This BLOK is then strategically designed into the SILTBLOK 500 chamber, so that all of the flow from the connected surface areas pass through the BLOK itself.\u003c\/p\u003e\n\u003cp\u003eThe BLOK then separates\/filters out the Silt \/TSS within the flow, allowing only cleansed water to pass through its matrix. The SILT BLOK will not blind, deteriorate or corrode.\u003c\/p\u003e\n\u003cp\u003eSILTBLOK SB500 is designed for housing or commercial developments, with a surface water run off of up to 1200m2 . Ideal for siting upstream of crate\/cellular attenuation systems, ponds, swales and irrigation systems.\u003c\/p\u003e\n\u003cp\u003eAs detailed opposite the BLOK has a silt basket attached. The basket catches any silt and debris entering the unit and can be simply removed for emptying and cleaning. The basket capacity is 17.5kg, which is the average annual silt storage for around 4 average semi -detached properties.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSB500 models are not supplied with access covers. \u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003cspan style=\"text-decoration: underline;\" data-mce-style=\"text-decoration: underline;\"\u003e\u003cstrong\u003eOptional Accessories\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"text-decoration: underline;\" data-mce-style=\"text-decoration: underline;\"\u003e\u003c\/span\u003e\u003ca href=\"https:\/\/www.freeflush.co.uk\/products\/accesso-chamber-access-covers?variant=40064747241559\"\u003eAccess Cover\u003c\/a\u003e - 500ACC\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"text-decoration: underline;\"\u003e\u003cstrong\u003ePipework\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eInlet pipework – from 150mm \u0026amp; 225mm\u003c\/li\u003e\n\u003cli\u003eOutlet pipework – from 150mm \u0026amp; 225mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan style=\"text-decoration: underline;\" data-mce-style=\"text-decoration: underline;\"\u003e\u003cstrong\u003eDepths Available\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e1480mm\u003c\/li\u003e\n\u003cli\u003e1990mm\u003c\/li\u003e\n\u003cli\u003e2400mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan style=\"text-decoration: underline;\" data-mce-style=\"text-decoration: underline;\"\u003e\u003c\/span\u003e\u003c\/strong\u003e\u003cspan data-mce-fragment=\"1\"\u003e\u003cspan style=\"text-decoration: underline;\" data-mce-style=\"text-decoration: underline;\"\u003e\u003cstrong\u003eMitigation\u003c\/strong\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eEvent mean concentration (EMC) refers to a flow-weighted average concentration in the whole process of a rainfall-runoff event, defined as the total pollution load mass divided by the total runoff volume\u003c\/p\u003e\n\u003cstyle type=\"text\/css\"\u003e\u003c!--\ntd {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}\n--\u003e\u003c\/style\u003e\n\u003ctable xmlns=\"http:\/\/www.w3.org\/1999\/xhtml\" cellspacing=\"0\" cellpadding=\"0\" dir=\"ltr\" border=\"1\"\u003e\n\u003ccolgroup\u003e \u003ccol width=\"112\"\u003e \u003ccol width=\"133\"\u003e \u003ccol width=\"115\"\u003e \u003c\/colgroup\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\" data-sheets-value='{\"1\":2,\"2\":\"EMC \\n(Event Mean Concentration Values)\"}' data-mce-style=\"text-align: center;\"\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eEMC \u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003e(Event Mean Concentration Values)\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\" data-sheets-value='{\"1\":2,\"2\":\"TSS \\n(Total Suspended Solids \\n(mg\/l) or PPM)\"}' data-mce-style=\"text-align: center;\"\u003e\n\u003cstrong\u003eTSS \u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003e(Total Suspended Solids \u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003e(mg\/l) or PPM)\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\" data-sheets-value='{\"1\":2,\"2\":\"Commercial Areas\"}' data-mce-style=\"text-align: center;\"\u003eCommercial Areas\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\" data-sheets-value='{\"1\":2,\"2\":\"7.8 -

Silt Guard SiltBlok 500 Series for 150mm & 225mm pipework

£839.00
Maximum quantity available reached.

Our New SILTBLOK 500 is an innovative and unique silt management product, designed and tested to filter out TSS (Total Suspended Solids), including silt to 30μm (0.03mm).

The SILTBLOK’s core technology is extremely eco friendly, using a 100% recycled thermoplastic material, formed into a macro porous/micro porous block or (BLOK). This BLOK is then strategically designed into the SILTBLOK 500 chamber, so that all of the flow from the connected surface areas pass through the BLOK itself.

The BLOK then separates/filters out the Silt /TSS within the flow, allowing only cleansed water to pass through its matrix. The SILT BLOK will not blind, deteriorate or corrode.

SILTBLOK SB500 is designed for housing or commercial developments, with a surface water run off of up to 1200m2 . Ideal for siting upstream of crate/cellular attenuation systems, ponds, swales and irrigation systems.

As detailed opposite the BLOK has a silt basket attached. The basket catches any silt and debris entering the unit and can be simply removed for emptying and cleaning. The basket capacity is 17.5kg, which is the average annual silt storage for around 4 average semi -detached properties.

SB500 models are not supplied with access covers.
