This is a brief overview of an independent study carried out in Suva, Fiji. If you would like to request a full copy please get in contact. Background Suva is the largest city in Oceania with one fifth of the Fijian population, approximately 180,000 in 2005, living in this urban center. The Samabula Sewage System … Read more →

Algae Degrading Seed can be used to maintain a balanced ecosystem in outdoor wastewater treatment systems, natural lagoons and ponds. The organic wastes of pond life forms allow for the production of soluble phosphorus and nitrogen, excess of these compounds may stimulate the overgrowth of algae. Algae Degrading Seed uses natural bacterial ability to utilise … Read more →

Background Frequently in New Zealand and other places in the world, dairy farm animal waste is discharge from milking sheds into on site wastewater oxidation ponds for treatment. Oxidation pond wastewater *without* Biems may be high in H2S, BOD and ammonium plus other unwonted trace elements. We know from expertise that by spraying the surface … Read more →

Biems was presented with the problem of an old landfill that had excavated for infrastructure works.  The issue created was that Hydrogen Sulphides and other gases were leaching from the ground.  The traditional solution is to use Air Scrubbing which captures the gases from the works site and then is processed through mechanical & carbon … Read more →

Prior to using BIEMS in the wastewater filtration system the intensity of odour and the concerns of the public were such that the media had targeted this property as an environmental hazard. The plant on Waiheke Island in the Auckland Harbour is a relatively small plant handling approximately 22 –23 cu metres per day of … Read more →

This page highlights the small doses of BIEMS required to achieve favourable outcomes. “The input of sewage from the city area is average of 100 litres per second during dry weather conditions, sewage from other areas constitute another 100 litres per second, the total volume of BIEMS was calculated at approximately 4.5 litres per day … Read more →

The following are extracts from a memorandum dated 1st July 1997 from the Acting Senior Scientific Officer, National Water Quality Laboratory, Fiji. “The sample of BIEMS which you sent recently for analysis has been tested with the raw sewage at Suva Regional Wastewater Treatment Plant, it is a fairly large plant servicing the area around … Read more →

In this scenario Oxygen was injected into the Raw Sewage with the aim to increase the microbiological activity.  However it was found that it depleted very rapidly within four hours and actually decreased the level of microbiological activity. BIEMS was dosed to the same system to increase the microbiological activity.  As you can see below … Read more →

A use case of BIEMS Bioremediation returning an Oxidation Pond in New Zealand back to an aerobic state. Background The pond was fed with Animal Waste Discharge, had become anaerobic and was giving off obnoxious odours as far as 5km away.  They were faced with local government penalties and a strict timeframe to address the … Read more →
