According to our many years of Engineering experience, starch waste-water mainly includes:

(1) Corn starch wastewater: high water consumption, high COD (8000-30000 mg/L) and high SS (3000-5000 mg/L);

(2) Potato starch wastewater: high acidity of wastewater produced by starch residue fermentation.

We mainly use UASB, anaerobic contact digestion and photosynthetic bacteria to treat starch wastewater effectively.
