STINK-SHIELD®

ANTI-SMELL SHIELD / VALVES FOR UNITARY NETWORKS

The city centers of our cities are invaded at certain times of the year by the smells coming from the pavement drains. This phenomenon is due to: • the presence of an unitary evacuation network;• the drying out of the siphons installed in the storm water manholes;• atmospheric pressure variations that generate air flows between the inside and the outside of

the networks. To stop these smells, NORHAM has developed an innovative process: the STINK-SHIELD® and STINK-SHIELD® VERTICAL anti-smell valves.

AREA OF USE• Rainwater chute, rain boxes.

PRINCIPLE OF OPERATION

IN RAIN WEATHER: NORMAL EVACUATION OF WATER

During rainfall, the rain water level rises to the level of the STINK-SHIELD® VERTICAL anti-smell valve.

Under the effect of the thrust of water, the membrane opens and allow the rainwater to drain to the collector.

1. Very low flow allows evacuation through the anti-smell valve. 2. When the drains are fully loaded,the 3 membranes of the STINK-SHIELD® VERTICAL

are totally open.

PER DRY PERIOD: STOPS ODORS

In dry season, the anti-smell valve STINK-SHIELD® VERTICAL is in closed position.

The set of membranes makes the seal, stops the rise of smells that remain confined inside the collector.

Closed flap: bad smells are confined in the

collector.

PERFORMANCE

Tests were carried out by the CSTB (Scientific and Technical Center of Building), in order to establish and validate the performance of the anti-smell valve STINK-SHIELD® VERTICAL.

HYDRAULIC CAPACITY: THROUGHPUT ≥ 60 l/s

A 700 mm x 700 mm large drain grid has a maximum throughput of 60 l/s. The STINK-SHIELD® VERTICAL must be able to evacuate a flow rate at least equivalent to the drain grid. The valve has superior hydraulic capacity* when the water level in the manhole exceeds 0,8 mWC .

Curve from several tests validated by the CSTB to check the repeatability. Flow test carried out by the CSTB.Report N° CAPE-AT 16-215

SMELL SEALING

In order to qualify its smell-sealing performance, the STINK-SHIELD® VERTICAL is subjected to a through-flow such as it could be during a stormy period (see hydraulic capacity test). In addition, the tests are performed with water loaded with leaves, paper, cigarette butts.

A dry period is then simulated and the flow of air passing between the downstream and the upstream* of the STINK-SHIELD® VERTICAL is measured. If a flow is found, this corresponds to a leak.

The STINK-SHIELD® VERTICAL only allows up to 4 % of the airflow.

*Downstream = unitary network collector; upstream = rain water manhole. // Leak test performed by the CSTB. // Report N° CAPE-AT 16-216. // Technical file relating to the tests carried out on request and on www.norham.fr.

INSTALLATIONThe STINK-SHIELD® VERTICAL adapts to all types of pipes and manhole configurations and is installed: • at the entrance of the rain water evacuation network;• in abutment, it is held in place thanks to its

expansion collar. It can be removed at any time for inspection or maintenance.

For installation on a drain outlet manifold that is not perpendicular to the wall, the stop ring must be cut (predefined zone) and the expansion clamp installed.

STINK-SHIELD®

In dry weather, the elbows (siphons) that equip the drains of our streets are no longer effective because they are no longer immersed.To relay the anti-smell function when the drain is dried, NORHAM has designed an innovative process: the STINK-SHIELD® anti-smell valve.

TECHNICAL DATA• Body: recyclable elastomer type SEBS;• clamp: stainless steel AISI 304;• DN: 200 mm.

Installation on a PVC elbow (not included).

OPERATING PRINCIPLE

IN RAINY WEATHER: NORMAL EVACUATION OF WATER

• During rainfall, the rainwater manhole rises to the level of STINK-SHIELD®;• under the effect of the thrust of water, the two main ears of the STINK-SHIELD® open and allow

the rainwater to drain to the collector.

BY DRY PERIOD: STOP SMELLS

During evaporation, the water level decreases in the manhole.• When the water level is above the STINK-SHIELD®, the secondary ear

open to allow the residual water to drain out of the pipe. The elbow still acts as a siphon;

• as soon as the water level is below the elbow, the STINK-SHIELD® is in the closed position. It prevents bad smells from the collector, rising to the surface and vitiating the ambient air.

STINK-SHIELD®

ANTI-SMELL SHIELD / VALVES FOR UNITARY NETWORKS

Tests have been carried out by the CSTB (Scientific and Technical Building Center) to establish and validate the performance of the STINK-SHIELD® anti-smell valve.

FLOW THROUGH ≥ 60 l/s

A large drain grid 700 mm x 700 mm has a maximum through flow of 60 l/s. The valve must allow to evacuate a flow at least equivalent.

Tests show that it meets this criterion in every respect.

The STINK-SHIELD® even has a higher capacity when the water level in the rainwater manhole exceeds 1,2 mCE.

The hydraulic capacity* of the «elbow + STINK-SHIELD®» assembly is equivalent to that of a DN 160 mm pipe.

Throughflow tests carried out by the report N° EN-CAPE14.170 C-V1 downloadable on www.norham.fr.

*Hydraulic capacity = throughout.

SMELL SEALING

In order to qualify the performance of the STINK-SHIELD® to make the network watertight, it was first subjected to a through flow as it could be during a stormy period. The tests were performed with water loaded with leaves, paper, cigarette butts.

A dry period is then simulated and the flow rate of air passing between the downstream and the upstream* of the STINK-SHIELD® is measured. If a flow is found, this corresponds to a leak.STINK-SHIELD® only allows a maximum of 1 % of the air flow.

Leak tests carried out by the report N° EN-CAPE14.021 C-V0 downloadable on www.norham.fr.

*Downstream = rainwater network collector; upstream = rainwater manhole.
