The B400 Series maintains the safety of tanks and vessels under extreme pressure from external fire sources. The B400 also facilitates access to the tank for inspection and cleaning purposes. Additional Vacuum relief is also available on applicable sizes.

Anaerobic digestion is one of the most effective methods of treating biosolids from municipal and industrial wastewater. It is an ideal method in meeting strict environmental regulations in highly urban areas. During the anaerobic process, soluble organics are converted to methane (CH4) and carbon dioxide (CO2). This occurs in a two-step process and in closed vessels, called digesters or in lagoons or covered ponds.

Biogas utilisation and collection is a vital component of the anaerobic digestion process. This saturated gas is quite dangerous to people, as well as being corrosive to equipment and pipes. Therefore it is of paramount importance to manage biogas properly in order to maintain a protected environment.
