  • The wastewater treatment of the food industry

    The wastewater treatment is a process which is used to recycle the wastewater into an effluent that can be reused again. This treatment helps in removing all the impurities from the water. Many industries are involved in this type of treatment to make use of water and not to waste it. Due to the scarcity of water, this type of water recycle is necessary. Many foods and beverage processing ...

  • Combined ultrafiltration-electrodeionization technique for production of high purity water

    Electrodeionization (EDI) is the most common method to produce high purity water used for boiler feed water, microelectronic, and pharmaceutical industries. Commonly, EDI is combined with reverse osmosis (RO) to meet the requirement of EDI feed water, with hardness less than 1 ppm. However, RO requires a relatively high operating pressure and ultrafiltration (UF) as pretreatment which results ...

  • Degasification of boiler feed water with Liqui-Cel® membrane contactors

    Proper treatment of boiler feed water is an important part of operating and maintaining a boiler system. As steam is produced, dissolved solids become concentrated and form deposits inside the boiler. This leads to poor heat transfer and reduces the efficiency of the boiler. Dissolved gasses such as oxygen and carbon dioxide will react with the metals in the boiler system and lead to boiler ...

  • Real Time TOC Analysis in Steam and Condensate

    Executive Summary Steam in petro/chemical plants could be contaminated with hydrocarbons (TOC = Total Organic Carbons) from various sources. In any case this is a sign for defects in the process, whether it they occur in the heat exchanger, the blow down vessel, the condensate recovery or other parts of the system. Conventional solutions to monitor such contaminations use TOC- analyzers that ...

  • Energy and exergy analyses of a supercritical power plant

    Energy and exergy efficiencies of a supercritical power plant have been studied in this paper. The effect of ambient weather condition was considered on the condenser pressure. It was shown that high ambient temperature has more adverse effect on the exergy efficiency than the energy efficiency. As ambient temperature increases, the exergy efficiency of the boiler, condenser, heaters and feed ...

  • VSEP improves industrial boiler performance and reduces blowdown frequency by a factor of ten

    In the steam boiler industry, high purity feed water is required to ensure proper operation of steam generation systems. High purity feed water reduces the use of boiler chemicals due to less frequent blowdown requirements (reducing blowdown frequency by as much as a factor of 10). Lower blowdown frequency also results in lower fuel costs. Scale buildup is reduced due to a smaller concentration ...
