The term fine particles, or particulate matter PM 2.5 refers to tiny particles or droplets in the air that are two and one half microns or less in width. Like inches, meters and miles, a micron is a unit of measurement for distance. There are about 25,000 microns in an inch. The widths of the larger particles in the PM 2.5 size range would be about thirty times smaller than that of a human hair. The smaller PM 2.5 particles are so small that several thousand of them could fit on the period at the end of this sentence. All fine particles that are two an a half micrometers in diameter or smaller are also referred to as PM 2.5.

Field assembly of electrical and opacity control systems is costly and inefficient. PPC completes as much opacity control assembly, mounting, conduit, wire and programming as possible at our facility before it gets to your property to decrease field installation cost. Electrical one line, conduit and connection table, interconnection diagrams and panel layout drawings are provided to the customer for system integration. Each panel is constructed using only name brand quality components and are factory tested before shipment. PPC can insure complete compatibility with all existing plant distributed systems. Opacity control systems are designed to accommodate the customer’s budget and specific objectives. With the basic having panel push buttons, opacity control systems are available with computer data logging as well.

The dry electrostatic precipitator is employed on hot process exhausts (250 - 850 deg. F) that operate above the dew point of the gas stream. The dry electrostatic precipitator typically handles collection of dust particles such as wood ash, incinerator ash, or coal ash from boiler or incinerator applications. Additional air pollution control applications include carbon anode ovens, cement kilns, and petroleum cat crackers. Our dry electrostatic precipitator systems are attractive due to their ability to collect and transport the dust in a non wet condition. This eliminates the use of water and the concerns of pollution, corrosion and dewatering efforts associated with scrubbers. For more information on our dry electrostatic precipitator, call (903) 758-3395 today.

The wet electrostatic precipitator is employed on gas streams that include oily and sticky particulates or gas streams that must be cooled to saturation in order to condense aerosols that were formerly in the gas air phase. The wet electrostatic precipitator uses water flushing systems to remove the particles from the collecting surface. The stream is either saturated before entering the collection area or the collecting surface is continually wetted to prevent agglomerations. The wet electrostatic precipitator is an effective pollution control on acid mist, oil and tar based condensed aerosols or applications where dry dust particles combine with condensables to form paste residues.

Although not designed as a particulate control device, the biofilter will act as an effective filter. Knowledge of the characteristics of the off gas considered for biofilter treatment is essential in achieving particulate control and avoiding performance problems. Occasionally, the full-scale biofilter size has been based on available off-gas technical monitoring results without conducting a test. This approach requires an understanding of the assumed composition and accuracy of the theoretical models applied. Experience with industrial particulate control has shown that comprehensive understanding of an off gas stream with respect to pollutants and temperature is often lacking. Call us today at (903) 758-3395 to see how our knowledge of particulate control can help your business.

A PPC Biofilter provides a pretreatment system to condition the gas stream for optimum biological parameters. This includes temperature conditioning, humidification and particulate removal. The gas stream then flows into a fixed media reactor in the Biofilter where the phase transfer and biological oxidation takes place. A Biofilter breaks down organic compounds using bacteria at ambient temperatures. This method is termed Biological Oxidation. Volatile Organic Compounds (VOC's) and Hazardous Air Pollutants (HAP's) such as Alcohol's, Ketones, Light and Heavy Hydrocarbons are destroyed through a process called Oxidation. There are many advantages to this system, including costing you less per ton of VOC’s removed than any other method, call us today at (903) 758-3395 to find out how a Biofilter can help your company.

An electrostatic precipitator is a device that captures particulates from a gas stream. Maximum effectiveness of the system occurs when the voltage supply output reaches the sparking threshold. Variation in gas volume, dust loading and other factors, however affect the sparking threshold level of the electrostatic precipitator. Employing an advanced electrical control system, an automatic control circuit regulates each high voltage power supply output for maximum electrostatic precipitator efficiency regardless of process variation. Sparking causes the power supply to notch down slightly with the automatic controls bringing it right back up to sparking potential. Modern digital electronic controls automate this process and assure operation is at its peak performance levels at all times on the electrostatic precipitator.

A dry ESP is employed on hot process exhausts (250 - 850 deg. F) that operate above the dew point of the gas stream. This dry ESP will typically collect dry dust particles such as wood, incinerator, or coal ash from boiler or incinerator applications. Additional applications include carbon anode ovens, cement kilns, and petroleum cat crackers. Dry ESP units are attractive due to their ability to collect and transport the dust in a dry condition. This eliminates the use of water and the concerns of pollution, corrosion and dewatering efforts associated with scrubbers. If the dust particles can be collected and handled in a dry condition it is always more advantageous to employ a dry ESP.
