1. Can I wash cloth with a portable high pressure washer? Yes, provided the hose has a fan and not a needle tip. The wand should be moved over the cloth consistently and not held in one position. 800 to 900 psi is probably an adequate pressure to clean cloths. If cleaning is not efficient then consider chemically removing embedded particulates. (See Question #2) 2. Can I chemically clean my Filter Cloth? Chemical cleaning of filter cloth is a very effective way of rejuvenating filtration performance. Polypropylene cloths will accept both caustic and acid cleaning, Nylon and polyester fibers require more careful selection of the cleaning medium - contact us for help. REMEMBER - precautions must always be taken when handling chemical cleaning solutions! 3. Why does my Filter Press leak around the edges of the Plates? The filtration characteristics of specific slurries will affect filtration efficiency and having too much back pressure will result in edge leaking. Poorly designed filtrate discharge piping, higher than recommended pumping volumes or incorrectly selected filter cloth all cause or contribute to this problem. 4. Can I reduce my cycle time? Normally the slurry characteristics determine cycle time. Conditioning of the slurry can improve the dewatering time. Thinner cakes will also reduce cycle times and are more easily washed. 5. What is the highest pressure I can pump to my filter press? Filter presses are designed generally for two pressure 7 and 15 bar (100 and 225 psi) although special machines are made for higher pressures. Check the equipment manual to ensure you do not exceed the pressure your filter framework was designed for. If you need assistance measure your cylinder ram size, note the hydraulic pressure and contact us for help. 6. What is the best pump for a filter press? Many pump types are used with good results, depending upon the characteristics of the material being processed. Air diaphragm pumps do not shear flocculated slurries and are the most common type of pump used. An added advantage to this type of pump is that the air drive stalls when filtration is complete. Positive displacement pumps are used on high pressure filters. 7. Can I try samples to see if they work? We will provide a small number of samples at no charge for initial evaluation. It is usual for us to require some information on the conditions and your goals prior to making recommendations. 8. How do I extend my cloth life? Cloth life is shortened by mechanical damage, which may be caused by chemical attack or mechanical abrasion or both. Life is also shortened when cloth becomes blinded. Write down all the operating conditions and in particular changes that you have made and forward them to use for recommendations. We have a questionnaire for this purpose. 9. How long may I store filter cloth? Micronics synthetic cloths may be stored indefinitely, they are not affected by mildew or insects. Ultraviolet light will weaken polypropylene and these cloths should be stored inside. 10. How can I buy spare filter plates for my filter press? Questionnaires are available to help fill in the correct dimensions. Filter plates are custom made for the particular brand of filter you have. We can manufacture plates to the correct specification for any brand of filter. 11. How can I tell if my cloth needs replacing? Filter cloth that has performed well (which indicates it was the correct design for your conditions) will eventually have to be replaced. Usually, the filter cycle times will be longer and the filter cake will become progressively wetter. If your cloth has not performed well from the start then you need to modify the design. 12. Can I change the type of filter plate I have? Yes, any type of filter plate may be retrofitted to any filter press. You must only adhere to the maximum operating pressure of the filter press frame. 13. Can I arrange for a service call to refurbish my filter at my facility? Yes we can arrange for technicians to visit to conduct the work on site. In many cases it is possible for us to supply parts that may easily be installed by your personnel, saving you money e.g. replacement polypropylene filter plates, hydraulic systems, control panels, automatic and semi automatic shifters. 14. Can I easily replace my existing hydraulic power pack? Yes, we manufacture modular power packs for both air/oil and electro-hydraulic closure. These are easily installed in any brand of filter press and are capable of running simple and automatic machines. In some case it may be required that an additional control panel is included.
