09-08-2026 03:28 AM CET | Energy & Environment Press release from: ABNewswire Sinou's Concrete Batching Plant Carbon Neutral Wastewater Treatment System uses CO-carbonation technology to treat high-alkaline wastewater. Integrating ceramic plunger pumps, filter presses, carbonation reactors and PLC control, it supports pH neutralization, solid-liquid separation and reclaimed-water reuse while reducing chemical reliance and operating workload. JIAXING, China - September 7, 2026 - The ready-mixed concrete industry consumes large volumes of water in concrete production, mixer-truck washing, mixer cleaning, and site-floor rinsing. Statistically, every cubic meter of concrete requires approximately 0.18 m of mixing water and generates around 0.03 m of wastewater. For concrete batching plants, the treatment and reuse of highly alkaline wastewater remain important environmental and operational concerns. Sinou Concrete Batching Plant Carbon Neutral Wastewater Treatment System [ https://www.senyoubeton.com/carbon-neutral-wastewater-treatment-system-for-concrete-batching-plant.html ] is a CO-carbonation solution that neutralizes alkaline wastewater and supports reclaimed-water reuse at concrete batching plants. Wastewater from batching plants typically has a pH value above 12.5 and contains cement-derived fine solids, dissolved alkalis, calcium ions, and magnesium ions. Direct discharge can create risks for soil and groundwater. When reused without suitable treatment, highly alkaline wastewater may affect concrete performance, including alkali-aggregate reaction risk, admixture compatibility, slump loss, and setting behavior. Conventional neutralization methods often rely on mineral acids such as hydrochloric acid or sulfuric acid. In addition to the handling requirements associated with corrosive chemicals, acid neutralization can introduce sulfate and chloride salts into the water, making subsequent reuse more complicated. Zhejiang Sinou Environmental Protection Equipment Co., Ltd. [ https://www.senyoubeton.com/ ] has developed a fully automated CO-carbonation neutralization system for high-alkaline batching-plant wastewater. Based on extensive laboratory testing and on-site experimental campaigns, the solution uses carbon dioxide instead of mineral acid for pH adjustment and integrates self-developed hydraulic ceramic plunger pumps, filter presses, CO-carbonation reactors, online water-quality monitors, and PLC intelligent control units. Its process includes solid-liquid separation, CO carbonation neutralization, sedimentation, and reclaimed-water recycling. The system holds invention patents, utility-model patents, and software copyrights. It has obtained "First Set of Equipment" certification from Zhejiang provincial authority and completed official new-product appraisal, with core technologies ranked at an advanced domestic-industry level. Commercial-scale projects have also been commissioned in different regions, supporting wastewater recycling and zero-liquid-discharge at concrete batching plants.

According to the test results, raw wastewater pH normally ranges from 12.6 to 12.8, with high levels of undissolved solids and dissolved alkalis that exceed typical acceptance thresholds for concrete-mixing water. Reusing untreated high-alkaline wastewater may create several challenges: 1. Alkali-aggregate reaction risk. Laboratory data shows that SiO dissolution from aggregate rises sharply when solution pH exceeds 12.5. Alkali-silica reactions inside concrete can cause volumetric expansion and cracking, affecting long-term durability. 2. Concrete strength development. Under high-alkaline conditions, cement hydration may produce specific C-S-H phases that boost early-age strength while hindering later-stage ion diffusion and hydration, resulting in insufficient long-term strength gain. 3. Admixture compatibility. High alkalinity can disturb the performance of polycarboxylate-based superplasticizers, lowering concrete flowability, shortening setting times, and accelerating slump loss during pumping operations. 4. Suspended solids. Excessive suspended solids can increase the water demand of fresh concrete, adsorb chemical admixtures, and further affect workability. Traditional treatment routes also have limitations. Simple sedimentation followed by discharge may pollute local water bodies, while mineral-acid neutralization requires handling corrosive chemicals and produces salt-loaded effluent. These conditions have created demand for wastewater-treatment technology that supports safer recycling at concrete batching plants. Sinou CO-Carbonation Wastewater Treatment System: Experimental Data Sinou conducted controlled experiments to evaluate the influence of feed-water pressure, flow rate, and CO supply pressure on neutralization performance. The basic reaction principle is: CO(g) + HO left and right HCO Carbonic acid dissociates and provides hydrogen ions to neutralize hydroxide alkalinity. Dissolved calcium and magnesium ions precipitate as calcium carbonate and magnesium carbonate solids. Under a feed-water flow of 25 m/h and a constant CO supply pressure of 0.05 MPa, increasing feed-water pressure from 0.05 MPa to 0.3 MPa reduced neutralization time per cubic meter of wastewater. Further pressure increases above 0.3 MPa showed marginal efficiency improvement. The reported optimum feed-water pressure was 0.3 MPa, balancing reaction performance and energy consumption. With feed-water pressure maintained at 0.3 MPa and CO pressure at 0.05 MPa, a processing flow rate of 30 m/h brought the cycle factor close to 1, representing optimum comprehensive system performance. Under fixed feed-water pressure of 0.3 MPa and a flow rate of 30 m/h, a CO supply pressure of 0.05 MPa delivered the minimum neutralization time per unit volume of wastewater. Under these operating conditions, the average CO utilization rate reached 80.26%. Treated effluent pH stabilized between 6.9 and 7.3, while dissolved solids, undissolved solids, and total alkalinity decreased significantly. The output water complied with JGJ63-2006 Concrete Mixing Water Standard and GB/T19923-2005 Reclaimed-Water for Industrial-Use Standards. Treated water can be reused for concrete batching, mixer-truck washing, and site-floor rinsing. Based on the test data, the CO reagent cost was approximately 2.0-2.7 CNY per m of wastewater, plus power-consumption cost of 0.25-0.35 CNY/m. The total operating cost shows clear economic advantages compared with purchasing fresh industrial water. Sinou CO-Carbonation Wastewater Treatment System: Process and Equipment Sinou Concrete Batching Plant Carbon Neutral Wastewater Treatment System is a CO-carbonation solution that neutralizes alkaline wastewater and supports reclaimed-water reuse at concrete batching plants. The full system includes a solid-liquid separation unit, CO reaction unit, sedimentation unit, and intelligent monitoring and control unit. Raw batching-plant wastewater first flows into a collection tank. Self-developed ZP-series hydraulic ceramic plunger pumps feed the wastewater into a filter press [ https://www.senyoubeton.com/sludge-dewatering-chamber-filter-press.html%20https://www.senyoubeton.com/concrete-batching-plant-sludge-chamber-filter-press.html ] for primary solid-liquid separation, where cement fines and suspended solids are retained as filter cakes. The filtrate then flows to a raw-water tank and is pressurized by ceramic plunger pumps before entering a two-stage spray-type carbonation reactor. Wastewater is atomized inside the reactor to increase gas-liquid contact area and react with vaporized CO. Neutralized water then flows into an inclined-plate sedimentation tank, where carbonate precipitates settle. The supernatant flows to a finished-water tank for recycling. Key equipment includes hydraulic ceramic plunger pumps designed for slurry media with fine solid particles. Their alumina-ceramic plungers provide wear resistance and corrosion resistance, supporting stable constant-pressure output for the carbonation reactor. The intelligent feed filter press removes suspended solids and helps reduce fouling risk inside downstream equipment. Separated filter cakes can be disposed of or reused externally. For automatic control, online pH transmitters and radar level sensors send real-time process signals to the PLC control system. The system interlocks CO solenoid valves and plunger-pump operation automatically. When pH rises above the threshold, the neutralization sequence starts; when pH reaches the target range, gas supply and feeding shut off accordingly. Mobile-phone APP remote monitoring supports unattended automatic operation and helps avoid human error caused by manual chemical dosing.

Sinou also formulated the in-house enterprise standard Q/ZSY 001-2020 and completed third-party laboratory testing, technical novelty search, and new-product appraisal. Commercial reference sites include Hubei Henggu Building Materials and Yuxi Shuidian Zhida Concrete. Site acceptance reports state that treated effluent pH stably maintained 6.5-6.8, while equipment modules including plunger pumps, reactors, and CO storage units operated reliably. For end users, the system supports closed-loop wastewater management without applying corrosive mineral acid or introducing additional sulfate and chloride salts. Reclaimed water meets concrete-mixing-water specifications, reduces alkali-aggregate-reaction risk, and supports stable concrete quality. It can also reduce the purchasing volume of fresh water and hazardous neutralization chemicals, while automated operation lowers manual workload for plant personnel.
