Support Sheets for beer and beverage

Short Description:

Great Wall S series is a new type of washable, reusable support sheet for pre-coat filtration in diatomaceous earth frame filters that you can use to achieve particularly high performance in the food and beverage industry.

It is a reliable partner for classic solid liquid separation to retain any filter aids which have been applied both as a pre-coat and as a body feed addition to the main unfiltered product. Not providing a considerable degree of clarification of their own, these filter sheets only serve as precoat support, while the kieselguhr or any other filter aid deposit represents the effective filter medium.

Its high wet strength and optimized surface enable a service life up to 30 precoat cycles, depending on the liquid to be filtered and the filter aid used. The sheets’ total throughput is determined by the quality of the filtering aids deposit.

*These figures have been determined in accordance with in-house test methods.
*Effective removal performance of filter sheets is dependent on process conditions.

SCP Support sheets Regeneration/Backwashin

If the filtration process allows regeneration of the filter matrix, the filter sheets can be forward and back washed with softened water without bio burden to increase the total filtration capacity and thus optimizing economic efficiency.

Regeneration is carried out as follows:

Cold rinsing
in the direction of filtration
Duration approximately 5 minutes
Temperature: 59 – 68 °F (15 – 20 °C)

Hot rinsing
forward or reverse direction of filtration
Duration: approximately 10 minutes
Temperature: 140 – 176 °F (60 – 80 °C)
Rinsing flow rate should be 1½ of the filtration flow rate with counter pressure of 0.5-1 bar

Please contact Great Wall for recommendations on your specific filtration process as results may vary by product, pre-filtration and filtration conditions.
