Abattoir effluent treatment A low-cost system for treating waste from abattoirs that uses two types of Munters wastewater treatment products, has been developed by UK-based BiOriginal. It combines the accelerated solids settlement capability of Munters TUBEdek with the high performance biological treatment provided by the company’s BlOdek media. In an installation for E.D. Jones abattoir in North Wales, a compact biological treatment system has been constructed. Using the two product types in GRP enclosures, it has resulted in a cost efficient, space-saving alternative to other forms of treatment. The system provides a solution to new regulations which limit the spreading of untreated abattoir waste on fields. Up to 7500 gallons per day of liquid waste from the abattoir is first treated in a sludge digester to treat the very high BOD concentrations. It is then passed through one of BiOriginal’s “SetLink” tanks to thicken and remove the produced solids from the liquor. The . . . . I.... * . . . *. . * “SetLink” unit incorporates B*...

Reemay and Fiberweb introduce new filtration media Reemay, Inc. and Fiberweb, sister companies at BBA Nonwovens, have joined forces to produce a new filtration media. UltraFlo is a trilaminate composite that incorporates spunbonded outer layers sandwiching an inner layer of meltbiown micro fibres. The outer layers provide strength and stability, while fhe inner layer gives filtering properties greater than 99.9 percent at 5 microns particle size. Composed of 100% polypropylene, UltraFlow has high tensile strength, low pressure drop and can be heat or ultrasonically sealed. It is suitable for liquid, air and gas filh-ation. UltraFlow is manufactured in a variety of weights, ranging from 15.5 to 88 grams per square meter or .46 to 2.6 ounces per square yard. The company has the ability to vary the outer supporting layers and the inner meltblown layer to meet the customer’s specific filtration requirements. UltraFlo is constructed of 100% polypropylene. The continuous filaments in the outer layers provide good edge stability with minimal tendency to fray or unravel after slitting or die cutting, and the surface layer construction provides exceptional tear and tensile strength and a smooth, low linting surface. It is chemically inert and resistant to most acids, alkalis, salts, solvents and oils, so the potential for contaminates to ieach out of the filter during use is almost nonexistent, claim its manufacturer’s.
