Dear Readers:PSI Process and Equipment a leadingmanufacturers’ Rep Company focusedon addressing the area’s mostchallenging water issues, has beenawarded contracts to supply allstainless steel NOVA Disk Filters for thetertiary treatment of wastewater prior toultraviolet (UV) disinfection at two NewJersey wastewater treatment plants.The new NOVA Disk Filtersmanufactured by Water Technologies

of Tampa Florida, are key to thesuccess of the facilities to meet thelocal regulatory limits for discharge.The NOVA Disk Filter uses thepatented concept of ‘dynamic-tangential filtration,’ an innovativeapproach to applying disk filtertechnology for tertiary treatment. Thisproduct filters effluent from the plantprocess in order to remove suspendedsolids. Through the patented processthe filter’s disks are in continuousrotation forcing the filtration to occur atangles less than 90°, allowing forhigher capacity and efficiency. TheUltrascreen® Disk Filters wereselected based on NOVA’s smallestfootprint, all stainless steel mediainstead of fiber/cloth, less than 1%reject, operator friendly design, longerlife, lower maintenance, and local PSIcommitment to service and support.

PSI Process and Equipment provides support to theNew Jersey Water Environment Association MiniWorkshop Committee for seminar entitled “Conservingyour Wastewater/Potable Water Budget Dollars” on Jan14-15, 2014. There are three locations, one each inNorth, Central and South New Jersey. There are a totalof 12 hours TCH credits for all “S”, “C”, “T”, “W”, &“N”NJDEP Licenses. Mr. Denis Rehse, Mr. RogerParkhurst and Mr. John Corkery will be presenting DiskFilter Technology “Dynamic-Tangential Filtration,” aninnovative approach to applying disk filters for tertiarytreatment of plant effluent.

collection well and exits through the outlet pipe. The wetedge of each disk is sealed to form a positive barrier toprevent filtered effluent from mixing with the influent. Theintegrity of the effluent is assured. Another benefit of theUltrascreen® is performance optimization. Rotationaldisk speed, wash cycle timing, and the level of fluid inthe feed zone are all variable. The Ultrascreen® istherefore the right choice for all types of treatment plantsand operating conditions. Performance optimization likethis is unique to the Ultrascreen Disk Filter. Installation ofthe new Nova Disk Filter systems in New Jersey beganin 2013 with both facilities planned to be in operationbefore summer 2014.

Nova Disk Filters are used for the tertiary treatment ofwastewater, water reuse, polishing, Total SuspendedSolids reduction (TSS) and primary effluent. PSI is theauthorized distributor in the New York/New Jersey area,providing engineering support, start up, and service.

When the influent level in the feed box rises to a presetlimit, a sensor actuates operation of the backwashsystem, with no interruption to the filtration process. Eachdisk has a dedicated spray header for efficient washing.The backwash reject from each set of disks is collectedin a common 304 or 316 stainless steel trough, it thenexits the filter through a stainless steel drain and returnsback to the head of the plant or to the biological process.
