Dual Parallel Lateral Filter Underdrains Selected To Replace Underperforming Nozzle Design At Mexico's Largest Drinking Water Treatment PlantLocated about 78 miles (125 kilometers) west of Mexico City lies the municipality of Villa de Allende, home of Mexico’s largest potable water treatment plant. The Los Berros water treatment plant was constructed in 1980 by the National Water Commission (Conagua), an agency of the Mexican government that manages the nation’s drinking water and wastewater treatment. The plant provides 396.3 million gal/day (1.5 billion L/day) of water to the country’s capital city, equivalent to approximately 25 percent of the total water supply of the western hemisphere’s most populace metropolitan area.

WASTEWATER FILTRATION PRODUCTS
FiltraFast™ is a high-rate downflow gravity or pressure filter that uses a unique compressible media. The filter only uses hydraulic loading to create the required media porosity without any mechanical compressing devices. A proprietary backwash sequence enables maximum recovery, extends media life, and limits energy consumption. This process 1) significantly reduces the footprint compared to sand filters, and 2) reduces maintenance and replacement costs required by disc filters, and other compressible media filters.
WesTech granular activated carbon (GAC) contactors are an effective means for removal of low-molecular-weight contaminants from aqueous solutions.
The Hydrotech Discfilter provides proven experience for today’s demanding wastewater treatment applications through an efficient, yet easy-to-operate design. Influent flows by gravity into the center drum and then passes through the filter media mounted on both sides of the discs.
At Jacobi Carbons, we take our environmental responsibilities very seriously. We are the only coconut shell carbon manufacturer with the foresight to have attained ISO 14001, the only globally accepted standard for environmental management. With the commitment of our entire organization we have been able to achieve the delicate balance addressed by the standard of maintaining profitability while reducing environmental impact.
Low-UC anthracite filter media extends the life of your filter before the media must be changed out. Low-UC anthracite typically produces consistent improvements in turbidity removal, due, in part, to more efficient solids loading.
Whether your needs are pre-planned or require emergency response, Aria™ FAST mobile water solutions provide reliable treatment with intelligent controls to keep your water, and business, flowing. Our global footprint ensures that we can respond with a plug and-play, fully equipped water treatment unit within 24 hours. Single units can produce quality filtrate of 400 gpm to 1400 gpm (73 to 320 m3/hr), while multiple units can be configured for larger capacities.

WASTEWATER FILTRATION PODCASTS
For water utilities facing various water contamination issues, there is no single catch-all treatment. That is why in this recent Water Talk interview Ronit Erlitzki and Doug Craver of AdEdge Water Technologies share treatment options that can be used alone or in combination to address diverse challenges. They introduce a new reverse osmosis (RO) treatment technique capable of raising recovery rates by 20 percent and reducing concentrate volume up to 70 percent vs. conventional RO (depending on water quality). They also explore biological processes for removing nitrate, VOC, ammonia, etc. and treating high brine concentrations in wastewater, plus techniques for resolving ammonia problems in water with high TOC concentrations.
As storm activity continues to grow, utilities are under increasing pressure to mitigate sewer overflows. Building enough storage to handle the excess runoff until it can be treated is no longer practical — in most places, it’s not even feasible to create a large enough space — and the issue will only get worse as storms continue to intensify. Meanwhile, most settling technologies that address overflows require chemicals and a complex process to start up, shut down, and store through off-peak times.
Filtration has been around for a long, long time, so it may be that most treatment plant operators feel pretty informed about its capabilities. But hearing from Brian Frewerd, Director of Application Engineering with Parkson Corporation and Water Talk guest, will likely prove enlightening. Frewerd provides background on sand filtration for tertiary treatment applications, followed by insight on notable technology improvements and performance milestones
Membrane bioreactors (MBRs) are not new, but they are the subject of renewed interest among utilities, and for Carollo Engineers Vice President Andrew Gilmore. He sat down with Water Talk's Todd Schnick and Kevin Westerling to discuss the MBR renaissance and the reason for their rise in popularity.
Jon Loveland, Global Practice Leader - Alternative Water Supply at Black & Veatch, shares insight on a major development for membrane bioreactor (MBR) systems and potable reuse.
If you don’t need the performance of an ultrafiltration membrane but also want to avoid the large footprint of a conventional media filter, you might want to consider FiltraFast extreme rate compressible media filters. As Ryan Hess, Director of Advanced Separation with SUEZ Water Technologies suggests in this Water Talk interview, “They provide roughly ten times the hydraulic loading rate of conventional media filters.”

World Water Works’ DEMON process can solve the problem of returning high concentrations of ammonia to the plant influent. The true key to the success of the technology is the patented advanced biological process controls and the physical separation used to facilitate the growth and retention of the anammox bacteria.
World Water Works specializes in the combination of the MBBR technology with Integrated Fixed Film Activated Sludge (IFAS) technology or Dissolved Air Flotation (DAF) technology for advanced wastewater treatment.
Water. It’s vital to human life, our economy, and ecosystem - the very survival of our planet. But water challenges are growing more intense than ever before. Increasing volatile weather patterns fueled by climate change, crumbling infrastructure, pollution, and over population that is causing a surge in the demand for water. This means the world’s supply of clean water is rapidly declining putting our future at risk.

ABOUT WASTEWATER FILTRATION
Wastewater filtration is often part of the tertiary treatment process that involves the final removal of suspended particles from water that has passed through both the primary and secondary treatment phases and immediately precedes disinfection. As the water passes through the filter, residual suspended material and bacteria is trapped in the filter and are removed from the filtered water. Passage can be blocked by physical obstruction, biological action, adsorption, absorption or a combination of ways. Wastewater filtration is usually the final step in the solids removal process.
With regulations increasing around wastewater effluent, the use of ultrafiltration and microfiltration systems in further polishing effluent has grown. Sand or activated carbon filters can provide a media for bacterial decomposition of nutrients, converting nitrates into nitrogen gas. The rise of water reuse applications is also fueling the increasing use of filters during the final polishing stages of the wastewater treatment process.
