To separate solids from liquids, nonwoven or woven fabrics out of animal or vegetable fibers are used, and synthetic fibers are now in use since several decades. In cross-flow filtration the filtrate is recuperated transversely to flow direction through a porous wall layer. In classic filtration, a filter cake is built up on filter surface and this cake reduce the flow of filtrate which will depend of the cake permeability. Often it needs such a cake structure build-up in order to obtain a clear filtrate. The filtration of slimy products such as proteins, polymeric carbohydrates or microorganisms was with the classical methods of filtration is quite costly or even impossible.
The characteristic feature of the cross-flow filtration is the high flow velocity over the filter surface, which avoid the build-up of a cake.
Cross flow filtration may be sufficient to achieve a filtration efficiency for separation of fine inorganic particles of a few micrometers in a low viscosity solvent.

The textile manufacturing industry encompasses many and diverse processes that rely heavily on the use of water, energy, chemicals, and other resources. Wet spinning, sizing, desizing, scouring, bleaching, mercerization, dyeing and printing are just a few. Monitoring and controlling the pH, TDS/Conductivity/Salt Concentration, ORP (REDOX), and Temperature of the aqueous solutions used in these processes conserves costly resources, controls quality, and reduces the amount of pollution that must be treated before discharge of effluent wastes. This can be done manually with handheld instruments or automatically with in-line monitor/controllers.

Wastewater from a textile facility contains a variety of dyes and organic chemicals from the manufacturing processes that are often difficult to treat. Spectral analysis is well suited for monitoring waste streams to identify problematic dyes prior to treatment. Continuous monitoring of effluent wastewater for BOD and COD helps to ensure effective treatment and quality of effluent to ensure regulatory goals are met prior to discharge.

All the industries including pharmaceutical, food&beverage, chemical, textil, paper & pulp, etc. require big quantities of water. The water used in any industrial process as for example heating, cooling or if it is going to be consumed directly in the process like in food & beverage industry should be purified and softened. Our range of pressure vessels can treat these effluents through sand, multimedia or activated carbon filters according to the needs.
