Wastewater Treatment

The Fluid Waste Management Choice – Water & Wastes Digest

Ultrafiltration (UF) excels at the clarification of solutions containing suspended solids, bacteria, and high concentrations of macromolecules, including oil and water. This is a pressure-driven process using membranes that are characterized by their molecular weight cut-off. No chemical additives are required. Ultrafiltration removes a variety of suspended solids and organic impurities from water and other solutions for optimum water management, […]

Evaporators Provide Economical Solution – Water & Wastes Digest

About the author: PRAB Inc. can be reached at www.prab.com or 888.324.2576. Evaporation is not only a natural phenomenon, but also a clean separation technology that has been recognized as a powerful technique for several industrial wastewater treatment processes to completely separate heavy metals, salts, boron, hardness ions, phosphates, surfactants and solids, which reduces wastewater volumes and produces high quality, […]

Blog: Considering Environmental Impact Beyond Mere Compliance

Wastewater treatment is an increasingly critical topic that has been discussed at the highest levels of government and major corporations. To find a sustainable approach, companies can employ many different strategies to help go beyond mere compliance and begin the process of positively impacting global water quality. According to the 2017 United Nations World Water Development Report, more than […]

Technical Brief: Eliminating Soluble Heavy Metal Ions From Industrial Wastewater by Precipitation and Ultrafiltration

Download Introduction Today’s manufacturers should be keenly aware of the problems—and especially the penalties—associated with discharging industrial wastewater into sewage treatment systems. The removal of soluble heavy metal ions from wastewater is a common industrial treatment requirement in modern manufacturing.   Some of the processes that generate waste streams containing heavy metals are: Electroplating Electroless nickel plating Printed circuit […]

Blog: Ultrafiltration and Precipitation: The Most Effective Methods for Removing Heavy Metals from Industrial Wastewater

Electroplating, electroless nickel plating, metal-forming operations, battery recycling and other such operations all generate wastewater containing soluble heavy metal ions. Ultrafiltration and precipitation are the most effective methods for removing these metal ions. Both help manufacturers avoid the costly consequences of non-treatment, that can include corrosion to systems, toxic pollutants passed into surface waters, sludge disposal, and more. Finding […]

Removing Heavy Metals from Wastewater – Products Finishing

Q: What are some tips you can give our shop about the proper removal of soluble heavy metal ions from from our wastewater? A: Today’s manufacturers should be keenly aware of the problems—and especially the penalties—associated with discharging industrial wastewaters into sewage treatment systems. Corrosion and other interference with those systems, exposing workers to toxic substances and hazardous fumes, expensive […]

Blog: Feasibility Study: Oil Emulsion and Rinse Water Waste Treatment with Vacuum Evaporation

Mechanical and surface treatment processes in the automotive, aviation, and appliances industries require large quantities of water and produce highly pollutant wastewater that cannot be discharged directly into the sewer without proper treatment. This requirement can easily increase a company’s operating costs. A feasibility study in each case for treatment of these wastes is recommended. This study was used for […]

Blog: Why Companies Should Care – Industrial Water & Wastewater Management

According to UN.org, more than 80% of all the wastewater from our homes, cities, industry and agriculture flows back into the ecosystem via lakes, rivers and other bodies of surface water, polluting the environment while losing valuable nutrients and other recoverable materials in the process. Guy Ryder, the Director-General of the UN International Labor Organization (ILO) and the Chairperson of […]

Blog: Making Wastewater Compliance Part of a Profit Strategy

Modern manufacturing operations are constantly looking for ways to innovate and increase productivity. This means making the most efficient use of any resource essential to the process. These resources, which can be finite commodities whose prices can fluctuate dramatically each year, often can be the drivers for increasing unplanned expenses, lowering efficiency, and impacting annual profits. Water is considered an […]

Blog: No More “Either Or”: How PRAB Chip Processing Equipment Can Pay for Itself…And Everything Else You Need

Wouldn’t it be great if you could have it all? With no more decisions about where to allocate your equipment budget or which purchases to prioritize, you could fill your facility with everything you need to maximize efficiency and increase profitability. Unfortunately, there’s no such thing as an industrial operation that has access to endless financial resources. At least we’ve […]
