NEP Series
Heavy metals in waste water of factories have been deposited and separated as hydroxides. There are plentyof methods based on a type of industry and a kind of toxic materials. It may be fairly difficult to be less than
figure of regulations by such general treatment. The best procedure is demanded by a type of industry,
facilities and treatment equipment, an actual figure of regulations. We have developed “NEP Series” astreatment reagents for heavy metal ions. The NEP Series reagents react with various heavy metal ions toform insoluble salts, which are easy handled to dispose. The NEP Series reagents for heavy metal ions havewide applicable and extraordinary performance.
Characteristic of NEP #08-H
1. It is suitable for treatment of Cu and Ni ions, especially.
It is possible to treat EDTA, ammonium chloride, ammonium persulfate, ammonium citrate, andpyrophosphates that are unable to be treated by usual neutralization way.
2.

Elimination rate of heavy metals is extremely high.
This way has high elimination rate, compared to the conventional neutralization method.

3.

Easy handlingYour present facilities can be used, to which just be added the reagent.

4.

Wide applicable
Effective pH range is 7~13.
Several sort of heavy metal ions coexisted (two valences and more ions) can be simultaneouslyremoved.

5.

Do not cause to increase COD
Due to use just a proper dose to a concentration of heavy metal ions, the active ingredients combine
completely with metal ions to be fixed, so that they are not exhausted into water layer.

How to use NEP #08-H
1.

First it is adjusted to an appropriate pH by neutralization.
Heavy metal ions in a solution are to be flock as much as possible by way of neutralization. This
process can effectively progress the following chemical reaction as well as saving amount of #08-H.

2.

The point in use#08-H is usually added to pH adjustment tank. #08-H is liquid. Use of dedicated tank is desirable.
Do not mix to other chemicals. Both of neat solution and dilution can be used. #08-H is possible tobe diluted freely based on an ability of adding pump and a size of tank.

3.

Solution against a formation of fine flock
A color of reagent is rarely remained in upper liquid. The phenomenon is that the reaction productwith #08-H is very fine and uncondensed. One of the solutions is to use 1-3 times of inorganic
aggregation auxiliary.

4.

Use of polymer coagulant
It is the same as usual aggregation and precipitation way by neutralization.

Polymer coagulant

can be added after an addition of Condensation auxiliary agent, if you use. Do not use polymer
coagulant when all solutions are filtered off, because filters may be clogged.
5.

Addition amount of #08-H
The equimolar amount of #08-H is used to total heavy metal ions in waste water. Standard is that
0.1 mL (2-3 drops) of #08-H is used in 10 mg/L concentration of single heavy metal ion. Practicalwaste water containing several kinds of heavy metals, however, do not give theoretical result. Pleaseask to our NEP sales engineers about the reagent grade and addition amount. We can determine thebest mode by a laboratory test.

Please read MSDS before use, although NEP #08-H is not a poisonoum substance nor a dangerous object.
