Effective and efficient water purification is important in South Africa, where water scarcity is a recurring problem. Accurate dosage and management of water treatment chemicals are key aspects of this process. Blue Reef Water Solutions is a leading South African water treatment company that offers speciality chemicals and outsourced services for a range of industries.
To achieve the specified water quality parameters, controlled chemical dosage is necessary. Inaccurate dosing can lead to major problems, including:
- Ineffective treatment – When contaminants are not fully removed due to underdosing, it can damage equipment and pose health risks.
- Over-treatment – Using too many chemicals can be expensive, produce hazardous byproducts, and have an adverse effect on the environment.
- Process instability – Variations in chemical concentrations disrupt the treatment procedure, which results in varying water quality.
Why is dosing vital to water purification
When adding water treatment chemicals to water to accomplish particular treatment goals, it’s vital to get it right. Typical equipment needed for a dosing setup includes tanks for chemical storage, dosing pumps, metering devices, mixing equipment, pipes and the necessary control panels. Dosing is a process that entails several essential steps:
- Chemical selection – Choosing the right chemicals depends on the target pollutants and the intended treatment result. Coagulants (like alum and ferric chloride), flocculants (like polyacrylamides), disinfectants (like chlorine and ozone), and pH adjusters (like lime and sodium hydroxide) are examples of common water treatment chemicals supplied by Blue Reef.
- Dosing equipment – Delivering the right amount of chemicals at the right rate requires synchronisation of pumps, valves, and metering devices. Solenoid metering pumps, diaphragm pumps, and peristaltic pumps are commonly used because of their accuracy and dependability.
- Control systems – To maintain ideal dosage levels, monitoring and control mechanisms must be put in place. These systems include data gathering devices, controllers (like PID controllers), and sensors (like pH, turbidity, and chlorine residual).
- Distribution and mixing – To encourage effective chemical reactions, the water treatment chemicals and water must be thoroughly mixed. For this, inline injection systems, mechanical mixers, and static mixers are needed.
These factors have a big impact on how effective dosage is. Water chemistry and chemical reactions can be influenced by temperature, pH, and the presence of other substances. In addition, the correct flow rate is needed to maintain constant water treatment. Any variations in water flow will require modifying the dose rate.
Which industries need dosing and control
Precise chemical dosing is essential for water filtration in many local and international industries. To start, municipalities have a mandate to provide communities with clean drinking water, so water purification chemicals need to be used but at precise dosages so as not to affect the taste or quality of the water.
Many industrial facilities need to remove contaminants from effluent water. Accurate dosing can ensure the cleanliness of wastewater will not have adverse effects on the environment and downstream ecosystems. Similarly, in food and beverage manufacturing, ensuring product quality and adhering to strict sanitary regulations is reliant upon accurate dosing and water purification.
Power generation is another industry that relies on dosing. It is used to prevent corrosion and scale by treating cooling and boiler feed water. These systems need to be precise and work correctly to maximise the efficiency of equipment and maintain acceptable water quality standards.
