DuPont Nylon in Victoria, Texas recently initiated operations at its Biological Treatment Unit. The sludge being produced was particularly difficult to dewater. In fact, belt filter press effluent, at 8.5 percent solids, could not even pass the paint filter test required to allow the material to be landfilled without costly solidification. Worse yet, solids capture was in the neighborhood of only 50 percent which, if not remedied, would cause an overload on the entire Biological Treatment Unit.
BioCel Technologies worked with the team of DuPont dewatering specialists to effectively and efficiently solve the compounding problems of extensive disposal costs (caused by low quality filter cake) and extremely low solids capture on the belt filter press. By conditioning the sludge with Pelletized EcoFiber (formerly known by the product name BioCel), the filter cake improved to 12.5 percent solid, passed paint filter testing, and was landfilled without the use of a costly bulking agent. Not only was the use of a bulking agent avoided, but the vast dewatering improvement effected by EcoFiber resulted in a 23.5 percent reduction in the amount of waste DuPont was discharging to the environment. Taking only disposal volume into account, DuPont's net savings were projected at over $160,000 annually.
Further, solids capture was increased to over 90 percent immediately and later fine tuned to meet design requirements, thus preventing overload on the Biological Treatment Unit.

K-Sorb Eco Particulate
A highly absorbent cellulose product used to absorb an control liquid spills in industrial settings. It is manufactured from recycled cellulose fiber and is non-selective (Eco ) in what it absorbs. It is a non-carcinogenic, low dust alternative to clay, vermiculite, and d. e. Ideally suited for spill cleanup on land, K-Sorb Eco Particulate can absorb 3 to 5 times its weight in liquid spills, making it over 400% move absorbent than clay. A 10 gallon spill would require ne 22 lb. bag of K-Sorb, or 88 lbs, of clay. Lightweight and highly absorbent, K-Sorb Eco Particulate is an excellent choice for solidifying liquids and stabilizing sludge. Its use can reduce inbound transpiration costs and material handling by 75% versus clay, while reducing hauling and disposal cost 40%. It has high btu value (8,484 btu/lb) and qualifies under RCRA for cost effective and permanent disposal as fuel through incineration. Inorganic absorbents such as clay, fly ash, vermiculite, and d. e. do not, making their disposal means more limited and costly. K-Sorb Eco Particulate is available in 22 lb. and 10 lb. bags.

K-Sorb Eco Fiber
A highly absorbent cellulose product used to solidify liquid waste and stabilize sludge for transportation and disposal on remediation projects such as tank cleanouts, lagoon dredging, and pond closures. This specialty fiber is ideal for absorbing free liquid in roll-off boxes and can be disposed of as a solid waste. K-Sorb also satisfied UPA test requirements (i.e., paint filter and TCLP tests) for waste prior to disposal. K-Sorb Eco Fiber can absorb an amazing 13 to 17 times its weight in water and/or oil, meaning less clay, corn cobs, rice hulls, and lime kiln dust. Not only does K-Sorb Eco Fiber reduce and the amount of waste requiring disposal up t 46%, it is made from 98.5% recycled fiber that otherwise would go to a landfill. Furthermore, this product has 8,484 but/lb and burns to less than 3% ash, making it ideal for incineration projects. Inorganic absorbents such as clay, fly ash, and lime kiln dust do not burn which limits disposal options to more costly methods. K-Sorb Eco Fiber is available tin 30lnbf, and 40 lbs compressed bags measures 18 inches x 22 inches x 12 inches.

K-Sorb Hydrophobic Fiber
A loose cellulose absorbent which is oleophilic (readily absorbs oil-based liquids) and hydrophobic (does not absorb water). It is used to absorb hydrocarbons, chemicals, oils, and greases on land and on open water. K-Sorb Hydrophobic Fiber is an excellent choice for solidifying chemical waste and stabilizing oil-based sludge prior to transportation and/or disposal. K-Sorb Hydrophobic Fiber effectively separates free oils from water and can be used to remove contaminants from shores, lakes, rivers, ports, marinas, lagoons, and ponds. It passes US EPA Paint Filter Test Method 9095A after absorbing 13 times its weight (1.8 gallons per lb) in oils, making it much more cost efficient than other cellulose absorbents, sphagnum peat moss, and polypropylene. K-Sorb Hydrophobic's high capillary wicking action instantly attracts hydrocarbons, locking them into its hollow fibers and allows for quick cleanup before the spill spreads. K-Sorb Hydrophobic fiber passes the TCLP and prevents the leaching problems associated with clay, d. e., and polypropylene. Once saturated with hydrocarbons it has absorbed, K-Sorb Hydrophobic's additional 9,809 but/lb and low ash content make it an exceptional candidate for disposal as an alternative fuel source at cement kilns, fossil fuel plants, and traditional incinerators. This product is available in 30 lb. compressed bags measures 18 inches x 22 inches x 12 inches

K-Sorb Hydrophobic Particulate
A densified version of K-Sorb Hydrophobic Fiber. It has the same characteristics as the fiber but it is pourable tin nature and more resistant to windy conditions. K-Sorb Hydrophobic Particulate can absorbs 4 times its weight (over half a gallon per pound) and is used for controlling and remediating CERCLA liquid hazardous waste on land and on open water. It is a cost effective alternative to Absorbent W, polypropylene, and peat moss. In addition, K-Sorb Hydrophobic particulate is used as a filter media to remove oils and greases from contaminated water sources. it is available in 22 lb. bags (approximate 1.5 CF) of loose particulate.
