Penggunaan Reaktor UASB

COCOK• Asupan listrik dan influent stabil

• Kadar COD influent tinggi

• Industri F&B, pulp&paper

TIDAK COCOK• Komunitas kecil• Terlalu banyak padatan,

gugus lemak, gugus protein dalam influent

• A UASB is not appropriate for small or rural communities without a constant water supply or electricity. The technology is relatively simple to design and build, but developing the granulated sludge may take several months. The UASB reactor has the potential to produce higher quality effluent than Septic Tanks (S.9), and can do so in a smaller reactor volume. Although it is a well-established process for large-scale industrial wastewater treatment and high organic loading rates up to 10 kg BOD/m3/d, its application to domestic sewage is still relatively new.

• It is often used for brewery, distillery, food processing and pulp and paper waste since the process typically removes 80 to 90% of COD. Where the influent is low strength or where it contains too many solids, proteins or fats, the reactor may not work properly. Temperature is also a key factor affecting the performance. or fats, the reactor may not work properly. Temperature is also a key factor affecting the performance.
