They can also be used in projects such as wastewater reuse and concentration.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eNSF\/ANSI Standard 61 Certified\u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003eAll PRM Reverse Osmosis elements are officially NSF 61 Certified for use with potable water.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eAdditionally, these membranes are manufactured without pre-chlorination, enabling chemical cleaning across a wide pH tolerance range (pH 1–13) and delivering consistent long-term rejection performance.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eSpecifications:\u003c\/h3\u003e\n\u003ctable border=\"0\" dir=\"ltr\" cellpadding=\"0\" cellspacing=\"0\" xmlns=\"http:\/\/www.w3.org\/1999\/xhtml\"\u003e\n\u003ccolgroup\u003e \u003ccol width=\"auto\"\u003e \u003ccol width=\"auto\"\u003e \u003c\/colgroup\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eBW8040-400LF\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStable salt rejection rate(%)\u003c\/td\u003e\n\u003ctd\u003e99.5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInlet grille thickness(mil)\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e32\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAverage flow GPD(m³\/d)\u003c\/td\u003e\n\u003ctd\u003e11000 (41.6)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMembrane area ft²(m)\u003c\/td\u003e\n\u003ctd\u003e400 (37.2)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax.
