Pump Services, Inc., a Gettysburg, PA contracting firm
servicing large industrial and commercial companies, worked with a client
who was faced with almost daily fouling of pumps, disruptive downtime, and
high manpower costs at a wastewater plant that is part of their larger
facility. Raw soda ash, introduced into the wastewater stream as a
commonly used method to control pH, was the main culprit. While
inexpensive, safe, and able to be sewered without EPA concern, it is
actually also raw scale! The needs of this large facility required the
use of over 200 pounds of raw soda ash per hour, depending on the season.
Pump Services, Inc. designed a solution to these problems using patented TWT Deposit Control technology, and implemented it in the second quarter of 1999. For the 2" copper water inlet line, which serves the entire system, including the blend tank, they installed a 2" TWT Commercial/Industrial Deposit Control System. After a period of three months, they discovered that while the existing scale problem had had diminished and new scale had been kept from collecting, the result was not as significant as hoped.
However, based on the results they did obtain, Pump
Services knew that they could fully succeed with this treatment if they
correctly configured an appropriate multi-point treatment scenario.
Taking advantage of the easy movability and flexibility of the TWT products,
they relocated the 2" Deposit Control System to the 1" outlet line
of the blend tank. They then installed a replacement 4" Deposit
Control System to treat the 2" water inlet line, instead.
The increased signal power available from the upsized controllers provided the necessary signal penetration on both lines, without changing the plumbing configuration (2" and 1" Reaction Chambers used with the upsized controllers maintained the existing pipe configurations), and the post-tank treatment assured that the treatment benefits are carried throughout the wastewater stream infrastructure.
Within a short period of time, distinct results were evident. Then, by the end of one year:
Direct yearly savings gained by installing the TWT Deposit Control Systems:
Indirect labor costs reflect pipefitters and miscellaneous equipment necessary to dismantle piping for high pressure clenaing. Downtime costs reflect the cost of diverting the effluent waterfrom the wastewater facility's own waste handling system to the township's system.
Pump Services, Inc. and their client state that while these figures are remarkable, they are, in fact, conservative. Clearly, they are extremely satisfied with the results that the TWT deposit control products have produced, and look forward to implementing their use whenever they can, in preference to any other treatment option.
