  • Pilot Testing Microfilters and Cloth-Media Filters for Lake Augmentation

    ABSTRACTMicrofiltration and cloth-media filtration were pilot tested for plant expansion and water supply augmentation purposes. The performance of the pilot units was assessed by evaluating key influent and effluent data, including suspended solids, turbidity, total phosphorous, hydraulic loading rate, flux, and chemical addition. Results showed that one of the cloth-media filters, and both of ...

  • New Cloth Media Filter System Replace 4 MGD Traveling Bridge Filters with 12 MGD Capacity in Existing Tankage

    ABSTRACTThe Little Falls Run Wastewater Treatment Facility began experiencing operational difficulties with the dual-bay traveling bridge filter process as flows approached the rated capacity for the filters. Although initially the Utilities Department staff intended to duplicate the original filter process and thereby double the capacity, the recent introduction of a cloth media filter product ...

  • Fox Metro Water Reclamation District Solves Filtration Problems with Innovative Aquadiamond® Cloth Media Filter

    The Fox Metro Water Reclamation District evaluated, installed, and successfully tested cloth media filtration in a diamond configuration in existing traveling bridge sand filter tanks. The conversion to the cloth media diamond filters increased the flow capacity of three existing sand filters basins from 79,485 m3/day (21 MGD) to 272,520 m3/day (72 MGD). The diamond filter builds on cloth media ...

  • Cloth Media Filtration Technology Meets Very Low Total Phosphorus Levels in Existing WWTPS.

    ABSTRACT Alexandria (Minnesota) WWTP and Cayuga Heights (New York) WWTP are both facing new discharge permits that include more stringent total phosphorus (TP) levels of 0.3 mg/L and 0.2 mg/L, respectively. An AquaDisk® cloth media filter pilot unit was brought to these sites for a period of three (3) weeks each. Results of the two (2) pilot studies demonstrate that the cloth media ...

  • To prevent blinding in dust collection systems, consider filter type, filter size and selection of the filter media used

    All dust collection systems, regardless of size, share a common problem—dust blinding. Simply stated, blinding is defined as when dust particles plug the holes in a filter and stop the flow of air through the filter, resulting in the dust collector performing poorly. All types of collectors, whether stand-alone units, cyclones or full-scale baghouses, are subject to blinding. To better ...

  • Combination filters

    Simply defined, a combination filter is one that does at least one other processing job at the same time as filtering a suspension. The classic example, of course, is the packed bed of activated charcoal, which acts as a remover of chemical impurities from the suspension, as well as removing dust particles - although this is actually not a very good example, because it is primarily an adsorber, ...

  • Solid / gas separation with fabric filters

    A myriad of filter media are utilized today for separation of particulate matter in industrial gas filtration applications. These media range from single use (deposable) to semi-permanent media and include fiber, fabric, ceramic, membrane, metal mesh, and sintered metal media. Semi-permanent media are usually cleanable, either on or off-line, and are primarily intended for long-term (up to ...

  • Improve performance by installing a larger filter bag

    YOU MIGHT NOT NEED a more powerful dust collector after all. That’s the word from woodworkers who’ve replaced the original equipment filterbags on their collectors with bags that are more efficient. You might ask, “What can be more efficient than the 1 micron bag that came with my collector?” The answer is a 1 micron bag that’s properly sized for your machine and ...

  • Side-by-Side Pilot Testing of Two Disk Filter Manufacturers at the City of Merced Wastewater Treatment Plant

    ABSTRACTAs more wastewater treatment facilities upgrade to tertiary treatment for pathogen removal and trace pollutant reduction, the options for tertiary filtration expand. The use of cloth-disk media filtration (disk filters) for tertiary filtration is becoming more common because of the effluent quality, lower backwash rates, small footprint, and ability to meet ...

  • Ineffective cleaning in generic baghouses

    ABSTRACT: Background In a typical “generic” baghouse application, the cleaning is accomplished by back-flushing the filter with compressed air that travels through an orifice hole in a purge tube (blow pipe) and through a venturi. A typical generic cleaning system allows dust to be filtered at an air-to-cloth ratio of 5:1. That means for every 5 CFM of airflow, there is 1 square foot ...

  • Efficient Removal of Organic and Inorganic Suspended Solids

    ABSTRACT The Romans used sand as a filter media to treat their drinking water 2000 years ago. Centuries ago water was poured through layers of cloth to remove visible impurities in drinking water with fabric bags and paper cartridges soon following. Darcy employed sand beds in Dijon, France over 200 years ago to conduct his experiments for developing his famous equation to describe fluid flow ...

  • New Nozzle Technology “Cleaning More with Less”

    This technical paper will explain the new nozzle technology developed by Scientific Dust Collectors that allows high air-to-cloth ratio baghouses to use 80psig of compressed air instead of the industry standard 100psig.   The reverse pulse jet baghouse has been around for over 50 years and the cleaning cycle has not changed very much during that time. The cleaning cycle is the most important ...

  • Compacting waste - Case Study

    Throw away little things and save big bucks? It hardly seems likely, but that's just what the U.S. Air Force is doing. At Randolph AFB, TX, they are putting usedand hazardous-air filters into a state-of-the-art industrial compaction machine and saving thousands of dollars in hazardous waste disposal. The air filters contain aircraft paint removed by plastic media blasting (PMB). Small plastic ...

  • Inetgrated Planning for Wastewater Treatment and Recycling for a Small Community Development

    ABSTRACTIntegrated water resources planning was conducted for Olowalu Town, a proposed development in western Maui, Hawaii. Total water needs, which can be supplied by a combination of diverted surface water, well water, recycled water and captured stormwater, are estimated at between 1 and 2 mgd. The Olowalu development will generate approximately 0.5 million gallons per day (mgd) of municipal ...

  • ENI - 100 m3/h produced water treatment
