Treatment of  Sewerage Treatment Plant (STP) Waste Water

Treatment of waste water discharge into high grade quality water will enable a facility to recycle water for use in a wide range of applications within the facility. Every litre of water that is recycled represents one less litre that must be purchased, a positive step forward to enhancing the environmental credentials of your facility whilst saving money.



Recently we have engaged Udayana University to undertake chemical analysis on our Starfish Purification Technology. They have done this by analyzing water samples before and after “Starfish Water Purification” treatment of these samples.

Below is an example of a STP (Sewerage Treatment Plant) water sample, key results are outlined below. In summary we have converted a STP water sample to high grade drinking quality water which exceeds WHO (World Health Organisation) standards. We have also achieved high grade drinking water from PDAM (town water) and Deep Well water supplies.

How It Work

Starfish water purification units are constructed in a modular manner with a number of reactor chambers which utilize an alternating combination of Ozonation, UV sanitation and Advanced Oxidation ratios to clean, sanitize and purify water. Starfish technology can be utilized across all size requirements from small water users to large municipal applications.The system in not pressurized and can operate under gravity flows if required. The system uniquely produces it own ozone with the capability to produce 80-120 grams of ozone per litre of water depending on the quality of the source water.

The un-depleted ozone is reverted back to oxygen automatically within the system.The UV produced within the system utilizes a specific wavelength of UV light which maximizes the sanitation and disinfection rates. This unique combination of ozone and UV light kills bacteria and pathogens, clarifies and oxygenates the water and removes odour. The process of fractionation floats off all foreign particles to the waste line. The advantage of this process is firstly that the waste is germ free and secondly that the waste is minimal (approx 5%).


What is Ozone ?

Ozone (O3) is a component of fresh air that occurs naturally, as a result of reaction between the ultraviolet rays of the sun with the top layer of the earth’s atmosphere. Ozone is a gas product with the chemical formula O3, Ozone itself is a type of gas that is highly reactive and unstable, with a very short life span (20-30 minutes) before returning it into oxygen.

Ozone in Water Purification Applications 

 Ozone is a very strong disinfectant and oxidizer. Any pathogen or contaminant that can be disinfected, altered or removed via an oxidation process will be affected by ozone. It is the strongest of all molecules available for disinfection in water treatment and is second only to elemental fluorine in oxidizing power. Compared to chlorine, the most common water disinfection chemical, ozone is a more than 50% stronger oxidizer and acts over 3,000 times faster. 

Over the years, ozone treatment systems have been used for purifying drinking water in various parts of the world. In addition, ozone finds a wide application in commercial and industrial works like decontaminating cooling towers etc. Ozone is also used in processing foodstuffs like meat, poultry, and seafood.  Ozone has full FDA (Food & Drug Administration, USA) and similar authorities around the world approval for direct food contact applications.

Ozone easily kills:  

  • Bacteria
  • Yeast
  • Cysts
  • Virus
  • Fungus Spores
  • Protozoa
  • Mold Spores, Fungal Pathogens and Algae

Starfish Ozonation Chamber

Starfish technology is a technological breakthrough method of Ozonation. The ozone-enriched water flows into a chamber to allow for sufficient contact time. During this contact time, ozone molecules decay to form oxygen molecules and free hydroxyl radicals. It is both the ozone and the highly reactive free radicals which oxidize organic molecules. Through this oxidation, toxic herbicides and pesticides are reduced to more environmentally friendly components.

Ozonation destroys Cryptosporidium, Legionella and other naturally-occurring organisms. It also can reduce the formation of trihalomethanes (THMs), which result from the interaction of chlorine and naturally-occurring organic material in the source water.

What is Ultraviolet Light ?

Ultraviolet disinfection is a means of killing harmless micro organisms in a dedicated environment. These micro organisms can range from bacteria and viruses to algae and protozoa.

UV disinfection is used in water purification, sewage treatment, protection of food and beverages and many other disinfection and sterilization applications. A major advantage of UV treatment is that it is capable of disinfecting water faster than chlorine without cumbersome retention tanks and harmful chemicals. UV treatment systems are also extremely cost efficient.

What is photoelectric chamber ?

The photoelectric chamber utilizes Ultraviolet disinfection which consists chemical-free process. UV attacks the vital DNA of the bacteria directly. The radiation initiates a photochemical reaction that destroys the genetic information contained in the DNA. The bacteria lose their reproductive capability and are destroyed. Even parasites such as Cryptosporidium or Giardia, which are extremely resistant to chemical disinfectants, are efficiently reduced. The microorganisms are eliminated from the water. The photoelectric chamber is also used to remove chlorine and chloramines in a process called Photolysis.

What is advanced oxidation

Advanced oxidation is a step in the advanced water treatment process that uses powerful oxidants and ultraviolet light to destroy trace levels of organic or micro biological organisms. Advanced Oxidation Processes (abbreviation: AOPs), refers to a set of  treatment procedures designed to remove organic and inorganic materials in waste water by oxidation.  The contaminant materials are converted to a large extent into stable inorganic compounds such as water, carbon dioxide and salts, i.e. they undergo mineralization.  The AOP procedure is particularly useful for cleaning biologically toxic or non-degradable materials such as aromatics, pesticides, petroleum constituents and volatile organic compounds in waste water.

Starfish Advanced Oxidation

 The Advanced Oxidation chamber makes use of oxidants to reduce COD/BOD levels, and to remove both organic and oxidisable inorganic components. The process can completely oxidize organic materials to carbon dioxide and water. Oxidation of target contaminants are caused by direct reaction with the oxidizers, UV photolysis, and through the synergistic action of UV light, in combination with ozone (O3). UV-oxidation processes can be used to simultaneously destroy trace chemical contaminants and provide high-level disinfection. The combination of Ozone and UV in the single chamber provides the system with extended microbiological kill power and harmful chemical removal capability.

Starfish Optimized Fractionation

Fractionation is an efficient, cost-effective way to remove small particles and dissolved organic wastes from water while at the same time increasing dissolved oxygen levels.  Fractionation is mixing ozone, air and water together through the Starfish Optimized Fractionation process. As the bubbles travel through the chamber, they collect dissolved and small organic waste particles, on their bubble walls. These particles are then expelled from the system through the fractionation discharge as waste. The combined advanced processes within the Starfish system ensure that even the waste is pathogen free.
