Sludge dewaterability testing

Accurately model dewatering performance and lifecycle savings

Dewaterability Testing

Simple, bench-scale tests can quickly and accurately model the performance and anticipated savings of full-scale Bishop Solids Management Solutions. Performed by experienced Bishop Water technicians, the tests help identify the best chemical conditioning program to accelerate and maximize dewatering and containment of slurry materials.

From simple jar testing to onsite pilot systems, the tests provide important performance parameters:

  • Ideal polymer or coagulant and optimal dosage;
  • Volume and rate of filtrate released from the material;
  • Percent total solids (dry weight) attained;
  • Time needed to achieve required percent total solids (dry weight);
  • Quality of filtrate and ability to achieve regulatory requirements;
  • Retention of contaminants such as BOD, TSS, phosphorus, nitrogen and metals such as lead, copper, nickel, chromium, cobalt and more.

With this information, the project team can also calculate potential savings in capital and operating costs for full-scale systems, taking into consideration the cost of chemicals, electricity, and hauling/disposal of dewatered solids.

Mobile dewatering system

Bishop Water can also provide a calculation of a system’s carbon footprint and compare it against more energy intensive systems such as centrifuges and belt presses.

For onsite evaluation, a Bishop Mobile Dewatering System can be quickly set up to provide first-hand operational data as an integrated component of the process. The Mobile Dewatering System consists of a trailer-mounted VEPAS system and a Geotube container sized to fit in a 30-yard roll-off bin.
