The early stages of stormwater management focused on the removal of sand, sediment, dirt, trash, and oil from runoff. But heavy metals have taken over the spotlight. And for good reason, because of their high degree of toxicity, many of these elements rank among the priority metals that are of public health significance.
Standard geotextiles and filter fabric won’t remove heavy metals. So we use six pounds of a custom blend of filter media to remove them from stormwater flow.
NOTE: Unless otherwise noted, all listed product measurements are L x W x H, outside dimensions, and for a single unit where quantity is more than one.

By simply dropping a small tablet into each storm drain, you can increase the oil absorbing and removal effectiveness of your Ultra-Drain Guard. Ultra-Archaea are oil-eating microbes that will consume any hydrocarbons in the Ultra-Drain Guard as well as inside the catch basin. Click here for more information.
Please check with your local authorities on the proper disposal. Since it is likely filled with heavy metals and hydrocarbons, a standard landfill may not be appropriate.
We want to make sure that ALL of the water goes through the filter media in the body of the Ultra-Drain Guard. In most cases, the geotextile material we use with our other Ultra-Drain Guards is sufficient to remove many of the pollutants. But it (the geotextile material) is not designed to filter or capture heavy metals.

Yes. While other Ultra-Drain Guards have flow rates in excess of 700 GPM, the heavy metal model has a flow rate of 275 GPM. This is necessary for the filter media to have enough time to effectively remove the heavy metals.
Yes, the Ultra-Drain Guard, Heavy Metal Model absorbs up to .23 gallons.
Yes, the needle-punched geotextile material used, can absorb synthetic oils.
The Ultra-Drain Guard, Heavy Metal Model can remove/contain up to 190 grams of heavy metals.
The Ultra-Hydrokleen does an excellent job of removing heavy metals as does the Ultra-Filter Sock. You can also check out the Path to the Perfect Product to see what other products might be a good option.
