How to Treat Gelatine Wastewater

According to the gelatine production method, we know that gelatine is mainly produced by alkali method, which produces large star wastewater in the production process, and the wastewater is characterized by high alkali, high calcium, high chlorine, high COD, complex water quality and large water volume.

According to years of practice, our company summarized a set of practical treatment methods. That is, coagulation destabilization, flocculation and sedimentation method.

Coagulant is mainly polymerized aluminum chloride and sulfate class. In the Water Treatment coagulation process, the coagulant will be added to the metal ion hydrolysis and polymerization reaction process, at this time, the colloidal particles in the water can be strongly adsorbed hydrolysis and polymerization reaction products. The adsorbed positively charged polynuclear complex ions can compress the double layer, reduce the potential, so that the colloidal repulsion is reduced to achieve the purpose of particle destabilization. Flocculant is mainly Polyacrylamide, polyacrylamide belongs to the organic polymer flocculant, mainly through the adsorption of bridging effect of colloidal particles adsorbed to the molecular chain, the formation of large flocculants.
