There are several aspects of industrial wastewater treatment Sydney that common people like us could not understand
because of the technicality involved in them. One such aspect is iron based
coagulants that help materials in getting destabilised and come together to
form clumps. The best part of these coagulants is that they are totally soluble
in water and thus, can be used in different kinds of wastewater treatment Sydney application. There are several of them and each
has its own pros and cons and some of them are discussed in this post.
Ferric Chloride (FeCl3)
Pros:
- According to the experts dealing with hazardous substances Sydney, it can react with phosphates and/or alkalinity to form insoluble iron salts.
- This coagulant is ideal for removing metals such as Cu, Ni, and Zn, solids, and phosphorous.
- Moreover, it can also be combined with hydrogen peroxide to form Fenton's Reagent.
- It is worth noting here that Fenton’s Reagent is used to oxidize organic contaminants in water.
- It is a highly corrosive compound.
- It does stain on contact, so the water treatment equipment may take on a brownish color.
- Moreover, it generates a large amount of sludge during chemical precipitation.
Ferrous Chloride (FeCl2)
Pros:
- According to experts of liquid waste removal, it is less corrosive than ferric chloride.
- It can be used for a hexavalent chrome reduction, phosphorous removal and metals removal.
- The first con is that it leaves stains on contact.
- It could also generate a large amount of sludge during chemical precipitation.
Ferric Sulphate (Fe2(SO4)3)
Pros:
- Those engaged in wastewater treatment Sydney say that this coagulant is very effective in treating oily water, removing turbidity and phosphorus, and removing metals.
- It can be very effective in terms of sludge dewatering.
- Just like those discussed above, this version too leaves stain on contact.
