Emulsified oil, oil droplet size less than 10μm, difficult to separate from wastewater. Because the oil concentration in the wastewater discharged by different industrial sectors varies greatly, such as wastewater generated during the refining process, the oil content is about 150~1000mg/L, the tar content in the coking wastewater is about 500~800mg/L, and the gas is discharged from the gas station.

The quantitative capacity of water to neutralize an acid; that is, the measure of how much acid can be added to a liquid without causing a significant change in pH. Alkalinity is not the same as pH because water does not have to be strongly basic (high pH) to have high alkalinity.

Wastewater, from meat industry requires usually pre-treatment prior to conveying it to the sewer. The slaughterhouse ,wastewater, should be moni-tored for BOD7 or BOD5, CODCr, total nitrogen, total phosphorus, solids, pH value, electrical conductivity and fat ,concentration,. When making the industrial ,wastewater, contract, limit values for these param-

CONCENTRATION,: The process of increasing the dissolved solids per unit volume of solution, usually by evaporation of the liquid; also the amount of material dissolved in a unit volume of solution. CONDUCTIVITY: The ability of a substance to conduct heat or electricity. Electrical conductivity is usually expressed in microsiemans per centimeter.

The scale which is used to describe the ,concentration, of ,acid, or base is known as pH, for power or potential of the Hydrogen ion. A pH of 7 is neutral. pH's above 7 are alkaline (basic); below 7, acidic. The scale runs from about zero, which is very acidic, to fourteen, which is highly alkaline.

Then the fabric is neutralized in an ,acid, bath. The material is then treated with water or ,acid, to neutralize the sodium hydroxide. If the material is held under tension during this stage, it is kept from shrinking appreciably; if no tension is applied, the material may shrink by as much as 25%.
