  • Shrimp Processing Wastewater Treatment

    These jars show the treatibility with Floccin J and wastewater from cooked shrimp. The initial untreated water had a TSS of 1,230 ppm and a BOD of 3,000 ppm. The addition of 0.10 grams of Floccin J in 100ml (8.34 lbs/1,000 gallons) created a tight flock and a very clean effluent water quality. The treated TSS was less than 10 ppm and the BOD was 200 ppm. There was a significant amount of oil ...

  • Milk Processing Wastewater Treatment

    A milk processing facility was using a 800 hp evaporator to dispose of their 0.75% solids concentrated milk waste stream. The staff was interested in evaluating the effect of using the Floccin products to capture the majority of the BOD and send this higher % solids/BOD sludge to the evaporator. The idea was to reduce the electric hp by reducing the volume of water going to the evaporator. Their ...

  • Peach Processing Wastewater Treatment

    A major fresh pack operation of peaches and nectarines needed a screening system to remove the labels and peach fuzz from their wash water before it was pumped from the pond for irrigation use. Flow to the pond is a steady flow of 50 gpm, rising to 600 gpm during periodic draining of the peach coolers and washing systems. The water is a combination of wash water, labels and fuzz from the fruit, ...

  • Grease Processing Facility Wastewater

    Yellow & Brown Grease Processing for Biofuel This facility takes in yellow and brown grease and processes it to recover the organics for biofuel. The resulting wastewater generated is shown below on the left. The pH quickly drops to 4.67 as the organics anaerobically decompose thereby dropping the pH. Caustic was used to raise the pH to 6.4 and the addition of ...

  • Design development of an electrocoagulation reactor for molasses process wastewater treatment

    The impact of electrode corrosion behaviour, reactor geometry and current density on electrocoagulation efficiency were investigated for the treatment of molasses process wastewater. Two laboratory-scale vertical plate electrocoagulation reactors were used for this investigation: the first being a low aspect ratio bath reactor with a low specific electrode area, while the other was a high aspect ...

  • Development of downflow hanging sponge (DHS) reactor as post treatment of existing combined anaerobic tank treating natural rubber processing wastewater

    Conventional aerated tank technology is widely applied for post treatment of natural rubber processing wastewater in Southeast Asia; however, a long hydraulic retention time (HRT) is required and the effluent standards are exceeded. In this study, a downflow hanging sponge (DHS) reactor was installed as post treatment of anaerobic tank effluent in a natural rubber factory in South Vietnam and ...

  • Enzymatic oxidation of phenolic compounds in coffee processing wastewater

    Peroxidases can be used in the treatment of wastewater containing phenolic compounds. The effluent from the wet processing of coffee fruits contains high content of these pollutants and although some studies propose treatments for this wastewater, none targets specifically the removal of these recalcitrant compounds. This study evaluates the potential use of different peroxidase sources in the ...

  • Mixed micelles-mediated dephenolisation of table olive processing's wastewaters

    Olive processing wastewaters account for highly pollutant agro-industrial effluents. Their phenolic compounds are responsible for their toxicity. Those natural compounds have to be degraded or recovered before any discharge into the environment. This investigation deals with the extraction and concentration of the phenolic compounds into an aqueous phase using a mixture of nonionic/anionic ...

  • Toxicity reduction and biodegradability enhancement of cork processing wastewaters by ozonation

    Biodegradability enhancement and detoxification of cork boiling wastewater (CBW) are required for the successful implementation of biological treatment options. We studied the possibility of achieving these goals through ozonation pre-treatment by experimenting on the effect of ozone dose and pH. The CBW used had a pH of 5.81, a chemical oxygen demand (COD) of 1,865 mg L−1, a ...

  • Site Selection for Food Processing Facilities Wastewater Treatment

    Food processors face an ever changing production schedule which depends largely on the growers products, their finished product customers, labor, and the current market pricing. Many facilities are relocating or looking to relocate to decrease the fixed cost of overhead and labor to try and obtain a competitive advantage over their competitors, which can be only a few cents per pound of finished ...

  • Processing Wastewater Sludge Using Dewatering Containers

    The relative cost of dewatering equipment varies widely and is directly related to the processing rate. For smaller utilities that need to dewater sludge in batches, dewatering containers are an alternative that can be relatively inexpensive and simple when compared to other technologies on the market. The most common type of dewatering container is based on a roll-off box design, although any ...

  • The wastewater treatment of the food industry

    The wastewater treatment is a process which is used to recycle the wastewater into an effluent that can be reused again. This treatment helps in removing all the impurities from the water. Many industries are involved in this type of treatment to make use of water and not to waste it. Due to the scarcity of water, this type of water recycle is necessary. Many foods and beverage ...

  • A momentary look on food processing wastewater treatment

    The qualities and volume of wastewater released from food processing industries have created significant concerns for ecologists all over the world. However, the amount and quality of wastewater vary from industry and food processing types. While some food organizations prefer to discharge the wastewater in a particular period, some go for dispatching polluted water all over the year, which has ...

  • Investigation of Corfu-Greece reclaimed municipal wastewater suitability for irrigation

    Care in the reuse of processed liquid wastes from wastewater treatment plants (WWTP) plays a major part in the protection of ecosystems which are used as final receptors of urban wastewater, and provides an environmental answer to the creation of green areas around the WWTP. Research of all the necessary parameters for the safe use of processed wastewaters in soil irrigation gives answers to the ...

  • Survival of Helicobacter pylori in the wastewater treatment process and the receiving river in Michigan, USA

    Contaminated water may play a key role in the transmission of Helicobacter pylori, resulting in gastrointestinal diseases in humans. The wastewater treatment process is an important barrier to control the transmission of H. pylori. However, the presence and viability of H. pylori in the treatment process is not well known. In this paper, the ...

  • Development of a packed-bed reactor for the recovery of metals from industrial wastewaters

    Affinity separation is becoming well established for the purification and recovery of metals from industrial wastewaters. Although the method has been successfully applied on a bench-scale, there is a need for reaction engineering studies to scale-up the process for use in large-scale wastewater purification and recovery of valuable metals. In this study, a pilot-scale packed-bed reactor has been ...
