Abstract

Current industrial environmental regulations favor processes with Integrative Pollution Prevention and Control (IPPC). While several systems are regarded by different international directives as IPPC Best Available Techniques or Technologies (BAT), none of these systems are capable handling various pollutants of both gaseous and aquatic effluents. Additional hinder to a BAT-IPPC complete procedure are hazardous or uneconomical byproducts of the IPPC processes and significant auxiliary costs for consumables and energy. The current research and subsequent projects are aimed to the development of a Biological Integrative Pollution Prevention and Control (Bio-IPPC) system. Such system can be incorporated in various industrial processes, in a way that the byproduct is without hazardous potential and may be used as an economical raw material. The main initiative and heart of these systems is a micro-algae reactor, which is capable of treating various types of industrial pollutants both in the gaseous and aquatic phases. The algae nutrition is through thin-film circulation of the aquatic effluent and the reactor atmosphere is enriched by flue gases. The excessive algal biomass may be utilized for economic purposes starting with animal feedstock, through organic fertilizer and as industrial raw material for biofuels production or direct energy production. The first industrial project is a wastewater (WW) polishing stage to an industry zone WW treatment facility, which ensures high level effluent purification and assimilation of greenhouse gases, which are released during the WW bioremediation process. The second industrial application aims to treat aquatic and gaseous effluents from coal propelled power plants. The raw algal material from both projects although very different, is used for the development of new efficient scheme for bioethanol production. In summary, the system presented is an actual Bio-IPPC that can interactively treat several industrial effluents, while utilizing the algal biomass as a profitable raw material.

Highlights

While in the previous decade it was estimated that liquid fossil fuels will runout by the end of the new millennia’s first century [1,2], regulation in fossil resources production and new prospection and production methodologies indicates that fossil fuels will exist, together with other energy resources for generations to come [3]
The strategy enrolled in the current paper suggests to integrate the biomass cultivation system as a stage in an integrated waste treatment, known as Integrative Pollution Prevention and Control system (IPPC)
Biomass decomposition either in wastewater (WW) or surplus organic materials releases greenhouse gases (GHG), biomass processing can improve waste treatment processes and resolve such environmental hinders. This new strategy for the application of a Biological Integrative Pollution Prevention and Control system (Bio-IPPC) considers that nutrients and of organic matter in WW may be utilized as feedstock for aquatic biomass cultivation and the carbon dioxide produced in the bacterial stages of a treatment process may improve the vegetal biomass growth rate

Summary

Introduction

While in the previous decade it was estimated that liquid fossil fuels will runout by the end of the new millennia’s first century [1,2], regulation in fossil resources production and new prospection and production methodologies indicates that fossil fuels will exist, together with other energy resources for generations to come [3]. The strategy enrolled in the current paper suggests to integrate the biomass cultivation system as a stage in an integrated waste treatment, known as Integrative Pollution Prevention and Control system (IPPC).
