China Organic waste treatment to Energy Equipment/

waste water digester tank for biogas project


Welcome to ShandongBetter New Energy Co., Ltd

BETTER is a manufacturer devoted to Bolted Steel Tank, Double Membrane Gas Storage Cabinet, Full auto control system, Biogas Pre-treatment System and other equipments used in biogas and wastewater treatment industries.

Our BETTER brand has 30 years experience in production management, 19 national patents and passes ISO 9001 quality certification.

We are not only the Bolted Tank/Gas Holder manufacturer in China, but also a professional biogas and wastewater plant solution supplier.

ECPC Bolted Steel StorageTank /Biogas Digester

Our ECPC bolted steel storage tank is the best suitable container used for Biogas digester /anaerobic reactor tank which  is assembled by special steel plates, dedicated sealing materials, self-locking boltsetc. Afterpretreatment both inside and outside steelplate are coated wiith electro-coating and powder-coating. The double layer protective coats enable the bolted tank to possess excellent anti-corrosion property and strong resistance to wearing and collision with service life up to 30 years.

The steel plates lapped mutually by using self-locking bolts connection and dedicated sealing material, it’s available to swiftand low power installation.


Step One of Anti-corrosion: E-coating

E-Coating/E-coated/Electrocoating is an immersion painting process in which charged paint particles are attracted to an oppositely charged metallic surface. As the paint is deposited, it forms a coating, which insulates the metal from the surrounding charged solution. The e-coat process continues until the coating reaches the desired thickness.

Electrocoating immersion ensures 100 percent coverage of complex parts, as well as uniform thickness with no runs or sags. This in turn ensures superior corrosion protection. Consistent, controlled application nearly eliminates the need for manual touchups. At the same time, E-coat systemenhances paint circulation without clumping, settling or foaming.

Step Two of Anti-corrosion: P-coating

Powder coating is a finishing process in which a coating is applied electrostatically to a surface as a free-floating, dry powder before heat is used to finalize the coating.

The benefits of the process of powder coating are numerous. First, powder coating results in a thick, dense finish on metal products which can be more durable and longer lasting than conventional painting. Second, powder coating is typically a one coat finish so the process can be quite quick and easy. Third, powder coating can include multiple custom finishing colors and textures as the powders which are sprayed onto the item can be expertly manipulated. Fourth, powder coating is an environmentally safe finishing process because it produces few volatile organic compounds. Finally, powder coating creates the most even finished surfaces (horizontal and vertical surfaces) because the powder is sprayed and heated across without drips or application traces.


Why choose our ECPC Bolted Steel Storage Tank for Biogas Digester?

1.      High-efficiency and high-precision maching

2.      Plate surface is smoothness, does not distort

3.      There is no limit to steel plate thickness in terms of ECPC process.

So far, there is plate thickness limitfor LIPP tank and Enamel tank, For large tank construction, the steel plate must reach a certain thickness to satisfy strength requirement.

4.      Full coverage anti-corrosion processed: bolt hole, flanges, pipe fitting, ladder, platform, accessories.

5.      Double layer anti-corrosion for both inside and outside of the steel plate

6.      Strong resistance to shock, flexible for bent/collision, coating not effected during transportation and installation.

7.      Color is diverse for customized

8.      Recyclable for re-ECPC

9.      Poison free and pollution free of ECPC process

10.  A high resistance to aggressive materials and corrosive liquids (PH: 1~14)

11.  Highly resistant to atmospheric corrosion and UV light

12.  High durability and extended life usage (More over 30 years)

13.  Easy maintenance and cleaning

14.  Operational duty time considerably reduced

15.  Short manufacturing times

16.  Expandability and the ability to relocate

17.  High cost effective, minimal maintenance expense
