EcoSense International Filtration Technology

ESI MBPP

Our standard medium for passive stormwater filtration, ESI MBPP, is a proprietary
polymer manufactured to ESI specifications. It is manufactured by techniques which
produce a very large surface to volume ratio. The filtered particle rating is 5 micron but
the product is loaded into ESI cartridges in a way that produces high flow rates (58
gallons/minute/square foot @ 1-foot head pressure).
ESI MBPP is our most economical filter medium and is well suited for high traffic
Urban sectors. ESI MBPP not only removes oil and grease, but the associated heavy
metals, fine sediments and organic particles plus the nutrients bound with them.
Independent certified NELAP environmental laboratory testing was performed to
evaluate the efficiency of ESI MBPP for stormwater filtration. The tests included EPA
410.4 COD (Chemical Oxygen Demand) and an EPA 8015 Mod. (Total Petroleum
Hydrocarbons by GC). Independant testing in Italy and New Zealand produced similar
results.

The results were as follows:

** EPA 410.4 COD: 98% of the inorganic solids were recovered!

** EPA 8015 MOD. "Total Petroleum Hydrocarbons" test: Showed that the ESI
filter removed the tested hydrocarbons to at or below the available detection limit
of 250 micrograms per liter.

ESI MZ
Tailored clays have been used successfully for a number of years to absorb organic contaminants.
ESI MZ, because it is not a clay medium, but an alumino silicate, is a better alternative. When water
passes through a clay medium, the clay particles expand reducing the inter-particle space and
lowering the permeability of the clay medium. Indeed, the tailoring process itself, due to coagulation
of the tailoring agent may cause a further reduction of permeability. The ESI MZ alumino silicate is a large network of open channel ways, similar to a sponge, with uniform holes and a high cation
exchange capacity. Unlike clay particles, this structure is rigid and stable (even under aqueous
conditions) allowing more contaminants to be absorbed in its open channel ways.
Examples of the chemistry ESI MZ can be effective in removing from waste streams:

anthracene naphthalene benzene non-ionic surfactants chloroform
penenthrene creosote oil/grease ethyl benzene pentachlorophenol
diesel fuel PCE Flourene pyrene fulvi acids solvents toluene humic acids indeno pyrene methylene chloride THM's aluminum magnesium antimony manganese
Arsenic mercury barium nickel cadmium Selenium calcium silver chromium tin
