A Natural Bio-Organic Wastewater Treatment for Sewage - A new andtrending concept

In a recent article, "Natural Bio-Organic treatment for wastewater - an environmental and financial imperative", we discussed the merits of Natural Bio-Organic practices generally in water treatment. In this article we will look specifically at the sewage wastewater treatment process and review a particular application of a Natural Bio-Organic solution.

A general review of the many challenges facing sewerage plants includes:

Traditional solutions and their shortfalls

1. Chemicals



2. Filters



3. Bacteria



4. Enzymes



The Natural Bio-Organic Solution

The ideal solution is to treat the causes of STP problems and not just the symptoms, which is why we advocate the application of a Natural Bio-Organic Concentrate into selected parts of the wastewater treatment system.

Expected Results

Other Major Benefits

Sewerage Plant Infrastructure and Maintenance Cost Savings

Using a sewerage network and treatment plant in Australia as an example, we can underline the financial benefits of using a Natural Bio-Organic solution to the treatment of wastewater:

Natural Bio-Organic concentrate NOT used at the STP

When a Natural Bio-Organic concentrate IS used at the STP


Approximately $10 million spent on major refit every
15 years

Major refit pushed back to
25 years

Allowing for interest on the capital - annual savings approximately $290,000

Direct annual maintenance - $400,000

Direct annual maintenance - $250,000

Difference - $150,000

Annual maintenance - labour

Annual maintenance - labour

Difference - $125,000

Power cost

Power cost

Difference - $250,000

  1. An operating cost benefit of about $375,000 per year
  2. With a total capital and operating cost benefit of around $650,000 per year

Leave it to Nature

Perhaps, after all these years of under-achieving methods used in processing the waste created by life on earth, it is difficult to comprehend that such a natural and simple solution to an ever enlarging environmental dilemma - human waste treatment - is right here under our noses (excuse the pun)…….or maybe more succinctly, under our boats.

The fact is that almost 20 years ago an inventor in southern Australia found the answer to coping with the production of carbon-based human waste…..and it lies right here on earth just below the surface of the ocean! Since then the formula has been tried and tested in numerous wastewater environments with consistent success.

Sewage Network Case Study - Grease and Septicity.

Cairns Regional Council, Port Douglas Sewage Network.


Following 18 years of successful use of a Natural Bio-Organic Solution by Cairns Water, it decided to introduce it into a new and problematic sewage network. The Port Douglas (Douglas Shire): This had been amalgamated into Cairns Water and the maintenance and operation of the network and Sewage Treatment Plant had become their responsibility.

The restaurant precinct at Port Douglas was generating a vast amount of Oil and Grease. Due to an ineffective Trade Waste management system the pump wells were performing as communal grease traps. The accumulating organic load (Oil and Grease accumulating on the aqueous phase) led to septicity, odour and corrosion issues within these pump wells and the network in general.

The disproportional amount of well washing and education, along with sewage surges through blockages and network repairs/replacements, along with after-hour's operator call-outs, became an operational expenditure burden too great to ignore.


A Natural Bio-Organic Concentrate was introduced into 7 pump wells to reduce the accumulation of Oil and Grease in the restaurant precinct and in the pump wells that were subject to septicity due to extended retention times near the extremities of the network. Remarkable results were achieved in Phase 1 during 2010 and 2011; Phase 2 is currently under way.

Details and Outcomes


Total Network Flow Rate: 2,500,000 L/day

Dose Rate: 12 mg/L

Dosing Points No.: 7


Elimination of Septicity in Network.

Reduction of Dissolved Sulphides in Network.

Reduction in Odour in Network.

Reduction in Oil and Grease in Network.

Reduction in Ammonia in Network.
