WASTE WATER TREATMENT home
Reaman Industries offers a wide variety of individually styled, environmentally sound, waste water treatment alternatives, equally suited to tourism, local authority, commercial and industrial markets.
We offer a turnkey approach to waste water treatment. From initial concept to installation, commissioning and the most important facet of all, after-care and management. This allows for treated effluent to be recycled for toilet/urinal flushing and irrigation, and for treated sludge to be on-used for soil conditioning or composting purposes.
Sequence Batch Reacting (SBR)
Our SEBAS SBR technology uses single or multiple tanks (Reactors), basins or lagoons, with either intermediate or continuous influent, but with cyclic aeration and decanting of the treated effluent.
The SBR process is able to achieve a consistently high effluent quality with regard to BOD's and suspended solids reduction.
This quality wastewater system can safely discharge effluent to land or water without affecting the environment.
This means that our SEBAS SBR Waste Water Treatment Plants have a number of applications suitable for tourist resorts, small and large communities, industrial and leachate effluent streams.
The resultant treated effluent can also be safely recycled for toilet and urinal flushing, thus conserving scarce fresh water supplies.
Irrigation of tourist and hotel gardens, nurseries, etc can be carried out all year round, thus providing the restful ambience to which these discerning properties aspire.
The treated effluent in storage tanks can provide remote hotel and resorts with fire-fighting capabilities over and above swimming pools, or fresh water storage.

Rotating Biological Contactors (RBC)
Our S&P Rotating Biological Contactors (RBC) Waste Water Treatment Plants provide a simple, low cost, but effective means of treating waste waters. The RBC process can achieve effluent quality results of:
BOD5 20 mg/L
TSS 20 mg/L
With tertiary filtration treatment we can further reduce these levels to:
BOD5 10 mg/L
TSS 10 mg/L
Nutrient removal can also be achieved by recycling a varying percentage of the effluent back through the Waste Water Treatment Plant.
The treated effluent can be discharged to overhead irrigation systems (after disinfecting), or to subsoil irrigation systems, which do not require the effluent to be disinfected.
Containerised Waste Water Treatment Plants
We manufacture and supply S&P RBC Waste Water Treatment Plants mounted in standard ISO 20ft and 40ft containers for either portable or fixed installations.
Flows in excess of 250m per day can be catered for and the plants can be designed for any conditions, from arctic to tropical.

Waste Water Treatment Plants - Management and Maintenance Programmes
We offer the following services:
- 1. Review and reporting on conditions of your existing Waste Water Treatment Plants with a view to reducing operating costs.
- 2. Advice and budgetary costing of upgrades for poorly operating Waste Water Treatment Plants, that will achieve substantial increase in effluent qualities and reductions in operating costs.
- 3. Maintenance schedules and costs for three monthly, six monthly or annual servicing of Waste Water Treatment Plants. This includes written reports on completion of each service.
- 4. Ongoing operational support on a daily/weekly basis for plant operators and owners of Waste Water Treatment Plants.

Description
The Te Maunga Waste Water Treatment Plant (WWTP) provides wastewater treatment for the domestic, commercial and industrial communities from the Mount Maunganui and Papamoa catchments. The WWTP is located south of Tauranga and was commissioned during 1996. The first upgrade took place in the year 2000, which entailed modifications to the aeration control and distribution system and the installation of additional diffusers. The plant was designed as an extended aeration activated sludge system, utilising an oxidation ditch configuration.
The modifications to the bioreactor and the provision of additional aeration capacities resulted in doubling the organic and hydraulic capacity of the existing plant (from 8,000 m3/d to 16,000 m3/d) and controlling nitrogen removal more effectively.
The design of the aeration system was critical to ensure that minimal disruptions and downtime occurred during the removal of the existing ceramic diffusers and the installation of new banks of diffusers. Divers were used to install brackets on the tank floor. Tube type silicon membrane diffusers were installed in all the aeration zones. The banks of diffusers are removable and can be lifted out of the tanks using a 50-tonne crane.
The removal of the existing diffusers, the installation of the new banks of diffusers and the connection and extension of the existing pipe header had to be carried out progressively, to ensure continued treatment of the incoming wastewater.
Completed on time and under budget.
- A 20% overall site power saving, which equates to at least 30% power saving on the aeration system as reflected in lower airflow requirements
- Lower utilisation of blowers, hence longer life expectancy
- Doubling the treatment capacity from 32,000 EP to 64,000 EP
