Wastewater Treatment and Recycling Management

Scarcity of resources and sustainability goals are driving major global changes to the way water authorities are operating. Sustainable treatment of wastewater and biosolids management practices can play a major role in allowing authorities to meet current cost-effective treatment and community expectations. This can be achieved through:

• Biosolids management to enable beneficial use of final product

• N-E-W (Nutrients - Energy - Water) paradigm - potential to provide high quality resource recovery, as well as generation of power and heat to offset the energy requirement of wastewater treatment

• Odor management (and corrosion control) for assets

• Treatment of wastewater to enable re-use - this might involve non-potable direct, indirect reuse or irrigation of agricultural or municipal land holdings, and dependent on site, and proximity and effluent quality.

GHD has a long history of delivering performance reviews, augmentation, planning, and design of new wastewater treatment plants globally, and providing innovative, cost-effective and practical solutions.  We work closely with clients to investigate, plan, design, and oversee the construction and start-up of facilities that treat wastewater. We also collaborate with technical associations, universities, research organizations, and regulatory agencies to maintain industry leadership and active engagement in the latest developments in wastewater treatment, odor control, and biosolids management.

Our team has first-hand experience with state-of-the-art technologies, such as MBR's, RO, thermal hydrolysis, and advanced anaerobic digestion, and trial programs for water resource recovery and energy generation.

We have extensive experience and capabilities in all aspects of wastewater management and strategic development and implementation, planning, and implementation including:

• Alternatives analysis, concept / process design
• Construction phase engineering services
• Detailed design
• Environmental, water quality management review and program development
• Feasibility studies, incorporating investigations, modelling, mass balances, risk, and life cycle assessment
• Greenhouse gas assessment and reporting
• Odor, air pollution control assessment and design
• Operational troubleshooting, maintenance, and commissioning
• Regulatory assistance
• Residuals management, including stabilization and dewatering, hazardous wastes
• Treatment technology design, incorporating physical / chemical, biological treatment, natural process, membranes, disinfection
• Water cycle management, including water use minimization and recycling of effluent for municipal and industrial

GHD has the skills to tailor solutions that will achieve the best outcome for our clients. We help to define a strategy for wastewater, shifting the focus toward resource recovery and sustainable environmental management, for lasting community benefit.
