Drinking Water Treatment solutions, technologies, products, and processes used in a drinking water treatment plant.

Using Granular Activated Carbon To Meet DBP Regulations

The Roche Harbor Water Treatment Plant is located on the northwest side of San Juan Island in San Juan County, Washington state. Although a significant part of the land in the county is privately owned, the watersheds there provide a public benefit for both residents and visitors. San Juan Island’s economy is tourist-driven; the island was voted #2 on the New York Times list of “41 Places to go in 2011.” Its marina has been a top boating destination for more than fifty years. Incorporated in 1886, the community has seen slow but steady population growth in recent decades. Roche Harbor Water System Inc. has been in operation since 1968 when PVC piping replaced the island’s existing wooden pipe system.

Using ‘TransMembraneChemiSorption’ (TMCS) For Ammonia Removal From Industrial Waste Waters

Municipality Removes Biofilm, Improves Water Quality, Lowers Dosage With MIOX
Looking to reduce potential disinfection byproducts issues that new and difficult regulations were requiring, a Tennessee municipality began investigating alternative water treatment disinfection methods in an effort to reduce the potential liability (RMP) involved with using and storing gas chlorine. Within months of switching to a mix of oxidants (MOS), a difference was noted in the systems residual, residual was no longer dead spotting in low flow areas, and much higher residual was noted in areas that had been difficult to maintain At the end of the first year of operation the municipality had also documented a reduction in their disinfection byproducts formations, specifically both TTHMs and HAAs, which were both reduced by 50% in direct comparison with the quarterly results from the previous year.

Seawater Desalination At Rabigh Refinery Saudi Aramco’s RABIGH Refinery in Saudi Arabia wanted to install facility for 10000 TPD Seawater Desalination for the industrial use. The facility was supposed to be a BOOT (Build Own Operate Transfer) basis. By Aquatech International Corporation
Ozone Demand Testing = Disinfection Project Success
Water and wastewater facilities are increasingly looking to ozone disinfection. A strong and indiscriminant oxidant, ozone can effectively address treatment issues with THMs and DBPs in the disinfection process. Ozone disinfection is also a proactive step toward addressing future rules on endocrine disrupting compounds (EDCs) and other trace organics at both water and wastewater plants. While there are many aspects to ozone disinfection system design, the single most important factor in project success is a thorough understanding of your facility’s ozone demand profile. This article provides an outline of the key factors to make your ozone demand test -and ozone project- a success. By Thoram Charanda and Louis LeBrun
New Media Reduces Cadmium From Electroplating Wastewater Discharge
Cadmium has many industrial uses and is predominantly used in rechargeable batteries, in yellow and red pigments and is widely used in the aircraft industry electroplating applications due to the excellent resistance to corrosion for cadmium plated steel components.
Case Study: Optimized Quality Control In Mineral Water Plants Due to microbiological activity in the process, or to a lesser extent due to the reduction in nitrate levels in the raw water, nitrogen compounds may give rise to increased nitrite concentrations. By Endress + Hauser, Inc.
Case Study: Biological Filtration For Iron And Manganese Removal
In an earlier paper, the author reviewed the physical and chemical processes conventionally used to remove iron and manganese from groundwater, and explained how the process most commonly used in France (aeration plus filtration) led to the discovery of coincident biological phenomena. These were subsequently applied to enhance the performance of certain existing units and, especially, to serve as a basis for a new generation of biological treatment plants offering sharply improved performance levels. These general considerations will be illustrated by a number of examples, selected from among nearly 200 existing facilities. By Pierre Mouchet, Manager of Technical Assistance and Information

Waste Heat Recovery For Desalination From Steam Power Plants

Everything Old Is New Again
As water treatment plant managers face relentless challenges — aging infrastructure, stricter watershed protection regulations, higher energy costs, growing water scarcity, and tighter budgets — solutions are emerging that blend computer-age technology with the tried-and-true practice of granular media filtration. By Jim Lauria, Senior Vice Director-Water Treatment, Bilfinger Water Technologies
Generating Disinfectants From Water: Could In Situ Electrolytic Production Be The Future?
Chemical disinfection using strong oxidants involves the transportation, storage, and handling of unstable and/or aggressive and hazardous chemicals. The production of oxidants at the location where they are to be used has therefore been a preferred option, especially in small-scale or remote installations. On-site electrolysis of NaCl for the local production of chlorine or hypochlorite, or the production of ozone-enriched oxygen by silent discharge has been standard for years. However, it is possible to take the idea of producing chemical disinfectants locally a step further and look at in situ techniques, i.e. at devices, which produce oxidants in and from the water to be treated.

Instrumentation: Dos And Don’ts For The Water Industry
To say that instrumentation, automation, and control are key to the modern wastewater industry is somewhat of an understatement. With growing populations, tighter consent parameters, and the need to do more for less, operational efficiency is more and more important.
Laboratory Analysis Demystified
Most people have no idea how critical getting a good sample is, and how hard it is in general to get really good data. The analytical process for almost anything we test for has so many steps – each of which compounds any deviations or discrepancies made in the previous steps – that it’s vitally important to be as accurate and precise in each step along the way in order to get good, meaningful data in the end.
