Siltbuster’s latest concrete washwater treatment system is designed to be compact and more versatile than previous versions, making it ideal for contractors working on smaller projects.
The pHD system was developed in response to the Environment Agency’s position paper on concrete washwater that calls for contractors to take more care when disposing of wastewater generated during concreting works.
The unit can be used with either existing concrete washout skips or in conjunction with Siltbuster’s new range of concrete washwater handling equipment to provide accurate and automated pH correction.
The system works by pushing micro bubbles of carbon dioxide gas into the washwater where they dissolve to reduce the pH of the water.
According to Siltbuster, the new pHD system has a number of benefits over other systems. It says the unit avoids the health and safety risk associated with handling acids normally used for pH adjustment, while digital control eliminates the risk of over or under adjustment.
