Water sources throughout the world are rapidly becoming fouled and polluted by human activity. The scarce resource of clean water is becoming even more scarce. It is therefore important that where human activity is the cause of such pollution steps be taken to eliminate or minimise the resultant waste's impact on the environment. The Heal Group has developed a range of small to medium Treatment Systems that can treat this waste water at its source to help minimise the impact of such waste and to help keep the local environment in balance.
The Heal Group is proud to offer the following Waste Water Treatment services:
Package Sewage Treatment Plants
Mechanical Equipment Supplies
Tertiary Sewage Treatment Equipment
Solid Waste Management
Compost Treatment Systems
Effluent U.V. Systems
Separation Screens and Clarifiers
Zeoflocc Capacity Extension Systems
Package & Civil Pump Stations


Christmas Island Waste Water Treatment Plant

Christmas Island is a good example of raw sewage being released into the sea. It was thought that as Christmas Island is located in the middle of the Indian Ocean, this release would not effect the overall balance of the eco system. Though to a large extent this could be correct, the Australian Government felt that this could not continue. The Heal Group, in association with Entact Clough of the Clough Group, designed a 1.0 Ml/day Sewage Treatment Facility which would allow a good quality secondary effluent release to the sea so minimising the environmental impact. This project had two (2) special problems, firstly remoteness and secondly the Booby Bird that lives at sea and has a high affinity to fresh water. The first problem was solved by good project management and the second by the covering of the Treatment Facility with a tensioned fabric to act as a deflector and both worked well.
Aberdeen Restaurant Enterprises Limited, the owners of the famous Jumbo Restaurant in Hong Kong and part of the Shun Tak Group controlled by the even more famous Stanley Ho, had a serious problem. For some years the Restaurant had discharged to Aberdeen Harbour, and this was no longer acceptable to AREL or the Hong Kong Government.
The Heal group was engaged after a number of other options had been looked at and rejected by AREL. The Heal Group designed, project managed, provided equipment for and commissioned a 1.0 Ml/day Treatment Facility to treat a very strong influent, ie. BOD5 > 800mg/l & NFR > 1200mg/l with very high oils and greases. The result has been an effluent with a BOD5 generally <5.0mg/l and NFR < 10mg/l and a negligible pathogen reading.
This is a view of the Treatment Facility after manufacture at the Panyu Yeufeng Ship Building & Repairing Factory in the Peoples Republic of China. This Treatment Facility is a registered vessel for inland water ways,has been checked by Lloyd's, and has been certified by the H.K. Marine Department and China Classification Society.
The Jumbo Treatment Facility has the task of treating the raw sewage while still remaining in very close proximity to the Restaurants. The deck shot adjacent shows how close the Jumbo Restaurant is and the Jumbo Palace is equally close on the other side.
Odour is controlled by good design principles, and is aided by the use of Zeoflocc which assist in the treatment process and markedly reduces odours within any Treatment Plant.
Remote locations do not mean that wastes do not have to be treated: Papua New Guinea is a good example. The Heal Group has been involved directly in PNG for over ten (10) years, and some staff have grown up in this country. The Heal Group can provide full Treatment facilities in compact Package Plants as well as the more conventional Municipal Works.
The Lihir Gold Project is a good example, being located on a remote island off the coast of New Ireland in PNG and having a very large gold reserve. The Treatment Plants here were designed with wheels so they could be landed from ocean going barges and towed to their location.
To the right we have two (2) Aeration Modules and one (1) Balance Tank Module of a "farm" of Treatment Modules which allow the treatment of 2,500 e.p. of waste water which is to a standard that allows release to the sea without risk or danger to the local population.
We again have a photo of the Lihir Plant with Trainer Operators provided by the PNG Water Board under their commercialisation scheme to ensure high quality operation of the Treatment Facility.
An over shot of the 0.6Ml/day Sewage Facility at Nonga Base Hospital in Rabaul PNG. This Plant is closely located to the Hospital and has to deal with a waste which has a reasonable degree of difficulty. The Plant has an effluent of 20/30 and an Ocean Discharge.
Not only is it necessary to treat Final Effluent, but there is also the need to treat Industrial Waste to allow discharge to sewer. The Plant to the left is to treat, via a Heal Dissolved Air Floatation System, the waste from the TipTop Bakery in Sydney of acceptance to sewer.
