In the sludge treatment process, many sewage companies said the use of the original sludge filter often appear in the clogging of the filter cloth, so you need to dismantle the filter cloth, rinse clean and then loaded, one to take a long time , Sludge treatment efficiency is very low. What causes sludge filter press filter clogging what? How to solve in order to avoid clogging filter to improve sludge filter press efficiency?
1. Sludge filter press cloth itself, the material used, the size of the filter hole and the interface process and other factors will affect the filtering effect of the filter cloth, but also lead to filter cloth clogging; so the new dimension filter cloth Co., Ltd. Depending on the muddy sludge handled by the customer, a suitable filter cloth material is selected and recommended.
2. The use of polyester material, this material is generally applicable to acidic filter, but also high temperature, tensile strength, vertical and horizontal stability, wear resistance second only to nylon, sludge filter selection should consider what It is currently the most widely used filter cloth material on the market;
3. Polypropylene filter cloth, this material is better acid and alkali, the general use of the temperature below 90 degrees, the disadvantage is that the tensile strength is not high. Under normal circumstances, most businesses will not choose it, but there are some special industries will choose, this product is high alkali resistance.
4, The above reasons are all manifestations, but the fundamental reason causing the clogging of the filter cloth lies in that the water content of the mud cake after dewatering is still high, which still has the stickiness, resulting in the clogging of the filter cloth. The sludge treatment efficiency is low. The new dimension filter cloth ultra-high pressure sludge filter in the sludge dewatering the reason why there will be no clogging filter cloth, largely sludge dewatering moisture content decreased below 60%, the formation of non-stick dry mud cake , Will not be glued to the filter cloth, but in the cake automatically unloading device under the action, simply neat off from the filter cloth.
Clogged filter cloth will seriously affect the filter effect of sludge filter and its efficiency, through the above description, the filter cloth clogged filter cloth is due to the filter hole, filter cloth material, filter material also Temperature, sludge filter itself dehydration ability, understand these reasons, according to the filter material to choose the material of the filter cloth and the size of the filter. From the source in a timely manner to prevent.
