Flame-resistant paper for radio wave absorber members includes 40 to 70% by mass of pulp; 5 to 50% by mass of aluminum hydroxide powder; and 3 to 15% by mass of a flame retardant consisting of a polyborate, wherein the flame retardant consisting of a polyborate is contained in an amount of 7 to 25% by mass relative to the amount of the pulp.

The present disclosure provides compositions and methods for treating volatile fatty acids and bacteria capable of producing volatile fatty acids. The compositions can convert acid-producing bacteria environments to nitrate-reducing bacteria environments. The compositions and methods can lower the amount of acid-producing bacteria present in the environment and thereby reduce the amount of volatile fatty acids present in the environment. The control agent may also inhibit the growth of acid-producing bacteria and volatile fatty acid concentrations. The compositions and methods can be used with any aqueous industrial system.
