Project value: R2 167 951.41
Year of execution: 2021
Plant description: 26 m³/h RO with brine recovery RO water treatment plant
RO is required to remove ions and TDS in the water to produce a low dissolved salt permeate and a concentrated salt waste stream. The system included a brine recovery RO to reduce wastage and achieve a system recovery of 95 %.
High quality input water was still achieved while reducing the overall water wastage of the system. The client also secured their water treatment infrastructure for the next decade by upgrading with modern equipment.
The client needed to discharge ground water contaminated with manganese into a drinking water supply dam. The client required the project to be complete within 4 weeks.
Client: Rural South African community
Location: Thabazimbi, South Africa
Project value: R 494 382.00
Year of execution: 2020
Plant description: 20 m³/h borehole water treatment plant
We installed a system which incorporated pH correction and filtration with catalytic media for to ensure manganese removal as well as hypochlorite dosing for disinfection.
The client was able to treat the water within the required timeframe and could guarantee manganese concentrations below drinking limits.
Cooling towers require chemical dosing to prevent scale, corrosion and the development of biofilm. Additionally, a low conductivity top up system was required to maintain water levels through the system.
Client: Manufacturer of plastic packaging
Location: Johannesburg
Project value: R 416 927.35
Year of execution: 2022
Plant description: 0.5 m3/hr RO system with dosing station
We installed a skid mounted reverse osmosis unit with GAC pretreatment and chemical dosing to control scale, corrosion and biofilm production.
The client was able to enjoy less downtime due to breakdowns and a lower maintenance cost across the system.
The only water source in the area was borehole water, which was contaminated with iron. This posed an operation risk to infrastructure as the water was being used for both potable and process purposes.
Client: Mining Company
Location: Burkina Faso
Project value: R 1 410 151.50
Year of execution: 2022
Plant description: 4 m3/h containerised borehole water treatment plant
BWT installed an iron removal system to ensure safe water for downstream applications.
The client was able to operate their processing facility to the required level and also produce potable water.
The only water source in the area was borehole water, which was contaminated with arsenic and not suitable for human consumption.
Client: Mining Company
Location: Burkina Faso
Project value: R 1 410 151.50
Year of execution: 2022
Plant description: 6 m3/h containerised borehole water treatment plant
BWT installed a reverse osmosis system complete with filtration pre-treatment, including chemical dosing and post remineralisation
Benefit to the Client: The client was able to deliver safe drinking water to the mine community.
A housing estate located outside of the municipal grid supply system was required to provide potable water to the estate homeowners. Borehole water was the only water source, but was high in suspended solids, hardness, dissolved solids and was corrosive.
Client: Housing estate homeowners association
Location: East London
Project value: R 540 000.00
Year of execution: 2022
Plant description: 50 m3/day borehole water treatment plant
We offered filtration, softening and reverse osmosis to address the main challenges with the water. Permeate was disinfected and remineralised with calcite prior to storage.
The client was able to supply safe, potable water to the estate homeowners.
The homeowner wanted to get off the water grid and installed a borehole on his property. The borehole water was contaminated with suspended solids, hardness, iron, manganese and organic carbon.
Client: Private Home
Location: Bedfordview
Project value: R 135 962.00
Year of execution: 2022
Plant description: 500 L/hr Domestic Water Treatment Plant
We installed suspended solids and GAC filtration for solids and organics removal and our inhouse Ecosoft Ecomix media for hardness, iron, and manganese removal. Ozone was used for disinfection.
The homeowner was able to secure their water supply with sufficient quantity and quality to remove themselves from the municipal grid.
Over time, cooling towers can accumulate suspended solids which cause operational challenges in the system.
Client: Vanadium processing facility
Location: Port Elizabeth
Project value: R 194 292.82
Year of execution: 2022
Plant description: Cooling tower side stream filter
Side stream filters are installed to eliminate any build up of suspended material. We supplied AFM filtration with auto backwashing heads.
The client can seamlessly operate their cooling towers by preventing solids build-up in the cooling tower sump and preventing heat transfer in cooling tower.
Problem to be solved: The client wanted to utilise his on-site borehole for his personal use as well as to provide safe drinking water to communities in need. The borehole water was extremely hard and had a high salinity, rendering it unfit for human consumption.
Client: Retailer of borehole water
Location: Centurion
Project value: R 237 624.03
Year of execution: 2021
Plant description: 1 500 L/h borehole water treatment solution
