What is SDD3

The SDD3 by NEXT Stormwater Solutions is a hydrodynamic oil and grit separator that utilizes both gravitational and centrifugal forces to capture and retain suspended sediments, floating particles and oils from Stormwater runoff.

The SDD3 unique design ensures optimal storm water treatment during light and heavy rainfall events.

Advantages

Can be installed in series or in parallel because of its bypass system

Strong and durable structure made in reinforced concrete able to support Cl-625, H-25 ans HS-20 charges

The installation and the maintenance are easy to do from the surface

Double vortex to maximize the performance

Internal aluminium components (5052-H32) have high mechanical properties and excellent corrosion resistance

ETV certified

Performance

The SDD3 storm water treatment system has one of the best load rates in the industry, which translates into superior performance.
The SDD3 system effectively removes sediment and oils from stormwater.

When sizing the SDD3, it is important to take into account the standards applicable to hydrodynamic separators, the treatment flow rate and the provincial and municipal regulatory control criteria targeted by each project.
This is also necessary when you compare the performance of SDD3 to other technologies.

The efficiency of a sediment separator system such as SDD3 varies depending on the loading rate and the particle size used for its evaluation. Our system guarantees optimal rainwater treatment for a wide range of flow rates.

How it works

The water to be treated enters the unit through the main line (series installation) or through a bypass line (parallel installation)
The water is directed to the two vortices where the centrifugal forces, generated by the circular movement of the water, separate the suspended particles and the oils
The particles are decanted and collected at the bottom of the unit
The oils are transported (by gravitational ascent) and stored separately under the oblique plate
The treated water is finally directed to the outlet pipe.

	</div><h5>How does the SDD3 unit work?</h5><p>Our system uses centrifugal and gravitational forces to remove sediment and oil. The SDD3 uses a double vortex system which guarantees superior performance.</p><h5 tabindex="0" role="tab" aria-controls="ui-id-2" aria-selected="false" aria-expanded="false">What materials are use to make up your system?</h5><p>The interior sediment removal system is made of 5052-H38 aluminum, an alloy with high mechanical properties not subject to heat treatment with good resistance to fatigue. In addition, it has excellent resistance to corrosion even in salt water. The exterior structure is made of reinforced concrete and complies with manhole manufacturing standards.</p><h5>Is it possible to install the pipes at an angle?</h5><p>Yes, it is possible to install an angled pipe.</p><h5>What is the maximum pipe diameter for each unit model?</h5><p>The maximum pipe diameter for each unit model varies by model. Usually it is the same as a standard gaze from. Indeed, our treatment system is installed inside a standard reinforced concrete manhole.</p><h5>Is it complicated to install your product?</h5><p>No, our product is installed exactly like a standard manhole. The interior part is preinstalled at the factory. The rest of the installation can be done on site.</p><h5>Is an anti-flotation slab required under your units in situations of high water table?</h5><p>No anti-flotation slab is unnecessary.</p><h5>What are the weights of your units?</h5><p>The weight of our units varies from model to model. On the other hand, those which are installed in a standard manhole (SDD-900 to SDD- 2400) have the same weight with a few small differences as a standard manhole. For larger models, the weight varies depending on the project.</p><h5>What are the certifications of the SDD3?</h5><p>VTE</p><h5>What is the maximum flow that can flow through the processing unit?</h5><p>The maximum flow that can circulate in our system is the same as that which can circulate in the rainwater network. Our system has been designed to be installed “In-Line” in all situations.</p><h5>What is the effect on the piezometric line?</h5><p>The effect on the piezometric line is negligible when compared to that of a standard manhole with the same alignment of the pipes</p><h5>Has it resuspended the oil / sediment during "extraordinary" events such as back-ups and if the unit submerges?.</h5><p>There is no problem that arises if there is repression or the unit is overwhelmed. In addition, there is no resuspension of oil or sediment already stored.</p><h5>Is cleaning / maintenance complicated?</h5><p>Cleaning / maintaining the SDD processing unit is very easy. Everything can be done from the surface of the ground. The cleaning is carried out using vacuum trucks.</p><h5>Where do your products come from?</h5><p>Our products were designed in Quebec, however they are manufactured by our partners according to the geographical position.</p><h5>How can we get technical support?</h5><p>When you purchase one of our products, we provide technical support and after-sales service by phone, email and video conferencing.</p><h1> </h1>[/stal_core_accordion_child]"]
