Wastewater managers and operators are tasked with the goal of removing as much Toatl Suspended Solids or TSS as possible from the wastewater stream at lowest possible cost. This removal may be necessary to meet regulatory requirements or simply cost avoidance. Whatever the case may be there are 10 steps that can be taken to assure the maximum performance possible by a dissolved air floation or DAF system. All of these 10 items are focused on controlling the water parameters before the water enters the DAF.
The water treatment professional, whether they are operators, vendor representatives or managers are often tasked with the removal of Total Suspended Solids (TSS) from a waste-stream. This removal may be necessary in order to meet regulatory permit requirements or simply cost avoidance. Universally the goal is to remove as much solids as possible at the lowest cost.
The following rules may be utilized in a wide variety of industrial wastewater applications. And I admit to a bias toward dissolved air flotation (DAF) over a traditional clarifier for solids removal. Why? Because a DAF is easier and quicker to trouble-shoot and it is often the nature of solids that they can be made to readily float. To a degree these rules may be applied to the municipal field, however my focus is industrial as that is where the interesting work is! Industrial wastewater comes in many forms from the simple to the complex. And by boiling TSS down to these rules hopefully I will help you achieve better treatment results.
