Can anyone advise re. a suitable method which can be used to remove thread partials in Denim Washing Waste Water Plant?
Much appreciated.

These are cellulosic fibres. These can be removed simply by flocculation followed by sedimentation. Flotation cell and disc filters can also be used. For more details please write to rvsveipl@gmail.com

There are a number of self-cleaning filtration units on the market that involve a fine mesh (finer than 60 mesh), and that clean by use of a traveling cleaner such that the filter is always in service step.
One other option, perhaps, would be to utilize a screen that could be cleaned by air blast, so that less water is wasted.

Micromac UK used to make a rotating screen which had a vacuum and backwash applied. The poresize of the screen was selected depending on what was needed to be removed. If the screen was clean no action was needed. If the screen started blocking it started rotating and a vacuum system removed the foulants, if the water level rose due to further blockage it brought on a backwash system. I don't know if they still manufacture them.

Dear Asanka,
Depanding upon flow there can be sevaral answers, for a less flow say 5000LPH you can use stainless steel mesh in a S.S enclosure around foot valve of pump. for a larger flow you can opt for filter bag with mesh for further large flow use rotating screen with mesh.

Perhaps a rotating screen with auto washdown. The screen could be sized appropriately to match your particular flow rates and filtration needs.

Please inform on the following:
Flow average at the removal point

Good Afternoon Asanka,
Ascertain micron size and consider matching micron size bag filtration in stainless steel housings.

Dear Asanka,
A few years ago I had the same issue with a similar wastewater and successfully used a DAF system.

Dear Asanka,
I agree with John on aplying Dissolved Air Floatation (DAF) to remove fine fibers and lint from textile washing wastewater.
Fine screens and filters would work to some extent but are likely to clog up requiring frequent cleaning and/or maintenance.
