CONTRACT MANUFACTURING NEWS
Beware of any scenario where the word “partnership” is used only to obtain a better price and/or more aggressive terms, as this is the origin of failed relationships. A true partnership should define terms that balance the risk and reward for each party.
As new technologies are incorporated into POC diagnostics, the challenges of taking product from design to full-scale commercialization increase. Is your supplier model as efficient as it could be?
With price competition and cost pressures squeezing the profitability of medical devices, supplier networks are the latest target for cost reductions — and rightfully so. Complex supplier networks add costs without adding value.
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.
硝化有氧过程分为两步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.
