Condition: used, Year of construction: 2007, Prominent water treatment plant, consisting of: 1. Softening: The raw water is fed into the double softener. Only one bottle is ever in operation and the other is in regeneration or stand-by. In the softener, calcium and magnesium are replaced by sodium. The system has a volume counter that switches to the other bottle when the preset quantity is reached. Regeneration takes place with saline solution from the brine tank. The value at the outlet is 0°dH. 2. reverse osmosis: Reverse osmosis fills the permeate tank with demineralised water, so-called permeate. Depending on the raw water quality, water temperature, condition of the membrane and correct setting, different conductance values and operating pressures result. The following flow rates are set during commissioning: Permeate 600 l/h, concentrate 200 l/h, corresponding to a yield of 75%. 3. permeate tank and ozonisation: The unpressurised 500 l permeate tank has an adjustable level control. For treatment with ozone, the water in the permeate tank is circulated via an adjustable ozone feed point. The ozone is generated from air in the ozone generation system by means of a silent electrical discharge and is available as an ozone-air mixture. The air and the undissolved ozone rise upwards in the permeate tank and are discharged via the residual ozone destroyer. A redox potential and ozone measurement is carried out after the centrifugal pump for monitoring purposes. The ozone dosage is set via the touch panel. You can choose between regulation via the redox potential or the ozone concentration.

Condition: used, Year of construction: 1994, Three-stage water degassing system for water degassing and CO2 impregnation. The raw water enters the first degassing tank through an injector nozzle.

MINGYUAN provides complete aggregate crushing and screening solutions for quarries, mining, construction, and infrastructure projects, ensuring efficient material processing and consistent output. General Introduction The MINGYUAN sand and gravel production line combines advanced crushing, screening, washing, and conveying equipment to process raw materials such as limestone, granite, basalt, river stone, and quartz into various sizes of construction sand and gravel aggregates. The plant typically includes jaw crushers, impact crushers, cone crushers, vibrating screens, sand washers, belt conveyors, and dust collectors, forming a complete and automated production system. It is widely used in road construction, concrete batching plants, building materials, and hydropower projects. Capacity range: 30–1000 tons per hour (customizable) Feed size: ≤800 mm depending on crusher type Output size: 0–5 mm (sand), 5–10 mm, 10–20 mm, 20–40 mm (gravel) Main equipment: Jaw crusher (PE/PEX series), cone crusher, impact crusher, VSI sand maker, vibrating feeder, vibrating screen, sand washing machine, belt conveyor, and control system Power configuration: Electric or diesel-driven options available Automation: PLC control with real-time monitoring and adjustable output ratio MINGYUAN Heavy Industrial Equipment Co., Ltd. provides complete sand and gravel production solutions with reliable performance, competitive price, and professional after-sales service for global customers in the mining, construction, and cement industries. 2. Crushing and Screening: - The extracted raw materials often need to go through crushing and screening processes to reduce their size and separate them into different grades. - Crushers break down large rocks into smaller pieces, and screens sort the particles based on size. 3. Washing: - Washing is a common process to remove impurities such as clay, silt, and dust from the raw materials. This is particularly important for sand and gravel used in construction. 4. Grading and Sorting: - After washing, the materials may go through grading and sorting processes to separate them into different sizes and qualities. 5. Storage and Stockpiling: Iodpfeq Nia Iex Acheba - Processed materials are often stored in stockpiles for further use. Adequate storage facilities are necessary to manage different grades of materials. 6. Conveying and Transportation: - Conveyor systems are used to transport materials between different stages of the production process. Transportation methods, such as trucks or conveyor belts, are used to move the final products to distribution points.
