INDUSTRIAL WATER AND WASTEWATER TREATMENT
Rethinking Aeration: Demand-Based DO Control And Energy Optimization
Aeration control strategies often remain conservative and static. Blowers operate continuously, oxygen levels are maintained near maximum, and airflow rates are rarely adjusted in response to real-time biological demand. The result is widespread over-aeration — a condition that does not improve treatment performance but significantly increases operating costs.

Capacitance Level Switches Provide Reliable Water/Oil Interface Detection
There are a number of point level approaches to measuring the interface between water and oil for water dump control in the oil and gas industry. However, each has disadvantages — manual methods introduce human error, conductivity switches are rendered inaccurate by buildup, and float switches are susceptible to wear and tear. This white paper introduces capacitance level switches as an accurate and reliable alternative for water/oil interface detection.

Resolving High PH For Mining Operations
For an open-pit taconite mining operation in Minnesota, high pH groundwater required round-the-clock pumping to comply with discharge permit limits. After management installed a control system to neutralize the pH, the treated water leaving the site now meets permit limits. Read this case study to learn more about the installed system and results.

Doublethink In The Desert: The Myth Of Recycling In The Permian Basin
Everyone is familiar with the water cut statistics: three to seven barrels of produced water emerge from the ground per barrel of oil. This oft-cited statistic is useful to appreciate the scale of the volumes of water produced in the Permian Basin. However, it does not tell the whole story.

A Better Option For Water Transfer In Oil And Gas Applications
Until recently, it was difficult to find an optimal meter for the harsh conditions that can occur during water transfer in oil and gas applications. The good news is that an effective, accurate, and rugged meter is emerging as an alternative.

SDOX Technology Mitigates Sulfide Production By Promoting Aerobic Environment
The Plant’s wastewater treatment facility uses four, covered anaerobic lagoons to manage BOD, pretreating wastewater prior to sending the effluent to a pumping station which directs the wastewater into the municipal collection system for final treatment at the City’s wastewater treatment plant. Read more to learn how the company used hydrogen peroxide and a catalyst to maintain an aerobic environment but was unable to adequately mitigate the odor from the facility’s wastewater.

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.

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.

MBBR Technology Helps Plant Maintain Discharge Compliance, Achieve Sustainable Growth
A bacon processing plant in the Midwest was overloaded by more than 50%. Even though the system continued to maintain compliance, the plant proactively decided to expand its wastewater treatment facility to ensure they met their growing demand and maintained their standing as exemplary corporate citizens and environmental stewards.

Industrial Flow Measurement Basics And Practice
In the recent decades, the market for the products of the industrial process industries has changed greatly. The manufacture of mass products has shifted to locations where raw materials are available economically. Competitive pressures have forced a swing to specialization as well as to an ability to adapt to customers desires. The systems are designed so that the economic data, such as raw material properties, raw material costs, batch sizes, are quickly integrated into the processes. An important consideration is the assurance and improvement of product quality.

Better Drinking Water Quality Starts Upstream
While every potable water treatment process requires a balance of chemistry and biology to deliver safe, clean drinking water, added concerns from upstream stormwater or agricultural runoff only make the job that much more difficult. How can we do a better job of safeguarding water treatment plant (WTP) operations while protecting the health of water utility customers against threats of upstream nonpoint source (NPS) pollution?
