Dioxygen Difluoride

Dioxygen Difluoride is a aggressive fluorinating compound of fluorine and oxygen with the molecular formula O2F2. It exists as an orange solid that melts into a red liquid at -163 °C. It is an extremely strong oxidant and decomposes into oxygen and fluorine. Dioxygen Difluoride's major uses are to bleach pulp and paper and disinfect sewage and drinking water.

Ltd is a Major manufacturer and Supplier of ferrous sulfate and Rech is certifacated by ISO 9001:2008 and FAMI-QS and finished European REACH Preregistration. Application Ferrous sulphate monohydrate is a mineral additive in animal feel. As a blood tonic substance to livestock, it can stimulate the growth of animal's body. It can also be used to make pigment such as red ferric oxide etc. Granule material is good fertilizer, which can effectively improve soil , move moss and lichen. It also is used as pesticide for prevention of pathological changes of wheat and fruit tree. Meantime, it is the catalyst making plant green and important for plant absorption In industry field, ferrous sulfate heptahydrate can be used as a substitute for aluminum sulfate in the water treatment. It causes impurities to clump together in masses, called flocculation, or used to remove phosphates in sewage treatment. Packing Net weight 25kgs, 50kgs per each plastic woven bag, or 1000kgs to 1350kgs per each package?or according to client request. Delivery We will arrange shipment from Huangpu and Changsha Port within 15 days after receiving your order.

GREASEGUARD LS-10 is a fat, oil and grease eliminator used in waste water treatment. It is a controlled release block containing a synergistic blend of microbes capable of degrading fats, oils, grease and other organic waste. It can be used to control deposits by placing in grease traps, sewage ejector systems, septic systems and municipal lift stations. Continuous use of GREASEGUARD LS-10 will reduce the buildup or fats, oils and grease on system surfaces. This reduces or eliminates the need for manual physical cleaning and reduces overall maintenance requirements.

Halotolerant bacteria

[Product traits] Powder

[Main ingredients] Bacillus & coccus which can grow spore(endospore)

[Content of viable bacteria] ≥20 billion/gram 

[Applicable field] Municipal sewage, chemical sewage, printing & dyeing  sewage, landfill leachats, foodstuff sewage and other anaerobic system for industry wastewater.


[Main Functions]

If the salt content in sewage reaches 10%(100000mg/l),the bacteria will take acclimatiion and biofilm formation on biochemical system quickly.

Improve the efficiency of organic pollutant removal,to make sure the BOD?COD&TSS content is OK for brine sewage.

If the electric charge of sewage has large fluctuation,bacteria will strengthen the settleability of sludge to improve the effluent quality.


[Application method]

(calculated by biochemical pond),for industrial sewage,first dosage should be 100-200 gram/m3;for high biochemical system,dosage should be 30-50 gram/m3;for municipal sewage,dosage should be 50-80 gram/m3.



The tests show that the following physical and chemical parameters on bacterial growth is the most effective:

PH: average range between 5.5 to 9.5, it will grow most rapidly between 6.6 -7.8 , and best ph value is 7.5.

Temperature:  take effect between 8 ? - 60 ?.Bacteria will die if the temperature is higher than 60 ?. If it is lower than 8 ? , bacteria will not die, but the growth of bacteria cell will berestricted a lot. The most suitable temperature is between 26-32 ?.

Dissolved oxygen : aeration tank in sewage treament,dissolved oxygen content is at least 2 mg/liter.The metabolic and regrade rate of bacteria could speed up by 5-7times with fully oxygen.

Micro-elements: proprietary bacteria group will need a lot of elements in its growth, such as potassium, iron, calcium, sulfur, magnesium, etc., normally it contains enough mentioned elements in soil and water.

Salinity: it is applicable in high salty water,the maximum tolerance of salinity is 10%.

Poison resistance: can more effectively resist chemical toxic substances,including chloride,cyanide and heavy metals,etc.

*When the contaminated area contains biocide,need to test the effect to bacteria.
