Conclusion

DelSorb impregnates zeolite with a 4.1% quaternary amine solution. We call this product DS-200. Our competitors use clay as an alternative to zeolite, presumably for swelling and economic considerations. Anthracite coal is included our competitors relationship of coal/clay amine is 70/30. Delsorb DS-200 does not swell. Delsorb HS-200 has 333 % more active product per cubic yard than that of blended organophilic clays.
