With MEPC.227(64), the International Maritime Organization formally adopted a new standard for the treatment of offshore sewage. More specifically, the guidelines call for a reduction in the amount of TSS, or total suspended solids. Obviously, maritime vessels and offshore platforms are compelled to comply. In doing so, they are also compelled to find a solution that achieves the benchmark using proven technology that integrates easily with the simplest long-term operation, minimal maintenance and most sensible economic impact. For many, the solution to this new guideline is the OMNIPURE™ Series 64 from De Nora.
The PACT system combines biological treatment and carbon adsorption into a single, synergistic treatment step, resulting in significant cost savings and performance advantages over other systems.
The Type-Approved BALPURE® electrolytic disinfection ballast water treatment system is the preferred method of ballast water treatment for LNG/LPG carriers, crude / product / chemical tankers and bulk carriers.
WHITE PAPERS AND CASE STUDIES
FLIR ThermaCAM™ GasFindIR™ Camera Spots Methane Leaks, Prevents Gas Venting, Keeps Air Clean
Waste treatment companies are increasingly turning to energy suppliers to create more streamlined waste disposal, treatment, neutralization, and recycling processes. The FLIR GasFindIR gas detection infrared camera is used to support these processes by providing immediate and tangible results. This application note describes how these gas detection infrared cameras are utilized to capture methane leaks, prevent gas venting, and keep air clean in a Norwegian landfill.
Air / Gas Mass Flow Meter Improves Wastewater Treatment Processing Efficiency
One of the most common processes in wastewater treatment is the activated sludge method, which biologically treats the wastewater through the use of large aeration basins. This process requires the pumping of compressed air into the aeration basins where a diffuser system ensures the air is distributed evenly for optimum treatment. The energy needed to provide compressed air is a significant cost in the operation of a wastewater treatment plant.
PerforMedia™ Oil Removal Media
PerforMedia™ oil removal media replaces walnut shells in media filtration systems. Manufactured from materials not subject to agricultural limitations, the media is able to handle five times the amount of oil before requiring backwash; is able to maintain feed concentrations of greater than 500 mg/L while producing effluent well under 10 ppm; and can be used on a wide range of oil API and elevated temperatures.

The Use Of Walnut Shell Filtration With Enhanced Synthetic Media For The Reduction And/Or Elimination Of Upstream Produced Water Treatment Equipment
Researchers set out to find a substitute for black walnut shells for oil/water separation due in part to the seasonal availability of black walnuts shells. Additionally, a media with improved performance was needed.
Water Treatment Challenge
In the Castilla oil field in the Acacias township in Colombia, Siemens is partnering with Ecopetrol to set up a system that will purify about 40 million gallons of water daily, equal to the average water consumption of a city of 100,000 people.
SAGD Produced Water Treatment System Case Study
Water treatment and steam generation are critical to in situ oil production. An oil sands producer in Northern Alberta, developing a new central process facility, required that the water treatment system use water efficiently to meet operational and sustainability objectives. The system supplied would need to maximize reuse of the treated produced water and minimize waste generated while providing quality water to the boilers for steaming.

In a country with more than 5 million inhabitants within its 710 square kilometer border, space becomes a premium. As one of the most densely populated countries in the world, Singapore must rely on new and innovative ways of thinking to combat the lack of land availability in order to support its growing urbanization and infrastructure needs.
About Nutrient Removal
Nutrient removal from wastewater consists of treating wastewater to remove nitrogen and phosphorus before it reenters natural waterways. High levels of nitrogen and phosphorus in wastewater cause eutrophication, a process where excess nutrients stimulate excessive plant growth such as algal blooms and cyanobacteria. The decomposition of the algae by bacteria uses up the oxygen in the water causing other organisms to die. This creates more organic matter for the bacteria to decompose. In addition, some algal blooms can produce toxins that contaminate drinking water supplies.
As authorized by the Clean Water Act, the National Pollutant Discharge Elimination System (NPDES) permit program regulates point sources, such as municipal wastewater treatment plants, that discharge pollutants as effluent into the waters of the United States. In recent years, many of the States’ environmental bodies have lowered nutrient limits to arrest eutrophication. Maryland’s effort to protect the Chesapeake Bay and its tidal tributaries is perhaps the most notable example of nutrient removal in the US. Nutrient removal continues to be a growing area of focus for wastewater treatment throughout the world.
The removal of nitrogen and phosphorus require different nutrient removal processes. To remove nitrogen, the nitrogen is oxidized from ammonia to become nitrate through a process called nitrification. This process is then followed by denitrification where the nitrate is reduced to nitrogen gas which is released to the atmosphere and removed from the wastewater.
Nitrification is a two-step aerobic process which typically takes place in aeration tanks. Denitrification requires anoxic conditions to encourage the appropriate biological conditions to form. The activated sludge process is often used to reduce nitrate to nitrogen gas in anoxic or denitrification tanks.
Phosphorus can be removed biologically using polyphosphate accumulating organisms (PAOs) which accumulate large quantities of phosphorus within their cells and separate it from treated water. Phosphorus removal can also be achieved by chemical removal. Once removed as sludge, phosphorus may be stored in a land fill. However, many municipalities and treatment facilities are looking to resell the biosolids for use in fertilizer.
