Key food and beverage water treatment technologies include:

We provides a number of technologies for treating water used in the beverage and food industries. Each provides technological solutions for the various stages of water treatment that are required in the food & bev industry.

• Clarification: helps remove suspended solids and particulate matter - usually with the help of flocculants and coagulants, which improve settling.
• Filtration: used for the physical, mechanical and biological separation of solids from treated water.
• Membrane filtration: feed water is forced through a semi-permeable membrane at high pressure to separate specific materials from the solution.
• Softening: water softening involves removing calcium, magnesium and other metal cations using ion exchange resins.
• Deionisation: used for water softening, either cationic or anionic ion-exchange.
• Reverse osmosis: uses membrane separation like membrane filtration.
• Process water polishing: Exceptional solids removal process. It is used for phosphorous removal and water reuse, as well as treating wet weather flows.
• Disinfection with water treatment chemicals and UV: Destroys disease-causing organisms to prevent their spread. Processes such as ozonation and ultraviolet irradiation also aid in the destruction of biological contaminants that remain in the water after treatment.
• Biological treatment: helps upgrade the quality of beverage and food industry effluent being released into the environment and a major component in water recycling from high organic load wastewater.

WATER SOLUTIONS FOR DOWNSTREAM OIL & GAS APPLICATIONS

We offer a complete range of technologies to ensure a secure, safe and reliable water supply, including seawater RO desalination; raw water pretreatment; and process water production, utility water and demineralised water.

Downstream oil & gas processes generate wastewater that requires treatment prior to discharge or reuse. Pollutants such as oils and hydrocarbons, hydrogen sulphide, ammonia, phenols, COD, BOD, mercury, selenium, cyanides and chlorides must be removed to ensure full compliance and appropriate quality.

We provide the full spectrum of wastewater treatment for downstream oil & gas:

• Oil/water separation
• Biological treatment
• Tertiary treatment
• Sludge treatment
• Dissolved and dispersed hydrocarbons removal
• Insoluble hydrocarbons removal

By reusing and recycling water from your effluent treatment plant in downstream operations, companies can significantly lower their water costs, ensure regulatory compliance and minimise environmental impact.

ENGINEERING VALUE ACROSS THE PULP AND PAPER WATER CYCLE

We offer technologies for all aspects of pulp and paper water management within the facility. Our expertise in pulp and paper water treatment reduces water cycle costs and optimizes water consumption per ton of pulp and paper produced.

The pulp and paper industry deals with effluent offering wide potential in reuse and recycling. Plants making the best use of their wastewater significantly lower their production costs. Processes like anaerobic digestion are ideal for pulp and paper wastewater treatment to stabilize sludge and produce biogas for renewable energy.
