Center Enamel Portable Assembly Biogas Anaerobic Digester Tank for Sewage Water Disposal ISO

China Center Enamel Portable Assembly Biogas Anaerobic Digester Tank for Sewage Water Disposal

Roofs / Covers for Glass Fused to Steel Tanks

1. Externally Supported Roof (Glass Fused to Steel Roof):

BioEnergy Storage Solutions include the best cover options for digester applications. The gas zone of a digester is the most corrosive area and requires appropriate design.

Along with this corrosiveness, there are many other factors (environmental, mixer loads, vacuums, pressure, ancillary equipment loads, etc.) that need to be considered in cover selection. Center Enamel can design and engineer the right solution from the multiple roofs types according to client’s request.

The most common roof design is with a smooth internal roof surface and without rafters. Used when moderate to high pressure or vacuum design limits are anticipated. It is also preferred when there are heavy load conditions expected from mixers and/or other ancillary equipment is installed in the cover.

Application: potable water storage cover, bulk storage cover, anaerobic digester cover, anaerobic fermentation tank cover,

Benefits:

Super gas-tightness

Corrosion resistance and abrasion

Heat preservation

Easy installation

2. Aluminum Deck Roof (Highly recommended for potable water storage)

Application: potable/drinking water storage, etc.

Advantages:

•very low cost

•Easy installation

•Light weight

•High strength

•Durable

•Nice appearance

•Anti oxidation

•Store least amount of heat and get cool very quickly

3. Glass Fiber Reinforced Polyester Roof (GRP Roof )

Advantages: water storage, Desalination Plants,Air Purification Systems ,Food and Beverage Industry, Petrochemical Industry Plants, Industrial Sewage Treatment, etc.

Application:

•Light weight, 1/4 weight of DI and 1/10 weight of concrete

•Corrosion Free

•Easy for handling and installation

•Proven resistance to acidic environmental in water and sewage system

•Low maintenance cost

•Fast installation with reduced numbers of joints due to pipe length up to 12 meters

•Better Hydraulic performance than steel, DI, and concrete

•Variety of joint system (Flange, Tee, Elbow, Reducer and spools)

•Long effective service life

4. Double Membrane Roof

Application: Anaerobic digestion, biogas, biofuel, biomass

Benefits:

This option is well established in the anaerobic market, offering a low cost option to a sealed, gas tight roof.

Designed to operate in applications with low to moderate gas pressures where there is not a design requirement for a fixed steel or aluminum cover. Multiple layers and optional center support structures are utilized depending on design considerations.

The outer membrane remains permanently inflated while the inner membrane inflates and deflates in proportion to biogas production therefore making them a suitable option for pressurized applications.
