The City of Pearland is constructing a new 10 million gallon per day capacity surface water treatment plant (SWTP). The City has junior water rights to purchase 10 MGD raw water capacity from the American Canal, which is a man-made channel operated by the Gulf Coast Water Authority. The canal is fed by the Brazos River and natural drainage from the...

To meet the future population growth, the City of Pflugerville is expanding its WTP. This presentation will discuss project challenges and strategies, specifically related to maintenance of plant operation with membrane retrofit, and advanced planning to meet project schedule....

In 2013 CDM Smith prepared the Brazoria County Regional Water Facility study for the Brazosport Water Authority (BWA). The resulting recommendation was for the BWA to expand the water treatment, pumping and transmission system and to diversify their water source (with options such as brackish ground water) to improve water reliability during period...

Water efficiency (recovery) for industrial process and wastewater treatment is often limited by hardness and silica levels in the feed stream. In particular, water efficiencies above 90% often lead to significant operational challenges for membrane desalination systems. This presentation will discuss the challenges presented by hardness and silic...

Adoption of membrane bioreactor (MBR) systems continues to grow, even without space constraints or plans to further treat the wastewater for beneficial reuse. Municipal and industrial WWTPs are selecting the MBR process to achieve greater nutrient reduction and to have consistent effluent for surface discharge. These new drivers have also been coup...

Membrane degasification applications are primarily located downstream of MF/UF filtration equipment. Membrane degasification enables the reduction in dissolved gas in treated water which facilitates increased efficiency of downstream technologies such as RO, IEX, and ED....

Presentation will show the challenges associated with impaired water that includes arsenic, iron, gas, boron, heat, and the membranes selected for the RO system and the pretreatment system consisting of MicroFiltration. The major plant components includes chemical addition prior to PALL MicroFiltration system as a pretreatment to the conventional b...

Because of the historical cost and perceived complexity of MBR technology, there are still a limited number of large MBR facilities in operation in Texas (the majority of the existing facilities are package plants, less than 0.1 MGD). The goal of this presentation is to review case studies for different MBR facilities in Texas (some designed versus...

This presentation provides an overview of membrane bioreactor (MBR) processes and identifies options for incorporating flexibility in design. Several case studies are presented that show examples of flexible MBR designs while highlighting the suitabiblity of MBR as a technology for retrofitting existing wastewater treatment facilities....

Single-stage MBR technology is designed and engineered to be extremely simple to operate and optimize. This single-stage process uses one set of blowers to provide mixing, air scouring and process oxygen. Biologically treated wastewater is filtered using Silicon Carbide (SiC) membranes to produce reuse quality effluent with no recycle, no mechanic...

Membrane cleaning basics as it applies to micro, ultra Nano and reverse osmosis Membranes. when to clean how to determine that cleaning point, what cleaners to use and why. determining the effectivenesss of cleaning....

All the different analysis methods and tools that are used to perform a membarne autopsy will be discussed. In addition, the reasons why to have an autopsy perfomed, membrane selection for the autopsy, and interpretation of the results will be covered....

Presentation will cover safety while conducting chemical clean in place procedures. Presentation will begin with safe chemical handling procedures and continue with potential chemical piping system hazards. Presentation will end with a list of unsafe practices to avoid....

Recovery and efficiency are synonymous in an era of water scarcity. A new generation of Ultra High Pressure (UHP) systems rated for 1740PSI (120bar) address the challenges of concentration and osmotic pressure to open a new frontier of brine salinities above 80kppm, representing a convergence of established practices and innovative design with tod...

CCRO has emerged as the industry leader in high recovery, high reliabilty and flexible RO operation. The technology has been implemented in over a dozen industries and applications across the globe with system sizes ranging from 10 gpm to over 10 MGD. In this presentation, we'll review the performance of three (3) of the 250+ installations....

Membrane treatment plants represent efficient and effective means of treating various source waters. Microfiltration (MF) and ultrafiltration (UF) membranes are capable of removing particulate, bacteria and some viruses. When membrane plants run well, water quality is consistent, production capacity is dependable, and consumers can count on water t...
