In the process of treating sewage and sludge, sludge dehydrating agent is a very important link. A suitable sludge dewatering agent can improve the dewatering efficiency, reduce energy consumption and reduce environmental pollution. So, how to choose the right sludge dehydrant for you? This article will answer you from the following aspects:

1. Understand sludge properties

Before choosing a sludge dehydrator, it is necessary to first understand the properties of the sludge. Sludge is mainly composed of water, organic matter and inorganic matter, and different sludge components need to use different dehydrating agents. In addition, it is also necessary to consider the composition of the sludge, moisture content, organic matter content, temperature, pH value and other factors will affect the dehydration effect.

2. Dehydrating equipment

Different dehydrating equipment has different requirements for dehydrating agents. For example, belt filter presses, centrifuges and other equipment need to use polyacrylamide with strong shear resistance, and plate and frame filter presses need to be used with inorganic flocculants.

3. Focus on product performance

In the selection of sludge dehydrating agent, it is necessary to pay attention to its performance indicators, such as desliming rate, energy consumption, COD removal rate, etc. These indicators directly affect the effectiveness and cost of dehydration. In general, the higher the performance index, the more suitable for high-concentration, difficult to dehydrate sludge. Therefore, the choice should be based on their actual needs to weigh.

4. Pay attention to environmental protection requirements

When selecting sludge dehydrating agent, it is necessary to pay attention to whether it contains harmful substances and whether it is easy to biodegrade.

5. Price factor

Of course, the price is also one of the factors that need to be considered when choosing a sludge dehydrator. On the premise of meeting the performance requirements, you can choose products with higher cost performance. However, we should pay attention to avoid blindly pursuing low prices, resulting in poor product quality or short service life.
