M<sup>+</sup> FLO-LDHmagnetic flocculation + chemical desalt and hard water purification system

M⁺ FLO-LDHmagnetic flocculation + chemical desalt and hard water purification system

M⁺FLO-LDH desalting mechanism: The mechanism of salt removal is based on the characteristics of interlayer anion exchange of LDHs/ layered compound metal hydroxide. In order to remove certain anion A^n-, the corresponding compound metal LDH-A^n- is added, and the reaction occurs under certain conditions such as temperature and PH. Anion in water A^n- (CO₃^2-, SO₄^2-, NO₃^-, PO₄^3-, F^-, Cl^-...

Magnetic mixing/flocculation magnetic separation deep purification treatment of black and odorous water body typical application cases

Nanjing Xuanwu Hunanzha Water Purification Station is used for the purification of polluted water bodies intercepted by river channels to ensure that the water bodies discharged into Xuanwu Lake meet the government's limits. The water purification station is designed to handle 10,000 tons/day, and the influent water quality is NH3-N≤20mg/L; TP≤2mg/L; CODcr≤100mg/L; SS≤50mg/L; PH=6-9, the treated effluent must meet the following water quality indicators:

River water magnetic flocculation purification treatment for industrial water

The Yellow River water conductivity of 900-1110µs/cm (twice that of groundwater), salt content of 700mg/L (twice that of groundwater), organic content of 3-5mg/L (1mg/L of groundwater), turbidity, etc. (especially SO42-, Cl-, Na+, etc.) are much higher than that of groundwater. The water quality data collected are as follows:

Circulating cooling water discharge water magnetic flocculation/coagulation deep purification treatment and reuse system

In the open circulating cooling water system, the concentrations of Ca²⁺, HCO^3-, SO₄^2-, Mg²⁺, SiO₃^2- ions and harmful substances such as suspended matter, biological colloid, organic matter and oil will continue to rise with the evaporation of circulating water and cause problems such as ① scaling and deposition ② corrosion ③ microbial (bacteria, fungi and algae) breeding and reproduction. The solution is to reduce the hardness/reduce the concentration of corrosive ions (such as Cl-)/reduce the organic and microbial content. The concentration is usually reduced by blowdown/simultaneous water refill and the harmful substances are controlled within the specified allowable limits, see the annex "Industrial circulating cooling Water treatment design Code" GB/T50050-2007.

Biological filter backwashing wastewater purification treatment

The original design of the DN/CN backwashing wastewater purification treatment is Veolia MUTIFLO high efficiency sedimentation tank (1212m), but the operation effect is not good. There are more floating substances on the surface of the sedimentation tank and more flocculent substances in the effluent, which not only increases the agent consumption of MUTIFLO sedimentation tank, but also seriously exceeds the limit value of suspended substances in the effluent. As a result, frequent backwashing of biological aerated filter has seriously affected the treatment capacity and effect. The solution of MUTIFLO sedimentation tank for original backwashing wastewater by magnetic flocculation sedimentation process is selected, and a magnetic sludge separation and magnetic powder recovery recycling system can be installed in the sludge discharge pipeline of the backflow sludge pump at the bottom of the original sedimentation tank. The treatment capacity of the reconstructed magnetic flocculation sedimentation tank is 2000m3/h. The processing performance and system operation consumption indicators are as follows:

Flocculation/coagulation treatment of effluent tail water is used for industrial circulating water

The tail water of the sewage plant will still contain high salt, hardness, alkalinity, phosphate, suspended matter, organic matter, bacteria and heavy metals and other harmful substances, which will be used in industry such as circulating water and need to be further treated to further remove ① hardness, alkalinity, phosphate, suspended matter colloid ② dissolved organic matter ③ inorganic salt ④ bacteria and algae. The most commonly used process is lime/soda ash coagulation precipitation purification treatment, which can effectively reduce hardness, alkalinity, phosphate, suspended matter, heavy metals, etc. (and can kill bacteria), and also has a certain removal capacity for total organic matter and silicon, fluorine, free chlorine, etc. The treated water can be used as industrial circulating water replenishment or continued reverse osmosis RO/DTRO desalting treatment to produce desalted water (high concentration rate circulating water replenishment). Attached is "Industrial circulating cooling water treatment design Code" GB/T50050-2007.

Organophosphorus and hypophosphorus were removed by M<sup>+</sup>C catalytic oxidation and M<sup>+</sup>FLO magnetic flocculation

Organophosphorus and hypophosphorus were removed by M⁺C catalytic oxidation and M⁺FLO magnetic flocculation

The phosphorus content of wastewater produced by pharmaceutical, starch processing, wine industry, slaughtering and other industries is often much higher than that of most industrial wastewater, and the composition is complex, including phosphorus, hypophosphorous, phosphorus and organophosphorus. Usually, the main process of the treatment of such wastewater is: AAO biological nitrogen and phosphorus removal → chemical phosphorus removal/high-density sedimentation tank + filter, phosphorus containing wastewater after biochemical treatment, most of the organophosphorus, metaphosphorus, polyphosphorus, etc. can be absorbed by microorganisms and discharged with microbial sludge, but often there will be some residual, and some are decomposed into small phosphorus molecules. Chemical phosphorus removal agents such as aluminum or iron salt are added to the effluent after biochemical treatment. Aluminum AI3+ ion or iron ion Fe3+ combine with phosphoric acid to convert dissolved phosphorus into particulate phosphorus precipitation. Phosphorus removal by metal salt follows the following three steps:

Magnetic flocculation/coagulation precipitation purification and treatment system for coal chemical gasification washing wastewater

The main pollutants are suspended SS, cyanide, sulfide, ammonia nitrogen, COD, coal tar, volatile phenol, etc. The waste water can be recycled after purification and cooling treatment (when the dissolved pollutants reach a certain limit value, it needs to be discharged and new water is added at the same time), or it can be pre-purified and combined with other process wastewater into the regulation tank of the sewage treatment plant.
