The Clari-DAF system also equates to chemical cost savings. When compared to a conventional clarification plant, Clari-DAF consumes less coagulants and polymers – eliminating the increased chemicals required and mixing necessary to achieve larger, heavier floc that will settle.Water treatment plants utilizing the.
Different process alternatives have been proposed for selective separation between apatite and contaminants (carbonates and silicates) present in phosphate ores. Magnetic separation, calcination and gravity separation processes are methods that present low efficiency and high cost. Flotation is the most common process.
