ODORSCRUB Wet Scrubber
The ODORSCRUB PTS line of packed tower scrubbers is designed to be a low cost, highly effective system for removing Hydrogen Sulfide and/or Ammonia from municipal wastewater applications. The systems are based on neutralization of the H2S into a caustic solution. Recirculation will increase the concentration of the gas in solution and decrease the quantity of scrubbing solution required. The ODORSCRUB PTS system provides the following benefits:
 EFFICIENT: Efficiencies of 99% and better can be achieved in many situations with standard models. For more difficult conditions, the height of the packing bed can be increased to achieve the desired results. |
| LOW STATIC PRESSURE DROP: Well-designed airflow distribution, packing and scrubber solution hydraulics reduces the resistance to air flow. This results in a pressure drop of approximately 3" w.c. range, which in turn allows for the use of a low horsepower fan. This will save on electrical and operational costs. |
| LOW WATER CONSUMPTION: When recirculation is used, make-up rates are designed for a maximum of 1 gpm per 1000 cfm. In many cases the site gas concentrations do not require this amount and thus rates of 0.5 gpm per 1000 cfm are common. Please contact us for your specific application requirements. |
| MAINTENANCE FREE / CORROSION RESISTANT: All interior components are fiberglass-reinforced plastic. The gas and wash solution see no metal. |
| RUGGED CONSTRUCTION: Similar to Enduro's FRP Adsorption systems, ODORSCRUB PTS scrubbers have extra thick continuous corners and seamless corners and walls. Packing support systems are well designed for long-term reliability with low operator intervention. |
| LOW COST: With 14 standard sizes for volumes up to 65,000 cfm, there is a standard pre-engineered size to efficiently match all volumes. New drawings and tooling are not required thus lower capital costs verses other technologies are likely. |
| PROVEN PERFORMANCE: These have been produced and have long-term proven performance since the 1960's. Enduro is proud of its commitment to quality and performance. |
| CUSTOM TOWERS: If these standard systems do not fit your needs, with our experience and knowledge we are happy to help you with your specific treatment requirements in designing a custom system. |
| MULTIPLE TECHNOLOGY INTEGRATION: In many cases not one technology will result in the best performance and costs. Enduro designs and manufactures a full line of different treatment technologies. For example, in cases where there is a very high level of H2S, it may be more cost effective to utilize an ODORSCRUB PTS followed by a HAWK odor control absorption system. |
Process Description
1. High velocity contaminated odorous gas enters the large plenum chamber wherein the velocity is reduced to provide even gas distribution across the bottom of the packing section.
2. The gas flows slowly through a bed of specifically selected packing, which creates a tortuous labyrinth that causes the gas to be completely mixed and reacted with the caustic solution. The counter current flow of gas and solution maintains an absorption driving force throughout the entire depth of the packing bed.
3. Fresh make-up solution is added to the solution being recirculated to compensate for evaporation and to keep the absorbed contaminant concentration in an effective absorption range. In the spray chamber the caustic solution is evenly distributed over the top of the packing bed by a single non-clogging spray nozzle.
4. Clean gas flows through a high efficiency mesh pad, which prevents mist carryover.
5. The caustic solution is collected in the recirculation sump, which has been sized large enough to provide a constant positive head for a recirculation pump.
