Hydrogen sulfide is a common component in wastewater treatment plant off-gases (e.g., biogas) and waste gases from certain industrial processes. It is highly toxic and odorous. Therefore, its release into the atmosphere is regulated. In addition, it is very corrosive, which can result in costly damage to equipment and piping systems used in biogas handling. Several technologies exist for removing H2S from gas streams, but many suffer from drawbacks such as insufficient removals, complexity or high cost.

Carbon block is used in a wide variety of applications and performs a wider range of filtration tasks than other products. How carbon block is engineered will determine its use.
The Kenosha Water Utility treatment facility, located on the shores of Lake Michigan in Wisconsin, needed to upgrade its two plants to meet the expanding water needs of the community it services. Continuous microfiltration helped meet those needs.
The following is some basic information compiled from industry experts at diverse companies. Additional information is available at the contact information provided.
The Basic Types, Materials and Applications for Various Filter Cartridges.
During the 2000 Olympic Games, U.S. Filter Australia/Vivendi Water supplied a wastewater reclamation plant that recycled sewage and rainwater runoff at the games site. Part of the purification process involved the use of reverse osmosis (RO) technology.
A 200,000 gallon per day (gpd) advanced microfiltration system treats secondary wastewater effluent for reuse as process water for Toppan Electronics, Inc. in San Diego, Calif.
In the early 1990s, the Milford-Trumbauersville Area Sewer Authority in Bucks County, Pennsylvania, recognized the need to upgrade the existing sewage treatment plant. This was necessary to increase capacity and to meet future more stringent requirements set by the Pennsylvania Department of Environmental Protection for Unami Creek.
How can someone protect himself from consuming water contaminated with Cryptosporidium or other microorganisms? One durable and competitively priced option is ceramic filters.Until recently, the United States was essentially a carbon filter market, in that chlorine, dirt, foul taste and odor were thought to be the only problems with drinking water. With the advent of the Cryptosporidium parvum outbreak in Milwaukee in 1993, the general public and water treatment dealers started to question the quality of municipally treated water and private wells.
Filtration is an important part of most water treatment systems. Filters range from simple cartridge systems to large commercial/industrial multi-tank systems, not to mention the large municipal systems that filter drinking water.
