Process Description

Weir Tank Treatment:

Water is delivered from a customer source tank through a pipeline for chemical injection, followed by the Big D retention loop. The water is then sent to custom weir tanks, where oil, water, and solids are separated. The clean water from the clear well of the weir tanks is then filtered through an automated system, designed in-house specifically for the oil and gas sector. The filter uses activated glass media and efficient backflush operations to ensure that the highest quality of clean water is produced for the customer.

Dissolved Air Flotation (DAF) Treatment:

Water is drawn from a customer source tank or vessel and sent through a pipeline for chemical injection. The water then passes through the Big D retention loop and into the DAF vessel, where air bubbles are added to help separate oil, water, and solids. Once the desired level of cleanliness is achieved, the water is discharged from the clear well to the customer. An optional Big D filtration system can be included in the design to polish the water in case of unexpected changes in condition.

Disinfection on the fly:

Water is being transferred from the customer's source pond to the Big D on-the-fly unit, where it is dosed with the prescribed amount of biocide. This unit is set inline with the pipeline to allow sufficient residence time for the chemical reaction to take place. Moreover, a trailer of biocide is kept on site and refilled as needed to complete fracturing operations.

All facilities are monitored around the clock and a comprehensive report of operations and KPI metrics is sent to each customer daily. In addition, periodic reporting of KPIs is done via messaging of the customer's choice.
