Technological Excellence

Filter On believes in providing indoor air filtration systems for every manufacturing industry and every commercial kitchen thats why Filter On uses three strong technologies for its Filteration systems namely-

  • Electrostatic Filtration Technology
  • Cartridge/Bag Type Filtration Technology
  • Wet Scrubber Filtration Technology

Electrostatic Filtration Technology :

Electrostatic Precipitator Technology

The Electrostatic Percipitator technology is effectively used to filter fumes, smoke, mist particles and dust particles. The technology is based on the principle of two-stage electrostatic air filtration. In this system, air is passed through an electrostatic field where fine suspended particles get charged. The charged particles get attracted towards opposite charged electrode plates and precipitate. As a result of this process, smoke-free, clean air is released back into the surroundings from the system exhaust. The filter elements are metallic and wahable. This makes it easy to maintain and eliminate recurring costs of filter replacement. The filters are capable of handling the smallest size of particles(0.01 micron to 10 micron). We offer various models of electrostatic precipitators depending upon the application, location, operational layout and performance requirements.

The Electrostatic Filtration System from Filter-On demonstrates high efficiency and an excellent return on your investment.

BENEFITS :

  • Zero Replacement Cost
  • Low Pressure Loss- Saves Running Cost
  • High Efficiency Even For Submicron Particles.

Cartridge/Bag Type Filtration Technology :

Media Type/Cartridge Type Technology

This is a simple system and can be easily deployed for separation of dry dust/ solid particles generated during various processes such as plasma cutting, laser cutting, grinding, polishing, welding, laser marking, graphite machining, woodworking etc. Dust-laden air is collected(sucked) and passed through a chamber where it passes through a cartridge filter. Fine dust particles get arrested on the surface of the filter and clean air passes through which is then released back into the enviouronment/ workplace. In this system, filter cleaning is automatically achieved through reverse pulsed jets of compressed air and the dust get accumulated in a bottom tray which can be easily removed and cleaned.

BENEFITS :

  • Routine maintenance is very easy as cleaning is automatic.
  • High efficiency
  • Works effectively for heavy dust loads

Wet Scrubber Technology :

Wet Scrubbing of Particulate Matter

Wet scrubbers can remove particulate matter by capturing them in liquid droplets. The droplets are then collected, with the liquid dissolving or absorbing the pollutant gases. Any droplets that are in the scrubber inlet gas must be separated from the outlet gas stream using a mist eliminator. Also, the resultant scrubbing liquid must be treated prior to any ultimate discharge or being reused in the plant.

A wet scrubber’s ability to collect particulate matter is often directly proportional to the power input into the scrubber. Additionally, a properly designed and operated mist eliminator is important to achieve high removal efficiencies.

If the gas stream contains both particulate matter and gases, wet scrubbers are generally the only single air pollution control device that can remove both pollutants.

How Wet Scrubbers Work

Water is the most common solvent used to remove inorganic contaminants. In the most basic form of wet scrubbers, water is encapsulated in a metal or composite container, contaminated gas is moved through the water, the water then absorbs the contaminates, and clean gas exits the scrubber.

Aside from water, other liquids can be used as absorbing solutions to effectively remove varied contaminates. Manipulating the chemical composition of the absorbing solutions changes the overall charge, which can be highly positively charged, negatively charged, or non-charged. Because pollutants differ in their charge, wet scrubbers are packed with the liquid that will bind most effectively to remove the contaminate from the gas. Caustic solution (sodium hydroxide, NaOH) is the most common scrubbing liquid used for acid-gas control (e.g., HCl, SO2, or both), though sodium carbonate (Na2CO3) and calcium hydroxide (slaked lime, Ca[OH]2) are also used.

Fume and Gas Wet Scrubbers

Fume and gas wet scrubbers are designed for most industrial air pollution applications, including scrubbing ammonia gas, chlorine gas, hydrochloric acid (HCL). They are especially effective on water-soluble fumes and odors.

Fume and gas wet scrubbers are manufactured with premium materials and quality thermoplastic construction for maximum corrosion resistance, plus UV-resistant PVC, polypropylene and polyethylene available for all outdoor installations.

Wet/Venturi Scrubber Technology

Venturi Scrubber Technology :

It is designed for capturing hazardous sub microns particles, welding fumes, odors and other water/chemically soluble fumes and vapor generated in industrial process. Venturi scrubber works on the principle of adsorption. A venturi scrubber is designed to effectively use the energy from the inlet gas stream to atomize the liquid being scrub the gas.

It consists of three sections: a converging section, a throat section, and a diverging section. The exhaust stream enters the converging section and as the area decreases, gas velocity increases. Liquid is introduced either at the throat or at the entrance to the converging section. The exhaust gas forced to move at extremely high velocities in the small throat section, shears the liquid from its walls, producing an enormous number of very tiny droplets. Particle and gas removal occur in the throat section as the exhaust stream mixes with the fog of tiny liquid droplets. The exhaust stream then exits through the diverging section, where it is forced to slow down. Venturi’s can be used to collect both particulate and gaseous pollutants, but they are more effective in removing particles than gaseous pollutants. Liquid can be injected at the converging section or at the throat. Thus, the liquid coats the venturi throat making it very effective for handling hot, dry exhaust gas that contains dust. Otherwise, the dust would have a tendency to cake on or abrade a dry throat.

Working principle

It works on the following principle where it creates a differential between higher velocity gas and highly energetic turbulence nature of the liquid creates droplets which helps in capturing the contaminants at a faster rate and making them as a highly concentrated slurry.

Features:

  • An easy-going design for the introduction of scrubbing liquid.
  • Fixed venturi throat dampers
  • Design do not involve mesh pads instead it contains cyclonic separator for mist elimination
  • In order to minimize the consumption of water it is designed with separate recirculation systems

Advantages :

  • Highly capable for removing pollutants like welding fumes
  • Initial investment cost is lesser
  • Design can be customized based on the application with less cost
  • Can reduce the high moisture streams
  • Ability to neutralize dust and gases which are corrosive in nature
  • Less maintenance
  • Operates with higher efficiencies
