Odour Control Tank Covers
Relinea’s new structurally robust and lightweight GRP Tank Covers are designed to provide effective odour control solutions for various
applications in waste water treatment plants such as sludge tanks & settlement tanks.
Relinea’s GRP Tank Covers can be used for:
- Odour control
- Eliminating algae growth
- Fall protection for personnel
- Protection from ingress of water or other debris
Our bespoke GRP odour control Tank Cover range are manufactured using a high chemical resistant resin system and can span from 1m - 20m. They are
individually designed and manufactured to customer specification under ISO 9001:2008 Quality Management Certification.
We fabricate, supply, deliver and install your bespoke GRP tank covers across Ireland and the UK, including Northern Ireland, England, Scotland and Wales.
Circular Self-Supporting GRP Tank Covers
Relinea’s lightweight and self-supporting conical (circular) shaped GRP Tank Covers are designed to fit onto either concrete or steel tanks up to a 20m diameter.
Our standard conical tank cover range has a 20° pitch and consists of identical one piece segments that are lightweight and easily transported. Each segment
comes with external flanges that are bolted together around a central hub.
Our GRP Circular Tank Covers are manufactured using a high grade chemical resistant resin that is available in an array of RAL or BS4800 colour codes to
suit client specification.
Relinea’s self-supporting conical GRP Tank Covers are generally designed to suit a 0.75 kN/m2 uniform loading in accordance
with WUMES 8.05 and BS EN 1991-1 Standards. However, we have the capability to adapt our design to suit higher loadings
to suit client requirements.
Conical tank covers are suitable were maintenance access only is required. If regular access is required a low profile Beam and Infill Tank Cover can be supplied.
Beam and Infill GRP Tank Covers
Relinea can offer both circular and rectangular GRP Tank Covers that are of a low profile and can be designed for pedestrian access.
Our Beam and Infill Tank Covers are suitable for tanks up to 10m wide. The system is modular and can be built directly onto the structure
which avoids the need for emptying and cleaning the tanks as access is not required.
Our Beam and Infill GRP Tank Covers have a smooth moulded surface and incorporate composite beams. If regular pedestrian access is required, the tank cover
surface can be gritted with our integral Aluminium Oxide Grit which provides exceptional slip resistance in very wet or oily conditions.
Bespoke GRP Covers
Relinea can provide design solutions for a custom built GRP Cover to meet both specific client requirements and site requirements.
Such bespoke covers can be used for applications such as safety fall protection - as per the image above, demonstrating a bespoke tank cover constructed
using GRP mesh grating and GRP bespoke beams.
How can GRP Tank Covers perform better than steel tank covers?
Steel can corrode and will deform easily under impact. Tank covers manufactured from steel are very susceptible to chemical attack in the highly
corrosive environment found underneath an odour control tank cover within a waste water treatment plant. In addition, if hit by a heavy
object steel may be subject to permanent deformation and may need to be replaced.
GRP tank covers are highly resistant to corrosion due to the use of high grade resins that are suitable for the environment that the cover
will be exposed to. This ensures that the tank structure remains structurally sound throughout its life and avoids unobserved corrosion to the
underside of the cover that can potentially cause contamination from rust etc.
GRP performs exceptionally well under impact and would in many instances avoid the need for replacement. However, if the damage is considerable
GRP the tank panels can be easily repaired in situ.
How do GRP Tank Covers perform against chemicals?
On Waste Water Treatment & Sewerage Treatment Plants chemical attack is a genuine concern and can cause significant damage to plant and equipment.
Where odour control tank covers are required, such as over sludge and treatment tanks, the environment can be chemically aggressive resulting
from the damp conditions and attack from Hydrogen Sulphide (H2S), both of which can have a serious effect on steel.
The use of GRP tank covers can solve many of the issues associated with corrosion on sewage treatment plants due to its high chemical resistant properties. Tank covers manufactured in GRP can offer an excellent long term and durable solution to the traditional steel system.
Relinea can offer a range of resins that are specifically selected to fit the chemical environment its products will be exposed to. This combined with
excellent design ensures that we will deliver a tank cover that is structurally strong throughout its life cycle and further avoid unobserved corrosion
to the underside of the tank cover that can potentially cause cover failure.
