To produce drinking water from surface water, there often needs to be settlement and filtration steps that generate sludges.
Production of tap water from surface water is mostly based on chemically assisted clarification which generates fluctuating amounts of sludge with changing properties.
Depending on the time of year or current weather, the surface water can be clear, loaded with sediments or subject to algal bloom making sludge dewatering a challenge for many technologies.
The high performance and flexibility of Bucher HPS technology ensures optimum dewatering performances throughout the year. It doesn't matter if you have almost pure hydroxide sludge or high or low organic suspended solid loads. Bucher HPS will always be able to achieve the best possible results.
In fact, the performance of Bucher HPS can reduce the sludge amount to evacuated by up to 50% compared to conventional technologies.
