SiltSoxx RH Rice Hull Filter Sock
The newest, lightest filter sock for your BMP toolbox.
Filled with rice hull filter media and encased in our Original, Durable+ netting, SiltSoxx RH is lighter than a compost filter sock but heavier than a straw wattle – making it easier to handle and install, with the superior filtering performance that MKB products are known for.
Independent testing by TRI Environmental shows that rice hulls form an excellent high-flow, high sediment retention 3-dimensional filtering matrix when used in E&S tubular products. Rice hulls are a domestic by-product that comes from rice farming within the U.S. in California, Arkansas, the Gulf Coast, and in the Mississippi River Delta region.
Use SiltSoxx RH just like a compost filter sock or straw wattle for standard sediment control applications like perimeters, slope interruption, and other hard-to-reach project sites – no trenching is required.
If you’re looking for a more sustainable option, SiltSoxx RH is also available in our Natural+ biodegradable netting. This 100% biodegradable product eliminates the need for field removal and disposal, allowing you to leave the rice hull media on-site as a beneficial soil amendment, while also eliminating expensive labor costs and landfill tipping fees.
With SiltSoxx RH, you’ll save money, time, and achieve superior filtering performance. Ready to try SiltSoxx RH on your next sediment control project? Contact MKB Company today to find a distributor.
