Deep dewatering of sludge: How to choose the sludge filter press?

2022-11-14

Introduction

In Sludge Treatment, the selection of sludge treatment equipment directly affects the sludge treatment effect, so how to choose the sludge Filter Press? Shenzhen Hongfa Environmental Protection Equipment Co., LTD., a supplier of sludge treatment equipment, summarized the following three evaluation factors.

Degree of sludge treatment

Nowadays, the relevant environmental laws and regulations stipulate that the sludge can be landfill or resource utilization only when the moisture content is below 60%. Therefore, when selecting the sludge Filter press, we must ensure that the moisture content of the sludge treated by the sludge treatment equipment reaches the standard. This is also the primary consideration for the selection of sludge Filter press. At present, there are both ordinary sludge filter press and ultra-high pressure sludge deep dewatering filter press on the market, such as ShenHongfa sludge presser, etc. For the long-term consideration of sludge disposal engineering, it is recommended to choose sludge deep dewatering equipment.

Sludge treatment efficiency

There are many Sewage Treatment plants or industrial enterprises, because the sludge treatment equipment processing capacity can not reach the amount of sludge production, often resulting in sludge accumulation situation. The sludge treatment efficiency of the same type of sludge filter press produced by different sludge treatment equipment suppliers is very different. For example, the sludge treatment capacity of a 500 square Diaphragm filter press used by an enterprise is 150 square, and the same sludge treatment effect can be achieved with the deep Hongfa sludge dryer.

Automation degree of sludge Filter Press Operation

Automatic sludge filter press saves manual operation, also ensures the accuracy of equipment operation, and can achieve good sludge treatment effect stably. Instead of automatic sludge filter press in operation, it is necessary to manually unload mud cake, clean the press cloth, etc., and the sludge treatment cycle is not easy to control. Automatic sludge filter press will be more popular in the future, is a development trend of the sludge treatment industry, in the purchase, can be selected according to their own needs.

Sludge treatment cost

A sludge disposal project, sludge filter press and other sludge treatment equipment and sludge treatment cost has become the main investment, therefore, the selection of sludge filter press not only depends on the sludge filter press itself, but also consider the cost of sludge treatment with it. For example, using ShenHongfa sludge presser to treat a ton of municipal sludge with 80% moisture content needs 40-60 yuan, while using plate Frame Filter Press to treat the same sludge needs 100-180 yuan. For large-scale sludge disposal projects with a daily sludge treatment capacity of more than 100 tons, the annual sludge treatment cost will be millions of differences.
