Sulfide control
Novozymes Biologicals has introduced a new product for the control of sulfide odors. The product, BI-Chem® DP 110, can metabolize reduced sulfur compounds thereby controlling the malodors they generate. The product contains facultative anaerobes capable of oxidizing reduced sulfur compounds as an energy source in aerobic and anoxic environments. It is available in a 25 lb pail and in convenient 1 lb SoluPaks. The product is offered through select distributors and directly through Novozymes Biologicals.

Corrosion, odor control
The use of hydrogen peroxide and iron salts are both proven methods for treating sulfide for odor and corrosion control in collection systems. US Peroxide has integrated these two methods in a synergistic fashion that results in improved performance and lower iron consumption. The proprietary technology is known as Peroxide Regenerated Iron - Sulfide Control™ or PRI-SC™. Along with long-duration control of sulfides to low levels, the technology provides benefits that include rapid oxidation, improved influent quality and benefits for clarification and digesters.

Organic odor neutralizer
Ecosorb® Natural Organic Odor Neutralizer removes a wide spectrum of odors from the air without using fragrances or harsh chemicals. Instead, it uses patented technology to eliminate unwanted odors by neutralizing them, rather than simply masking them. The product from Odor Management Inc. is typically diluted with water and sprayed into odorous areas in an atomized mist. The droplets electrostatically attract the molecules that form the odor, then capture and neutralize them, diminishing their volatility until they are reduced to their lowest possible form. The system is effective with harmful gases, including hydrogen sulfide, sulfur dioxide, ammonia, ethyl mercaptan and methyl mercaptan.

H2S monitoring
Hydrogen Sulfide monitoring in the inlet and outlet of wastewater odor control scrubbers presents difficulties due to the detrimental affect of condensing water on H2S sensors. Monitoring systems using sample conditioning systems have resulted in systems that are expensive and require regular operator service. Analytical Technology has developed a system for H2S monitoring in wet gas streams that solves these problems. The company's new D12 scrubber monitor combines a unique "water tolerant" hydrogen sulfide sensor with a simple sensor purging system that allow continuous monitoring of H2S in condensing air streams. Wet H2S sensors used in this system are housed in a special acrylic flowcell designed for connection to 1'' scrubber sampling lines.

Odor control
The new GE Betz ProSweet™ family of products act immediately at the source to neutralize hydrogen sulfide, mercaptans and other acidic and reduced sulfur compounds to reduce or eliminate troublesome odors and toxic buildup. Easy to feed, the products require no pH adjustments or special equipment. ProSweet products contain no metal salts or oxidizers to corrode equipment, lower pH levels, remove biological nutrients, create handling problems or generate sludge that can increase waste disposal costs. The formulations can be automatically misted into the air to control odor emissions from outdoor waste piles. Formulations are also available to control or minimize a wide range of nonsulfide odors.

H2S monitor
Isco has introduced the Advisor™ Purgeable Hydrogen Sulfide Monitor, which provides continuous sensing of purgeable H2S in wastewater flow streams. The monitor measures dissolved H2S and regulates existing chemical dosing or injection systems to assure cost-effective odor control. Housed in a self-contained NEMA 4x (IP67) enclosure, the instrument's primary output is a 4-20 mA signal for feedback control of the chemical feed pump used to inject destructor chemical into an offending stream. Programmable alarms can be set to trigger corrective actions when abnormal conditions occur.
