Small Community System

SCS Wastewater treatment systems provide high performance effluent treatment. A regime of yearly inspection and maintenance is essential to ensure that your system continues to perform to the same high standards throughout its lifetime. Anua Environmental South offer a range of Service Agreement options. Choose one to suit your needs and get the best from your system.

This SCS- Wastewater treatment system Inspection Agreement includes the following:

  • Inspection visit agreed arrangement with the customer
  • Detailed report provided to customer indicating status of the mechanical and electrical
  • components for each of the following tanks/sections , where applicable
  • Inlet Pump Station (where applicable)
  • Primary Settlement section
  • Storage Section (where applicable)
  • Anoxic Section (where applicable)
  • Aeration Section (where Applicable)
  • Preduction Equipment (where applicable)

 

Single House Systems

Sewage Treatment Systems provide high performance effluent treatment with low running costs. A regime of yearly inspection and maintenance is advised to ensure that your system continues to perform to the same high standards throughout its lifetime. Anua Environmental South offer a range of Service Agreement options. Choose one to suit your needs and get the best from your system

Free Sludge Level Assessment and Desludging Recommendation:

Anua Environmental South will assess the sludge level in your sewage treatment system free of charge when they carry out the system inspection. Based on this assessment we will then advise when you should have your sewage treatment system desludged. The EPA guidelines on Treatment systems for single houses recommend that you should desludge your septic tank once per year or when scum is noticeable in the second chamber of the tank and/or the depth of sludge in the second compartment is greater than 400mm.

The peat filter can in some ways be considered to be a fixed film filtration system much like other sewage treatment filters composed of sand or artificial media. Peat, however, has unique chemical, physical and biological properties, all of which contribute to the sewage treatment process. Sewage treatment within the peat filter is accomplished by a combination of physical filtration, chemical adsorption, and biological treatment by microorganisms. Peat fibers are polar, have a high surface area, and a highly porous structure (90-95% porosity).

These properties enable the peat bed to hold a large amount of water, much like a sponge. As a result, effluent has a long residence time in the peat. As the wastewater is wicked through the peat it flows in a thin film over the surfaces of the peat fibers. This allows the effluent to become aerated, become exposed to the acidic chemical environment of the peat, and come in close contact with the microbiological community inhabiting the peat. The relatively constant moisture content of the peat filter also enables the survival of the natural microbial population in the peat even when the system is not being actively used. Moisture in the peat also helps keep the temperature of the peat bed relatively constant even when outside air temperatures change. This likely accounts for peat’s ability to perform well even in very cold conditions. Solids that are larger than the interstitial channels in the peat are trapped on the peat fibers as the effluent trickles through the peat. This accounts for the very low total suspended solids seen in finished effluent and may account for some removal of BOD as organic particles are trapped for later digestion. The highly polar nature of the peat fibers creates an environment with a high cation exchange capacity.

Many wastewater components become chemically adsorbed to the peat fiber surface causing them to be trapped in the peat. Peat’s highly porous structure and very high surface area make the peat bed an ideal environment for supporting an aerobic microbiological community that performs biological treatment of the sewage. Within several weeks of use the peat filter is colonised by a range of microorganisms and invertebrates from the septic tank effluent and the surrounding soil. These include bacteria, fungi, protozoa, nematodes, earthworms, rotifers and others. Treatment of the septic tank effluent is performed mainly by acid-tolerant bacteria and fungi living in the peat media. Pathogenic bacteria in the wastewater undergo significant die-off in the peat due to the acidic conditions and predation and competition from the natural microbiological community in the peat. It is also possible that the fungi in the peat produce antibiotics and that the peat itself releases antibiotic and phenolic substances that further act to reduce bacterial numbers.

Influent and Effluent sampling

The primary use of an effluent sampling is to evaluate treatment system performance in order to verify compliance with specific discharge limits, or to compare the performance of individual systems. Large municipal treatment plants sample directly from an effluent channel which will give an indication. Anua Environmental will determine if an influent sample is required for the treatment plant. Samples will be sent to the laboratory and will be tested. A sample result with data will be presented to the client. Anua Environmental will advise client if results are within specified parameters.

Controlling phosphorous discharged from municipal and industrial wastewater treatment plants is a key factor in preventing eutrophication of surface waters. Phosphorous is one of the major nutrients contributing in the increased eutrophication of lakes and natural waters. Its presence causes many water quality problems including increased purification costs, decreased recreational and conservation value of an impoundments, loss of livestock and the possible lethal effect of algal toxins on drinking water.
