Nitro, WV - Case Study
OR-TEC recently published two case studies on high profile installations. These case studies appeared both in print and online in more than 33 publications. The first case study completed was on a OR-TEC 2.2 meter Gemini Belt Press installation in Nitro, West Virginia. The belt press, installed in 2017 is exceeding all required performance criteria specified in the engineers bid documents while being trouble-free and easy to operate.
A SUPERIOR SLUDGE DEWATERING SOLUTION:
OR-TEC’S 2.2 METER WIDE GEMINI BELT PRESS DELIVERS HIGH DRY SOLIDS THROUGHPUT AND AN EXCELLENT DRIER FINAL CAKE RESULT FOR HISTORIC CITY OF NITRO, WEST VIRGINIA.
NITRO, WV:
Located between two of the Mountain State’s largest cities of Huntington and Charleston, Nitro was originally born as a "BoomTown" during America’s mobilization for World War I for production of gun powder. Nitro WWTP is nestled near a coal burning power plant and services approximately 4,500 customers within the regions’ 7,178 population.
OR-TEC / NITRO SOLUTION:
Having researched Belt Press system options by visiting a number of different installations over nearly three years, Danny Lewis, Nitro’s WWTP Plant Superintendent, discovered a unique Belt Press system in operation at a wastewater treatment plant in Williamstown, WV. That plant’s superintendent, Bob Stirling, noted that it was a Gemini Belt Press from OR-TEC, INC. a leading integrated manufacturer of advanced wastewater treatment equipment for the municipal and industrialmarketplace.
OR-TEC / GEMINI BELT PRESS SYSTEM SPECS:
At 2.2 meters wide, the Gemini Series Belt Press is ideal for medium to large size WWTP’s. The double belt system is constructed of stainless steel vs. galvanized or painted steel due to it being a far better material in wet/corrosive environments. The press combines a gravity drainage zone, a squeezing zone, and high pressure shear zone to provide a large dry solids throughput of up to 1,500 lbs. per hour, low polymer usage, high solids capture rate, and an excellent final cake.
The unit has a large flocculation tank with a variable speed mixer which allows the sludge and polymer solution to be thoroughly mixed. This flocculation process is critical to the dewatering process as it helps separate the water and the sludge. The variable speed mixer allows operators to easily change the mixing energy which helps ensure the best possible flocculation and dewatering.
