Abstract

An experimental method for lowering total dissolved solids in wastewater. This thesis project has been undertaken by Aaron Crotts in partial fulfillment of requirements for the degree of Bachelor of Arts in Environmental Studies. The problem undertaken in this thesis is to apply an experimental technique in wastewater treatment in hopes of reducing the total dissolved solids. Total dissolved solids consist of various dissolved ions in water such as calcium, magnesium, sulfur and sodium. In looking at one industry in particular a local Ice Cream manufacture, the problem with total dissolved solids is evident because of their manufacturing process, an abundance of dissolved solids is discharged in their wastewater. Limited by state permits on their discharge, the industry will eventually have to limit total dissolved solids. In applying an experimental method using ammonium hydroxide in the influent wastewater of the plant the total dissolved solids can be decreased. Due to the particular treatment process the manufacturer undertakes and the properties of the ammonium hydroxide which raises the ammonia and total suspended solids level, application of the ammonium hydroxide to the influent was chosen over the effluent. In performing experimentation varying concentration of ammonium hydroxide were used to access the effectiveness of the ammonium hydroxide. At the highest ammonium hydroxide, the total dissolved solids were lowered by 52.7%, and even at the lowest concentration it was lowered by approximately 6.0%.
