WaterMark is the standard that is required by law for a qualified plumber in Australia to install any item on municipal town water. All products used under this certification will give you peace of mind knowing that your water filter complies with Australian plumbing codes. Our WaterMark filtration systems are hand assembled here in Australia and are batch tested to ensure quality and workmanship for your filtration products.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch4\u003e\u003cspan style=\"color: #3384e6; font-size: medium;\"\u003eUltraviolet Sanitation\u003c\/span\u003e\u003c\/h4\u003e\n\u003cp\u003e\u003cspan style=\"font-size: medium;\"\u003eUV Water Sanitation is by far the most important filtration process when it comes to rain water treatment. Rain water harbours bacteria of all types but is some cases much more harmful bacteria may be present in the tank. E-Coli is a common bacterium in tank water and is due mostly to Frogs in and around your tanks\/catchment. Ultraviolet sanitation works by breaking down the cell wall of a micro-organism allowing oxidation to occur which in turn prevents the bacteria from multiplying until it is finally eradicated. Ultraviolet filtration is a chemical-free solution to water sanitation creating no by products in the water.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch4\u003e\u003cspan style=\"color: #3384e6; font-size: medium;\"\u003eKit Contains\u003c\/span\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan style=\"font-size: medium;\"\u003eH7-90-AT - WaterMark Commercial UV System 48W | 1” Ports \u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-size: medium;\"\u003eH7-90-BRK (x2) - Pair of Aluminium Mounting Clamps + Screws \u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-size: medium;\"\u003eH7-90-Lamp - 436mm 4 Pin 48W High Output UV Lamp \u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-size: medium;\"\u003eH7-90-Thimble - 470mm Quartz Thimble 23mm*OD \u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-size: medium;\"\u003eH7-90-PS - Certified Ballast 42-105W Australian Plug + Earth Cable \u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-size: medium;\"\u003eGT7-2NSF-OR - NSF\/ANSI 42 Compliant O-Rings Suit 23mm*OD\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cspan style=\"color: #3384e6; font-size: medium;\"\u003eFeatures\u003c\/span\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan style=\"font-size: medium;\"\u003eCommercial Grade Electropolished 304 Stainless Steel Chamber \u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-size: medium;\"\u003eVisual \u0026amp; Audible Lamp Failure Alarm \u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-size: medium;\"\u003e1” BSP Threaded Male Connections \u0026amp; 3\/4\" BSP Internal Threads\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-size: medium;\"\u003eStrong Aluminium Mounting Brackets – Surrounds Chamber \u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-size: medium;\"\u003eHigh Intensity UV Lamps – Up to 105L\/min @ 30mJ\/cm²\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cspan style=\"color: #8324f7; font-size: medium;\"\u003eWater Pre-Treatment Specifications\u003c\/span\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan style=\"font-size: medium;\"\u003eHardness             \u0026lt; 120 mg\/L \u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-size: medium;\"\u003eTurbidity              \u0026lt; 1.0 NTU \u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-size: medium;\"\u003eIron                    \u0026lt; 0.3 mg\/L \u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-size: medium;\"\u003eManganese          \u0026lt; 0.05 mg\/L \u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-size: medium;\"\u003eTannins               \u0026lt; 0.1 mg\/L \u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-size: medium;\"\u003e Filtration            \u0026lt; 5uM Particulate Filtration\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cspan style=\"font-size: 12pt; color: #ff0000;\"\u003eUV System Maintenence Notes:\u003c\/span\u003e\u003c\/h3\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size: 12pt;\"\u003eUltraviolet systems are rated based on a dosage level of UV-C radiation into the water (mJ\/cm²), with 30mJ\/cm² being the standard level of disinfection and a minimum dose of 40mJ\/cm² required to comply with Australian Drinking Water Guidelines.
