REMOVAL SOLIDS
Cartridgefilters

Multivis supplies 2 models ,
1. at work under low pressure - 0.3 bar from 200 micron
2. at work under high pressure - 2.5 bar from 30 micron

1. LOW PRESSURE CARTRIDGEFILTERS
Advantages: self-cleaning high flows possible: max. 500 m3/h less pre-pressure necessary to let the filter work: 0.2 - 4 meter less pressure necessary to wash: 3m suitable for seawater simple in design suitable for continuous use almost no servicing

CLEANINGCYCLE:

Normal at work: The wash valve is closed and the plunger, which is assembled in the upper cover, is over the filter basket.	Cleaning - first stage: The cleaning cycle is started when by accumulation of dirt pressure difference occurs, or after an adjusted time interval. The wash valve is opened and a lot of dirt is pushed out.	Cleaning - second stage: The  plunger is making two complete strokes in the filterbasket. The velocity of the liquid between the filterbasket and the plunger is increased, due to this a pressure-loss is created. As a result the stream direction is locally turned, and particles sticking to the filterbasket are removed.

2. HIGH PRESSURE CARTRIDGE FILTERS

Advantages: complete automatically rewind process which is started by a previous adjusted pressure difference rewinding with the liquid available and process pressure low pressure-fall over the filter is saving energy costs rewinding by little nozzles through which a local cleaning effect is reached so that a high rewind speed comes to existence and a cleaning of 100% is reached continuous circulation even during the washing process  high capacity and compact units filter fineness afterwards easy to adapt to the process circumstances strong and simple design
