Confirming Natural Attenuation Processes at a Coastal Site - Case Study

Past waste disposal practices at a California coastal site resulted in a groundwater plume containing CVOCs (mainly chlorinated ethenes [CEs] and 1,1-dichloroethane) migrating offshore towards a marine harbor. CVOCs are present in the sediment porewater adjacent to the shoreline, but concentrations decreased significantly between 2000 and 2015, and NA in the marine sediments was suspected. To ...

Sterile wastewater treatment with vacuum distillation

Hygiene requirements are growing increasingly strict in many sectors, and the treatment of industrial wastewater is no exception. The vacuum distillation process in particular has to deal with the question of sterile treatment and subsequent storage of water obtained from the process. The mere possibility of reintroducing wastewater into the production process makes it imperative to prevent ...

The Importance of Dewatering

With spring comes two things: the onset of construction season for most of our country and rain- lots and lots of rain. The unpredictability of storms and the amount of rainfall is all a guessing game. Jobsites flood, work stalls and projects get delayed. Rain makes it hard to keep dry and on-schedule. What’s the solution? Dewatering is a technique used to control ...

How Do You Choose the Best Reverse Osmosis and Nanofiltration Membrane System for an Industrial Facility?

As global demands for clean water increase, more and more industrial facilities are looking toward membrane filtration solutions, such as reverse osmosis (RO) and nanofiltration (NF), to help manage intake, process, and waste water treatment. Using membrane filtration can help your facility reuse wastewater and virtually eliminate discharge fees, and depending on the industry or required use, it ...

Reverse Osmosis and Nanofiltration Membrane Filtration Systems: Common Problems and How to Fix Them

Reverse osmosis (RO) and nanofiltration (NF) are membrane filtration technologies that are designed to remove solute ions and molecules from a pretreated liquid stream. Well-designed RO/NF units are compact and demand relatively little maintenance, making them an attractive alternative to conventional treatment trains. Even despite the merits of today’s efficient RO/NF technologies, it pays ...

Determination of Flow Rates in part-filled Applications using the Radar Method

Introduction The radar measurement method plays an increasingly important role in the water and wastewater field. This is particularly reflected by the "Metering outside of the medium" trend. Flow measurement using radar which enables contactless measurements thus becomes a major focal point. It features a wide range of applications and hence is useful as permanent measurement system for ...

Scrubber Removes Grease and Particulates from Air Exhaust

Operating Issue A food-industry leader in Alabama operates several pork-sausage cookers that exhaust over 4,000 ACFM of moisture and pork grease. The operator installed Electrostatic Precipitators (ESPs) to treat the exhaust but these systems performed poorly and generated high maintenance and operating costs. Additionally, these systems were antiquated and required significant capital ...

Atomic Layer Etching – Changing the Art of the Possible

The society of vacuum coaters (SVC) deserves to be better known. It was founded in 1957 during a surge in the use of vacuum coating techniques such as sputtering and evaporation. The techniques go back a very long way: that man Edison filed a patent for coating phonograph cylinders in 1892 (It will never catch on). Did you know that the shiny surface inside your crisp packet is a vacuum ...

Oil Recycling - Case Study

The problem: Waste oil recycling contributes very much to climate protection through (CO2) energy saving. Compared to the production of base oil the re-refining of waste oil uses 34 % less resources. In the sixties the German government was subsidising the re-refining of waste oil. Because of that the use of waste oil as a fuel was neglected. The used oil re-refining is the ...

Tire Shredding: Alternatives to Landfills

For many reasons, whole tires pose a major problem to landfills. The most obvious is the inefficient use of space. The actual rubber of a tire takes up only a small fraction of the space a tire occupies, and the rest of the space is wasted. A less obvious but far more serious problem is that tires may trap methane gasses when buried with other garbage in landfills. When this happens, the tires ...

Industrial membrane processes in the treatment of process waters and liquors

A review on pulp and paper industrial membrane processes using a variety of modules and processes is presented. Membranes are mostly used today to purify process waters and to recover coating colours. Ultrafiltration using tubular membrane modules or cross-rotational (CR) filtration has been widely applied for the purification of process waters. The reuse of UF membrane permeate has decreased the ...

The role of process water in pathogen reduction

The USDA’s Pathogen Reduction/Hazard Analysis and Critical Control Point (HACCP) rule in July of 1996 required all meat and poultry slaughter plants to adopt a system of process controls to prevent food safety hazards. It contained four components: standard operating procedures (SOPs) for sanitation, HACCP plans, generic E. coli testing and Salmonella performance standards. With the ...
