Helping Restaurants See Through the FOG | Greenbiz

The acidity of the FOG eats away at pipes over time, which leads to major failures in sewage infrastructure. This is a constant concern to municipal water districts, most of which charge restaurants thousands of dollars in cleanup costs each time grease traps overflow, in addition to fining restaurants to encourage them to regularly check and clean the traps.

The acidity or alkalinity of wastewater affects both treatment and the environment. Low pH indicates increasing acidity, while a high pH indicates increasing alkalinity (a pH of 7 is neutral). The pH of wastewater needs to remain between 6 and 9 to protect organisms.

5.10 Total Alkalinity | Monitoring & Assessment | US EPA

6/3/2012, · ,Alkalinity, is a measure of the capacity of water to neutralize acids (see pH description). Alkaline compounds in the water such as bicarbonates (baking soda is one type), carbonates, and hydroxides remove H+ ions and lower the ,acidity, of the water (which means increased pH). They usually do this by combining with the H+ ions to make new compounds.

By one estimate, ocean ,acidity, has increased 30 percent from the colonial era. This level is dangerous for shellfish that make up the bulk of the local aquaculture industry. "Certain organisms like oysters and clams that rely on calcium for their shells are unable to thrive in an environment that is too acidic," said Hauke Kite-Powell, a research specialist at WHOI .
