High Coagulant Consumption in Dairy Industry

I currently have a problem with the use of coagulants in a dairy industry (its pH ranges from 4.35 to 11) and drinks as juices.

The current process involves the use of a dissolved air flotation system, as well as the application of coagulants and flocculants. I currently use an iron salt with ACH and the costs have risen almost 10 times due to large dosages at high pH (up to 1200 ppm).

I need a product to reformulate the said coagulant and reduce doses. I am open to your suggestions and products to be able to establish a business relationship that will support me and products to reduce doses in this and new projects that I am attending. Greetings.
