Power plant water treatment with polyacrylamide or polymeric aluminium chloride?

Power plant water treatment with Polyacrylamide or Polymeric aluminium chloride, electroplating plant flocculant which one to use?

There are many kinds of electroplating plant wastewater treatment methods, including precipitation method, redox method, solvent extraction separation method, activated carbon adsorption method, membrane separation technology, ion exchange method, biological treatment method and so on.

• for the precipitation method to introduce, precipitation method, choose Polyacrylamide or Polymeric aluminium chloride, if you need samples, you can consult our online customer service WhatsApp: +86 19037152650 Email: xinhuan@xhwtm.com.
• The water quality of the power plant is mainly dominated by heavy metals, which can be generally divided into chromium-containing wastewater, nickel-containing wastewater, cadmium-containing wastewater, copper-containing wastewater, zinc-containing wastewater, gold-containing wastewater, silver-containing wastewater and so on.
• through the addition of Polyacrylamide or Polymeric aluminium chloride
• flocculant will be toxic governance for non-toxic, with h into non-h, recovery of precious metals, water recycling and other measures to eliminate and reduce the emission of heavy metals.

Sewage treatment using polymeric aluminium chloride and Polyacrylamide can be added at the same time?

Sewage treatment using polymeric aluminium chloride and polyacrylamide, polymeric aluminium chloride referred to as PAC, is a yellow or yellow-brown powder solid, with flocculation. Polyacrylamide, referred to as PAM, is a white or powder solid, also has a flocculating and coagulation effect.

So sewage using these two flocculating agents can be added at the same time, will it affect the treatment effect?

• According to water treatment experience, the use of polymeric aluminium chloride PAC and Polyacrylamide PAM is generally not recommended to be added at the same time, because PAC is a flocculant, it needs to have a full mixing time, making the formation of colloids to achieve adsorption, bridging and co-precipitation, and then to achieve the purpose of removing pollutants.
• In addition, PAM is smaller particles to form larger flocculation, so as to achieve the role of assisting precipitation. Therefore, it is better not to add at the same time, because the simultaneous addition will make the agent mixed unevenly, resulting in a waste of chemicals and unsatisfactory results.

Through the above introduction, sewage treatment using polymeric aluminium chloride and Polyacrylamide, first add PAC, so that the agent is mixed evenly (PAC fully mixed 30s to 60s can be) and then add PAM.

Because many factories do not have professional technical personnel to guide, are some ordinary operating staff, if the use of chemicals when adding, do not know the order of addition, it is better to use through the guidance of professionals to add, so as not to cause a waste of chemicals, affecting the treatment effect.
