Heavy Duty HEPA Vac

EXAIR’s new Heavy Duty HEPA Vac attaches to an ordinary 55 gallon open top drum to turn it into a powerful, HEPA quality, industrial vacuum cleaner. The Heavy Duty HEPA Vac is designed to move more material with less wear. In addition, this vacuum has been engineered to filter contaminants to HEPA requirements in dusty environments requiring frequent cleaning. It is extremely quiet at 82 dBA (half the noise of electric vacs), making it suitable for a wide variety of environments. An economical, easily maintained pre-filter stops larger particles, while the HEPA filter handles the smaller matter. All filters are tested for minimum 99.97% filtration at the 0.3 micron level to meet HEPA standards in strict accordance to IEST-RP-CC-007. The Heavy Duty HEPA Vac System comes complete with the Heavy Duty Dry Vac, lever lock drum lid, shutoff valve, pre-filter, HEPA filter, 10' (3m) static resistant hose, hose hanger, 1/2 NPT quick connects coupling, 20' (6m) compressed air hose, pressure gauge, and aluminum chip wand (drum not included).

    Reduces energy consumption and increases MBR technology

    LEAPprimary

    LEAPprimary significantly reduces overall energy use, costs and physical space requirements by combining separation, thickening and dewatering of primary wastewater solids into one compact, high-performance unit. It replaces conventional clarification and fine screening in a typical MBR plant. LEAPprimary offers high removal of total suspended solids (50-70 percent) and biochemical oxygen demand (25-40 percent), and the removed solids can be dewatered to 20-30 percent dry matter, minimizing handling costs. Since solids and organic material are removed prior to secondary biological treatment, energy use for biological treatment is reduced.

      www RESOURCE DAF

      World Water Works, Inc. announces the availability of its new www/RESOURCE DAF, a next generation dissolved air flotation (DAF) system that handles flows from 5,000 to 8,000 gallons per minute (gpm) and is ideal for industries ranging from food processing, to desalination pretreatment, to textiles, to petroleum, and beyond. Pilot treatment plants are available and thorough bench testing and pilot treatability studies are conducted to guarantee results.

      With a high total dissolved solids (TDS) and saltwater tolerance, www/RESOURCE DAF provides the flexibility to outperform traditional DAFs and ensure longevity. Heavy duty durable polypropylene construction allows operation over a wide temperature range and pH range of 2-13, so the system offers tremendous treatment flexibility. The system’s design guarantees low operational and maintenance costs. Consistent and reliable performance ensures compliance with government regulations.

      The www/RESOURCE DAF system uses DAG (Dissolved Air Generator) technology, which allows the removal of fine insoluble materials by generating 5-12 micron bubbles, the finest in the industry. The DAG system achieves saturation efficiencies that approach 100 percent at low energy consumption. This performance has been documented through upgrades of existing systems that show the new DAG technology improves performance while reducing energy costs by more than 50 percent.
