This book serves as a comprehensive summary of water reclamation technologies and practices for minimizing liquid discharge for a broad range of industries. It is of use to practitioners, consultants, management, and research and development professionals who want a timely update on the technologies in use and on those technologies on the horizon to provide the highest rates of water recovery in industrial practice. The industrial sectors covered include oil and gas (unconventional oil and gas and produced and petroleum refining water), pharmaceutical, textile, automotive, manufacturing, energy, and food and beverage. The book covers a much broader perspective than North America, including technology development and sustainable applications within the water-scarce yet growing regions of Central and South America, Asia, and the Middle East.

Polymers are excellent flocculants and are critical for use as a solids conditioner prior to thickening and dewatering equipment. Applying polymer prior to a thickening or dewatering process, or “conditioning”, is often a requirement for the thickening or dewatering equipment to successfully operate. This operator fact sheet takes readers through the basics of polymers used in thickening and dewatering processes. You will learn about different types of polymer products, how to calculate polymer dose, appropriate handling and storage of polymer products, and equipment and processes relating to make-down and activation. This information can help operators make informed decisions to save money on polymer use in water resource recovery facilities (WRRFs).

For workers in the water sector, inherent workplace conditions expose them to daily potential for serious injury. Working in the confined spaces under city streets often comes with awkward postures, incessant vibrations, extreme temperatures, and hazardous gases that can injure. For workers dealing with chemicals or risking exposure to known viruses, bacteria, protozoa, and parasites, the risks become even more complicated. Physical inspection of tanks, pipes, and reservoirs — regardless of provided safety precautions — often require workers to step into environments that carry these risks as well as potential for catastrophic physical traumas.As a result, safety is a necessity. While strict adherence to departmental safety protocols and the proper deployment of personal protective equipment can reduce injuries, the only way to truly eliminate these types of injuries is to keep workers from entering those dangerous environments in the first place.However, such a simple proposition, proves more difficult in real-world application. How does a utility actually inspect and repair small-diameter pipes, investigate sediment buildup in holding tanks, or evaluate a collapsed pipe or sewer tunnel without deploying personnel into that very dangerous situation?Historically, these projects often called for entire system segments to be taken off-line, tanks to be drained, or heavy equipment to dig up entire city blocks. Now, the burgeoning drone industry is bringing numerous purpose-built solutions to the aid of water and wastewater agencies looking for safer, more efficient, and more affordable options.

The prime objective of this work was to identify the major sources of internal heat generation and locations within the water recovery facility that provide the most potential for heat dispersion to the atmosphere. A facility-wide thermal energy model applied to each unit process was developed, calibrated and validated at two water recovery facilities....
