14/10/2014 - Fórum leva a São Paulo palestrantes internacionais e apresenta soluções para a potabilização da água a partir de efluentes
Evento promove palestras e debates sobre processos de reaproveitamento de efluentes para fins potáveis em períodos de escassez
Em meio à atual crise no Sistema Cantareira e à crescente necessidade de novos processos para a gestão dos recursos hídricos, a cidade de São Paulo recebe, nos dias 15 e 16 de outubro, o I Fórum Técnico Internacional "Reúso Direto e Indireto de Efluentes para Potabilização", na Faculdade de Saúde Pública da Universidade de São Paulo (FSP/USP). O evento reúne especialistas nacionais e internacionais para apresentar e discutir as principais alternativas e a viabilidade do reaproveitamento de efluentes para produção de água potável no Brasil.
Sete palestrantes internacionais participam do Fórum e expõem experiências de reaproveitamento de água em países como Estados Unidos, México e Namíbia, sendo este último o país onde a potabilização da água a partir de efluentes é um dos métodos de reaproveitamento mais bem-sucedidos do mundo.
Além das experiências internacionais, o evento conta com a participação de especialistas brasileiros como o professor Victor Wünsch Filho, diretor da Faculdade de Saúde Pública da USP, o professor Pedro Mancuso, também da FSP/USP, e Ivanildo Hespanhol, diretor do Centro Internacional de Referência em Reúso de Água e professor da Escola Politécnica da USP. Otávio Okano, presidente da Cetesb, Daniel R. Fink, Procurador de Justiça do Ministério Público do Estado de São Paulo e Alceu Bittencourt, presidente da Associação Brasileira de Engenharia Sanitária e Ambiental (ABES-SP), também participam das palestras e debates.
Três painéis compõem o Fórum, que se inicia com a “Disponibilidade Hídrica das Regiões Metropolitanas Brasileiras e Plano de Segurança da Água”. O primeiro painel conta com palestras de Gesner de Oliveira, economista e ex-presidente da Sabesp, Alceu Bittencourt, presidente da ABES-SP e a engenheira sanitarista Roseana Maria Garcia Lopes de Souza.
O segundo painel, com o tema “Experiências Internacionais”, leva ao evento as apresentações de especialistas estrangeiros. Além dos casos positivos de potabilização de água em outros países, este painel promove o debate sobre as questões regulatórias decorrentes deste processo e tem como um dos destaques a apresentação sobre a experiência de reutilização de água na Califórnia.
No Brasil, o reúso de efluentes já é amplamente utilizado para fins industriais. O projeto Aquapolo, que abastece o Polo Petroquímico de Capuava, por meio do reaproveitamento dos efluentes domésticos (esgoto) da ETE (Estação de Tratamento de Esgotos) ABC da Sabesp, é exemplo disso. O último painel do evento, “Aspectos Técnico-Operacionais e Legais para Implantação do Reúso para Potabilização”, discute a viabilidade deste método de potabilização de água para uso potável no Brasil.
Com debate entre os professores Pedro Mancuso, Ivanildo Hespanhol, Otávio Okano e Daniel R. Fink, o evento se encerra com a discussão sobre as barreiras nas leis brasileiras, os impedimentos e receios da população e os processos viáveis para o País, principalmente em períodos de escassez de água como a atual crise em São Paulo.
O I Fórum Técnico Internacional "Reúso Direto e Indireto de Efluentes para Potabilização” é realizado pelo portal Tratamento de Água em parceria com o Centro de Apoio à Faculdade de Saúde Pública da Universidade de São Paulo (CEAP/FSP).

Presentation Abstract: Direct and Indirect Potable Reuse: The utilization of alternative water sources like reclaimed municipal wastewater is one of the most promising options for a sustainable integrated water management. Among the various beneficial uses of reclaimed wastewater the managed Direct and Indirect Potable Reuse (DIPR) receives growing attention. The current state of the DIPR is presented in this article, advantages and implementing feasibility is highlighted. The required water quality is discussed. There is a need of research on the long time health effects of emerging pathogens and trace organic constituents. Regulatory requirements for DIPR are established only in some countries; therefore regulation development is needed. Reclamation technology, options and examples of existing systems are provided. Today, technically proven water reclamation processes can provide water of almost any desired quality. Natural environmental barrier and multiple barriers in the purification process are considered for DIPR. Identification of treatment alternatives and a comparison of the potential health risks are essential steps for DIPR implementing. Research is required to develop novel treatment systems able to ensure the removal of micro-contaminants of health concern.
Michael Robert Markus: General manager of the Orange County Water District. With more than 35 years of experience, Mike is well known for his expertise in large project implementation and water resource management.
During his 26-year career at the District, Mike was responsible for managing the implementation of the $480 million Groundwater Replenishment System program. This project is the largest planned indirect potable reuse project in the world and has won many awards including the 2008 Stockholm Industry Water Award, 2009 ASCE Outstanding Civil Engineering Achievement Award, 2014 U.S. Water Prize and 2014 Lee Kuan Yew Prize.
Presentation Abstract 1: Groundwater Replenishment: Orange County Water District's Experience
The Groundwater Replenishment System (GWRS) is the largest planned indirect potable reuse project in the world. It currently produces 265,000 cubic meters per day (m3/d) of highly purified recycled water that is used for groundwater recharge and also for direct injection into coastal wells, which form a barrier to protect the groundwater basin from seawater intrusion. The GWRS takes clarified secondary effluent and uses advanced treatment consisting of microfiltration (MF), reverse osmosis (RO) and ultraviolet light/advanced oxidation (UV/AOP) to produce water that is of near distilled water quality. This new source of water is drought-proof and provides enough water for nearly 600,000 people while also lessening the amount of imported water supplies.
The project has been so successful that the District is currently expanding the facility and will be producing an additional 113,500 m3/d in February 2015.
Presentation Abstract 2: The Role of Monitoring in Public Health Protection
Water quality monitoring has played key role in the Orange County Water District’s (OCWD) operation of potable reuse facilities, beginning with the Water Factory 21 (WF-21) project in the 1970s and continuing today with the Groundwater Replenishment System (GWRS). These monitoring programs are analogous to those applied to conventional drinking water sources, but take into account the unique features of potable reuse to protect against acute microbial, acute chemical, and chronic chemical risks. Monitoring begins with source control programs in the sewershed and continues throughout the multi-barrier treatment process. While traditional laboratory testing remains at the core of OCWD’s GWRS water quality monitoring program, the use of online real-time monitoring to verify the treatment effectiveness has increased greatly since the days of WF-21. The need for online sensors to reliably detect real-time treatment process failure will only grow with the increasing interest in direct potable reuse projects lacking environmental buffers or significant retention time prior to distribution.

Presentation Abstract: Potable Reuse in Windhoek - Namibia
Namibia is the most arid country on Southern Africa and more than 80 % of this area consists of desert or semi-desert. The annual rainfall in Windhoek is approximately 370 mm. The potential surface evaporation rate is in the range of 3,000 mm/a. The nearest river, the Okavango, is aprox. 700 Km from Windhoek. Therefore, the city is water stressed and several severe droughts have made direct potable reuse vital for its development. The Windhoek experience shows that treated domestic sewage can be successfully used for potable reclamation. The multiple barrier approach employed guarantees reclaimed water of a quality that constantly meets all the required drinking water standards. Aproximately 30 % of the potable water supply consists of reclaimed water. Therefore, this source is an essential part of the integrated water resource management and has contributed greatly to the social and economic development of the city.

Presentation Abstract: Status of Direct Potable Reuse - Initiatives in Texas
With a population expected to double within the next 50 years and a commitment to supporting its growing economy, water supply has become a priority issue in the state of Texas. Water utilities in Texas have been leaders in the implementation of water reuse projects as part of the state’s water supply portfolio. Planned projects implementing indirect potable water reuse have been in place since the 1980’s. More recently, due to extended dry periods and lack of other economical water supply options in the western portion of the state, direct potable reuse has been implemented or is being planned at several utilities. This presentation will provide a brief background on water supply issues in Texas and discuss the evolution of potable reuse implementation in the state. Case study examples of several direct potable reuse projects will be provided.

Presentation Abstract: Direct Potable Reuse - A Progress Report
Population growth; urbanization, especially along coastal regions; and climate change are resulting in stressed public water supplies and development of new water supplies for metropolitan areas is becoming increasingly difficult, if not impossible. As a consequence, existing water supplies must go further. One approach for achieving this objective is by increased water reuse, particularly in supplementing municipal water supplies. Although non-potable water reuse offers many opportunities, the quantities of water recycled are limited or seasonal and the cost per unit volume used associated with the separate piping and storage systems for reclaimed water is prohibitive. The solution to the problems of limited and seasonal demand and distribution and storage costs is to implement direct potable reuse (DPR) of purified water, in which purified municipal wastewater water directly into municipal water supply systems. The issues associated with DPR, the progress towards implementation, and the outlook for the future are explored.

Presentation Abstract: Monitoring for Reliability and Process Control of Potable Reuse Applications
Potable reuse can be either indirect or direct, but for any potable reuse application, it is imperative that the reclaimed water is subjected to advanced treatment to remove both traditional and emerging chemical and microbial contaminants. It is also imperative that any advanced treatment failure be detected in real-time, to prevent contamination of potable water supplies. Therefore we have evaluated the ability of on-line sensors, to detect chemical or microbial contaminants in water destined to become a potable water source. Our vision was to advance smart water reuse systems that are self-monitoring and self-healing, thereby gaining public trust through demonstrated reliability and security. The University of Arizona Real-Time Sensor Laboratory has already been built and will be housed in the new Water and Energy Sustainable Technology (WEST) Center.
This dedicated facility for on-line monitoring and process control is one of the most advanced laboratories of its kind worldwide, with an established track record of real-time detection and destruction of contaminants. Advanced treatment technologies for reclaimed water include: UV ± H2O2; ozone ± H2O2; reverse osmosis; microfiltration; and granular activated carbon. Real-time sensors in the lab include on-line sensors for general water quality parameters as well as organic and microbial contaminants.

Presentation Abstract: California Regulatory Setting for Potable Reuse and Reservoir Augmentation
California has had indirect potable reuse projects via groundwater recharge since 1962. There are seven operating projects in the state and several more proposed. In addition, there is increasing interest in direct potable reuse, and the California Department of Public Health (CDPH) recently initiated an independent advisory panel to assist them in the development of needed criteria. This presentation will address the status, regulatory controls, and issues associated with indirect potable reuse via groundwater recharge (for injection and surface spreading) and surface water augmentation as well as a possible regulatory scheme for direct potable reuse. The treatment process, water quality, monitoring, response retention time, and other requirements in the CDPH groundwater recharge regulations will be discussed. The relationship between the potable reuse regulations and the California Safe Drinking Water Act also will be presented.
