Alkaline Wastewater Treatment System for Concrete Batching Plant

As a professional China manufacturer, Sinou has independently developed this Alkaline Wastewater Treatment System for Concrete Batching Plant. Our factory uses corrosion-resistant materials and automatic control technology to ensure stable neutralization and purification of high-alkaline sewage.

As a reliable supplier, we provide customized solutions and comprehensive after-sales services to meet the diverse needs of global customers.

Specifications & Parameters

General summary: This high-efficiency alkaline wastewater treatment system is designed for concrete batching plants, with adjustable capacity, precise pH control, anti-corrosion structure and automatic operation to meet different scales of concrete wastewater treatment needs.

1. The system offers a treatment capacity range of 50–500 cubic meters per hour and can be customized according to customer demands to adapt to different scales of batching plants and different sewage volumes.

2. The pH adjustment range is 6.0 to 8.0 and is fully adjustable during operation to ensure stable effluent quality meeting national and international discharge standards.

3. The main equipment can be made of anti-corrosion carbon steel, SS304 stainless steel, or engineering plastic for strong corrosion resistance, suitable for high-alkaline concrete wastewater with long-term chemical impact.

4. The control system adopts PLC automatic control with manual backup mode to ensure stable operation under any working condition and to prevent system shutdown due to control failure.

5. The neutralization efficiency of the whole system is higher than 99%, ensuring stable effluent quality with low residual alkalinity and suspended solids, meeting industrial reuse requirements.

6. The equipment can be configured with modular expansion units, including sludge treatment and deep filtration modules, to meet different environmental compliance standards and customer needs

How the System Works

Alkaline Wastewater Treatment System for Concrete Batching Plant adopts a multi-stage neutralization and purification process, from pH adjustment to coagulation, precipitation and filtration, to complete the treatment of concrete wastewater step by step.

1. Concrete batching plant wastewater flows into the reaction tank, where pH sensors trigger automatic dosing of neutralizers to adjust alkalinity to a safe range.

2. After neutralization, the water undergoes coagulation to aggregate fine cement particles and suspended solids into large flocs for easy removal.

3. The flocculated water enters the sedimentation tank, where solid impurities settle at the bottom, and clear water flows to the next stage.

4. The supernatant passes through a multi-stage filtration system to remove residual fine particles and turbidity, ensuring the water is clear and clean.

5. Finally, the treated water is either discharged or recycled for concrete production, equipment washing, and site watering.

6. The sludge collected during the process can be treated by a filter press and then reused or disposed of in accordance with environmental regulations.

Core Product Advantages

1. High-efficiency Neutralization: Automatically adjusts pH levels of concrete wastewater to meet discharge standards, with 99% neutralization efficiency, reducing the risk of environmental penalties.

2. Water Recycling Function: Treated water can be reused for concrete production, reducing water costs by up to 40% and eliminating the need for frequent tap water purchases.

3. Low Energy Consumption: The optimized design reduces power consumption by 30% compared with traditional equipment, lowering operating costs and carbon emissions.

4. Anti-corrosion and Durable: The main parts are made of anti-corrosion materials, with a service life of more than 10 years under normal working conditions, reducing replacement frequency.

5. Easy Maintenance: The modular structure allows quick replacement of consumables, with minimal daily maintenance requirements, saving labor and time costs.

6. Flexible Expansion: Can be matched with sludge filter presses, sand and gravel separators, and other equipment to form a complete closed-loop water treatment system
