Despite their best intentions, wastewater operations all over the country have suffered from accidently under- or over-administering treatment chemicals when trying to get effluent into shape. With the proper tools, however, these mistakes can become a thing of the past.
The Chiquita WRF plant was looking to improve the performance of their existing gravity thickeners better than the 2.3% DS that they were previously achieving. In their search for a solution they discovered the S-Disc technology from Huber Technology.
Many US wastewater treatment plants (WWTPs) are beginning to use anaerobic digesters to produce biogas that can be used in their combined heat and power plants to generate electricity and heat.
Written by Kaeser’s system experts, this whitepaper compares rotary lobe and screw blowers, isochoric and isentropic compression, and how to properly apply these technologies for designing an energy efficient system.
A brief introduction into sludge digestion by means of aerators and aerobic mixers that are located on-site is provided. Rationale for treating on-site as well, as is a discussion of sludge characteristics and how they may be addressed are similarly considered. This is an introduction only and will be followed by development of the topic in more detail in later papers. By Dr. J.H. Wakefield, consulting scientist/engineer
The Bissell Point Wastewater Treatment Plant is the largest wastewater treatment facility in Missouri with an average flow rate of 123 MGD. In the mid-1980s, the facility expanded to provide secondary treatment. The goal of the upgrade was to select a reliable process that would achieve high-rate BOD removal.
The CNSolution 9310 analyzer is used in precious metal processing to measure and control cyanide used in the hydrometallurgical leaching of gold and silver from the ore.
Stricter environmental policies and regulations worldwide are changing how industry approaches all aspects of business. Likewise, EU (European Union) environmental policies governing air, soil, and water quality have become progressively stringent.
These policy changes affect the power industry’s balance of meeting growing European energy demands with compliance to environmental standards. In order to conform with EU standards specific for flue gas, a coalfired generation plant (at the time owned by Endesa, Italia, S.p.A.) in Monfalcone, Italy, undertook the measure of installing a state-of-the-art FGD (flue gas desulfurization) system at their facility. This system would remove SO2 (sulfur dioxide) from the emissions for the 336 MW coal-fired power station.
Driven by tight budgets and competing needs for limited CAPEX funds, wastewater treatment plants are increasingly looking to reduce their operating expenses. Many are now referring to themselves as water resource recovery facilities (WRRFs), reflecting a heightened focus on recovering nutrients, methane, and a host of other properties from their waste flows. The largest boon to date has come from thermal energy, but producing biogas comes with its own set of challenges, including accurate gas flow measurement.
