MAP - Process for Separation of Magnesium-Ammonium-Sulphate

In municipal WWTP using digestion, crystallization can often lead to a blocking of pipes and dewatering units. By using a special patented ACAT process the Struvit crystals can be separated. The sludge properties are dramatically improved.

Further advantages are:

• Massive reduction of the amount of precipitant and flocculent

• Increase in sludge dry content, consequently: significant reduction in disposal costs

• Increase in the throughput of sludge in sludge dewatering
