Injections and infusion fluids must be manufactured in a manner that will minimize or eliminate extraneous particulate matter. Parenteral solutions are generally filtered through 0.22 pm membrane filters to achieve sterility and remove particulate matter. Prefiltration through a coarser filter is often necessary to maintain adequate flow rates, or to prevent clogging of the filters during large-scale manufacturing. A talc or carbon filtration aid (or other filter aids) may also be necessary. If talc is used, it should be pretreated with a dilute acid solution to remove surface alkali and metals.

Water discharge is typically handled by the existing treatment and discharge facilities, or treated by carbon filtration prior to discharge where the quantity of recovered water has been minimal. LNAPL is periodically pumped out of the tank and transported to a recycling facility. Periodic tank gauging and product transfers avoid the accumulation of LNAPL to the point where it could be inadvertently discharged with the water.

Prior to construction of the Ft. Eustis pest control facility, TRADOC requested the U.S. Army Medical Bioengineering Research and Development Laboratory (USAMBRDL) to investigate the feasibility of using an activated carbon filtration/absorption system to treat the pesticide-laden wastewater. The final system design was to 1) not be manpower intensive 2) not require extensive analytical monitoring, and 3) be compatible with both the types and quantities of pesticide wastes produced by a typical pest control facilty. The initial research was funded jointly by EPA and TRADOC. 

An inexpensive commercial carbon filtration system (Car-bolator) was found to have considerable potential in solving the waste treatment problem at pest control facilities. The Carbolator operates by the recirculation of wastewater through a bed of activated carbon. 

In both of these field tests, the application of thin-layer chromatography was essential for characterizing the pesticides in the water and in monitoring the progress of their removal by the carbon filtration system. 

The Carbolator carbon filtration system offers an economical and dependable means by which small waste generators can effectively treat their pesticide-laden wastewater. The system is portable and can be assembled from commercial items with a capital cost of about 3,000 (1981 costs). The system was simple to operate and with the aide of the thin-layer chromtography, the system was easy to monitor.

At a pharmaceutical manufacturing facility in New York, an organoclay-carbon filtration system was installed to treat wastewater contaminated with emulsified white petroleum, stearic acid, fatty acid stearates, fatty alcohols, mineral oils, and oxyethylene ethers and stearates. The system consisted of 159 kg of organoclay and 86 kg of activated carbon. The entire system cost 8000 (D17267S, p. 29). 

The vendor states that due to the cost of spent carbon replacement, the cost savings for prefiltering wastewater through one tank of organoclay prior to activated carbon filtration is approximately 7115 per year, but probably depends on throughput (D14900I). 

Most metals cannot be treated by ATDU technology. Soils may require pretreatment if they contain oversized materials or greater than 30% moisture. The off-gas stream may require additional treatment by activated carbon filtration or thermal oxidization to remove light hydrocarbons. 

Liquid sugar is readily available as an aqueous solution, usually at 67% w/w (67°Brix) at 20°C. It is manufactured by dissolving granulated sugar in water at an elevated temperature. The product may then be further refined by carbon filtration and de-ionisation. It may then be further treated using ultraviolet (UV) light to reduce microbial contamination.
