EDUR DAF pump saves capital cost, energy and maintenance costs
A SINGLE dissolved air flotation pump is able to replace the entire air bubble system on DA F plants according to pump supplier Hydro In- novations.
EDUR multiphase pumps draw water in from the ‘clean’ end of the DAF tank as well as bring air in through a snorkel in the suction line.
The pump shears the air
and then feeds it at pres- sure through an enlarged solution line, then back into the DAF plant, pro- ducing a discharge stream into the tank that is satu- rated with 30 to 50-mi- cron air bubbles.
Conventional DAF sys- tems consist of a waste- water tank, compressor, air saturation vessel and effluent pump.
The effluent pump draws effluent from the tank and pumps it into the air saturation vessel.
A compressor pumps air into this same vessel.
The air/water mixture is ‘saturated’ under pres- sure, then released back into the wastewater tank at atmospheric pressure where tiny bubbles form and adhere to the sus- pended matter (fats, oils and other small wastewa- ter particles).
The bubbles (with their attached suspended mat- ter) float to the surface of the tank, where floatables can be skimmed off the surface.
By using EDUR mul- tiphase pumps, which can produce the same micro-bubbles, asset owners can do away with the compressor, the air saturation vessel and any control or ancillary com-
ponents for these items. The reduction of these system components and the simplification of the design results in lower in- vestment costs and higher
operational reliability. The EDUR multiphase pump is an efficient al-
ternative.
Now, one pump can re-
place the conventional pump, air saturation tank and compressor.
Energy and maintenance costs of running the com- pressor are eliminated.
EDUR multiphase pumps can deliver flows from 1l/s (for smaller DAF plants) to 15l/s (for larger DAF plants) and produce pressures to 12 bar (174psi).
A variety of materials and seal arrangements en- able EDUR pumps to op- erate in a very wide range of applications.
Available materials in- clude ductile iron, ‘gun- metal’ bronze, stainless steel and super duplex.
Mechanical seals are available as balanced, double and tandem.

Interim report
shows UK farming’s
progress towards
antibiotic use targets
RESPONSIBLE Use of Medicines in Agri- culture Alliance has re- leased a half-year sum- mary of the UK farm- ing industry’s progress towards achieving 2020 targets for antibiotic use in each of eight different livestock sectors.
The targets, developed last year by the Targets Task Force and pub- lished in October 2017, include a number of nu- merical and qualitative goals towards reducing, refining or replacing an- tibiotic use in UK farm animals.
RUMA’s secretary gen- eral Chris Lloyd said a comprehensive review of progress is due in Novem- ber.
“In the meantime, this four-page summary pro- vides a flavour of some of the activities being im- plemented to build on the
successful reduction of 27 percent in overall farm antibiotic sales for 2014- 2016,” he said.
Mr Lloyd added it’s im- portant to note each sector is very different – in terms of when they were first able to engage with the issue, disease pressure, number of producers and structure.
“This is why some have already made significant changes and are ‘refining’ how and when antibiotics are used, while others are working on bigger issues of data, communication and usage ‘hot spots’,” he said.
“But whatever the stage, all remain fully engaged on driving improvement and best practice to en- sure the targets can be achieved by 2020.”
