Water Treatment Chemicals
★Due to different conditions of industrial wastewater, depend on the test results from lab testing and pilot
plantcombined utilization of two or even three of our series may perform the best, especially in the case that pigmentum cannot coagulate and needs pre-treatment with flocculants.
Generally wastewater after biological treatment would be dealed with single one cationic coagulant for expected effect. Relevant pre-treatmentis necessary in case that high BOD, COD, oil and pigmentum are found in the wastewater,Sludge needs further dehydration which can be done
with one single polymer after final concentration and cationic coagulants could be perfection.
★ all solid-liquid separation processes in municipal (or sewage) wastewater treatment. Examples as follows:
●Primary sewage treatment.
Often the use of an anionic polymer in combination with an inorganic/organic coagulant can reduce the bio logical loading on the secondary treatment. Additionally by accelerating settlement rates in the primary clarifies the size of the clarifier can be reduced, resulting in a significant capital saving.
●Activated sludge treatment.
Product choice is entirely depended on the application although typically a medium to high charge cationic polymers is required.
●Digested Sludge Treatment.
Usually cationic polymer with high electric quantity performs better while the choice of molecular weight depends on solid-liquid separation method. We may assist our customer to choose appropriate products regarding performance of dehydrator.
Mineral Dressing Chemicals
The flocculant for mineral processing is an important drug additive in the solid-liquid separation process of mineral processing. It is mainly used in the concentration of fine & tailings, the purification treatment of mineral processing wastewater and tailings filling, etc.
The special flocculant for mineral processing produced by our company (polyacrylamide) can be produced according to different needs. They have good stability, strong adsorption and bridging ability,good flocculation effect,fast settle speed,and good resistance against high temperature, salinity, acid, alkali and other characteristics.
Application:ferrous metals, non-ferrous metals, precious metals,non-metallic minerals and energy minerals
Specialty Chemicals in the Oil Field
Enhanced Oil Recovery(EOR)
This process has been used for several years in assisting the operator to increase the efficiency of oil recovery of tertiary floods. Intertiary oil recovery technologies, polymer flooding is a very important tertiary oil recovery technology.
Polymer flooding
●Control the mobility ratio of the water injection and the general mobility ratio of high water containing stratums.
●Adjust the water absorption of high and low water containing stratums.
●Increase the water content of low penetrating oil stratum
●Expand the swept volume of water injection
●Decrease the water content in the oilfield
●Enhance the oil recovery rate of the oilfield.
Water shutoff profile control
After many years of injection, especially to the super high permeabiliby formation, water injection layer always has high erpermeability zone in some areas. The oil displacement agent will directly flow into the high permeability zone, which will decrease the effect of chemical flooding. So it needs to close off the high permeability zone with lower oil saturation. By applying Water Profile Control technology and products , the desired change in the profile can be achieved thereby controlling the water content and improving the oil recovery rate.
Drilling Mud Additives
products has been used successfully for many years as drilling mud additives for viscosity modification. A comprehensive range is available so that optimum performancecan be achieved to suit the particular type of water based drilling mud systemused by the operator.
Viscosity Modification
Typically polymers or PHPA's are used on their own or inconjunction with bentonite,a s extenders, increasing the drilling mud viscosity thereby resulting in improvements in the removal of cuttings, better control of mud densities and lubrication of the drill bit. Additionally, during downtime, due to the thixotropic nature of the drilling mud system the cuttings will be held in suspension thereby not causing any major problems with solids settlement.
Fracturing fluid/Acid thickener
Fracture and Acid is suitable for medium/low permeability, and fissure reservoir conditions, and it is a critical measure forincreasing well injection.Fracture and Acid means to take the use of acid toincrease flow conductivity of limestone, and it takes use of thickened acid toincrease the viscosity of the acid and decrease the filtration loss during theacid and fraction execution. Upon the increase of injection pressure, it will easily reach to the pressure of the stratum fraction.The purpose of enlarging the length of the fissure is to optimize the effect of the acid. During this process,many chemicals will be used.
