It can be placed in a non-hazardous landfill or buried on site where permitted by local ordinances.
410HP is of similar chemistry and is in a family of SulfaTreat products used in the wastewater industry to remove hydrogen sulfide from gas streams. Reacted SulfaTreat has passed every stringent environmental test and EPA regulation including the Fish & Shrimp bioassay test for toxicity and EPA's Toxicity Characteristic Leaching Procedure (TCLP).
The product offers a high removal capacity, eliminating the need to be regenerated. Change outs are safe as there is no personnel exposure risk to high pH liquids, strong oxidizing agents, or pyrophoric material and there are no foul odors.
The product is effective at low to high velocities because of the uniform particle size and shape, which eliminates channeling. In addition, it provides consistently high removal efficiencies regardless of wide variations of pollutants entering the system. It selectively removes hydrogen sulfide and light mercaptans without undesirable side reactions typical of some competitive products.
Predictable and consistent bed performance allows change-outs to be planned and budgeted. The process does not require expensive monitoring and control equipment. Since the process is not adversely affected by varying operating conditions, SulfaTreat 410HP systems lend themselves to unattended operations.
The media can be kept for an indefinite period of time, under normal storage conditions, without the loss of effectiveness. It can be stored outside if protected from direct weather elements. Being non-hazardous and non-toxic, it requires no special safety equipment.
Performance
Laboratory and field studies have demonstrated the hydrogen sulfide removal capacity of SulfaTreat 410HP. Typical vessel outlet profiles of H2S starts at non-detect for over one-half the bed life with a very gradual increase in outlet H2S, creating a self-alarm for replacement of the media.
The media is used in fixed bed reaction vessels operated, preferably, in the down-flow mode with water-saturated gas or air. However, up-flow modes can be used where no entrained or condensed liquids are present.
Systems using the product can be designed to work in the presence or absence of oxygen and at any humidity level. Ideally, the gas stream contains free oxygen and a relative humidity of 100 percent or water saturated.
The Sulfatreat - OCtrademark odor control systems use the new 410HP media. The company guarantees performance in partial to fully humid gas, typically achieving >99.9% H2S removal. Complete systems are available for all flow rates and contaminant levels.
