PTG-520® Answers Dialysis Provider’s Call for a Lightweight, Cost-Effective Solution to Activated Carbon Tanks

    Dialysis providers have yearned for an alternative filtration technique that eliminates hazardous chlorine prior to their Reverse Osmosis (RO) machine in a lighter, more easily maneuverable package. The existing design which incorporates large activated carbon tanks is heavy, cumbersome, and time consuming to replace. Mar Cor Purification investigated carbon block technology as a solution to this on-going problem and as a result created the PTG-520® portable Carbon Filtration System. This compact, lightweight package will effectively remove harmful chlorine and chloramines prior to the RO system, just as activated carbon tanks would. However, the cost-effective PTG-520 carbon block technology eliminates the burden of lugging around weighty, unwieldy activated carbon tanks.


    The average activated carbon two-tank system can weigh upwards of more than 150 pounds. To effectively be transported, they must be placed on a cart. But this can be overwhelming and challenging to move a complete water treatment system weighing over 300 pounds, especially in a fast-paced environment, up and down hallway ramps, and on and off elevators. The PTG-520 system with carbon block technology solves this issue by weighing less than 50 pounds. The PTG-520 fits onto various portable RO carts, including all Mar Cor Purification models. This design allows carbon block filters to be attached to the cart, making the chlorine/chloramine an all-in-one removal system that is much easier to navigate. Just as important, the PTG-520 has been tested to meet carbon filtration usage in accordance to with today’s standards, ANSI/AAMI/ISO 23500, specifically Annex F & G for acute and home hemodialysis settings.


    Carbon filtration is an essential process prior to the RO system as it adsorbs both chlorines and chloramines commonly found in incoming feed water. This removal process is required first and foremost to ensure patient safety. In addition, if not done properly or efficiently, RO membrane(s) can be permanently damaged, costing both time and money. In a worst-case scenario test, the PTG-520 system using carbon block technology performed equivalently to standard activated carbon tanks. The test involved the filtration of hard-to-remove chloramines with a maximum level of 3.0 ppm concentration and 1.0 ppm ppm chlorine concentration (EPA water regulations’ recommended levels) as performance indicators. The test ran until a breakthrough occurred or when 30,800 gallons of water were consumed with a feed of 3 .0 ppm chloramine. 30,800 gallons represents an estimated one hemodialysis treatment per day (338 gallons) for 3 months or 13 weeks. Testing was done in 600 seconds on/600 seconds off cycle to simulate a challenging on-off scenario for the carbon blocks. In this worst-case, purposely challenging scenario, 30,800 gallons were reached without any chloramine or chlorine breakthrough.


    For the dialysis provider looking for a portable, more easily-maneuverable solution to heavy activated carbon tanks that is still competitive in cost-effectiveness, operational efficiency and does not compromise patient safety, the PTG-520 is an excellent alternative.
