In this paper, a reliable treatment process for olive mill wastewaters (OMWW) is proposed. In order to develop a more sustainable process with polyphenols recovery and water reuse, two treatment schemes have been simulated by using a process simulator (SuperPro Designer^®), depending on wastewater characteristics; the first applied for ‘biological’ effluents by using membrane technology (microfiltration MF, ultrafiltration UF, nanofiltration NF and reverse osmosis RO), the second for wastewaters containing pesticides, in which RO is replaced with an advanced oxidation process for pesticide degradation. The results of the process analysis showed that the final permeate is a treated water suitable for both disposal in aquatic receptors and for civil or agriculture reuse. Moreover, the results of a techno-economic analysis of the proposed processes is presented, carried out by means of a life cycle cost analysis, considering the mass and energy balances obtained from process analysis. The analysis showed that the first scenario is more economically feasible. In detail, the treatment cost (€/m³ of OMWW) was 253 and 292 €/m³ for the first and second case study, respectively. However, the second process scheme result is inappropriate if the wastewater to be treated does not come from biological olive processing.

本文提出了一种橄榄厂废水（OMWW）的可靠处理方法。为了发展与多酚回收和中水回用一个更加可持续的过程中，两个治疗方案进行了模拟使用过程模拟器（超强设计^®），取决于废水的特性；第一个应用膜技术（微滤MF，超滤UF，纳滤NF和反渗透RO）应用于“生物”废水，第二个用于含农药废水，其中RO被先进的氧化工艺取代以降解农药。过程分析的结果表明，最终的渗透液是经过处理的水，既适合在水生受体中处理，又适合民用或农业再利用。此外，通过对生命周期成本进行分析，并考虑了从过程分析中获得的质量和能量平衡，提出了对所提出的过程进行技术经济分析的结果。分析表明，第一种情况在经济上更可行。详细而言，治疗费用（€/ m第一个案例和第二个案例研究的OMWW ³分别为253和292€/ m ³。但是，如果要处理的废水不是来自生物橄榄加工，则第二种处理方案的结果是不合适的。
