A method for purification of water with a water purifier. The water purifier includes an anode and a cathode as electrodes in such a way that a gap remains between the anode and the cathode. In the method, an electric field is generated between the anode and the cathode, water for purification is conveyed to the gap and an additive enhancing floc formation is introduced to water for purification or to purified water in an amount of less than 50 g and at least 1 g, measured as dry matter, per each cubic metre of water for purification. Floc material manufactured with the method, when water for purification is municipal wastewater. The use of the floc material produced in this way as a soil conditioner or for manufacturing a soil conditioner.

An adjustable separation system for separating particles suspended in a liquid and method of using same are disclosed. Embodiments are directed to an adjustable separation system that includes an adjustable particle separation channel including: a plurality of plate electrodes; and an adjustable inclination system configured to adjust inclination of the plate electrodes through a range of angles, or an adjustable spacing system configured to adjust spacing between adjacent plate electrodes. The adjustable separation system allows the particle-laden liquid to traverse the plate electrodes within the separation channel, thereby separating the particles from the liquid while using the Boycott effect. These and other embodiments achieve separation of particles suspended in a liquid via an adjustable separation system and, optionally, without the need for manual/technician adjustments, which can result in improved efficiency, quicker separation/operating time, and reduced power consumption and cost.
