Xinxiang, Henan, October 2023 - With the increasing demand for efficient use of water resources and environmental protection in the coal chemical industry, Henan Xinxiang Lifelte Filter Co., LTD. (hereinafter referred to as "Lifelte") provides breakthrough solutions for desalted water and sewage treatment in the industry with its self-developed "high-precision security filter system". Help enterprises to achieve the dual goals of water conservation and consumption reduction and green transformation. Recently, the company's successful application cases in a number of coal chemical projects have aroused widespread concern in the industry.
Coal chemical water treatment pain point: traditional technology is difficult to take into account the efficiency and cost of coal chemical production process, desalted water preparation and sewage purification is the key link. Traditional filtration equipment often faces the following challenges: first, the water quality is complex, the salt content is high, the suspended matter is more, easily lead to equipment blockage or corrosion; Second, the processing efficiency is low, frequent replacement of filter element increases operating costs; Third, the degree of automation is insufficient, and manual maintenance is time-consuming and labor-intensive. In response to these pain points, Lifeldt filter innovated and developed a customized security filtration system, with "high precision + corrosion resistance + intelligence" as the core, reshaping the industry's water treatment standards.
High-precision filtration, "zero tolerance" of impurities: 304/316L stainless steel material and imported folding filter element, filtration accuracy of up to 0.5 microns, effectively intercept suspended particles, colloids and microorganisms, provide "pre-protection" for core equipment such as reverse osmosis membrane, and extend its service life by more than 30%. Corrosion resistant design, adapt to extreme conditions: PVDF coating and double seal structure inside the equipment, can withstand acid and alkali corrosion and high temperature and high pressure environment (maximum temperature of 120℃, pressure of 2.5MPa), in the coal chemical industry high salt, high chloride ion media to achieve stable operation. Intelligent monitoring, operation and maintenance cost halved: integrated pressure difference sensor, automatic blowdown valve and remote control system, real-time monitoring of filtration status, when the pressure difference exceeds the set value (such as 0.8MPa) automatically start the backwash procedure, reduce manual intervention by 50%, filter replacement cycle extended to 2-3 times that of traditional equipment.
The filtration efficiency is increased by 40% : the SDI value (pollution index) of the system effluent is stabilized below 3, and the recovery rate of the reverse osmosis membrane is increased to 75%; Operation and maintenance costs reduced by 35% : the annual filter replacement cost was reduced from 280,000 yuan to 180,000 yuan, and the frequency of manual inspection was reduced from 3 times a day to 1 time a week; The environmental benefits are highlighted: the sewage reuse rate has increased from 60% to 85%, saving about 120,000 tons of water per year, and reducing the cost of wastewater discharge by 1.5 million yuan. "Liffert's equipment not only solves our technical bottleneck, but also brings real economic benefits." Mr. Wang, the manager of the equipment department of the enterprise, said, "The system recovers the investment cost within one year of operation, and the intelligent management also lets us bid farewell to the trouble of 'passive maintenance'."
Li Jianguo, chairman of Lifelte Filter, pointed out that the coal chemical industry is accelerating towards the goal of "zero emission", and water treatment equipment needs to be developed in the direction of "high efficiency, modularity and integration". At present, the company is cooperating with the Institute of Process Engineering of the Chinese Academy of Sciences to develop a new generation of "membrane method + filtration" coupling system, which is expected to reduce the energy consumption of desalination by 20% and increase the sewage treatment compliance rate to 99.5%. "We hope to provide the industry with smarter and more environmentally friendly solutions through continuous innovation to help the coal chemical industry achieve sustainable development."
