Water is the one of the most important resources on planet Earth. It is vital that we protect the quality of our water, and make sure it is safe for everyone who needs it throughout the world. At Fluid Metering Inc. we understand the seriousness of making sure water is treated properly, and offer valveless piston pumps for the complete denitrification of effluent wastewater. The amount of fresh water that is available on our planet is limited, so it is important to treat it properly.
Hazards of Nitrogen in Untreated Wastewater Effluent
In untreated wastewater effluent, nitrogen is present that in high concentrations can pose major environmental concerns when released into bays and watersheds. As nitrogen is an end-product of the bacterial metabolism of ammonia, it can deplete dissolved oxygen in receiving water. It also stimulates the growth of aquatic plant and algae growth which causes hypoxia and also blocks sunlight from reaching submerged marine life which creates a condition known as eutrophication. Nitrate compounds in drinking water can also cause the human health condition known as methemoglobinemia which alters the oxygen-carrying capacity of hemoglobin. Due to these hazards, it is important that the levels of nitrogen created during the wastewater treatment process be reduced before the effluent is discharged into the environment.
Denitrification Using Methanol
Using a process known as denitrification, water facilities convert the excess nitrates into nitrogen gas, which is then vented into the atmosphere instead of being released into waterways. One of the most cost-effective denitrification options is with the use of methanol. Methanol is used in wastewater applications as the carbon source that breaks down the nitrates. Because methanol is volatile, wastewater treatment facilities need specific metering pumps that are specially designed to dispense the chemical. Our CeramPump® line of valveless metering pumps is ideally suited for this. Constructed from inert and corrosion resistant ceramic parts, with only one moving part in the fluid path, it is highly reliable and extremely precise with an output variation of only ±1% of set value. The use of sapphire-hard, dimensionally stable, ceramic internal components allows precision manufacturing with tight clearances and the elimination of multiple check valves provides a metering pump that can self-prime down to the micro-liter range and never lose prime.
This year we will be at WEFTEC 2016 in New Orleans, LA from September 26-28. This is the premier water quality conference for professionals looking for water quality solutions and the latest industry innovations focusing on protecting our water and environmental resources. At booth #7416 our product experts will be on hand displaying our unique valveless pump technology and answering questions. For more information visit our tradeshow section or contact us.
