Chemical Dosing Tips for Sewer Treatment Plants

If you run a sewer treatment plant or any other type of sewer treatment facility, you need the right chemical dosing solutions to help purify your water. The exact solutions you need vary based on the size of your facility, but in general, you should keep the following tips and ideas in mind.

Make Sure You Have a Back Up

Even with a small sewer treatment plant, you have to keep constantly cleaning the water. In most cases, you cannot afford much downtime. So you don't have to worry about that, you should consider investing in a chemical dosing skid.

Generally, this setup contains two or more chemical dosing pumps. These pumps release a predetermined amount of various chemicals into the system, and they save you time and money because you don't have to measure and put in the chemicals yourself or pay a staff member to do that for you.

Additionally, the extra pumps act as a backup, and if the main pump stops working, the extra pump gets into action. This helps to ensure that your sewer treatment plant never has to shut down.

Consider pH Buffering

In most cases, you can't just release the same amount of chemicals into your system all the time. The need changes as the composition of the waste water coming into your facility changes. In particular, during times when there is a lot of sewer usage in your area, you need more chemicals.

Generally, during these times, the pH levels in your facility tend to be higher. To deal with that, you need a chemical dosing system that includes pH buffering. Basically, this part of your system measures the pH balance in your water. Then, it transmits that information to your dosing pumps so they can release chemicals accordingly.

Remember to Address Phosphates

One area you always need to address with any type of sewage treatment is phosphates. You need to remove the phosphates before releasing the water from your treatment area into the rest of the freshwater cycle.

There are a few options to deal with phosphates, but typically, you need to add an iron-based chemical such as chloride or ferric sulphate. To ensure you release the right amounts, you also need chemical dosing pumps that measure and release these elements.
