  • The Upside Of Being Compelled To Treat Wastewater
    grossly polluted posing major threats to animal plant and human health That s what makes the whole situation such a hard pill to swallow Damned if you do damned if you don t It can certainly be seen this way but there are alternative ways to approach the problem In fact many facilities in the meat and poultry processing industries have found hidden value in the proper management of their wastewater One such facility is in north Georgia the poultry capital of the U S This facility processes upwards of 400 000 birds per day generating over two million gallons of wastewater laden with fat trimmings oils bone and offal In their wastewater treatment building they ve laid out a process for recovering these solid materials from the wastewater and selling them to a renderer As a result of operating this product recovery system the facility generates additional revenues of 2 million per year and dramatically reduces sludge disposal costs They meet the water quality requirements for discharging to a local stream and actually come out with wastewater management figures in the black The key for this facility is in realizing that the old adage one man s trash is another man s treasure actually applies to their business They identified a buyer for inedible animal proteins and established a relationship where both parties get what they want at a price they agree on Another facility this one in Australia processes waste material from a beef slaughterhouse into tallow an oily product that has a variety of industrial uses During plant wash down some of the raw materials end up in the wastewater system and instead of attempting to biodegrade the organic materials in their wastewater lagoon they installed a small dissolved air flotation DAF system to recover the product

  • Mutag BioChip High-Performance Biofilm Carrier Used In Municipal Wastewater Treatment
    STP s by applying Mutag BioChip carriers Fig 1 and 2 Mutag BioChip high performance carrier media for biofilms uncolored w o biofilm white and colored w o biofilm orange Before the reconstruction measure the STP oberes Surbtal had been operated with activated sludge process and was originally designed for treating the sewage corresponding to 16 000 population equivalents PE In 2012 and 2013 the reconstruction measure was performed in multiple steps by the Swiss company Techfina SA located in Winterthur whereas the process technological designing of the new moving bed bioreactor stage MBBR was effected in close cooperation with the technology provider Multi Umwelttechnologie AG After the reconstruction the STP is now treating the sewage accounting for 20 750 PE and is designed for automatic permanent operation with hybrid process combination of activated sludge and MBBR process The scope of the plant reconstruction was the supply of the complete electro mechanical equipment for the biological wastewater treatment hybrid process of the return sludge pumps as well as the blower station by the company Techfina SA The biological treatment stage of the STP consists of three identical trains whereas each train comprises three treatment zones Within the scope of the reconstruction measure the respective nitrification zone of each treatment train was equipped with Mutag BioChip high performance biofilm carriers Fig 3 Sewage treatment plant oberes Surbtal The biological treatment part of the plant consists of three identical treatment trains Fig 4 Ammonium oxidizing red and nitrite oxidizing bacteria green in a pore of the Mutag BioChip carrier Each single nitrification stage has an active reaction tank volume of 200 m and is filled with 27 m Mutag BioChip carriers Hence the carrier media fill fraction accounts for 13 5 percent of the active reactor volume which is available for the nitrification process As mentioned above the plant had originally been operated with activated sludge process which is characterized by the pollutant degrading bacteria being present in the form of activated sludge flocs which freely move in the wastewater After the plant reconstruction the nitrifying bacteria attached themselves to the Mutag BioChip carrier media The previous activated sludge reactors are now being operated with hybrid process also called IFAS combination of MBBR and activated sludge process whereas the biofilm carriers are retained by a system of carrier media retention screens installed in the respective nitrification reactor Accompanied by the pollutant load which increased according to the upgrade target of the plant the correspondingly increased oxygen requirement had to be considered Consequently the existing blower station was equipped with more powerful blowers The aeration systems which had been available in the reaction tanks earlier were completely replaced with high performance plate type membrane diffusers Within the scope of the upgrading measure of the STP oberes Surbtal 81 m of Mutag BioChip carriers in total were filled into the previous activated sludge tanks at similar percentages and the treatment concept was hence changed from activated sludge process into hybrid process IFAS In this

  • When Product Recovery Systems Are Sound Investments
    industry topped 18 5 billion in 2014 a nearly 15 percent increase over the previous year Among the frenzy of new projects lining up in the near future we can expect a good chunk of change to go toward environmental management programs at these facilities with wastewater treatment infrastructure representing a meaningful slice of the project pie As with all major expenditures whether or not to go forward comes down to the figure at the bottom of the ledger and a couple questions Will it make me more than it costs How long until it pays itself off Arriving at definitive answers to these questions means considering a lot of different financial variables including costs for equipment installation training operations and maintenance One modern approach in wastewater process design that has opened up interesting conversations in project budgeting is the idea of building product recovery systems The basic tenet of the process is to either Recover the product because it holds commodity value and can be sold to a buyer or reprocessed in house Recover the product to reduce the load on the downstream process equipment and achieve lower operational costs or Some combination of both An example of the first scenario comes from a rendering facility in Australia They installed a dissolved air flotation DAF system to recover oily solids that entered the waste stream during plant wash down These solids are then reprocessed into tallow a commodity product with various industrial uses The product recovery system was a 200 000 investment that took four months to get online In the end the investment was well worth it as the system recovers enough product to add 2 million a year in revenues An example of scenario 2 uses a similar equipment set up however the motivations are completely different An automotive manufacturing plant uses heavy oils in their process so naturally during equipment sanitation some of that oil is washed away as part of the wastewater The product recovery system is designed to capture as much of those oils as possible without adding any chemicals to separate them from the water The effect here is to reduce the chemical costs associated with removing all the oil in another separation tank This product recovery system saves tens of thousands of dollars a year in chemical costs A third example this time for scenario 3 comes from an oilseed processing facility An oil water separation system recovers free and emulsified oils for reprocessing thereby reducing the chemicals required for clarifying the wastewater to a quality suitable for discharge into the sewer The product recovery system adds to the plant yield and reduces operational costs in the wastewater treatment process Each product recovery system in these examples has a positive financial impact in the plants where they operate There are a lot of different industrial applications where a system such can prove to be a worthwhile investment Poultry and meat processing Rendering Vegetable oils Metals mining and manufacturing Refineries With as much

  • Tangential Flow Separation A New Way To Treat Waste
    this regard and I have considered it best to address them as tangential flow separators These devices are liquids solids separators employing a unique principle whereby leaky hoses utilize a laminar flow vector for the solid phase and a tangential flow vector for the liquid phase The fluid path is contained within a tube or hose if you like and the solid phase is forced down and out of the lumen of the tube The liquid phase is collected by a mesh membrane of sorts and for you chemical engineers out there is related to a modified Frasch process minus the high pressures and temperatures The solid phase continues down the tube where it is collected The result is the removal of the solid phase from the liquid and the dewatering or desolvating depending on the solvent of the solid phase As it results in removal of particulates and their concentration for disposal or other applications these may be considered as primary treatment devices If the waste stream has a specific character such as a waste stream from a plating operation these devices could be used as such But that s not the whole story nor the designed intent Tangential flow separators have in fact been designed as tertiary treatment devices to address recalcitrant waste streams with difficult to remove regulated and or dangerous components This is the result of a package of coagulants flocculents designed specifically to address these situations A not uncommon method of addressing these problems involves the oxidation of offending ionic species such as Cu Cd Pb and others as well as sequestering those anions PO 4 that form insoluble precipitates and or complex ions and then utilizing the principle of ion exchange to remove other offending anions NO 3 This involves a clay usually a montmorillonite an inorganic coagulant alum or ferric ion compound and a specially formulated polymer usually a cationic polymer to complete the removal process The big advantage of this tangential flow separator technology is that it lowers the cost by controlling the cost of the polymers necessary though not eliminating their usage and by allowing the use of zeolites specifically clinoptilolites to both remove and bind a variety of offending ionic species Clinoptilolites are zeolites that function as scavengers for both anions and cations become highly charged and are readily removed as larger particulates from the liquid phase Considerations Regarding Flocculants It is incumbent upon one wishing to separate solid and liquid phases to have them clearly delineated The more completely they are delineated the more effective the results To this end different coagulants flocculants are employed depending on the waste stream that is encountered Included among these are natural flocculants such as the montmorillonite clays Bentonite for example as well as various volcanic clays including the various forms of zeolites clinoptilolite for example Either mixtures of these coagulants flocculants are used or possibly those with additions of processing chemicals including various inorganic salts and polymer ion exchange moieties in order
