Stream 11 is bleedoff from recirculating scrubbing medium. Stream 11 is added to suspension fertilizer unit 12. Suspension fertilizer requires water for its manufacture, and water in bleedoff 11 is used instead of fresh water. Thus water shown as 9 is source of water for manufacture of suspension fertilizer. Other materials used to manufacture suspension fertilizer are phosphoric acid 13, ammonia 14, and clay 15. Phosphoric acid is neutralized with ammonia and heat of reaction causes liquid mixture in suspension fertilizer unit to boil. Neutralization of phosphoric acid with ammonia results in the formation of ammonium phosphate. When the solution is cooled, ammonium phosphate crystals precipitate; clay 15 retards crystal settling, and suspension fertilizer 16 is produced.
