Fluid treatment assemblies comprising a plurality of adjustable tensioning rod assemblies comprising tensioning rods having a tensioning nut and a locking nut threadably attached to the tensioning rods, and methods of adjusting the tension on the assemblies, are provided.

Fluid treatment assembly and method of use

Fluid treatment assemblies may include first and second end pieces, at least one fluid treatment unit positioned between the first and second end pieces, and a retainer extending between the first and second end pieces and arranged to press the fluid treatment unit(s) and the first and second end pieces together. Each of the end pieces is formed from a nonmetallic material and has a flexural modulus of at least about 1.5&#xd7;10psi.

Fluid treatment assemblies

A fluid treatment assembly comprises one or more cross flow fluid treatment units positioned between opposite end pieces. The fluid treatment unit includes a permeable fluid treatment medium having a feed side and a permeate side. The fluid treatment assembly further comprises a feed inlet and feed passage, a permeate outlet and a permeate passage, and a retentate outlet and a retentate passage. The feed passage directs feed fluid from the feed inlet to the permeable medium and tangentially along the feed side of the permeable medium. The permeate passage directs permeate from the permeate side of the permeable medium to the permeate outlet. The retentate passage directs retentate from the feed side of the permeable medium to the retentate outlet. A flow restrictor is positioned in the retentate passage.

Fluid treatment assemblies, manifolds for fluid treatment assemblies, and methods for treating fluids

This invention relates to filtration assemblies and methods of installing filtration units in filtration assemblies. Filtration assemblies may include first and second end pieces, at least one filtration unit between the first and second end pieces, and at least one alignment rod arrangement. The alignment rod arrangement may extend between the end pieces and align the filtration units and the end pieces.

Filtration assemblies and methods of installing filtration units in filtration assemblies

This invention relates to filtration manifolds, filtration assemblies, methods of channeling permeate, and filtration units. Filtration assemblies may include filtration units and filtration manifolds having isolated permeate collection passages. Permeate may be channeled through the isolated permeate collection passages of the filtration manifold during filtration and then output from the manifold.
