Fresh water Pollution

salinity

Industrial wastewaters which tend to contain high

levels of inorganic salts formed by various industrial

processes.

Road drainage waters which contain salt used to melt

snow and ice on highways.

Irrigation which dissolves salts from the soil.

Seawater penetration into rivers during high tides and

low runoff.

Brines from oil wells and mines which are sometimes

released into fresh water.

Refrigeration

Freezing

Acid

Bactericide

this slows down, but does not eliminate, bacterial.

and chemical reactions; reaction rates at 4 “C are about a quarter of the rates at 25 “C

this reduces bacterial and chemical reactions even further

lowering the pH greatly reduces bacterial activity

many bacterial agents have been used to

eliminate completely the activity of microorganisms; chloroform & mercury(I1) chloride are the most common

to separate

dissolved

components

from those

present in

suspended

matter.

Grade 1:

11 µm

- Extended range of sizes includes 10 to 500 mm diameter circles

- Traditionally the grade is used in qualitative analytical

separations for precipitates such as

lead sulfate

,

calcium

oxalate (hot)

, and

calcium carbonate

.

Grade 4: 20-25 µm

Extremely fast filtering with excellent

retention of

coarse particles and

gelatinous precipitates

such as

ferric

hydroxide and aluminum hydroxide

.
