Key West Resort Utilities Maximizes Reuse And Nutrient Recovery
Water scarcity poses unique challenges to KW Resort Utilities Corp. (KWRU), the utility firm that provides wastewater management, wastewater recovery, and wastewater treatment in the region. KWRU began operation in the late 1960s and has worked hard over the decades to keep up with wastewater needs as population and tourism have boomed, spurred by land reclamation and development.

Reassessing The Value Of Water Reuse In Process Efficiency
In many industrial applications, water is not part of the final product but an important process facilitator — for cooling, cleaning, etc. Like energy, it can quickly become a major expense and, therefore, an important target for cost control. As potable water supplies tighten or become increasingly expensive, reuse is becoming a more attractive alternative. Here is some of the information needed to evaluate the opportunities it offers.

DO Or Die — Dealing With Aeration Basin Oxygen Deficiencies
Managing the treatment of wastewater — especially industry-generated wastewater that can elevate dissolved oxygen (DO) demands far beyond those of municipal/residential applications — is hard enough. Trying to do so during upset conditions is enough to put any water treatment professional on edge. Here are several preventive and remedial options to keep in mind before or after DO readings go haywire.

The 3 Main Reasons To Use Carbon Dioxide For pH Control
Finding ways to improve everyday processes in more efficient and productive ways is an important goal for most companies. Many water and wastewater treatment facilities use sulfuric acid when pH reduction is needed, but face safety and process risks as a result. As an alternative to sulfuric acid, carbon dioxide (CO2) offers several benefits.

Accurate Sludge Conditioning For Good Dewatering Results
Where should I put the sludge? There is a consensus among wastewater plant operators and other industry groups that the subject of sludge will take on more importance in the future. The reasons for this are the increasingly strict controls on discharge methods and the obvious cost burden of every cubic meter of sludge.

Maintaining Greater Value In Bar Screen Performance
Before wastewater can be treated to minimize biochemical oxygen demand (BOD), nutrients, and pathogens, it is important to eliminate as much debris as practical, as early on in the treatment plant as possible, to avoid clogging pumps or compromising downstream performance. Careful consideration of design and operating factors can minimize total lifecycle costs and maintenance effort while protecting screening efficiency.

Sink Or Swim: A Comparison Of Submersible And Surface Mixers For Anoxic And Anaerobic Tank Mixing
With increasing requirements for enhanced nutrient removal, many wastewater plants are adding anoxic and/or anaerobic tanks in their secondary treatment systems. There are multiple options for enhanced nutrient removal including, but not limited to, the A2O (Anaerobic, Anoxic, Aerobic) process, the UCT or MUCT (Modified University of Cape Town) process and the Bardenpho process.

Dissolved Oxygen Measurement
One of the most important measurements in the determination of the health of a body of water is its dissolved oxygen content. The quantity of dissolved oxygen in water is normally expressed in parts per million (ppm) by weight and is due to the solubility of oxygen from the atmosphere around us.

Improving Compliance Through Real-Time Phosphorus Control
Levels of phosphorus, a chemical element that promotes organic growth, must be controlled in wastewater coming from beverage, food and dairy processing plants. Failure to control phosphorus accurately has a negative impact on water quality and can lead to large fines.

Textile Manufacturing
The textile manufacturing industry encompasses many and diverse processes that rely heavily on the use of water, energy, chemicals, and other resources. Wet spinning, sizing, desizing, scouring, bleaching, mercerization, dyeing and printing are just a few. Monitoring and controlling the pH, TDS/Conductivity/Salt Concentration, ORP (REDOX), and Temperature of the aqueous solutions used in these processes conserves costly resources, controls quality, and reduces the amount of pollution that must be treated before discharge of effluent wastes. This can be done manually with handheld instruments or automatically with in-line monitor/controllers.
