Current Status:

There is an overwhelming need for a cost effective, functional and technically sound, maintenance free "install and forget" self supporting floating odor emission control covers for lagoon, pond or slurry tanks and in ground organic waste storage areas, enhancing decomposition with least amount of odor release.

Odors generated on livestock farms, by food processing plants, landfills, pulp and paper, petroleum industries etc. are subject to movement downwind, generating increased public concern. Odors and their control, is a complex issue. The most often mentioned compounds, but not limited to, are ammonia (NH3), and hydrogen sulfide (H2S), associated with decomposition of manure, organic waste or other processing emissions.

The anaerobic decomposition or digestion of organic waste such as manure are perhaps the most widely used biological treatments requiring considerable holding volume, therefore exposing a large surface area to vector migration of odors.

Currently, several technologies are available to reduce odors. Unfortunately, simple economics often prohibit such technologies from being implemented. To date, few have demonstrated as being cost effective or practical as claimed. The most common odor management control for manure lagoons is a floating cover made from polyethylene membrane suspended on cables and/or supported by floatation devices, with perforated gas collection pipes, weighted sunken troughs to collect water, sump pumps etc. The main function of such cover is to prevent vector migration of vapors or gases into the atmosphere and to collect methane gas to be disposed by flaring or other means to reduce odor pollution. However elaborate installation procedures, puncture of PE membrane, wind, hail, snow, ice vulnerability, explosive hazards due to static electricity and accumulation of volatile gases, vandalism, dependency on electric power supply and reliance on professional maintenance of electric motors and pumps, contributes to a substantial initial investment and a high operating cost. Failure or damage of only one of the above components makes the whole system non functional

3RD40ACPET - 3RD15ACPET Systems

OCS Inc. has recognized the need for a functional " Install and Forget", yet cost effective, odor control system for liquid and solid organic waste.

OCS Inc.,has developed a functional "Install and Forget" odor control system for liquid and solid organic waste, in collaboration with Dr J. Ronald Miner, Professor and Extension Water Quality Specialist, Department of Bioresource Engineering, Oregon State University, leading Authority in animal waste odor emission and ammonia release. Evaluation tests conducted at Oregon State University have substantiated the effectiveness of the OCS system.

Floating Odor Control Cover for Waste Lagoons, Ponds, Tanks

• 3RD40ACPET - 3RD15ACPET odor control systems are self supporting, modular, pervious floating cover for lagoons, holding ponds or slurry tanks. The proprietary product design, incorporates buoyancy, gas and liquid permeability in one integrated unit system. It complements lagoons anaerobic process, it also provides an aerobic environment, molecular sieve gas adsorption with selective cation exchange. Proprietary materials used and innovative structural design are capable of to withstanding severe weather conditions, wind, ice and snow loads. Realistic odor reduction, product longevity, cost saving installation, nominal maintenance, affordable price, place 3RD40 ahead of any competitive system in the market place today.

Fixed Land Based Odor Control Cover for Landfills and in or above Ground Waste Storage

• 3RD25ACPET odor control system cover is designed for fixed, land based, inground waste storage such as landfills or other organic waste depots. The proprietary product design, incorporates gas and liquid permeability - transmissivity in one integrated unit. It enhances anaerobic decomposition and aerobic oxidization, it provides effective molecular sieve gas adsorption and selective cation exchange proven to reduce odor. 3RD25 base system has a 10 year successful use as a drainage mat in landfill capping, slope stability, thermal barrier and gas venting. 3RD25 structural integrity, severe weather resistance, longevity, labor saving installation are only some of the advantages of the 3RD25 system.

Function Characteristics:

A gas permeable floatation membrane serves to increase the boundary layer between the liquid anaerobic digestive slurry and air thus allowing the formation of an organic crust above. An organic crust is a combination of a gas permeable cover and treatment system. The 3RDB cover increases the boundary layer between the liquid and air, and forces the gases, that are released through an aerobic environment. This aerobic environment, is filled with microorganisms that oxidize offensive gases. In addition the specially designed unique "Bio-Cover" provides Molecular Sieve gas adsorption and selective Cation Exchange to achieve more then 80% odor and ammonia gas reduction.

Conclusion

Odor from livestock production, food processing or rendering, organic waste disposal and industrial processing must be reduced significantly in order to meet environmental challenges and restore public confidence in the integrity and best effort of the food related and chemical industry to comply with regulatory requirements. To remain in harmony with the environment and the public at large, we must strive for better odor pollution prevention and discipline. The issue today, is not "if" or "when" but "how" to reduce odor pollution in the most cost effective manner.
