In summary, the conversation is about designing a machine to clarify and reclaim industrial wastewater. The person is interested in using flocculants for this purpose and is wondering how to select the right type of flocculant. They also ask if there is a universal flocculant that can work for different types of effluents and if it is necessary to neutralize the pH before treating the effluent. There is a video and some resources provided for reference.

Hey guys,

I am interested in designing a machine for clarification (reclaiming) industrial wastewater from a plant. The effluents to be treated would be Spent Degreasing water, spent cnc coolant or other process water.

I would be looking to use Flocculants for this purpose. Please see this video for reference -

My question is how do you select the flocculants? And will there be a possibility of 'One-Floc-Suits-All' type of additive that would work with different effluents?

And is it necessary to neutralize the pH before treating the effluent?

Thanks,
KV

Lots of information on this including a couple of threads on here.

What is the purpose of using a flocculant in industrial wastewater clarification?

The main purpose of using a flocculant is to aid in the separation of suspended solids from wastewater, making it easier to clarify and treat the water before it is discharged into the environment.

How do I determine the appropriate type of flocculant for my specific industrial wastewater?

The type of flocculant needed depends on the characteristics of the wastewater, such as pH, temperature, and the types of suspended solids present. It is important to consult with a water treatment specialist to determine the most suitable flocculant for your specific wastewater.

What are the key factors to consider when selecting a flocculant for industrial wastewater clarification?

The key factors to consider include the type and concentration of suspended solids, the desired level of clarification, the cost and availability of the flocculant, and any environmental regulations that may impact the selection process.

What are the different types of flocculants commonly used in industrial wastewater clarification?

The most commonly used flocculants include inorganic coagulants (such as aluminum sulfate and ferric chloride), organic polymers (such as polyacrylamide), and natural flocculants (such as chitosan and starch).

How do I properly dose and apply a flocculant in industrial wastewater clarification?

The dosing and application of flocculants can vary depending on the type of flocculant and the specific wastewater being treated. It is important to carefully follow the manufacturer's instructions and consult with a water treatment specialist to ensure proper dosing and application for optimal results.
