Description:

Dicyandiamide Formaldehyde Flocculant is polycationic copolymer flocculant used?for decoloring-clarification of sewage?and high-colority?waste water from textile dyeing mills, dye-works mills and paper mills. It is specially working high performance with the dyeing wastewater containing the hydrophilic dyes (reactive dyes, acid dyes, disperse dyes etc.), less dosage, the color clear, fast speed, high processing liquid clarification of the settlement, but also reduce the composition of COD, improve the COD removal rate. Can offer further flocculating effect, if jointly used with the?inorganic flocculating agents including aluminum sulfate, poly-aluminum chloride and?ferric chloride, or the polymer group such as polyacrylamide and acryiic polymer. Being a positively charged cationic flocculating agent, the flocculant?neutralizes?the negatively charged pollutants in the waste water to form insoluble complexes in water.? The experimental results indicate that the dicyandiamide formaldehyde resin not only on hydrophobic dispersed dye color removal effect is excellent and of hydrophilic dye (reactive dyes, acid dyes) in addition to the effect of color is also very good, the dyeing wastewater showed that, less dosage, in addition to the obvious, settling velocity and the processing liquid high clarity, while also reducing COD components, improve the removal rate of COD, COD removal rate can reach to more than 98%.

Competitive Advantage:

1	Dicyandiamide?formaldehyde flocculant has?strong reduction of decolorization as well as?COD.
2	Has functions?of de-color high-colority effluent from textile and dyestuffs mills.
3	Treating wastewater with soluble and insoluble dyestuffs, such as Reactive, Acid, Disperse, Direct Dyestuff etc., can get very high performance.
4	Specially used to treat color wastewater from textile and dyeing industry, pigment industry, printing ink industry and paper industry.
5	Fast?sedimentation, better flocculation.
6	Less sludge produced than other inorganic coagulants.
7	Soluble in water, safe, non-toxic, hydrolytic stability, is not sensitive to the change of pH value, anti-chlorine. Harmless, no-flammable and non-explosive, it can be stored at room temperature, it cannot be placed in the sun.?

Application Methods:

1	Have solution of 2-2.5%, by mixing water and dicyandiamide formaldehyde flocculant,?add it?directly in the sewage, stir a few minutes after sedimentation or flotation can cause the effluent decolorization obtained after the clear liquid.
2	Adjust the effluent sample pH value to 8-10, that can better improve the decolorization effect of dicyandiamide formaldehyde flocculant.
3	When?deal with the high chroma and COD of wastewater, can use polymaluminum chloride (PAC) together(attention not mixed use). This can effectively reduce the waste water decolorization processing cost, reduce COD,?how to add PAC should be according to the actual situation, it is best to make the professional and technical personnel to develop a good solution.
