Filtration Sand

Low UC to less than 1.4 for precise sizes
Consistent chemical and physical properties
AWWA B100 and NSF 61 quality assured with an effective testing plan: 1) prepare a sampling plan 2) thorough in-house testing 3) outside independent testing
Convenient packaging and timely delivery for both domestic use and export
AWWA B100 AND NSF 61 quality assured. Sampling plans, in-house size tests and independent testing assure the filter media meets size, chemical and physical requirements
Sand meets PA DEP disposal sand specification (0.30-0.60mm UC < 3.5)
