Another type of pilot is The Volute Thickener (no photo provided): This reduces the water content some so the sludge can be further processed.

We encourage these pilots and also encourage interested parties to visit an operational installation.

CLA-VAL designs and manufactures a wide range of products to meet specialized flow control applications, including active pressure management and fountain control. The CLA-VAL 700 Series Roll Seal line, with its all 316L SS construction, was designed for unique applications and is used around the world in such places as amusement parks, casinos, office buildings, mines and athletic venues. The Roll Seal valve carries approvals for UL, FM, PUB and NSF applications. Our flush valves are utilized in lines that have seasonal use or limited use at the time of new construction. CLA-VAL’s active pressure management products include ECO timers, switches and pressure reducing valves. Our specialty products line also includes PUB Approved float valves, solenoid control valves and electronic control valves. CLA-VAL’s depth of experience and engineering expertise in developing products for diverse industries and complex applications enables us to meet the needs of increasingly unique and demanding flow control requirements.

COUNTY ALTERNATIVE WATER SUPPY

This project by McDavid Associates expands water service in Greene County and Farmville with new distribution piping, elevated tanks and booster pumps.  Mechanical Equipment Company supplied a coordinated system of components with Aurora split case pumps, Allen-Bradley VFDs and SCADA-VFD coordinating controls by EG controls.  Specialty valves by OCV and APCO added to the system control functions designed into this system.  Each pump is complete with a 100 hp motor and sized to deliver 1300 gpm.  EG Controls built the control panel with maximum flexibility.  Under normal operation, the controls automatically sequence valves and start the pump motors with the VFDs.  However, if automatic function is lost through PLC or SCADA failure, all system control valves and pumps can be operated manually to maintain the water supply to the system of elevated tanks and distribution piping.  In the event of variable frequency drive failure, power can be bypassed through solid state, reduced voltage soft-starters.  Now working in concert with Greenville’s water system, Farmville and an extended area in Greene County will have a reliable water supply for years to come.  – Bob McCollum

U.S. Corrugated’s  linerboard mill is located near Cowpens, SC.  The 700+ ton per day facility recycles both old corrugated containers and mixed papers to produce both corrugated medium and linerboard.

From their website, “ The mill is truly an environmentally friendly operation and was recently called “ one of the most environmentally friendly and sustainable mills in the world” by Paper 360 magazine.  For example, besides being able to divert a massive amount of wastepaper from being buried in landfills, the mill is quite unique in the industry in that it discharges NO process water into any streams, rivers, or municipal sewers.  U.S. Corrugated is the recipient of several  environmental awards including the SC Environmental Shining Star Award  and DHEC’s 2000 Best Industry Recycling Program.”

With the NO discharge of process water, all water is cleaned and recycled continually in their paper making.  This return process water must be cooled from a high temperature of ~ 130 F to around 100 F. MECO  was approached with an opportunity to offer a process solution to cool the process return water before being reused in the mill to make paper.

We proposed a closed loop system  with Delta cooling towers, Tranter & EG Controls heat exchangers and Aurora pumps to control temperature by bypassing  thru a 3-way  control valve.

The mill had problems with cooling towers in the past due to various environmental issues, but we were able to offer a unique product with Delta Cooling Towers.  Delta offers  a non-corroding Polyethylene [ HDPE ] double wall shell with a 15 year warranty and meets all new ASHRAE 90.1 energy efficiency standards.  The heat exchangers were Tranter’s  plate and frame, model # GXD-051-237 which offered a U-Factor and over 1000 Btu/hr.sg ft  F.  The pumps selected were Aurora model 411 split case. The pumps are over 80% efficient over the operating curve.

With MECO’s complete capabilities, we were able to offer an engineered solution from concept to design, fabrication through to startup.  The system was put into operation the first week of June  to everyone’s satisfaction.

This is a perfect example of  MECO’s mission statement to provide our customers with exceptional engineered solutions and services.  We accomplish this: by partnering with our customers and principals from conception through implementation for our mutual benefit and by building lasting relationships with our principals, employees and customers.  Ben Crider  – Engineered Sales

After completing the usual submittal process, NPC shipped (3) pumps and AFDs’: (1) rated at 700GPM @  240 ft TDH and (2) rated 350 GPM @ 240 ft TDH. Installation went smoothly; however, during start up, one of the pumps exhibited vibration greater than satisfactory. This not an unusual situation for vertical turbine pumps. The usual solution is to provide additional bracing to the base/support head to change the natural frequency of the complete assembly. In this case, however, National Pump decided to employ a unique solution using a set of “tuning plates”. These tuning plates were installed between the pump support head and the motor and the result was as predicted and satisfactory without the unsightly braces. See photo 2 for the tuning plates – the two shiny discs.

The project start up was completed in the summer of 2010. We appreciate the opportunity, and assistance provided by City of Asheville, Brown And Caldwell and Buckeye Construction.  -  Walter Lee

Fairbanks Morse (Pentair Water) was chosen to design, develop and manage these 11 enormous pumps. It had already worked with the Army Corps of Engineers on the 17th Street pump station, and these pumps are similar to those in the 17th pump station, which move 3,600 cubic feet per second of water. However, the West Closure Complex pumps move an additional 3,850 cubic feet of water. Together, the 11 pumps will move close to 9 million gallons of water per minute.
According to Mike Wiley, GIWW team leader with Pentair -  Engineered Flow, the planning for the project began years ago. “The project ran about four years, from spec stage to delivery of the final pump in December.”
