Covering multi-level processing requirements according to device specifications: Low temperature evaporators on the market have clear gradients in processing capacity, suitable for different scale requirements. The processing capacity of small equipment is as low as 100 liters per day, suitable for the treatment of small amounts of experimental wastewater in laboratories and small research and development institutions; Small and medium-sized equipment is the mainstream, with a daily processing capacity concentrated between 0.5-20 tons, suitable for the daily needs of small and medium-sized factories. For example, Qingdao Shuiqing Muhua HP-C equipment can process 20 tons per day, suitable for nickel containing wastewater treatment in electroplating enterprises, and Yantai Zhenghai Magnetic Materials Company can process 3 tons of cutting waste liquid per day. Large customized equipment has stronger processing capabilities. Weihai Runlan's IVECDEST S-VE system can handle up to 100 tons/day, and a pharmaceutical company even uses equipment that can process up to 30 tons per day for the concentration of traditional Chinese medicine extracts. When multiple units are linked, it can also meet the centralized processing needs of large-scale projects such as surface treatment industrial parks.
Customized design breaks through the limitations of special wastewater treatment: For difficult to treat wastewater such as high salt and high viscosity, customized equipment maintains treatment capacity through process upgrades. For example, wastewater from a certain raw material pharmaceutical company containing 25% sodium sulfate is prone to scaling. Customized equipment combined with scraper evaporation crystallization technology not only avoids downtime for maintenance, but also ensures stable treatment capacity; Weihai Runlan's VESALT scraper system can process concentrated liquids into powdery solids and control the moisture content below 20% when treating high viscosity wastewater. A customized HP equipment with a daily processing capacity of 10 tons by a certain enterprise in Zhejiang has a fluoride removal rate of over 99.8% and reduced energy consumption by 45%. It can be seen that the customized equipment not only ensures the processing capacity but also considers the processing effect.
The impact of water quality on treatment capacity and corresponding solutions: Simple water quality wastewater can enable equipment to stably operate at its rated capacity. For example, when treating ordinary cutting fluid wastewater, the equipment can achieve a concentration reduction rate of over 90%. The complex composition of wastewater can easily reduce treatment efficiency, and this equipment has a dedicated response design. For example, when treating emulsion wastewater with high COD values, a condensate deep purification module can be used to achieve a COD removal rate of over 85% while maintaining daily processing capacity; When dealing with high concentration wastewater such as leachate from garbage, a combination of "pretreatment+low-temperature evaporation" scheme is adopted, and the 20 tons/day leachate treatment demand of a hazardous waste disposal unit is also met.
Efficient concentration and energy consumption advantages enhance comprehensive processing efficiency: The high concentration characteristics of low-temperature evaporators further amplify the actual processing value. Most devices can achieve a 90% -95% reduction in waste liquid concentration. When Qingdao Shuiqing Muhua's equipment is used to treat electroplating wastewater, the volume of concentrated solution is reduced by 90%, and the distilled water reuse rate of Weihai Runlan's equipment reaches 95%. In terms of energy consumption, treating 1 ton of wastewater consumes about 130-160 kWh of electricity, and the cost of treating 1 cubic meter of water during the valley electricity price period is only 48-60 yuan. Low energy consumption supporting equipment can operate continuously for a long time, avoiding being forced to land loads due to high costs, ensuring long-term stable treatment capacity, and making high-capacity operation economical.
