Common Problems with Biological Wastewater Treatment
Most problems with biological wastewater treatment systems occur at the engineering and design stages. When studies aren’t completed for long enough periods of time over vast-enough amounts of data, it’s common for a system to fall short in some way. Here are some of the engineering and design stage issues we see the most.

- What is sodium dichloroisocyanurate?
- ?
- ) Sodium dichloroisocyanurate (INN: sodium troclosene, troclosenum natricum or NaDCC or SDIC) is a chemical compound widely used as a cleansing agent and disinfectant. It is a colorless, water-soluble solid, produced as a result of reaction of cyanuric acid with chlorine.
- Is sodium dichloroisocyanurate safe?
- Studies of the toxicity of sodium cyanurate are appropriate for assessing the safety of sodium dichloroisocyanurate, because any residues of intact sodium dichloroisocya-nurate in drinking-water would be rapidly converted to cyanuric acid on contact with saliva. Both sodium dichloroisocyanurate and sodium cyanurate have low acute oral toxicity.
- Can Sodium dichloroisocyanurate be used to disinfect drinkingwater?
- Where sodium dichloroisocyanurate is used for the disinfection of drinking‐water, exposure will be to both the chlorinated species and residual cyanuric acid. The concentrations will relate directly to the quantities added to achieve adequate disinfection.
- Can Sodium dichloroisocyanurate dihydrate be used as a chlorine source?
- Sodium dichloroisocyanurate dihydrate can be used as a chlorine source to convert alkoxyl- s -triazines into N -chlorinated alkoxy- s -triazines.
