through the filter.
• This pressure drop and the corresponding release of the backflush stream creates a suction effect at the nozzle inlets. This effect actuates spot cleaning directly in front of the openings of each nozzle at the inner side of the fine screen. The water and particles passing through the hydraulic rotor cause the suction scanner to rotate, and the piston moves in an axial direction to the opposite end of the filter.
• The combination of rotational and axial movement of the suction scanner assembly ensures that the nozzles sweep the entire inner side of the fine screen in a spiral pattern.
• When the first stroke is completed, the flushing valve closes and after a short interval, the flushing controller activates the second backflush stroke. The suction scanner assembly spins, moving with the piston in the opposite direction and returning to its original position.
• This self-cleaning process takes about 45 seconds, depending on the operating pressure.
• There must be at least 2 bar pressure at the inlet to the filter for proper cleaning to take place during flushing.
• The flushing controller may be operated by pressure differential, manual activation, or by timer.

Installation

Design Recommendations

• The inlet and outlet pipes must be the same or have a larger diameter than the inlet and outlet diameters of the filter.
• The upstream pressure source should not drop below 30 psi (2 bar) during the rinse cycle. If this cannot be ensured, consult the manufacturer.
• If a prolonged pipeline fill time causes a temporary high flow and low-pressure situation, it is recommended that you install a pressure-sustaining valve downstream of the filter. The pressure-sustaining valve will ensure a controlled fill-up of the line.
• If continued water delivery is essential even during “downtime” maintenance periods, it is recommended that a manual or automatic bypass be installed and that isolating valves be installed up and downstream of each filter unit for isolation purposes.
• Shut-off valves must be installed in the inlet and outlet lines to enable maintenance.
• A non-return valve should be installed where water hammer or backflow may be a problem.
• The filter must be installed in the direction of flow indicated by the arrow on the filter body.
• Secure the drain pipe so that there is no movement during flushing.
• The highest point of the drain pipe should be no more than one-half meter above the filter.
• The drain pipe must allow free flow and be free of restrictions.

Preparations for Installation 

• Ensure suitable lighting at the area of the filter to enable good visibility and safe maintenance.
• Arrange suitable platforms and safety barriers to enable easy, safe access to the filter.
• Allow a convenient approach and enough space for dismantling and maintenance.

Installation Instructions 

• Ensure the direction of flow is according to the arrows marked on the filter housing
• Install a drain valve in place of one of the pipe plugs in the inlet or outlet pipe on the installation manifold.

Important! 

• Prevent static back pressure or reverse flow through the filter.
• Install a manual or a hydraulic valve downstream of the filter.
• The filter may enter flushing mode automatically, without warning.

First-time Operation

1. Remove a plastic plug from one of the outlet holes on the top of the filter to bleed air from the filter.
2. Open the inlet valve.
3. Close the plastic plug when all the air is bled from the filter.
4. Make sure the filter is clean and dry.
5. Check all fittings and flanges for leaks.
6. Open the outlet valve.
7. Perform manual flushing, by selecting “Manual” in the flushing controller.
8. Check that the inlet pressure does not drop below 2 bar during flushing.

The filter is ready for operation. Observe at least one automatic flushing cycle, activated by time or differential pressure.
