Corrosion of Metal, especially Iron

Corrosion is defined as the chemical or electrochemical degradation of metals due to their reaction with the environment. The corrosion of iron, better known as rusting, is an oxidation-reduction process that destroys iron objects left out in open, moist air. In the United States alone, it is estimated that the cost of corrosion, in equipment maintenance, repair, and replacement, exceeds $300 billion per year. What kinds of chemical treatments, surface coatings, or combinations of metals will prevent the corrosion of iron?

When iron metal is exposed to oxygen and water, a familiar result is observed-rust. The rusting process consists of several steps. In the first step, iron is oxidized to iron(II) ions, Fe2+, and oxygen from the air is reduced to hydroxide ions, OH-. This oxidation-reduction reaction takes place via two separate but simultaneous half-reactions (Equation 1 and 2);

Oxidation half-reaction: Fe(s) → Fe²⁺(aq) + 2e-          (Equation 1)

 
Reduction half-reaction: O₂(g) + 2H₂O(l) + 4e- → 4OH-(aq)    (Equation 2)

 
Combining the oxidation and reduction half-reactions gives the balanced chemical equation for the overall reaction of iron, oxygen, and water (Equation 3). Notice that two iron atoms are oxidized for every oxygen molecule that is reduced-the number of electrons gained by one oxygen molecule is equal to the number of electrons given up by two iron atoms.

2Fe(s) + O₂(g) + 2H₂O(1) → 2Fe²⁺(aq) + 4OH-(aq)   (Equation 3)

 
Fe²⁺ and OH- ions may combine to form solid iron(II) hydroxide, Fe(OH)2 (Equation 4). This is almost never observed, however, because iron(II) hydroxide reacts further with oxygen and water to form hydrated iron(III) oxide, Fe2O3•nH₂O, the flaky, reddish-brown solid known as rust (Equation 5).

Fe²⁺(aq) + 2OH-(aq) → Fe(OH)₂(s)         (Equation 4)

 
4Fe(OH)₂(s) + O₂(g) + xH₂O(I)→ 2Fe₂O₃•(x+4)H₂O(s) Rust    (Equation 5)

Our product can remove rust and carbon remover in metal, especially iron. It's contain substances that inhibited corrosion (decreased the rate of metal oxidation/ over etching).

COAGULATION AND FLOCULATION IN A WASTE WATER TREATMENT

Coagulated, coagulating : to change from a fluid into a thickened mass; curdle; congeal.

Our Product :

DIACOG 70

Coagulation Agent for Waste Water Treatment

Packing : @20 Kg/can

The DIACOG 70 treatment has been formulated for coagulation in waste water treatment process. DIACOG 70  is work in conjunction with floculation agents (DIAFLOC 100) to destabilized particles together into larger aggregates so that they can be more easily separated from the water. Diacog 70 and Diafloc 100 are generates a floating, high solids sludge which is able to be removed from the water by sedimentation and/or filtration. 

APPLICATION

1. Diacog 70 and Diafloc 100 conjuction with pH of waste water treatment, before using these product, cek pH waste. 

pH 7-8 :                                                    Chemical Feed Rate into Booth Water:

DIACOG 70                                                4 Liter, flow with the wind 5-10 minutes

DIAFLOC 100                                             6 Liter, flow with the wind 5-10 minutes

pH 9 :                                                                    Chemical Feed Rate into Booth Water:

DIACOG 70                                                5 Liter, flow with the wind 5-10 minutes

DIAFLOC 100                                             7 Liter, flow with the wind 5-10 minutes

pH 10 :                                                      Chemical Feed Rate into Booth Water:

DIACOG 70                                                6 Liter, flow with the wind 5-10 minutes

DIAFLOC 100                                             8 Liter, flow with the wind 5-10 minutes

b.     If flock have been formed,  stand for ±10-15 minutes, to separate between the sludge with water

c.     After appearance of the water is clear, filtration sludge and put in packaging (Tank or rafia bag).

DIA ADDITIVE pH                               To adjust pH

CONTROLS

-          pH with pH paper or pH meter

-          Turbidity with turbidity meter.

-          Jar Test

            

turbiditymeter dan alat untuk Jar Test pada pengecekan flok di lapangan.

pH Control:

NEUTRALIZER is added to keep the pH of the water circulation system.

Coagulation:

DIACOG 70 is the primary coagulant chemical in this process. This material is conjuction and activated by the DIAFLOC 100, therefore the ratio between the two chemicals in solution is critical to proper coagulation.

Flotation:

DIAFLOC 100, Flocculent is added to enhance floatation of the sludge and improve dewatering in a floatation cell, that produces a micro floc which actively interacts to produce a high solid floc in waste water system. 

Result : 2 phase of Waste --> Sludge will be drying and send to PPLI
