In our blog post titled “Construction Site Runoff? You have options!,” we introduced HaloKlear Floc Socks. HaloKlear Floc Socks from Dober are sturdy, connected, fabric pouches containing an all-natural flocculant that dissolves slowly as moving water passes over them, creating dense flocs – with great shear strength and low water content – that settle out quickly. Solids are efficiently removed from the water, allowing your crew to focus on their work – instead of on dirty water. In addition, the HaloKlear Floc Socks are extremely flexible, and can be used in active, passive, and semi-passive treatment environments.

This post will outline HaloKlear Floc Sock use for Passive Treatment of Turbid Water Utilizing a Loose Material Dual Product System with Matting and Wattles.

WHAT IS ITS PURPOSE?

To clean construction storm water from a pond using a passive system prior to discharge into a regulated water body.

WHERE AND HOW IS IT COMMONLY USED? (SEE FIGURE)

  • On a stream of construction run off to treat the water prior to discharge.

WHEN SHOULD IT BE INSTALLED?

  • Before construction activities begin
  • While construction activities are occurring
  • To treat water stored on site
  • After project completion to clean dirty water stored on site
  • As pre-treatment for secondary treatment
  • When discharging into a non-high quality water body

WHEN SHOULD IT NOT BE INSTALLED?

  • When precise dosing of treatment chemicals is required
  • When discharging into a high quality water body

WHAT NEEDS TO BE INSPECTED?

  • Is the natural flocculant material in good condition?
  • What is the condition of the matting and wattles?
  • Is the water exiting the system of sufficient clarity?
  • Does the residual water test show any remaining natural flocculant in the effluent water?

WHAT MAINTENANCE ACTIVITIES CAN BE EXPECTED?

  • Addition of natural flocculant when/if necessary
  • Cleaning or replacement of matting and/or wattles

NOTES

  • Natural flocculants in general should not be directly released into civic storm water systems or natural watercourses.
  • Discharging water through vegetated areas or additional BMP’s can further reduce turbidity.
  • Natural flocculants will completely degrade with enzymatic action.
  • Dose rate of chemical is dependent on flow rate and volume of water.
