Harnessing the Joule-Thomson effect for treating wastewater with high salinity

By Paul Grad |

A thermal-membrane process system, based on the Joule-Thompson effect (JTE) for treating wastewater with high salinity or with a high-level of inorganic contents has been developed by Thermosift Engineering Pvt. Ltd. (Asaripallam, Tamil Nadu, India; www.thermosift.com). The system operates at relatively low pressure and temperature compared with the conventional thermal-based separation processes. Other advantages are a very high water recovery at a minimum energy consumption, small footprint and minimum capital cost compared with the conventional thermal separation systems, says the company. Called TS-30, the system is capable of producing up to 30 L of water per square meter of membrane. The company has also developed the Stomat vapor-transfer membrane for high strength industrial effluent treatment, desalination and heat- and mass-transfer processes. The TS-30 system uses the microporous Stomat membrane as a JTE “throttling device,” which functions as the porous plug or the expansion valve. This JTE process helps increase the mass transfer due to heat loss and the company’s product design helps to recover the heat, which in turn improves the thermal efficiency of the entire TS-30 system. Recently, the company successfully…

PTA production: Lowering OPEX without compromising on quality

A paper that looks at how the earlier PTA production method involving a multi-stage process with pressure and atmospheric centrifuges and a re-slurry tank can be replaced with one stand-alone device – the rotary pressure filter (RPF).
