Wastewater, flows from the home to the septic tank through the sewer pipe. The septic tank treats the ,wastewater, naturally by holding it in the tank long enough for solids and liquids to separate. The ,wastewater, forms three layers inside the tank. Solids lighter than water (such as greases and oils) float to the top forming a layer of scum.

An example of chitosan-grafted magnetic nanoparticles used for oily wastewater treatment is demonstrated in Figure 2. In some advanced wastewater treatments using membranes, some chitosan nanoparticles are embodied into ultrafiltration and nanofiltration membranes to reduce chemical oxygen demands, color, metal ions, and to enhance the antifouling properties [ 27 , 28 , 29 ].

And after leaving medium water pool, the waste water enters Fenton oxidizing tower to oxidize and degrade the non-degradable pollutants. The waste water after Fenton oxidizing tower will flow into Neutralization and degassing pool with alkali liquor added to neutralize waste water. And then the bubble in waste water is removed by stirring of fan.

The wastewater must be agitated with mixers. High energy mixing is required initially to ensure that the coagulant spreads throughout the water. When flocculation is in progress the mixing energy is reduced to prevent the mass of particles from separating again. Stage 3. Once floc is beginning to form, a polymer chemical is added to the wastewater.

This is particularly the case if the effects of ,acidic, scrubber wash water are also included (Stips et al., 2016). Strong acid deposition can also affect the ability of the oceans to take up CO 2 : a modeling study in the Baltic Sea indicates that each mole of strong acid deposited results in a 0.8 mole reduction in CO 2 uptake ( Turner et al., 2017a ).
