Chemtech International Inc. is an exclusive distributor of UltraTech International Inc., the industry-leading manufacturer of stormwater management and erosion control products. All UltraTech International Inc. products are designed to meet the New Stormwater Management Regulations of the EPA’s Clean Water Act, to help businesses maximize operational efficiency while protecting the environment.

What is stormwater?

Stormwater is rainwater or melted snow that runs off streets, lawns, and other sites, which is typically absorbed into the ground and ultimately flows into streams and rivers. Impervious surfaces such as pavement and roofs, however, prevent stormwater to naturally soak into the ground. The water instead runs rapidly into storm drains, sewer systems, and drainage ditches, which can cause a wide range of problems, including downstream flooding, stream bank erosion, sewer overflows, infrastructure damage, contaminated streams, rivers and coastal water.

Stormwater Management Products

UltraTech International Inc. offers a comprehensive line of stormwater management products to effectively prevent various types of pollutants and contaminants, including hydrocarbons, dirt and sediment, from entering waterstorm systems, storm drains, catch basins and curb inlets.

Cost-Efficient Solutions

Advanced erosion control products from UltraTech International Inc. are cost-efficient solutions to prevent erosion and minimize sediment runoff found in stormwater. All UltraTech International Inc. dewatering bags, silt dike barrier systems, and gravel bags are designed to effectively capture trapped sediment and oil and to prevent erosion and infrastructure damage.

Ultra HydroKleen

Advanced catch basin filter captures multiple pollutants, also provides sampling capability 

  • This BMP removes hydrocarbons, heavy metals, sediment, 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 remove hydrocarbons/oil, chemicals, odor, phosphorus, and heavy metals from water flow.
  • By-pass system prevents flooding or ponding during highflow 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.*
  • Considered a “true filter” with separate chambers for sediment removal and filters.
  • Verified by the EPA’s ETV program.
  • Helps comply with NPDES, 40 CFR 122.26 (1999) when used as Best Management Practice in Stormwater Pollution Prevention Plans.

Mix and match filter media depending on your specific needs. HydroKleen is the only catch basin filter that allows
you to use more than one type of filter media.*

Sorb 44 — Used to remove oil and other hydrocarbons.

Phos Filter — Excellent for removal of phosphorous.

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.

Sampling Option — Convenient and effective means to obtain samples of the “post-treatment” effluent from the Ultra-HydroKleen to comply with monitoring and testing requirements.

sampling Ultra HydroKleen
  • Sampling Option provides standard HydroKleen with modifications to allow Universal Sampler (pg. 64) to pull “post-treatment” water samples from below the unit’s filters.
  • Take real-time samples during storm events.
  • Access area stays closed until a sample is desired.
  • Simple sampling — No need to remove the Ultra-HydroKleen to take a sample (in many cases, even the grate can remain in place). Simply slide open the sampling port and insert the Universal Sampler.

* Note: Ultra-HydroKleen units are custom made to fit each individual catch basin. The final pricing is based on the configuration of the frame (Flat or Recessed) and number of required Filter Media (2 or 3).
