{"product_id":"birm_263_2-5_cuft","title":"13\" x 54\" Birm Commercial Filter, Autotrol 263-740 Digital Time Controller 1.0 m³\/hr","description":"\u003cp\u003eBirm is a relatively inexpensive material which can be used for iron and manganese removal by oxidation. It requires a pH of 7 or more for Iron removal and pH 8 for manganese removal (it uses dissolved oxygen in the water to oxidise the metal). As it acts a catalyst it is not consumed so Birm doesn’t requirere generating or topping up. Birm also has the advantage of acting as a filter, removing turbidity. If the pH of the water is too low pH correction may be required. Media life expectancy is 2 to 3 years.\u003c\/p\u003e\n\u003ch3\u003eSpecification\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth scope=\"col\"\u003eValve\u003c\/th\u003e\n\u003cth scope=\"col\"\u003eSize\u003c\/th\u003e\n\u003cth scope=\"col\"\u003eVolume\u003c\/th\u003e\n\u003cth scope=\"col\"\u003eMax Service Flow\u003c\/th\u003e\n\u003cth scope=\"col\"\u003eBackwash Flow\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eAutotrol 263\u003c\/td\u003e\n\u003ctd\u003e10x54\u003c\/td\u003e\n\u003ctd\u003e1.5 Cuft\u003c\/td\u003e\n\u003ctd\u003e0.6m³\/hr\u003c\/td\u003e\n\u003ctd\u003e1.1m³\/hr\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAutotrol 263\u003c\/td\u003e\n\u003ctd\u003e12x52\u003c\/td\u003e\n\u003ctd\u003e2 Cuft\u003c\/td\u003e\n\u003ctd\u003e0.9m³\/hr\u003c\/td\u003e\n\u003ctd\u003e1.8m³\/hr\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAutotrol 263\u003c\/td\u003e\n\u003ctd\u003e13x54\u003c\/td\u003e\n\u003ctd\u003e2.5 Cuft\u003c\/td\u003e\n\u003ctd\u003e1m³\/hr\u003c\/td\u003e\n\u003ctd\u003e2m³\/hr\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAutotrol 263\u003c\/td\u003e\n\u003ctd\u003e14x65\u003c\/td\u003e\n\u003ctd\u003e3 Cuft\u003c\/td\u003e\n\u003ctd\u003e1.2m³\/hr\u003c\/td\u003e\n\u003ctd\u003e2.3m³\/hr\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAutotrol 263\u003c\/td\u003e\n\u003ctd\u003e16x65\u003c\/td\u003e\n\u003ctd\u003e3.5 Cuft\u003c\/td\u003e\n\u003ctd\u003e1.6m³\/hr\u003c\/td\u003e\n\u003ctd\u003e3.4m³\/hr\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAutotrol 263\u003c\/td\u003e\n\u003ctd\u003e18x65\u003c\/td\u003e\n\u003ctd\u003e5 Cuft\u003c\/td\u003e\n\u003ctd\u003e2m³\/hr\u003c\/td\u003e\n\u003ctd\u003e3.9m³\/hr\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIron Removal Criteria\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003epH: 7 - 8.5 ( High pH conditions may cause the formulation of colloidal iron which is very difficult to filter out)\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eAlkalinity: greater than twice the combined sulphate and chloride\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eOrganic matter: \u0026lt;4-5 ppm\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eDissolved oxygen: at least 15% of the iron or manganese content less than 0.5% chlorine, no H2S, oil or polyphosphates\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eMax.
