How to Save Money and Avoid Issues in Your Membrane Water Treatment Plant by Using a Pilot During the Design Process

Posted by Julie Nemeth-Harn on Mar 15, 2017 10:46:00 AM
Membrane Water Treatment PilotPilot systems are the most cost-effective method of testing membrane plant designs. The basic idea is that a pilot system can be implemented at a fraction of the cost of the full system, and then full implementation follows after the design has been optimized and potential obstacles have been worked out.

Improving Design Concepts

Whether you are talking about low pressure membranes, membrane softening, desalination, or brackish water reverse osmosis, a pilot system can be used to test performance, identify potential problems, and establish optimum solutions. At Harn R/O, we have determined that pilot systems improve the final design and eliminate most installation and operational issues. The result is a faster implementation without delays or costly alternate design modifications once the work begins.

Pilot Systems Must Simulate Full-Scale Conditions

Membrane Treatment Pilot Systems can be small single element test stands or larger systems that more accurately simulate the actual design parameters that will be applied in the full-scale plant. These larger pilot systems do not cost much more to rent or buy than the single element test stands, but the data obtained during the pilot test will be much more accurate and useful. The objective of a pilot system is to generate usable data for a well-developed design, which is why we use pilot systems that most accurately simulate all of the full-scale design parameters. Since the quality of the data is critical to a trouble-free design, the scalability of the pilot system is essential.

Pilot Systems and EPA Regulations

In some designs, the EPA requires water suppliers to conform to the EPA Information Collection Rule. Also, many states have their own requirements to pilot a membrane process prior to full-scale implementation. To accomplish this, pilot systems become an invaluable asset. Pilot studies allow the system optimization of a variety of parameters, including:

  • Design Flux and Recovery
  • Chemical Dosage
  • Cleaning Parameters and Frequency
