This BLOK is then strategically designed into the SILTBLOK 1200 chamber, so that all of the flow from the connected surface areas has to 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 . . offering an excellent sustainable solution without compromise.\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, offering an excellent sustainable solution without compromise.\u003c\/p\u003e\n\u003cp\u003eSILTBLOK SB1200 is designed for larger commercial developments, road \u0026amp; highways schemes, with surface water run off up to 3325m2 . Ideal for siting upstream of crate\/cellular attenuation systems, ponds, swales and irrigation systems.\u003c\/p\u003e\n\u003cp\u003eSILTBLOK removes particles from the discharged water through acting as a brake to disrupt the particle velocity and drop them out of suspension. For particles above 75µm the planks will generally remove around 95% particles on first use and improve towards 99.9% as the product is used and silts up. Below 75µm the planks will reduce the silts 50-70% depending on concentration.\u003c\/p\u003e\n\u003cp\u003eThe SILTBLOK SB1200 is supplied as standard, with prefitted HDPE twinwall access shaft, up to 3m depth. Alternatively the base unit can be built into a PCC chamber\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e1200 models are not supplied with access

SILTBLOK 1200 is an innovative and unique silt management product, designed and tested to filter out TSS (Total Suspended Solids), including silt to 30μm

porous block or (BLOK). This BLOK is then strategically designed into the SILTBLOK 1200 chamber, so that all of the flow from the connected surface areas has to 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 . . offering an excellent sustainable solution without compromise.\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.

Ideal for siting upstream of crate\/cellular attenuation systems, ponds, swales and irrigation systems.\u003c\/p\u003e\n\u003cp\u003eSILTBLOK removes particles from the discharged water through acting as a brake to disrupt the particle velocity and drop them out of suspension. For particles above 75µm the planks will generally remove around 95% particles on first use and improve towards 99.9% as the product is used and silts up. Below 75µm the planks will reduce the silts 50-70% depending on concentration.\u003c\/p\u003e\n\u003cp\u003eThe SILTBLOK SB1200 is supplied as standard, with prefitted HDPE twinwall access shaft, up to 3m depth.

Silt Guard SiltBlok 1200 Series for 150mm & 450mm pipework

£3,379.00
Maximum quantity available reached.

Our SILTBLOK 1200 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 1200 chamber, so that all of the flow from the connected surface areas has to 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 . . offering an excellent sustainable solution without compromise.

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, offering an excellent sustainable solution without compromise.

SILTBLOK SB1200 is designed for larger commercial developments, road & highways schemes, with surface water run off up to 3325m2 . Ideal for siting upstream of crate/cellular attenuation systems, ponds, swales and irrigation systems.

SILTBLOK removes particles from the discharged water through acting as a brake to disrupt the particle velocity and drop them out of suspension. For particles above 75µm the planks will generally remove around 95% particles on first use and improve towards 99.9% as the product is used and silts up. Below 75µm the planks will reduce the silts 50-70% depending on concentration.

The SILTBLOK SB1200 is supplied as standard, with prefitted HDPE twinwall access shaft, up to 3m depth. Alternatively the base unit can be built into a PCC chamber

1200 models are not supplied with access covers.

Mitigation

Event 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 run off volume.

The rainfall peak is based on 40mm/hr (once a year event)
