Effect of environmental regulation on the profitability of sustainable water use in the agro-food industry

Dairy wastewater treatment using an electrochemical method: Experimental and statistical study

“…The pH was measured using a pH meter (METTLER-TOLEDO 320) which was calibrated with the standard buffers at room temperature. In each run, 250 cm 3 were carried out at room temperature (25 °C ± 2 °C) and atmospheric pressure. DC power source was turned off and the reaction was stopped when the reaction time was found.…”

“…The wastewaters obtained from the dairy industries are characterized by large amounts of organic materials, suspended solids, oils, salts and fats [3]. The effluent depends on the amounts of processed milk, type of products and equipments, production method, system management and washing mechanism [4].…”

Buffer recycling in downstream processing of biologics

“…Currently, the manufacture of 1 g of a biopharmaceutical agent requires approximately 65 liters of water for injection (wfi), using expensive, high quality water costing s2.00 per liter. In the food [1], steel [2], textile [3], and electronic industries, strategies have been developed to reduce buffer/water consumption by as much as 90%. Consider a scenario projecting the manufacture of 10 000 kg of biopharmaceutical proteins.…”

“…Horizon 2020, the EU research and development program for all biotechnological processes, requires that the impact on the environment of industrial processes must be clearly demonstrated. Other measures include specific taxes on water consumption or providing incentives in the form of tax reductions when environmentally friendly technologies are used [1].…”

Processo de tratamento biológico e físico-químico combinados visando o reúso de esgoto sanitário

“…A indústria é muito diversificada, heterogênea e caracterizada por alto consumo de água devido diferentes tipos de processos e unidades operacionais nos quais a água é envolvida (SÁNCHEZ et al, 2011;VALH et al, 2011). Como já mencionado anteriormente, no Brasil, cerca de 18% do volume total captado de recursos hídricos para os usos consuntivos são destinados para fins industriais e agroindústrias.…”
