GWT - Unique NatZeo Filtration Media
From Water Treatment Media & Flocculants - Water Treatment Medias
GWT NatZeo treatment media is a low-density, natural and environmentally friendly media typically used in gravity or pressure filters for both drinking water filtration, process water and wastewater reclamation applications. This media provides higher filtration performance, reducing sediment levels to around the 5 micron filtration range. This water treatment media provides significantly greater solids loading capacity of sand and multimedia filter configurations allowing for extended backwash cycle frequencies which reduce operating and maintenance costs and water usage for backwash cycles. The media also has a high CEC (cation exchange capacity) for removal of charged contaminants such as certain trace metals, solids, and trace ammonia in the source water. NSF 61 pending certification for drinking water, FDA General Recognized As Safe (GRAS) Compliant. Available in minimum pallet quantities/truckload/container quantities in 50lb/ 22.72 kg bags, or 1 ton or metric ton sacks.
Product Details
Around the world there is an increasing need for enviromentally safe methods of providing high-quality drinking water and for the treatment of a wide range of commercial, industrial, and municipal water contamination and air pollution issues.
NatZeotm is an inorganic micro porous alumino-silicate material with many unique filtration properties including a high cation exchange capacity (CEC). GWT NatZeo media is a cost effective, environmentally safe solution for the filtration of both water and wastewater treatment.
Physical Properties
- Density (lb/ft³): 50-55
- Bed depth (inches/cm): 24-48in / 61-122cm
- Color: Grey-Green
- Particle Size: 14x40 (.41-1.41mm)
Conditions of Operation
- Service flow (gpm/ft²) PV: 12-18 gpm/ft2 (700-1050 m3/m2d), GV: 4 gpm/ft2 (233 m3/m2d)
- Backwash flow (gpm/ft²):
- PV: 13-17 gpm/ft2 (762.5 m3/m2/d -992 m3/m2d), GV: 13-17 gpm/ft2 (762.5 m3/m2/d - 992 m3/m2d)
- Filter Bed Depth: 36in / 92cm for optimal filtration (depending upon flow rate)
- Freeboard: 50%-55% of bed depth
- Pressure Vessel Filtration Bed Expansion: 30-40%
Gravel Underbed Required in PV configuration, in GV configuration underdrain will need to be configured with smaller apertures than media particle size if no underbed is used to minimize media loss.
Media will need to fully soak prior to initial backwash (12-24 hours).
Application/Industries Served
Water Treatment:
- Turbidity Reduction to 3-5 micron tor water filtration systems
- Removal of heavy metal cations, certain hydrocarbons and other contaminants including bacteria
- Can be used as a direct replacement media for sand filtration system with 2.8x sediment loading capacity
Waste Water Treatment/Pollution Control:
- Waste water ammonia removal in municipal/industrial waste water
- Pollution Control media can increase biological activity, reduce nutrient levels, cut sludge volume and odors. reduce ammonia and BOD levels in ion exchange columns or bed effluent, can be back flushed and regenerated. with ammonia recovered for fertilizer, increases sewerage plant capacity and life cycle.
Radioactive Water Treatment:
- Nuclear cooling and waste treatment of Cesium and Strontium and site remediation/decontamination
Water Treatment:
- Turbidity Reduction to 3-5 micron for water nitration systems
- Removal of heavy metal cations, certain hydrocarbons and other contaminants including bacteria
Aqua Culture / Fishing Industry:
Fish Hatchery water treatment
- Ammonia control
- Bioliltration media
Mining :
- Gas/Odor Removal
- Absorption and Retention of certain dangerous heavy metals and oils in mining waste water
Industrial Oil/Gas Applications:
- Absorbents for oils/hydrocarbon in water and oil spills
Benefits & Advantages
- Cost-effective replacement for sand, garnet & multimedia
- Lower pressure drop for a given flow rate (gpm/ft2)
- High CEC (cation exchange capacity) for ion exchange of charged contaminants (dissolved metals, sodium, ammonia)
- Highest solids loading reduces backwash interval frequency and consumption of backwash water
- Superior filtration performance at high flux rates
- All natural, environmentally safe product
- Low Density media reduces shipping and handling costs
