Media Specifications:
Primary Filtration Media
Color: Black Odor/Taste: none; Physical Form: Granular; Screen Size: 8-20
(US mesh); Specific Gravity: 1.93;
Bulk Density (pounds/cu. ft.): 120
Life Expectancy: 10 - 15 % attrition per year
(due to lost media fines in the backwash cycle)

Under Bed Filter Sand
Keeps riser in place and promotes better flow and even water distribution through media bed and during backwash cycles to lift bed uniformally.

Conditions of Operation:
System Service Flow Rate - up to 35 gpm
Media Service Flow Rate - 5 gpm / sq. ft.
Min/Max Water Temperature: 40º / 80 ºF - 4.4 / 62.8C
Min/Max Water Pressure: 40 PSI / 75 PSI
Warning: Minimum flow rate for unit 8 GPM
pH Range: 5.0 to 9.0
Warning: Install Pressure Reducing Valve (PRV), by code in places, to prevent pressure surges and warranty issues

Caution: Please note the following;
• Proper specifications of tank valve and media will be the key to your success with the proven PYROLOX media. Proper sizing of the valve and backwash flow against the proper tank size and water service flow rate will result in satisfactory media performance. (Be sure the valve has adequate water supply for full backwash cycle.)

• If the media is not properly backwashed it will not lift the 20% necessary to break loose the contaminants of particulate hydrogen sulfide, iron and manganese. Without proper backwash (we recommend a daily backwash) you can quickly foul the bed and make the media useless. Therefore know your water problems and conditions, your PSI and GPM.

• The introduction of any organic link to iron (iron bacteria) or manganese creates a coating on any media or resin and will render the system useless. Chlorination or some form of effective treatment must be established at the origin of the water.

• If the media is not properly backwashed it will not lift the 20% necessary to break loose the contaminants of particulate hydrogen sulfide, iron and manganese fouling and making the media useless. This requires a boosted water flow rate and/or water pressure to the system to function properly.

CAUTION about the proper use of these and any treatment system on a well and water that is not monitored, tested, or treated on a routine basis.

Limitations and solutions: See additional information on problems and their solutions. Please review detailed information in this web site.
