*Equipment for Processing Process Water* 1. Influent - Water coming in 2: Process - Water carrying out the job 3. Effluent - Water going out 1:21 1. Bring in water 2. Clean it up 3a. Send out Effluent (to expel unwanted water) or 3b. Recycle clean water (to reduce Discharge costs) 7:22 Drum Filter +- Less Surface Area than a Disk Filter 12:07 Krofta IA - Injected Air DAF - Dissolved Air Flotation
There are a couple, economic, and quality reasons QUALITY Screens and cleaners can remove solid contamination like glass, metal, plastic etc. But they cannot remove the soluble contamination in the process water. THickening stock removes a lot of process water and whatever contamination is in it. The fibre is then diluted with fresh water, so that any remaining contamination, is diluted. ECONOMIC By thickening stock, (say from 2% to 6% as an example), you need less storage space, so a sinle chest rather than three, or a small chest rather than a large.. This will reduce your capital costs not just for the chest itself, but also the cost of providing the foundations.

Disperser are good but costly ....is kneader could be used instead of that hot desperser ? I was reading but confused
