SINOU Carbon Neutrality Wastewater Treatment System is a containerized integrated neutralization and recycling unit tailor-made for concrete batching plant alkaline wastewater, perfectly supporting the full-set residual concrete recovery & aggregate regeneration system required by the Saudi tender.
Concrete plant wastewater features ultra-high alkalinity (raw pH 12.5–13) and heavy suspended desert fine silt (50–100μm ultra-fine sand). This wastewater system uses food-grade liquid CO₂ carbonation neutralization technology, replacing traditional caustic soda dosing. It stabilizes effluent pH to 6.5–8.5 for direct production reuse, eliminates secondary pollution, mitigates silt deposition, resolves pump blockage, and lifts long-term system availability above 95%.
The complete skid-mounted water circulation system consists of these core assemblies:
● Liquid CO₂ storage tank & vaporizer unit
● Pressure reducing & gas delivery power plant
● Two-stage cascade reaction reactor
● High-pressure plunger feed pump set
● PH online transmitter & real-time monitoring probe
● Radar level gauge for pool liquid level interlock control
● PLC+MCC electronic automatic control cabinet, HMI touch screen & mobile APP remote control
● Pressure safety control system & gas-liquid solenoid valves
● Solid-liquid filter press / slurry filter for silt dewatering
● Supporting raw water tank, transition buffer tank, clean water reuse tank & pipeline framework
Highly alkaline wastewater containing massive ultra-fine desert silt flows from the concrete recovery line into the raw water tank. Large flocs and coarse solids are pre-intercepted; soluble silt-laden wastewater is pumped to the reaction module via the plunger feed pump.
Liquid CO₂ is vaporized into gaseous CO₂, pressure-regulated and injected into the sealed two-stage reactor. Alkaline wastewater is atomized inside the tower and fully mixed with CO₂ gas: High-alkali calcium hydroxide from cement & desert sand reacts to form insoluble calcium carbonate silt, lowering pH steadily. Real-time PH probes feed signals back to the PLC to auto-adjust CO₂ gas flow for precise pH stabilization.
Neutralized water overflows into the transition tank; precipitated carbonate-sand slurry sinks to the tank bottom. Periodically, concentrated slurry is pumped into the solid-liquid filter press unit. Filter cake (mixed sand & carbonate sludge) is dewatered for solid waste disposal; filtrate flows back to the raw water tank for reprocessing.
Supernatant clarified water from the transition tank flows into the clean water pool. Treated water meets concrete mixing reuse standards, pumped back to mixer truck washing, aggregate washing, and batching production lines to realize 100% water closed-loop circulation.
Radar level gauges monitor liquid levels across all pools; PH transmitters, gas pressure sensors, pump running signals interlock with the PLC system to auto-adjust pump speed, CO₂ flow, and slurry discharge cycles. Manual/automatic dual operation modes are available, with remote mobile APP monitoring and fault alarm.
No alkaline chemical additives like sodium hydroxide. CO₂ carbonation creates stable carbonate precipitates, avoids over-dosing pH fluctuation, cuts chemical consumption cost.
Two-stage reactor with turbulent mixing prevents ultra-fine sand adhesion to tank walls; transition tank adopts sloped anti-silt bottom structure + timed slurry pumping cycle.
Pre-filter screens before pump suction ports + variable-frequency plunger pump with large flow passages; neutralization flocculation aggregates tiny desert sand particles into larger settleable flocs, reducing fine particle abrasion and blockage of pump impellers and pipeline elbows.
Robust corrosion-resistant material construction for all wetted parts (anti-alkali, anti-silt abrasion); automated self-clean slurry discharge cycles reduce manual maintenance frequency drastically vs conventional wastewater systems. Long service life with minimal downtime.
Standard processing water flow 30–60m³/h. Gas flow adjustable 50–500m³/h to cope with fluctuating peak wastewater output from 3 sets of 150m³/h mixing plants.
PLC+HMI local control + mobile APP remote real-time monitoring, fault self-diagnosis and alarm.

It forms a complete closed-loop treatment line for residual concrete and washing wastewater of concrete batching plants. The whole set of equipment adopts unified PLC central control, realizing synchronous linkage operation and easy overall management.
A: Our standard wastewater system has a processing capacity ranging from 30 m³/h to 60 m³/h, which fully satisfies the water treatment demand of large concrete batching plants with multiple production lines. We also support customized flow design according to actual daily wastewater output to match different plant scales.
A: The system is designed for 3-phase, 380V, 60Hz power supply, which is completely compatible with the synchronous generator power supply commonly used in Saudi Arabia and other Gulf regions. The electrical components have been optimized for unstable voltage of generator sets to ensure stable operation.
A: We adopt a combined process of multi-stage filtration, coagulation and gravity sedimentation. Firstly, multi-layer precision filter screens intercept most fine sand; then stirring equipment mixes wastewater with coagulant to gather scattered micro-particles into large flocs.
After natural sedimentation in the horizontal sedimentation tank, the residual tiny particles are trapped by the front-end filter of the pump. Finally, all sludge containing fine sand is transported to the filter press for deep dewatering, realizing full disposal of particles below 100μm without leakage.
A: Combined with the actual working conditions of desert fine sand and SINOU’s mature technical route, we cancel hydrocyclone and inclined tube structures. The horizontal sedimentation tank with large volume is equipped with full-time stirring devices, which extends the hydraulic retention time and ensures sufficient settlement of ultra-fine sand.
This design simplifies the equipment structure, reduces failure points and daily maintenance workload, and is more suitable for long-term continuous operation in harsh desert environments.
A: We take multiple anti-sediment measures. All water tanks adopt sloped cone-bottom structure without dead corners, and the inner wall is coated with anti-stick and wear-resistant coating. Every tank is equipped with dedicated stirring devices to keep the water body flowing dynamically all the time.
Meanwhile, the system is fitted with liquid mud level monitors and automatic mud discharge valves, which regularly discharge sludge to the filter press. It fundamentally avoids long-term deposition and compaction of sediment.
A: There are multiple protection measures for pump anti-clogging. First, multi-stage filters are installed at the pump inlet to block sundries and agglomerated mud.
Second, we use SINOU’s self-developed hydraulic ceramic plunger pump with large flow passages and excellent anti-abrasion performance, which is not easy to be stuck by fine particles.
In addition, the stirring device will run in advance before the pump starts to stir up the bottom sediment, preventing instantaneous mud suction and blockage. The system also has overload and stall protection to stop the machine automatically in case of abnormal conditions.
A: All flow-passing parts in contact with sewage and fine sand are made of high wear-resistant materials. The inner wall of pipelines and tanks is treated with anti-abrasion coating.
Combined with the pre-filtering process, the content of free fine sand in the water is greatly reduced, which effectively lowers the wear rate of the whole system and extends the service life.
A: Stirring systems are standard configurations for all tanks and pools. The stirrers in the water collection tank and concentration tank prevent fine sand from settling and compacting; the stirrers in the reaction tank ensure the full mixing of carbon dioxide, coagulant and wastewater, so as to guarantee the neutralization and flocculation effect.
All stirring devices are interlocked with pumps and mud discharge valves to realize fully automatic operation.
A: The filter press is the core equipment for terminal sludge disposal. It can squeeze high-concentration mud containing ultra-fine sand into dry mud cakes, realizing thorough solid-liquid separation. The filtrate flows back to the front-end pool for recycling, achieving zero sewage discharge.
The fully automatic filter press supports unattended operation, with large sludge processing capacity and stable performance, which is the optimal choice for continuous production of mixing plants.
A: This system adopts carbon dioxide neutralization technology, which is our core carbon neutrality solution. The alkaline substances in cement wastewater react with CO₂ to generate water and harmless carbonate sediment.
No caustic soda and other chemical agents are added during the whole process, so there is no secondary pollution, which meets local environmental protection standards in the Gulf region.
A: The raw alkaline wastewater from mixing plants has a pH value of 12.5~13. After CO₂ neutralization treatment, the pH of the effluent is stably controlled between 6.5 and 8.5.
The recycled water fully meets the water quality standards for concrete batching and mixer truck cleaning, and can be directly reused in the production link.
A: The overall maintenance work is simple. Daily work mainly includes inspecting the operating status of pumps and stirrers, checking filter screens and conducting backwashing, and observing liquid level and pH data.
Weekly and monthly maintenance focuses on lubrication, instrument calibration and bolt fastening. We have formulated a complete hierarchical maintenance plan, and the operation and maintenance personnel can get started quickly after professional training.
A: We adopt five-level maintenance management: daily inspection, weekly routine maintenance, monthly partial overhaul, quarterly component inspection and annual full-system overhaul. The wearing parts such as filter screens, filter cloths, pump seals and stirring blades have clear replacement cycles, which can effectively ensure the overall operation rate of the equipment above 95%.
A: The whole set of wastewater system enjoys a 3-year full warranty . We provide overseas on-site installation guidance, equipment commissioning and professional operator training. A complete list of spare parts for two years of operation is provided together with the equipment, and we guarantee fast delivery of spare parts to the Gulf region.
A: Yes. The whole system adopts PLC + HMI intelligent control, with full automatic linkage of stirring, water pumping, mud discharging and filter pressing. It supports real-time remote monitoring and fault alarm, realizing 24-hour unattended continuous operation, which greatly saves labor costs for the plant.
A: Firstly, it targets the pain points of desert ultra-fine sand, with perfect anti-sedimentation and anti-clogging design and higher equipment operation rate.
Secondly, carbon dioxide neutralization technology saves chemical costs and is more environmentally friendly.
Thirdly, the equipment structure is simplified without redundant units such as hydrocyclones, so the failure rate and long-term maintenance cost are lower.
In addition, the compact layout is convenient for transportation and on-site installation.

SINOU spray column, also known as empty tower spray scrubber, abandons the traditional internal filler layout and adopts hollow tower body + multi-layer swirling atomizing nozzle innovative structure. This gas purification tower is independently developed to solve cement dust, alkaline flue gas blockage troubles generated during the CO₂ neutralization reaction of concrete batching plant wastewater.
When the waste gas containing fine desert sand dust enters the tower, circulating neutralization liquid forms dense mist to absorb alkaline components and trap dust particles. The purified gas reaches emission standards, while the waste liquid flows back to the water treatment station for cyclic reuse.
The whole set can form a complete gas-water closed-loop treatment system when matched with HDPE Slurry Pipe, Chamber Filter Press and Heavy Duty Mixer Truck Washing Machine.
Many clients wonder how the spray column achieves high purification efficiency without internal fillers, its core counter-current process has 6 continuous operation steps:
(1) Dust-containing alkaline flue gas enters from the tangential air inlet at the tower bottom, and the rotating air flow initially separates large cement particles to reduce nozzle clogging risk
(2) The gas flows upward along the hollow tower cavity without filler obstruction, with extremely low wind resistance loss
(3) Multi-layer swirl atomizing nozzles at the upper part of the tower spray neutralizing liquid downwards to form countless tiny liquid droplets
(4) Upward flue gas and downward mist fully collide and contact, alkaline substances chemically react with neutral liquid, and fine dust is wrapped and captured by droplets
(5) The purified clean gas passes through a folded plate mist eliminator at the tower top to intercept entrained water mist before being discharged
(6) The mixed waste liquid carrying dust flows into the bottom liquid storage tank, and the circulation pump sends it back to the Carbon Neutrality Waste Water System through HDPE Slurry Pipe for sedimentation and re-spraying The PLC system links the PH detector to automatically adjust the spray liquid supply volume according to flue gas alkalinity, requiring no manual real-time adjustment.
All parts of SINOU spray column adopt split flange connection design, convenient for sea freight transportation and on-site assembly; all wetted components are anti-corrosion treated to adapt long-term alkaline dust working conditions:
(1) Main Split Tower Body: Optional PP, FRP or 304 stainless steel materials, segmented flange splicing to reduce single-piece transportation volume
(2) Tangential Dust Separation Air Inlet: Spiral air intake structure to pre-settle large cement slag and avoid direct impact on nozzles
(3) Multi-layer Swirl Atomization Nozzle Group: Large-diameter flow channel design, not easy to be blocked by 100μm desert fine sand
(4) V-type Folded Plate Mist Eliminator: Installed at the tower outlet to eliminate liquid mist entrainment and prevent secondary water mist emission
(5) Integrated Bottom Liquid Storage Chamber: Equipped liquid level transmitter to realize pump start-stop linkage control
(6) Side Inspection Manholes & Transparent Observation Windows: Reserve maintenance ports for regular nozzle cleaning without disassembling the whole tower
(7) External Independent Circulation Pump Unit: Separated layout outside the tower, easy maintenance and pump replacement
(1) Filler-free Hollow Tower Core Design: Fundamentally eliminate the common failure that traditional filled towers are blocked by cement fine sand, greatly extend the maintenance cycle
(2) Swirl Large Flow Nozzles: Compared with ordinary straight nozzles, the anti-clogging performance is increased by more than 70%, adapting Middle East desert sand working conditions
(3) Multiple Corrosion-resistant Material Options: Flexible matching tower materials according to different alkalinity of flue gas, long service life under high alkali environment
(4) Low Wind Resistance Energy-saving Structure: No filler to block airflow, fan power consumption reduced by nearly 30% compared with filled towers
(5) Modular Split Transportation: The tower is divided into multiple small sections, which can be loaded into standard containers to cut ocean freight costs
(6) Intelligent Linked Spraying System: Real-time PH signal feedback automatically adjusts liquid supply to save neutralizer consumption
(7) Full Line Matching Compatibility: Can be seamlessly connected with Chamber Filter Press and Heavy Duty Mixer Truck Washing Machine to build integrated mixing plant environmental protection equipment set

The realization of carbon neutrality mainly relies on four aspects: source emission reduction, end of pipe absorption, market regulation, and policy support. The country has issued multiple heavyweight documents to clarify the path.
Regarding the carbon neutrality technology for mixing plant wastewater treatment, I conducted an investigation in Australia in 2008 based on the actual situation of domestic mixing plants; The domestic reuse of these deactivated wastewater seriously affects the stability and reliability of concrete products. Meanwhile, sewage causes damage to groundwater resources and the environment. Moreover, high concentration alkaline wastewater poses a series of problems such as severe corrosion and blockage to the production equipment of the mixing plant.
In order to further strengthen the control of dust pollution and improve air quality, the District Housing and Urban-Rural Development Committee has vigorously promoted the airtight upgrade and transformation of concrete mixing plants, and carried out special … inspections on the implementation of green production of ready-mixed concrete mixing plants, actively promoting the development of environmental quality in the jurisdiction, and assisting the development of environmental protection.
In modern industrial filtration systems, efficiency, stability, and pressure control determine the overall performance of solid-liquid separation. A piston pump for filter press plays a crucial role in delivering consistent high-pressure feeding, ensuring optimal cake formation and reduced moisture content. This article explores its working principles, advantages, applications, selection guidelines, maintenance strategies, and real-world industrial value.
