Abstract
A method of and apparatus for controlling precipitation in evaporation ponds containing brine is provided wherein brine to be concentrated is introduced into a pond at at least one brine entrance, this brine being mixed in the vicinity of the entrance with bine present in the pond by enhanced brine mixing apparatus such that precipitation of salts occurs and salt deposits form in the vicinity of the entrance. This salt deposits collect in a collection basin at the floor of the pond. Brine present in the pond can be close to saturation or even saturated with respect to at least one of the salts contained therein. Deposits present in the collection basin can be removed to a location external to the pond by removal apparatus preferably including a mechanical scapper and conveying or transporting apparatus. A submerged source of compressed air producing bubbles or a motorized propellor mixer may be used to enhance the mixing of the brines near the brine entrance. When a source of compressed mixing is used to enhance mixing, a perforated pipe wherein the compressed air exits through the perforations or holes can be used for this purpose.
