Patent number: 9809473Abstract: A water treatment system includes a water mixing unit adapted to promote water turbulence, an input line having an upstream end adapted to be in fluid communication with a body of water to be treated, and a downstream end in fluid communication with the water mixing unit. The system includes an ozone injector adapted to be connected in fluid communication with an ozone gas generation system. A branching line is in fluid communication with the input line and the ozone injector and an ozone supply line is in fluid communication with the ozone injector and the input line. A bypass control valve is in fluid communication with the ozone supply line and the water input line and is adapted to be selectively switched between an open position and a closed position, wherein water is prevented from flowing through the branching line and the ozone supply line when the bypass control valve is in the closed position.Type: GrantFiled: June 26, 2014Date of Patent: November 7, 2017Assignee: Waterco LimitedInventor: Pradeep Kumar Tandon

Patent number: 9016480Abstract: A multi-cyclone sediment filter having a housing with upper and lower shells and defining an interior space for fluid flow. A cyclone holder is disposed in the housing and includes a plurality of fluid cyclones, each comprising a conical tube with a small opening at a lower end and a larger opening at an upper end. A fluid inlet introduces fluid into the filter housing. A fluid outlet in fluid discharges fluid. A manifold plate is disposed above the cyclone holder and includes a plurality of diffuser tubes, each extending downwardly into an upper end of one of the fluid cyclones. Fluid flowing from the fluid inlet is directed into a diverter cone under the manifold plate and is diverted outwardly between the manifold plate and the cyclone holder, into the fluid cyclones, outwardly through the diffuser tubes, and then out through the fluid outlet.Type: GrantFiled: January 8, 2013Date of Patent: April 28, 2015Assignee: Waterco LimitedInventor: Pradeep Kumar Tandon

Patent number: 8348064Abstract: A multi-cyclone sediment filter having a sediment bowl with a hemispherical bottom and a sump for collecting sediment, a cylindrical cyclone housing disposed above and sealingly connected to the sediment bowl, a removable and replaceable cyclone cartridge inserted into the cyclone housing, a diffuser plate sealingly connected to the cyclone cartridge and cyclone housing, a fluid inlet for introducing fluid into the cyclone housing, and a fluid outlet for discharging fluid from the cyclone housing. The cyclone cartridge inserted in the cyclone housing includes a plurality of vertically disposed inverted cone-shaped fluid cyclones, each having a small opening at a lower end and larger opening at an upper end. The cartridge has a plurality of fluid flow paths that direct fluid to the cyclones where a vortex is induced in the moving fluid.Type: GrantFiled: June 20, 2008Date of Patent: January 8, 2013Assignee: Waterco LimitedInventor: Pradeep Kumar Tandon
