BOC’s water and wastewater treatment processes can be used to eliminate odors, treat volatile fatty acids, remove micro-pollutants, achieve optimal biological oxygen demand, control wastewater or raw water pH or water remineralisation. BOC can support you with a range of application technologies engineered to deliver the best results in a cost-effective way.
BOC has been involved in many projects ranging from wastewater to drinking water applications, surface water and process water. We also have a number of installations in Western Australia where we oxygenate rivers to maintain fish life during unfavourable natural conditions.
Our SOLVOX® technologies will support your plant aerobic treatment needs, whereas the SOLVOCARB® line offers a diversity of solutions for neutralisation and remineralisation with carbon dioxide. We also design and deliver oxygen supply schemes and oxygen recycle for ozone generation, which can help you save up to 60% of oxygen.
Aerobic Wastewater Treatment With Oxygen Using Aeration Technologies
The best way to fight odors in the wastewater industry, is to add pure oxygen to your existing process, which can raise the level of dissolved oxygen enough to reduce or eliminate odors without further action.
Based on decades of experience, BOC has developed a complete portfolio of oxygenation equipment to meet customers' aeration and mixing needs. Our turnkey solutions include gas dosing equipment, electrical control systems and the full support of our engineers for installation advice, supervision and commissioning services. Our portfolio is compatible with existing equipment and therefore can be used to complement systems already in use. From temporary to permanent oxygenation solutions and from low to high oxygen demand, you can count on us to find the best option to address your specific challenges.
Neutralisation And Remineralisation With CO₂
The SOLVOCARB® portfolio includes reliable gas supply schemes and efficient injection equipment to perform neutralisation and remineralisation treatments with carbon dioxide. Our engineers will assist you with extensive know-how to make sure that all processes run smoothly, from installation to operation.
BOC will provide you with fully tested and competitively priced metering and dissolving systems for carbon dioxide. The application equipment of the SOLVOCARB® family can be applied flexibly in an in-line or bypass operation, thus offering a broad range of solutions to meet specific customer requirements.
Water Treatment With Ozone
Ozone has been used in water treatment for a long time to get rid of contaminants and to reduce micro-pollutants in drinking water and for treating industrial wastewater with a high chemical oxygen demand (COD) as found in the textile, pharmaceutical and specialty chemicals industries.
Recently, more and more countries have been introducing regulations for the residual micro-pollutants in treated wastewater after conventional municipal biological treatment. Various advanced oxygenation process treatment trains have been tested for this purpose, and ozone has been proven to be very effective in dealing with these compounds.
In the corona-discharge production process, ozone is created by an electrical discharge to ambient air or oxygen. When using highly concentrated or pure oxygen instead of ambient air for the production of ozone, the following advantages arise:
- Higher ozone production
- Smaller footprint
- No pre-treatment of the feed gas is required
