Dairy production in Turkey Case Study
NEUTHOX® removes biofilm in cooling tower and leaves the water system completely free of unwanted bacteria Using an electrolysis process of saltwater the ECA generator produces the liquid NEUTHOX®, which contains hypochlorous acid, and is highly efficient in eliminating bacteria. A biofilm consists of living and dead organic and inorganic material collected on a surface, which in water ...

Bio Films in Recirculating Aquaculture system
A biofilm is an assemblage of microbial cells that’s irreversibly related to a floor and enclosed in a matrix of normally polysaccharide material. It can also additionally shape on a extensive kind of surfaces, along with residing tissues, scientific devices, commercial or potable water device pipe or herbal aquatic systems. A well-assorted organism inclusive of algae, micro organism, ...

Incorporating ROS in Ice-Making Machines Extends Shipping Shelf Life of Produce, Seafood and Meat Products
M&R farms in Birmingham, Minnesota uses JC 9465 as a primary solution for their packing facility. They have also incorporated JC 9465 into their ice-making machines improving product shelf-life as well as eliminating biofilm. By injecting JC 9465 into their water lines supplying the ice machines, the ORP readings went up from 451 to 632. Once it had been converted to ice, the readings had ...

Biomass development in GAC columns receiving influents with different levels of nutrients
Indigenous bacteria are essential for the performance of bio-filters for drinking water treatment. Yet it is slow and difficult to develop biofilm in a granular activated carbon (GAC) filter with low nutritional levels in the influent, especially during winter. In this study, the biofilm development in three laboratory-scale GAC columns with different types of influent was investigated in ...

Use of quick diagnostic methods in milking
The objective of the present study was to evaluate the usefulness of bioluminescence measurement and analysis of swabs taken from the surfaces of the equipment for determination of the hygienic state of a milking machine when biofilm is present on the surfaces. In addition the measurement of electrical conductivity of milk as a tool to detect cows with subclinical mastitis was examined. In the ...

Performance of an
in-situ rotating biological contactor in a recirculating aquaculture systemThe start-up and activation of a nitrifying rotating biological contactor (RBC) and its performance inside a culture tank of rainbow trout were studied. First, in a lab-scale operation, the system was fed with a synthetic medium containing a high ammonia concentration (567 mg NH4+-N L−1) and operated at a high hydraulic retention time (HRT) (6.5 days) to minimize the wash-out of the biomass and ...

Nitrogen removal from livestock and poultry breeding wastewaters using a novel sequencing batch biofilm reactor
A study was conducted regarding the biological nitrogen removal from the livestock and poultry breeding wastewater (LPBWs) using a novel sequencing batch biofilm reactor (SBBR). Nitrogen removal process was studied under three aeration strategies/modes, referred to as MODE 1, 2, and 3. The results showed that MODE 2 (one operation period: instant fill of LPBWs, 3.0 h aeration, 1.5 h non-aeration, ...

Distribution and characterization of anammox in a swine wastewater activated sludge facility
Anaerobic ammonium oxidation (anammox) is a novel biological nitrogen removal process that oxidizes NH4+ to N2 with NO2− as an electron acceptor. The purpose of this study was to examine the potential activity and characteristics of anammox in a conventional swine wastewater treatment facility, which uses an activated sludge system consisting of three cascade aeration tanks ...

JM Farm Pond Water Case Study
JM Farms, located in Kentucky, had been experiencing significant buildup of biofilm and slime in the water system. The biofilm and slime buildup led to water with a poor taste and odor, decreased water and feed consumption, longer flock cycles and fewer-than-expected head sold, which resulted lower revenue for the farm. Understanding the impact that better treated water can have on the key ...

AHPN inferences based on behavior of Vibrio bacteria
Summary: Vibrio parahaemolyticus, the pathogen associated with acute hepatopancreatic necrosis (AHPN), has both toxic and benign strains. It inhabits the stomachs of shrimp in a biofilm, which protects it from antibiotics and other treatments. As with V. cholera, V. parahaemolyticus tolerates a range of salinities, pH and temperatures. Both species readily piggyback on marine plankton and may be ...

A new reactor for denitrification and micro-particle removal in recirculated aquaculture systems
A ‘membrane-denitrification’ reactor (MDR) was developed and tested in a semi-technical recirculation aquaculture system in comparison to a double – without MDR – as reference system. The MDR consisted of a reactor with an ultrafiltration membrane unit for removal of micro-particles (e.g. sludge flocs, bacteria and parasites). Specific carrier material provided surfaces for biofilm growth in ...

Swabbing Water Lines – A Better Level of Water Awareness
We know that biofilm is a tricky thing. It grows quickly, harbors bacteria, protects that bacteria from cleaning agents, and then releases those bacteria back into the water, potentially causing severe health issues. We clean and sanitize regularly to try to keep it controlled, but how can we know how much bacteria are actually inside the pipes? Doing a drip sample gives us just a vague idea. ...

Ultrasonic Irrigation
Algae blooms can have a major impact on irrigation systems and cost producers time and money to clear clogged pumps, spray and drip lines, not to mention possible chemical application costs. WaterIQ Technologies™ and its partners specialise in environmentally friendly ultrasound technology for efficient and cost-effective solutions to combat harmful algae and biofilm. “WaterIQ helps ...

Lg Sonic Ultrasonic Algae and biofilm control for irrigation case study
Water used for irrigation can contain high levels of nutrients, some of these nutrients are beneficial for the plants watered, but can also lead to extensive algal growth. Algae in irrigation tanks can clog the irrigation system and can also be spread over the irrigated area. In addition, some types of fungus, also present in these waters, can be harmful for the plants grown. Therefore the ...

Rendering facility case study
The Problem: The Rendering Facility had experienced a catastrophic failure of an RBC system due a rotating assembly bearing and shaft failure. As a result, the existing lagoons became overloaded with ammonia from the anaerobic digestion process. The Solution: BioprocessH2O was selected to provide a bioFAS Moving Bed Biofilm Reactor (MBBR) System equipment package to retrofit and upgrade the ...

Use of sea water and hydraulic conditions. Potential cause of Mortality by Metals and Hydrogen Sulfide in Recirculation Fisheries
The traditional conception in Chile of the toxic effect of metals on cultured fish tends to weigh heavily on incoming freshwater in open flow fish farms as the major responsible for mortality in early stages of development in salmon species. This approach is mainly based on two conditions that refer to freshwater quality in Chile, and to the dilutive effect of recirculation fish stocks when a ...

Photobioreactors: Advantages & Disadvantages
What are open and closed algae culture systems? The two broadest methods of culturing algae at medium to large scale are split into two styles of system: open and closed photobioreactors (PBRs). A PBR is any device or system that supports the culture of photosynthetic organisms using light. There are photobioreactor advantages and disadvantages to both types systems depending on the goals you ...
