Wood affected by woodworm. Signs of woodworm usually consist of holes in the wooden item, with live infestations showing powder (faeces), known as frass, around the holes.. The size of the holes varies, but they are typically 1 to 1.5 millimetres (5 ⁄ 128 to 1 ⁄ 16 in) in diameter for the most common household species, although they can be much larger in the case of the house longhorn beet
Identical to PEG treatment process but sucrose is used instead of PEG solution. The cells of the wood are replaced by sucrose, rather than water. Originally recommended as a low-cost method for treating waterlogged wood, sucrose treatments are inconsistent in how much shrinkage they prevent, especially for severely degraded wood. [12]
Fragment of a broomstick affected by woodworm. Woodboring beetles are commonly detected a few years after new construction. The lumber supply may have contained wood infected with beetle eggs or larvae, and since beetle life cycles can be one or more years, several years may pass before the presence of beetles becomes noticeable.
The shipworms, also called Teredo worms or simply Teredo (from Ancient Greek τερηδών (terēdṓn) 'wood-worm', via Latin terēdō), are marine bivalve molluscs in the family Teredinidae, a group of saltwater clams with long, soft, naked bodies.

The lower operating cost obtained with the submerged configuration along with the steady decrease in the membrane cost led to an exponential increase in membrane bioreactor plant installations from the mid-1990s. Since then, further improvements in membrane bioreactor design and operation have been introduced and incorporated into larger plants.
