What does CDS stand for in stormwater?

What does CDS stand for in stormwater?

Patented continuous deflection separation (CDS) technology. system screens, separates and traps debris, sediment, and oil and grease from stormwater runoff.

What is a CDS manhole?

CDS® Using patented continuous deflective separation technology, the CDS system screens, separates and traps debris, sediment, and oil and grease from stormwater runoff. The indirect screening capability of the system allows for 100% removal of floatables and neutrally buoyant material without blinding.

What is CDS unit?

The CDS unit is a non-mechanical self-operating system and will function any time there is flow in the storm drainage system. The unit will continue to effectively capture pollutants in flows up to the design capacity even during extreme rainfall events when the design capacity may be exceeded.

How does a CDS unit work?

Continuous Deflective Separation (CDS) The system utilizes the natural motion of water to separate and trap sediments by indirect filtration. As the storm water flows through the system, a very fine screen deflects the pollutants, which are captured in a litter sump in the center of the system.

What do hydrodynamic separators do?

Hydrodynamic separators (HDS) are primarily used to remove sediment from stormwater by taking advantage of the force of gravity. Many HDS will also remove floatables such as oil and large items such as trash and debris. There are three main types of HDS: vault systems, swirl concentrators and inclined plate separators.

How does a stormceptor work?

Stormceptor creates a non-turbulent treatment environment below the insert platform within the system. The insert diverts water into the lower chamber, allowing free oils and debris to rise, and sediment to settle under relatively low velocity conditions.

What is CD water?

The CDS is a swirl concentrator hybrid technology that uses continuous deflective separation – a combination of swirl concentration and indirect screening to screen, separate and trap debris, sediment, and hydrocarbons from stormwater runoff.

What is an aqua swirl?

Aqua-Swirl® Stormwater Treatment System is a custom engineered, post-construction flow-through water quality device designed to remove coarse sediment, debris and free floating oil by utilizing hydrodynamic separation technology.

What does CDS stand for drugs?

Controlled Dangerous Substances
DEA Controlled Dangerous Substances (CDS) Many of the narcotics, synthetic steroids, depressants, and stimulants manufactured for legitimate medical use are subject to abuse and have, therefore, been brought under legal control.

What is a stormwater separator?

Stormwater separators are devices that use cyclonic separation to control water pollution. They are designed as flow-through structures with a settling or separation unit to remove sediment and other pollutants.

What are Stormceptors?

Stormceptor is an oil grit separator/hydrodynamic separator designed to protect waterways from hazardous material spills and stormwater pollution, including suspended sediment, free oils, floatables and other pollutants that attach to particles.

Are CdS precipitate?

Description: Cadmium sulfide precipitate. Cadmium sulfide (CdS) precipitate (bright yellow-orange) formed by adding 0.25 M solution of cadmium sulfate (CdSO4) drop by drop to 0.25 M solution of sodium sulfide (Na2S).
