During our communication with numerous customers, we discovered that there are some common misunderstandings about the sludge dewatering agents among them. As a responsible supplier, Works Co., Ltd. is clarifying these issues here to help everyone establish a scientific expectation.

Misconception 1: "As long as special treatment drugs are added, any filter press can dry out the sludge."

The truth: The chemicals can only improve the sludge's dewatering performance, but they cannot break through the limits of the physical equipment. If the pressure of the filter press is insufficient, the filter cloth is aged and clogged, or the pump's head pressure is not enough, even the best chemicals will not be able to produce low moisture content sludge cakes. The chemicals and the equipment have a "complementary" relationship, rather than an "alternative" one.

Misconception 2: "The lower the moisture content, the better. It must be reduced to below 40%."

The truth: The moisture content is not necessarily lower is better. Economic considerations must also be taken into account. It is relatively easy to reduce the moisture content from 60% to 50%, but reducing it from 50% to 40% may require several times the amount of chemical consumption and energy input. For most landfill and co-incineration projects, the national standards usually require a moisture content below 60%. Blindly pursuing the ultimate low moisture content may lead to a sharp increase in processing costs, which is not worth it. One should find the "most cost-effective" balance point based on the requirements of the final disposal method.

Misconception 3: "One type of agent can be used for all types of sludge."

The truth: The composition of sludge is extremely complex. The sludge from municipal wastewater treatment plants is vastly different in nature from that of electroplating plants, paper mills, and pharmaceutical factories. Even for the same factory, the sludge properties will fluctuate depending on different seasons and production loads. Therefore, there is no such thing as "one solution fits all".

Works insists on providing customized pilot testing services for each client to ensure the targeted nature of the solutions.

We advocate rational pollution control and reject excessive marketing. Only by correctly understanding the complexity of sludge treatment can we find the most suitable solution.
