Self Cleaning Filter

Buying A Self Cleaning Filter Is The Right Choice To Reduce Your Effort

The filters that clean themselves automatically are the optimal choice for most municipal, industrial and irrigation applications. Self cleaning filters utilize system pressure to clean themselves. They are easy to maintain, have a short cleaning cycle and waste minimal amounts of liquid. They are also easy to install in existing or new systems. In addition, they do not interrupt the main flow during the backwash cycle.


Self cleaning filters can be used in a variety of applications where the continuous flow of water is critical. They can be used in municipal water treatment, irrigation nozzle protection and industrial equipment protection. The following are the reasons why you should consider buying a self cleaning filter.


Easy to maintain


Self cleaning filters have a self cleaning mechanism that makes it unnecessary to carry out routine maintenance because it automates the cleaning cycle. The controller monitors differential pressure and automatically initiates the backwash cycle. Therefore, this cleaning technology saves operating costs and maintenance time. When using a self cleaning filter, it is not necessary to perform spray downs, manual washes, and bag, filter and cartridge replacements. Basic annual or biannual inspections replace the need for monthly, weekly or daily shutdowns, depending on particle load.


Continuous operation


Debris accumulates inside the stainless steel screen of the filter. When the automatic cleaning cycle is initiated by differential pressure, flow reversal takes place at the suction point instead of throughout the filter. This allows for continuous flow in the whole filter for the duration of every backwash cycle. In order to maintain system continuity during the annual or biannual maintenance, you may install multiple self cleaning filters in parallel. This configuration offers a larger cumulative screen area, allowing for one or several filters to be removed for periodic maintenance without having to interrupt the filtration process.


Brief cleaning cycle


Self cleaning filters usually require only four to twenty seconds to complete a backwash cycle. When cleaning other kinds of filters such as cartridge and bag filters, it may take a few hours to complete the cleaning cycle.


Easy installation


The manufacturers of self cleaning filters offer filters in many orientations, sizes and various degrees of filtration in order to meet the demands of different clients. The filters are easy to install. They have a straight flange configuration and can integrate with all kinds of straight pipelines.


System control


Self cleaning filters have a control system. It is designed to be easy to operate, reliable and able to initiate a flush cycle either on a timed basis or by high differential pressure. Good control systems have an alarm function that warns operators if the filter is not functioning properly. LCD displays also show the how many times the filter has been backwashed. Controllers are designed to fit the application and they range from small battery powered controllers to large industrial controllers. Industrial controllers can flush up to 10 self cleaning filters in parallel. Small battery powered controllers are ideal for controlling the filters situated in areas where there is no source of power. The battery can last for one year.


When choosing a filter, it is important to assess some variables. These variables include the available equipment, the reliability required by the system, installation costs and maintenance costs. You should also consider the necessary degree of filtration and wastewater replacement. Considering these factors will help you select the right self cleaning filter for your needs.
