Investigation of a New Phosphate Removal Process
Investigation of a New Phosphate Removal Process

The above process is based upon ,removal, of ,phosphorus, from secon- dary effluent containing an average ,phosphorus, content of 10 mg/1, with a product water to contain not more than 0. 32 mg P/l. If the process is used for polishing effluent from which a portion of the ,phosphorus, has been removed, a lower cost may result.

As noted above, a growing interest in removing phosphorus from wastewater for water quality improvement and nutrient recycling has led to two major processes to recover phosphorus using crystallization reactions: the struvite (magnesium ammonium phosphate hexahydrate) process and the brushite (dicalcium phosphate dihydrate) process.
