Dehydrated sludge in China grows more than 450 times

Yang Xiangping, former general manager of Beijing Drainage Group and currently director of the Water Association's Water Drainage Committee, talked about the current status of sludge disposal in China. In the past 30 years of reform and opening up, urban construction has grown rapidly. The number of cities has increased from 193 to 664. The number of sewage treatment plants has increased from 37 to more than 2,800. The sewage treatment capacity has increased from 640,000 tons to 128.67 million tons per day. The national urban sewage treatment rate has reached 73%. The production of dewatered sludge in China has increased from 150 tons per day in 1978 to 68,000 tons per day in 2010, an increase of more than 450 times. The treatment and disposal of sludge should be based on local conditions. For large cities, it can be promoted and dried. For example, the Shidongkou project promotes centralized disposal of medium-sized cities. For small-scale sewage treatment plants to be constructed on a large scale, small-scale compost facilities should be promoted.

Evaporation & Concentration Equipment Series

The Evaporation & Concentration Equipment Series is a range of high-quality equipment designed to meet the needs of various industries. These equipment are used for the separation of liquid and solid components in a mixture by evaporation and concentration. The series includes a wide range of products such as evaporators, distillation units, crystallizers, and concentrators.


The Evaporation & Concentration Equipment Series is widely used in the food and beverage industry, pharmaceuticals, chemical processing, and many other industries. The equipment is designed to handle a variety of liquids and solids, making it ideal for use in many different applications.


The series includes a variety of evaporators, including falling film evaporators, rising film evaporators, forced circulation evaporators, and wiped film evaporators. Each type of evaporator is designed to meet specific requirements and can be customized to suit individual needs.


Distillation units are also part of the Evaporation & Concentration Equipment Series. These units are used to separate liquids based on their boiling points. They are commonly used in the chemical industry and are essential for the production of high-purity chemicals.


Crystallizers are another important component of the series. They are used to separate solids from liquids by crystallizing the solid component. Crystallizers are commonly used in the production of chemicals, pharmaceuticals, and food products.


Concentrators are also part of the series. They are used to concentrate liquids by removing water or other solvents. Concentrators are commonly used in the food and beverage industry for the production of juices, syrups, and other concentrated products.


In conclusion, the Evaporation & Concentration Equipment Series is an essential component of many industries.
