FILTRATION SERVICES LTD

Filtration Services offer bespoke manufacture and design to meet both your site specific requirements and the exacting standards of today's industry. Our Rotavac rotary drum vacuum filter (RDVF) is particularly suited for applications where large amounts of liquids and solids need to be separated continuously and with minimal operator input. The Rotavac is available in a variety of sizes, from 0.8m² up to 60m² filtration area, and in a range of solids discharge configurations. Rotary drum vacuum filters operate continuously with the solids and liquid being discharged at steady, predictable rates. The units require little or no manual intervention, being simple to operate and maintain. Contact us now for more details and your individual solution.

The Rotavac One is our complete compact pilot filter station. Easy to install and operate it is ideal for small volume applications, process validation and pilot-scale trials. The unit has a small 2m x 1m footprint, comprising of 1.3m² skid mounted rotary vacuum drum filter (RDVF), filtrate receiver, filtrate pump, vacuum pump, blower (scraper discharge version only), local control panel. Two versions are available: Rotavac One S, scraper discharge and Rotavac One P, precoat discharge. These filters are ideal for larger test programmes under actual manufacturing conditions. We can provide filter media from our extensive range and advise on this if required. Please contact us for more information if you are interested in purchase or hire of our pilot filter.

The Rotavac Lab is a fully functional and representative lab scale rotary drum vacuum filter (RDVF) and filtration system, generally used for product evaluation tests or as a preliminary step towards pilot scale and full scale equipment trials. The unit can be used to validate the suitability of this type of continuous vacuum filtration equipment. The equipment offers the advantage of an easily interchangeable discharge system so that different configurations can be trialled if required. It is supplied with a control panel for modifying drum and agitator speeds and, when using a precoat discharge, the knife advance rate. A separate skid mounted feed tank, mixer and feed pump is included with the RDVF. The unit is easy to assemble and we can provide full detailed instructions including photographs at the point of hire. We include filter cloths from our extensive range of fabrics. Please contact us for more information if you are interested in purchase or hire of this lab filter.

Possibly one of the simplest filtration units used in industry today, the tipping pan filter is ideal for batch processing rapid-settling, fast-filtering crystalline suspensions. The filter is an open-topped vessel which is fitted with a false base, drainage grids and filter medium. The solid/liquid suspension is fed onto the surface of the pan and, at the same time, vacuum is applied to the base of the pan. The vacuum assists in dewatering the suspension thereby producing a filter cake on the filter medium. The filtered liquid (filtrate) is collected from the base of the pan through a special valve assembly. The filter cake can be washed in the pan as many times as is required by the process to achieve the desired product purity. Once the washing stage has completed, the pan is inverted and the filter cake is discharged.
