Wastewater and Sludge Conditioning Success Story

ROCHESTER, NY, Summer 2006 -- Continuous accurate treatment of water is required in all phases of its use. Most population centers have water treatment plants for cleaning and conditioning used water before it is returned to the environment.

The Monroe County Department of Environmental Services maintains the Frank E. VanLare Waste Water Treatment Facility. Located on the southern shore of Lake Ontario, VanLare has a total treatment capacity of 660 MGD and is currently running around 100 MGD. The plant uses Chlorine in the form of 12.5% Sodium Hypochlorite for disinfection (killing harmful microorganisms) before the final discharge of the wastewater.

The VanLare plant runs 24/7. A peristaltic pump was being used to feed the Sodium Hypochlorite. Plant operators were not satisfied with the inconsistent and unpredictable hose life, or the time required for hose change out. They had safety concern for skin contact and inhalation.

In addition, extra costs were incurred because of wasted chemical, down time and inventory carrying costs.

Looking for a better solution the Environmental Service team wanted to try Eclipse Series external gear pump from Pulsafeeder, a unit of IDEX Corp. The sealless, leak free design addresses the safety concern. The reliable Eclipse front pullout design means normal wear components can be changed in minutes.

The Eclipse E75 has proven its reliability with over 8,000 hours of continuous run time.

In addition to pumping Sodium Hypochlorite, The VanLare Environmental Services Team will be installing three Eclipse E25 pumps into the Ferric Chloride station. Ferric Chloride is used for phosphorus removal.

For latest training seminar for this technology was held Oct. 10-12. For more training information, see www.pulsafeeder.com or www.pulsa.com
