Durable treatment tank and clarifier cover

The high quality of the materials used to manufacture the covers, combined with innovative production technology makes Wiefferinks covers unique. they have a long lifespan and will provide many years of low maintainance service.

The WWTP Silocover is ideal for covering all type of tanks and clarifiers, as bridges, service openings, piping connections can be designed into these covers. Covers can be made for all shapes of tanks; no matter if they are round, square or rectangular.  Wiefferink has much experience in the WWT sector, in other countries that Wiefferink serve, many have regulations in place to curb air pollution emissions from sewage treatment tanks, and the covering of silos is the norm rather than the exception.

Conforms with environmental and statistical directives

Reducing CO2 emissions is becoming a priority for every organisation, covering your silos is an easy way to meet carbon reduction targets. An additional benefit of covering your clarifier in an urban highly populated setting is odour control, enabling you to be a better neighbour and reduce complaints. Our WWTP Silocovers satisfy both environmental legislation and construction related directives, every cover is designed in accordance with the location it will be fitted in and comes with an individual statistical calculation report.

Absorbs external forces

The WWTP Silocover is manufactured from heavy polyester fabric with a synthetic coating on both sides. As a result, it can withstand sewage sludge and other aggressive substances and protects against many years of extreme weather conditions. The WWTP Silocover is equipped with an unique system of edge pipes and tension sets, stainless steel strips which transfer the forces from the cone to the silo circumference. It is also possible to adjust the tension later when required. Inspection openings provide access to the tank for cleaning or maintenance. The WWTP Silocover is available in a gas-tight and a non-gas-tight version.

Safe and fast installation of the cover

The WWTP Silocover is manufactured in our factory in a clean and conditioned environment. Cover installations are carried out by our team of experienced engineers who are certified to work on safety sensitive sites, such as waste water treatment plants. Installation time is kept to a minimum due to prefabrication of the cover in the factory, in most cases completed in a matter of days.

Rotating cover

Many treatment tanks are equipped with rotating skimmer arms. In close cooperation with engineer’s, Wiefferink has developed a rotating cover for these types of tanks. These covers provide effective coverage of the tank enabling easy access for service and maintenance.

Maintenance and lifespan

The WWTP Silocover requires very little maintenance; after a large snowfall the snow must be removed, and the Silocover must be kept at the right tension. Normal life time expectation is at least 15 years.
