Wastewater Treatment System Maintenance - Cleaning Sprinkler Heads
**
I AM NOT A PLUMBER **
Our CajunAire Aerobic
Wastewater Treatment System had a reduced water flow out of the sprinkler heads so I had to perform a little minor maintenance on them. I am using the
Rain Bird Maxi Paw 2045A
Rotor (Sprinkler
Head). If you have a small screw driver and a Maxi Paw wrench, the maintenance is simple. I'd recommend that this be a part of the routine periodic maintenance on your aerobic sewage treatment system along with fire ant control around the aerator and periodic tank cleaning.
Here is an overview of how the aerobic treatment unit,
ATU, works. The manual states that no maintenance is required but that is not always the case!
The CajunAire Advanced Wastewater Treatment System is a
Class
I, mechanical, aerobic, wastewater treatment plant that will process your household sewage into a clear odorless liquid within 24 hours.
The process the CajunAire Advanced uses to treat common household wastewater is an extended-aeration
activated-sludge process. In your aerobic aeration system, air is introduced into the sewage through diffusion. When this air is diffused into the untreated wastewater, it promotes the growth of aerobic bacteria and other microorganisms that break down the organic material found in regular household sewage.
Sewage is first initiated into the system through the pretreatment chamber after which it flows into the aeration chamber. The liquid inside of the aeration chamber should be a light brown color. This color is caused by the return of activated sludge from the clarifier.
As the wastewater leaves the aeration chamber, it enters this clarifier which is also known as the “quiet zone”. No mixing occurs inside the quiet zone
. In the clarifier, the solids separate from the liquid and settle to the sloped-bottom of the clarifier; this quasi-solid and settling material is called activated sludge.
Activated sludge contains dissolved oxygen and bacteria that are supported by oxygen. The activated sludge is returned to the aeration chamber through a gap in the base of the clarifier wall. In the aeration chamber, the aeration chamber’s bubbling, rolling action feeds this activated sludge into the aeration process once again until the solids are adequately removed creating a
solid-free stream.
The solid-free stream that flows into the clarifier exits the system as a high quality, treated stream that is ready to be re-introduced into the environment.
You are not required to perform maintenance to the unit at any time.
The System utilizes living organisms that require certain conditions to work and perform properly. Your new unit can treat most any type of household wastewater you put into it
including showers and baths, clothes and dishes, and toilet water.
However, there are also some things that you should try to keep from going down the drain. These items include but not limited to grease in any amount, hair in large amounts, and the use of garbage disposal in heavy volumes.
The following is a list of products and items that should never be allowed to flow into the Wastewater Treatment System:
1.
Large amounts of bleach or any other chemical that can kill bacteria
2. Large amounts of disinfectants
3.
Chemicals that have high volumes of bacteria killing agents
4.
Cigarette filters, condoms, feminine products, large paper products, or any rubber or plastic products
5.
Shrimp shells, coffee grounds, or any amount of cooking grease and oils
6. Chemicals that are designed to clean out drains or correct “septic tank” problems
You you may need to have a competent septic tank cleaning service clean your unit every 3 to
7 years depending on your daily loading. You should expect to obtain one inch of sludge at the bottom of your unit every year.
