Acidic drain cleaners usually contain sulfuric acid at a high concentration which turns a piece of pH paper red and chars it instantly. Apart from grease and hair, an acidic drain cleaner containing sulfuric acid can be also used to dissolve tissue paper inside water pipes. Acidic drain cleaners usually contain sulfuric acid at high ...
Brine draw: Water is directed through a jet pump, which pulls salt water from the brine tank, before the water and brine pass through the resin bed in the normal direction, if co-current, or in the reverse direction, if counter-current. [12] The output of this typically thirty-minute process is discarded through the drain hose.
Corexit products have been used in oil spill response activities since the late 1960s. [14] Early products in the line included Corexit 7664 [4] and Corexit 8666. Corexit 9527 is one of the first modern concentrate dispersants and has been in use since the mid 1970s. Corexit 9500 was designed to replace Corexit 9527.
Oil dispersant mechanism of action. An oil dispersant is a mixture of emulsifiers and solvents that helps break oil into small droplets following an oil spill.Small droplets are easier to disperse throughout a water volume, and small droplets may be more readily biodegraded by microbes in the water.
A drain cleaner, also known as drain opener, refers to a person, device, or product used to unblock sewer pipes or clear clogged wastewater drains.This term typically applies to chemical, enzymatic, or mechanical tools such as commercial chemical cleaners, plumber’s snakes, drain augers, bio-enzyme solutions, or toilet plungers.
This allows the spent solution to degrade prior to disposal and is especially important if a large portion of peroxide was used in the preparation. While some institutions believe that used piranha solution should be collected as hazardous waste, others consider that it can be neutralized and poured down the drain with copious amounts of water.

A dense non-aqueous phase liquid or DNAPL is a denser-than-water NAPL, i.e. a liquid that is both denser than water and is immiscible in or does not dissolve in water. [1]The term DNAPL is used primarily by environmental engineers and hydrogeologists to describe contaminants in groundwater, surface water and sediments.
