Palm Pre|

devzor asked:


Wireless rechargeable devices are just now beginning to show up on the market. An example of this is the upcoming Palm Pre. I was wondering, why the Sonicare, an electric toothbrush, has wireless recharging (and has had the feature for several years) and other devices, like laptops or phones, don’t.

we are a bathroom-soap manufacturing firm currently using an old plate and frame filter press (manual, rachet type) which is used to separate a tallow mixture (beef+palm oils, it also contains NaO-0.17%-0.19%, NaCl-2.1%-3%, Glycerol 1.4%-1.44%) at 110-115 Celsius temperature, max 2 barr pressure, which is fed through a 5 hp centrifugal pump.filter cloth D44(28*56) is used with 36 plates and 37 frames. it works at a rate of 2800 Kg/Hr of flow (filtration capacity of 10 tonn/hr) and after every 3 hours processing, it is completely filled with cake so needs to be cleaned. Now, what i want to know is that would it be feasible if we install a pre-filter just before the filter press or any other means to make it more efficient.

we’re using the following chemical for bleaching purposes: http://www.pncil.com.pk/ourbrand.htm (good earth super FF).

2 different thickness of filter clothes are used alternately in the press, at the same time, to assure maximum cleaning, made up of polyester.
