Waste Water Treatment for Ink, Dye, and Paint Waste Streams

  Wastewater Treatment Wastewater streams containing ink and dye do not treat well by traditional coagulation and flocculation and generally will not treat at all using a biological process. However, these wastewater streams can be treated using a blend of sodium bentonite clay mixed with a coagulant and a flocculent. The bentonite clay entraps and removes the dye, ink, and paint. Jar testing of paint, dye and ink waste streams makes a great demonstration of the ability to remove these compounds. The floc takes on the exact same color as the dye, ink or paint and settles to the bottom ... » Read More

Using a Bentonite Clay Body Feed

Bentonite Clay Body Feed A body feed, such as bentonite clay, can be added to waste water when it is difficult to form an adequate floc. Poor floc formation can occur when the waste water is low in suspended solids.    Without proper formation of floc particles, the undesirable constituents of the waste water such as solids, oil, grease, heavy metals and color are not removed as desired. A typical body feed is bentonite clay. A bentonite body feed will add solids and assist in the formation of floc particles. The floc particles will attach to solids, oil, grease and heavy ... » Read More
