Advanced catch basin filter captures multiple pollutants

Catch basin inserts, such as the Ultra-Drain Guard, are effective in most situations. However, if the drains are located in known “hot spots” where concentrated contamination is more likely, a filter with greater capability may be necessary. The Ultra-HydroKleen is considered a “true filter” by the EPA because it utilises up to three different filters to remove pollutants from stormwater before it exits into the stormwater system. The Ultra-HydroKleen is the only catch basin filter that allows users to mix and match filter media according to their specific needs.

Sorb 44 — Used to remove oil and other hydrocarbons.

Phos Filter — Excellent for removal of phosphorus.

Activated Carbon — Excellent “polishing media”. Helps remove certain chemicals, hydrocarbons, and odors.

Heavy Metal Removal — Custom filter media blend helps remove zinc, lead, copper, and other harmful, heavy metals.

Other types of media available for custom applications.


  • Removes hydrocarbons, heavy metals, sediments and other organics from stormwater and industrial runoff.
  • Exceeds 80% sediment removal efficiency. Patented filtration system allows different filter media to be used together to remove targeted pollutants.
  • Choose a mix of filters to removes hydrocarbons / oil, chemicals, odour, phosphorus and heavy metals from water flow (must be ordered separately).
  • A by-pass system prevents flooding or ponding during high-flow storm events.
  • Excellent post-construction control for drains that are more susceptible to large concentrations of contaminants (“Hot Spots”).
  • Units available for round or square catch basin grates. Custom sizes available.

1. How many filters will fit in an Ultra-HydroKleen?

The Ultra-HydroKleen is designed to fit up to three filters.

 2. If I order different types of filters, how do I know what order they should be arranged?

The order will depend on the concentration of the pollutants in the water and may require some experimentation to get the best results. Typically, if an activated carbon filter is used, it will be the last filter media before the water exits the Ultra-HydroKleen as it is a “polishing” media.

3. Is there a way to take a post-treatment sample with the Ultra-HydroKleen?

Yes, a sampling option is available that will allow “post-treatment” samples to be taken. The sampling option is Product CHU9876 and MUST be ordered with the Ultra-HydroKleen (it cannot be installed as a retrofit).

4. What are the dimensions of the body of the Ultra-HydroKleen (the green shell)?

The body of the Ultra-HydroKleen is 182mm L x 381mm W x 431mm H.

5. Can an Ultra-Hydrokleen be used inside a round catch basin?

Yes, but the diameter of the drain opening within the ledge that the grate sits (X2) will need to be at least 660mm.This is because the rectangular bottom portion of the Hydrokleen is 182mm x381mm and the widest part of the shell would be approximately 614mm” wide. A 660mm diameter would allow the unit to fit comfortably within the catch basin.

6. How often should I change the filters?

This will depend on the location of the unit and will vary for each Ultra-HydroKleen. We recommend an inspection after the first rainfall to get an idea of what the pollutant load is for that particular drain. Periodic inspections and water testing will help determine the efficiency of each filter and when replacements are necessary.

7. What’s the easiest way to remove captured sediment from the Ultra-HydroKleen?

Sediment, silt, sand, and dirt can be scooped out of the HydroKleen’s chamber or, for complete removal, the entire Ultra-HydroKleen can be removed from the catch basin and hosed out.

8. What is the ordering process like for the Ultra-HydroKleen?

Initially, the process is just like any other product, it is ordered through one of our distributors. But once we receive that order we will coordinate with your distributor to get more information on the catch basin that the Ultra-HydroKleen will be installed in. We will need to get the  measurement instructions and filter media selection forms completed and returned to us. Because of the customization of this product, there is a lead time involved. Once all the information is provided we will be able to provide you with an estimated lead time.
