Septicity in pumping mains
Hi Nilam. If you have water treatment works using iron based coagulants then these can be used to help overcome septicity. Typically the coagulants will be taken from DAF plants and considered a waste sludge to be disposed of. They still have good sequestering potential and can help keep H2S problems down. In fact there are probably many situations where WTW discharge to sewer and companies are unaware of this beneficial effect. You could take the ferric coagulant and discharge it to the network at suitable positions. Worth a try and although it might not eliminate the problem it might help and also find a sustainable beneficial use for the coagulant.

As per response to John Cook,
Alternative additive chemicals could offer a benefit, but we are ideally looking for an alternative to chemical use.
Thanks for your comments.
